# Peer Community in Ecotoxicology & Environmental Chemistry, un nouveau média ouvert, transparent et gratuit pour la valorisation et la diffusion de vos recherches

## Que sont les Peer Community In... ?

Les Peer Community In... (PCI, https://peercommunityin.org/) sont des communautés scientifiques qui organisent des processus éditoriaux de science ouverte. Il s'agit de communautés spécialisées effectuant une évaluation scientifique par les pairs et à la demande des auteurs, de preprints déposés sur des serveurs de preprints ou des archives ouvertes institutionnelles. Dans chaque PCI, les recommandeurs, qui sont les équivalents des éditeurs scientifiques de revues, constituent une équipe de reviewers qui réalisent une évaluation détaillée de l'article. S'ensuit une décision éditoriale qui mène soit au rejet, soit à la demande de corrections, soit à la validation de l'article scientifique, éventuellement après plusieurs rounds d'évaluation. Dans ce dernier cas, le recommandeur écrit un texte de recommandation dans lequel il explique pourquoi il a validé l'article. L'ensemble de la communauté scientifique a ainsi accès gratuitement au contenu validé de l'article et aux évaluations/recommandations. Les PCIs ne publant pas les articles recommandés, les auteurs peuvent éventuellement le soumettre pour publication dans une revue scientifique de leur choix et notamment dans les revues qui se sont déclarées PCI-friendly. Les éditeurs en chef de ces revues se sont engagés à prendre en compte, dans les cas appropriés, les évaluations et recommandations des PCIs pour compléter/accélérer leur processus éditorial, débouchant régulièrement sur une acceptation en l'état des preprints recommandés par PCI. Notons que les relations entre les PCIs et les revues scientifiques évoluent. A l'avenir un PCI-friendly ou un PCI-partner journal sera une revue de société savante, ou d'institut de recherche ou publiant en Open Access gratuit ou publié par un éditeur non lucratif. Les PCI-friendly journals s'engageront à fournir une réponse aux auteurs en 5 jours (pas intéressés acceptation sans reviews supplémentaires ou reviews supplémentaires nécessaires). Les PCI-partner journals s'engagent à accepter les articles recommandés sans reviews supplémentaires.

Une courte vidéo sur PCI: https://www.youtube.com/watch?v=4PZhpnc8wwo

L'objectif du PCI est d'évaluer et de recommander des preprints. Les preprints recommandés sont des articles valides, citables et finalisés. Le résultat normal est donc de les laisser sur des serveurs de preprint ou des archives ouvertes.

Cependant, les auteurs d'un article recommandé par PCI peuvent préférer :

* Le publier dans la revue PCI tel quel, immédiatement et sans frais.

* Le soumettre à une revue PCI-partner (acceptation de l'article "tel quel" ou sans autre examen par les pairs) ou à une revue PCI-friendly (réponse dans les 5 jours). Les revues PCI-partner et PCI-friendly sont ou bien des revues en libre accès Diamond, ou des revues de sociétés, ou des revues d'institutions de recherche ou des revues publiées par des éditeurs à but non lucratif.

* Le soumettre à d'autres revues, dont beaucoup peuvent utiliser l'évaluation faite par PCI si elles la jugent approprié.

## Peer Community in Ecotoxicology and Environmental Chemistry (PCI EcotoxEnvChem)

Peer Community in Ecotoxicology and Environmental Chemistry fait partie des 13 PCI existant à ce jour. Les articles rentrant dans le champ de PCI Ecotox Env Chem concernent des travaux originaux (observations, expérimentations, modélisations, approches théoriques...) qui permettent des avancées significatives de la connaissance dans les champs de l'écotoxicologie terrestre et aquatique, ainsi que de la chimie de l'environnement. PCI Ecotox Env Chem considère la dynamique et le transport des composés chimiques dans l'environnement, leur transfert vers les organismes au sein des réseaux trophiques, et leurs effets à différents niveaux d'organisation biologique et géographique. Ainsi, PCI Ecotox Env Chem intègre différentes disciplines et approches qui répondent aux problématiques d'écotoxicologie et de toxicologie de l'environnement : chimie analytique, physiologie, microbiologie, génétique, génomique, ingénierie environnementale, modélisation, science des données, évaluation des risques... PCI Ecotox Env Chem dispose à ce jour d'un panel international de 25 recommandeurs, et développe son partenariat avec les réseaux scientifiques et sociétés savantes, ainsi qu'avec des journaux partenaires.

## Comment soumettre in preprint à PCI EcotoxEnvChem ?

Les PCI dans l'évaluation institutionnelle des chercheurs

Les articles recommandés par des PCIs sont de plus en plus considérés dans les dossiers d'évaluation des
chercheurs, des unités et des projets. Par exemple, les sections 29, 30 and 52 du CoNRS, la section 67 du
CNU, des CSS d'INRAE, etc. (voir le détail sur : https://peercommunityin.org/pci-network/) ont publié des
motions dans ce sens. Cette reconnaissance doit être étendue plus généralement en France et à l'étranger.
De nombreuses écoles doctorales considèrent également les articles recommandés par une PCI comme ayant
la même valeur à priori que des articles publiés de bonne qualité dans des revues scientifiques. Elles
permettent ainsi à leurs étudiants de soutenir leur thèse avec des articles recommandés par une PCI.

Long-term multi-endpoint
exposure of the microalga
Raphidocelis subcapitata to
lanthanum and cerium

Authors: Siciliano A, Guida M, Serafini S et al.

Source: SCIENCE OF THE TOTAL ENVIRONMENT
790: 148229, 2021, DOI 10.1016/j.scitotenv.2021.148229

**Abstract:** Significant release of rare earth elements (REEs) into the environment is mainly due to active or abandoned mining sites, but their presence is globally increasing due to their use in several industrial sectors. The effects on primary producers as Raphidocelis subcapitata are still limited. This research focused on La and Ce as the two most widespread REEs that can be currently found up to hundreds of µg/L in water and wastewater. Microalgae were exposed to La and Ce for 3 days (pH = 7.8) (short-term exposure) to derive the effective concentrations inhibiting the growth on 10% (EC10) of the exposed population. EC10 values (0.5 mg/L of La and 0.4 mg/L of Ce) were used for the 28 days long-term exposure (renewal test) to observe after 7, 14, 21, and 28 days on a multi-endpoint basis microalgae growth inhibition, biomarkers of stress (reactive oxygen species, superoxide dismutase, and catalase), and bioconcentration...

**Abstract:** Glyphosate herbicide is ubiquitously used in agriculture and weed control. It has now been identified in aquatic ecosystems worldwide, where numerous studies have suggested that it may have both suppressive and stimulatory effects on diverse non-target organisms. We cultured natural biofilms from a hypereutrophic environment to test the effects on periphytic diatoms of exposure to a glyphosate-based herbicide formulation at concentrations from 0 to 10 mg L-1 of active ingredient...

Resistance, resilience, and
functional redundancy of
freshwater bacterioplankton
communities facing a gradient
of agricultural stressors in a
mesocosm experiment

Authors: da Costa NB, Fugere V, Hebert MP et al.

Source: MOLECULAR ECOLOGY Early Access, 2021, DOI 10.1111/mec.16100

**Abstract:** Agricultural pollution with fertilizers and pesticides is a common disturbance to freshwater biodiversity. Bacterioplankton communities are at the base of aquatic food webs, but their responses to these potentially interacting stressors are rarely explored. To test the extent of resistance and resilience in bacterioplankton communities faced with agricultural stressors, we exposed freshwater mesocosms to single and combined gradients of
two commonly used pesticides: the herbicide glyphosate (0-15 mg/L) and the neonicotinoid insecticide imidacloprid (0-60 µg/L), in high or low nutrient backgrounds. Over the 43-day experiment, we tracked variation in bacterial density with flow cytometry, carbon substrate use with Biolog EcoPlates, and taxonomic diversity and composition with environmental 16S rRNA gene amplicon sequencing...

Humic substances modulate
fish bacterial communities in
a marine recirculating
aquaculture system

Authors: Louvado A, Cleary DFR, Pereira LF et al.

Source: AQUACULTURE 544: 737121, 2021, DOI 10.1016/j.aquaculture.2021.737121

**Abstract:** The stressful conditions of intensive aquaculture systems, combined with excessive antibiotic use, may have dysbiotic effects on aquaculture microbiomes and promote the spread of opportunistic pathogens. Here, we hypothesized that humic substances (HS), when added to the rearing water of a marine recirculating aquaculture system (RAS), will act as a chemical modulator of fish-associated bacterial communities and suppress potential pathogens. To test this, a 28-day RAS trial for juvenile European sea bass (Dicentrarchus labrax) was conducted with and without HS modulation. High-throughput sequencing of the 16S rRNA gene was used to evaluate role of HS in modulating fish bacterial assemblages (gut and skin mucus). In addition to this, biometric, digestive and oxidative stress parameters were measured to assess the impact of HS on fish performance...

# The microalga *Phaeocystis antarctica* is tolerant to salinity and metal mixture toxicity interactions

**Authors:** Koppel DJ, Whitelaw N, Adams MS et al.

**Source:** ENVIRONMENTAL SCIENCE-PROCESSES & IMPACTS, Early Access, 2021, DOI 10.1039/d1em00233cE

**Abstract:** Salinity in the Antarctic nearshore marine environment is seasonally dynamic and climate change is driving greater variability through altered sea ice seasons, ocean evaporation rates, and increased terrestrial ice melt. The greatest salinity changes are likely to occur in the nearshore environment where elevated metal exposures from historical waste or wastewater discharge occur. How salinity changes affect metal toxicity has not yet been investigated. This study investigated the toxicity of cadmium, copper, nickel, lead, and zinc, and their equitoxic mixtures across a salinity gradient to the Antarctic marine microalga *Phaeocystis antarctica...*

# Combined impacts of photosystem II-inhibiting herbicides and light availability on seagrass and marine microalgae

**Authors:** King OC, Smith RA, Warne MS et al.

**Source:** MARINE ECOLOGY PROGRESS SERIES 668: 215-230, 2021, DOI 10.3354/meps13717
**Abstract:** The combined and interactive effects of multiple stressors threaten coastal ecosystems, yet most ecological risk assessments used to inform environmental management still treat stressors separately. For marine microalgae and seagrass—particularly those common to the Great Barrier Reef, Australia-key stressors include low light from increased turbidity and herbicide exposure that runs off agricultural land. Despite co-occurring in aquatic ecosystems, the effects of these stressors are often studied separately, meaning any combined or interactive effects are overlooked. Here, we aimed to develop a conceptual synthesis of the physiological responses of marine microalgae and seagrass when exposed to these key stressors...

## Biochemical Effects of Two Pesticides in Three Different Temperature Scenarios on the Diatom *Thalassiosira weissflogii*

Authors: Mesquita AF, Goncalves FJM, Rocha CP et al.

Source: PROCESSES 9: 1247, 2021, DOI 10.3390/pr9071247

**Abstract:** The exponential increase of the human population demands the overuse of fertilizers and pesticides in agriculture practices to suppress food production needs. [...] Besides the known effects of such products in organisms, climatic changes pose an additional issue, being a main concern among scientists and politicians worldwide, since these alterations may worsen ecosystems' and organisms' sensitivity to stress conditions, such as the exposure to pollutants. [...] However, few studies have evaluated the biochemical impacts of oxyfluorfen and copper sulfate exposure on diatoms. This study intends to (1) evaluate the effects on the growth rate of both
contaminants on *T. weissfloggi* at three temperatures, considering the actual scenario of climatic changes, and (2) assess biochemical changes on the diatom when exposed to the chemicals at different temperatures. To achieve these aims, the marine diatom was exposed to the two chemicals individually at different temperatures...

**Authors:** Mishra S, Pang SM, Zhang WP and more...

**Source:** CHEMOSPHERE 279, 2021, DOI 10.1016/j.chemosphere.2021.130500

**Abstract:** Carbamate compounds are commonly applied in agricultural sectors as alternative options to the recalcitrant organochlorine pesticides due to their easier breakdown and less persistent nature. However, the large-scale use of carbamates also leads to toxic environmental residues, causing severe toxicity in various living systems. The toxic effects of carbamates are due to their inhibitor activity against the acetylchlolinesterase enzyme. This enzyme is crucial for neurotransmission signaling in living beings. Hence, from the environmental point of view, the elimination of carbamates is a worldwide concern and priority. Microbial technology can be deliberated as a potential tool that can work efficiently and as an ecofriendly option for the dissipation of carbamate insecticides from contaminated environments by improving biodegradation processes via metabolic activities of microorganisms...

**Source:** Environmental Pollution 283, 2021, 117095, DOI 10.1016/j.envpol.2021.117095

**Abstract:** Chlordane is an organochlorine pesticide that is applied extensively. Residual concentrations that remain in soils after application are highly toxic to soil organisms, particularly affecting the earthworm gut and indigenous soil microorganisms. However, response mechanisms of the earthworm gut and indigenous soil microorganism communities to chlordane exposure are not well known. In this study, earthworms (Metaphire guillelmi) were exposed to chlordane-contaminated soils to investigate their response mechanisms over a gradient of chlordane toxicity...

Authors: Miloloza M, Bule K, Ukic S et al.

Source: WATER AIR AND SOIL POLLUTION 232:327, 2021, DOI 10.1007/s11270-021-05267-0

**Abstract:** An extensive use of plastic material, which is a characteristic of modern society, is increasing the amount of plastic waste in the environment. Accordingly, plastic pollution has become a global environmental problem. The problem is particularly related to microsized and nanosized plastic particles which have become environmental contaminants of emerging concern. This research was focused on ecotoxicological aspects of 5 the most common
plastic substances: polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), and polyethylene terephthalate (PET); all substances were in form of microplastics. The used test organism was freshwater microalgae Chlorella sp. and inhibition of the algal growth after 3-day exposure was measured. The experimental domain included microplastics in range 10-1000 mg/L and sizes 100-700 µm. Response surface modeling was applied in order to analyze the influence of these two parameters and statistical analysis of the obtained models was performed...

## Contribution of microplastic particles to the spread of resistances and pathogenic bacteria in treated wastewaters

**Authors:** Galafassi S, Sabatino R, Sathicq MB et al.

**Source:** WATER RESEARCH 201: 117368, 2021, DOI 10.1016/j.watres.2021.117368

**Abstract:** Microplastic Particles (MPs) are ubiquitous pollutants widely found in aquatic ecosystems. Although MPs are mostly retained in wastewater treatment plants (WWTPs), a high number of MPs reaches the open waters potentially contributing to the spread of pathogenic bacteria and antibiotic resistance genes in the environment. Nowadays, a limited number of studies have focused on the role of MPs as carriers of potentially pathogenic and antibiotic resistant bacteria in WWTPs. Thus, an investigation on the community composition (by 16S rRNA gene amplicon sequencing) and the abundance of antibiotic and metal resistance genes (by qPCR) of the biofilm on MPs (the plastisphere) and of planktonic bacteria in treated (pre- and post-disinfection) wastewaters was performed...

## Microplastics can act as vector of the biocide triclosan exerting damage to freshwater microalgae

**Authors:** Verdu I, Gonzalez-Pleiter M, Leganes F et al.

**Source:** CHEMOSPHERE 266: 129193, 2021, DOI 10.1016/j.chemosphere.2020.129193

**Abstract:** Despite the large number of recent studies on microplastics (MPs) and their ability to act as carriers of pollutants, the knowledge about the biological effects of MPs loaded with chemicals is scarce. The aim of this study was to evaluate the potential of MPs as vectors for the antimicrobial triclosan (TCS). For it, we tested low-density polyethylene, polyamide, polyethylene terephthalate, polyoxy-methylene, polypropylene, polystyrene and the biodegradable polylactic acid. Thus, chemical analysis of sorption and desorption of TCS by these MPs was evaluated. The effect of TCS-loaded MPs to *Anabaena* sp. PCC7120, a cyanobacterium model of primary producers in freshwater ecosystems, was investigated...

# Understanding the Fundamental Basis for Biofilm Formation on Plastic Surfaces: Role of Conditioning Films

**Authors:** Bhagwat G, O'Connor W, Grainge I, Palanisami T

**Source:** FRONTIERS IN MICROBIOLOGY 12: 687118, 2021, DOI 10.3389/fmicb.2021.687118

**Abstract:** Conditioning films (CFs) are surface coatings formed by the adsorption of biomolecules from the surrounding environment that can modify the material-specific surface properties and precedes the attachment of microorganisms. Hence, CFs are a biologically relevant identity that could govern the behavior and fate of microplastics in the aquatic environment. In the present study, polyethylene terephthalate and polylactic acid plastic cards were immersed in natural seawater to allow the formation of CFs. The changes in the surface roughness after 24 h were investigated by atomic force microscopy, and the surface changes were visualized by scanning electron microscopy...

**Source:** MICROBIOME 9: 141, 2021, DOI 10.1186/s40168-021-01054-5

**Abstract:** Plastics now pollute marine environments across the globe. On entering these environments, plastics are rapidly colonised by a diverse community of microorganisms termed the plastisphere. Members of the plastisphere have a myriad of diverse functions typically found in any biofilm but, additionally, a number of marine plastisphere studies have claimed the presence of plastic-biodegrading organisms, although with little mechanistic verification. Here, we obtained a microbial community from marine plastic debris and analysed the community succession across 6 weeks of incubation with different polyethylene terephthalate (PET) products as the sole carbon source, and further characterised the mechanisms involved in PET degradation by two bacterial isolates from the plastisphere...

# Understanding nanoplastic toxicity and their interaction with engineered cationic nanopolymers in microalgae by physiological and proteomic approaches

**Authors:** Tamayo-Belda M, Vargas-Guerrero JJ, Martin-Betancor K et al.

**Source:** ENVIRONMENTAL SCIENCE-NANO Early Access, 2021, DOI 10.1039/d1en00284h

**Abstract:** The amount of plastics produced per year is in constant growth alongside their use in different sectors like the textile industry, agriculture or, more recently, in nanotechnology. Under certain environmental conditions, plastics break down into smaller pieces. Those plastics in the nanosize range are the most difficult to identify, quantify and remove and therefore probably prevail in aquatic ecosystems. Likewise, nanomaterial production has been increasing exponentially and therefore their potential release to the environment poses a threat. There is a lack of knowledge regarding the combined effects of co-occurring nanopolymers on biota. In this work, we have studied the individual toxicity of polystyrene nanoplastics (PS-NPs) as well as their combined effect with generation 7 PAMAM dendrimers (G7) on the filamentous cyanobacterium *Anabaena* sp. PCC7120, a relevant aquatic primary producer...

## Vegetation shapes aboveground invertebrate communities more than soil properties and pollution: a preliminary investigation on a metal-contaminated site

Authors: Ozaki S, Fritsch C, Mora F, Cornier T et al.

Source: ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH Early Access, 2021, DOI 10.1007/s11356-021-15811-4

**Abstract:** Pollution with trace metals (TM) has been shown to affect diversity and/or composition of plant and animal communities. While ecotoxicological studies have estimated the impact of TM contamination on plant and animal communities separately, ecological studies have widely demonstrated that vegetation is an important factor shaping invertebrate communities. It is supposed that changes in invertebrate communities under TM contamination would be explained by both direct impact of TM on invertebrate organisms and indirect effects due to changes in plant communities. However, no study has clearly investigated which would more importantly shape invertebrate communities under TM contamination. Here, we hypothesized that invertebrate communities under TM
contamination would be affected more importantly by plant communities which constitute their habitat and/or food than by direct impact of TM...

## Antibacterial and anatomical defenses in an oil contaminated, vulnerable seaduck

**Authors:** Moller AP, Laursen K, Izaguirre J, Marzal A

**Source:** ECOLOGY AND EVOLUTION Early Access, 2021, DOI 10.1002/ece3.7996

**Abstract:** Oil spills have killed thousands of birds during the last 100 years, but nonlethal effects of oil spills on birds remain poorly studied. We measured phenotype characters in 819 eiders Somateria mollissima (279 whole birds and 540 wings) of which 13.6% were oiled. We tested the hypotheses that (a) the morphology of eiders does not change due to oil contamination; (b) the anatomy of organs reflects the physiological reaction to contamination, for example, increase in metabolic demand, increase in food intake, and counteracting toxic effects of oil; (c) large locomotion apparatus that facilitates locomotion increases the risk of getting oiled; and (d) individual eiders with a higher production of secretions from the uropygial grand were more likely to have oil on their plumage. We tested whether 19 characters differed between oiled and nonoiled individuals, showing a consistent pattern...

## Effects of the anxiolytic benzodiazepine oxazepam on freshwater gastropod reproduction: a prospective study

**Authors:** Lebreton M, Malgouyres JM, Carayon JL, Bonnafe E et al.

**Source:** ECOTOXICOLOGY Early Access, 2021, DOI 10.1007/s10646-021-02453-y

**Abstract:** Psychoactive drugs have emerged as contaminants over the last few decades. These drugs are frequently prescribed and poorly eliminated by wastewater treatment plants, and many are present at non-negligible concentrations in surface waters. Several studies have investigated the non-target organism toxicity of one such drug, oxazepam, a benzodiazepine anxiolytic frequently detected in rivers. However, very little is known about the impact of this drug on reproduction. We investigated the effects of environmentally relevant concentrations of oxazepam on *Radix balthica*, a freshwater gastropod widespread in Europe...

## The contributions of enchytraeids and earthworms to the soil mineralization process in soils with fungicide

**Authors:** Pelosi C, Thiel P, Bart S, Amosse J et al...

**Source:** ECOTOXICOLOGY Early Access, 2021, DOI 10.1007/s10646-021-02452-z

**Abstract:** Pesticides may harm soil organisms such as earthworms and enchytraeids, but knowledge is lacking on their relative sensitivity to these chemicals and the consequences on soil functions. The aim of this study was to assess the impact of exposure to a commercial fungicide formulation (Swing (R) Gold, containing dimoxystrobin and epoxiconazole) on the function of earthworms (*Aporrectodea caliginosa*) and enchytraeids (*Enchytraeus buchholzi*) in soil organic matter (SOM) mineralization. The soil organisms were incubated alone and together in a 26-day laboratory experiment...

[10.1016/j.scitotenv.2021.148223](https://doi.org/10.1016/j.scitotenv.2021.148223)

**Abstract:** A comprehensive study of the toxicity of lanthanides (LN) in relation to the media composition will enhance the prediction of their potential adverse effects for living organisms. Here we examined the effect of different media on the *V. faba* root elongation and on the cytotoxic (mitotic index) and the genotoxic (micronucleated cell number) effects from toxicity tests with Ce, Gd and Lu (100, 800 and 6400 µg L-1). Three different exposure media were selected: the standard Hoagland media (SH); an alternative SH, without phosphates (SH-P); and distilled water (DW)...

[10.3390/molecules26154574](https://doi.org/10.3390/molecules26154574)

**Abstract:** FINEAU (2021-2024) is a trans-disciplinary research project involving French, Serbian, Italian, Portuguese and Romanian colleagues, a French agricultural cooperative and two surface-treatment industries, intending to propose chenevotte, a co-product of the hemp industry, as an adsorbent for the removal of pollutants from polycontaminated wastewater. The first objective of FINEAU was to prepare and characterize chenevotte-based materials. In this study, the impact of water washing and treatments (KOH, Na2CO3 and H3PO4) on the composition and structure of chenevotte (also called hemp shives) was evaluated using chemical analysis, X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, X-ray computed nanotomography (nano-CT), attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, solid state NMR spectroscopy and thermogravimetric analysis...

**Letter:** Bees and other pollinators play vital roles in biodiversity and food security, and they are a source of income and inspiration. Yet, bees' biodiversity and abundance are decreasing every day. Their decline, driven by pesticides (1-3), poses serious threats to the environment, ecosystems, and human health. The European pesticide authorization framework states that a pesticide can only be put on the market if it has no harmful effects on human health or animal health and no unacceptable effects on the environment (4). EU ministries met in June to decide what constitutes an "acceptable" effect of a pesticide on bees (5)...
# Mercury accumulation in the sediment of the Western Mediterranean abyssal plain: A reliable archive of the late Holocene

**Authors:** Cossa D, Mucci A, Guedron S, Coquery M et al...

**Source:** GEOCHIMICA ET COSMOCHIMICA ACTA 309: 1-15, 2021, DOI 10.1016/j.gca.2021.06.014

**Abstract:** Temporal reconstruction of Hg deposition from sediment archives is relatively straightforward in organic-rich or high sedimentation rate environments, such as lakes and ocean margins. To retrieve long-term records at regional or global scales, deep-sea sediments are more appropriate, but such records are scarce and their reliability has been questioned because of possible post-depositional Hg diagenetic remobilization. Here, we investigated the accumulation of Hg in the Balearic Abyssal Plain (2850 m deep) of the Western Mediterranean through a comprehensive characterization of the chemical and isotopic composition (organic carbon, nitrogen, sulfur, major and redox-sensitive elements) of sediment trap material and sediment cores...

# Introducing ground cover management in pesticide emission modeling

**Authors:** Gentil-Sergent C, Basset-Mens C, Renaud-Gentie C, Mottes C et al.

**Source:** INTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT Early Access, 2021, DOI 10.1002/ieam.4482

**Abstract:** Ground cover management (GCM) is an important agricultural practice used to reduce weed growth, erosion and runoff, and improve soil fertility. In the present study, an approach to account for GCM is proposed in the modeling of

pesticide emissions to evaluate the environmental sustainability of agricultural practices. As a starting point, we include a cover crop compartment in the mass balance of calculating initial (within minutes after application) and secondary (including additional processes) pesticide emission fractions. The following parameters were considered: (i) cover crop occupation between the rows of main field crops, (ii) cover crop canopy density, and (iii) cover crop family. Two modalities of cover crop occupation and cover crop canopy density were tested for two crop growth stages, using scenarios without cover crops as control. From that, emission fractions and related ecotoxicity impacts were estimated for pesticides applied to tomato production in Martinique (French West Indies) and to grapevine cultivation in the Loire Valley (France)...

# In situ and ex situ bioassays with *Cantareus aspersus* for environmental risk assessment of metal(loid) and PAH-contaminated soils

**Authors:** Louzon M, Pauget B, Gimbert F, Morin-Crini N et al.

**Source:** INTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT Early Access, 2021, DOI 10.1002/ieam.4480

**Abstract:** Environmental risk assessment of contaminated soils requires bioindicators that allow the assessment of bioavailability and toxicity of chemicals. Although many bioassays can determine the ecotoxicity of soil samples in the laboratory, few are available and standardized for on-site application. Bioassays based on specific threshold values that assess the in situ and ex situ bioavailability and risk of metal(loid)s and polycyclic aromatic hydrocarbons (PAHs) in soils to the land snail *Cantareus aspersus* have never been simultaneously applied to the same soils. The aims of this study were to compare the results provided by in situ and ex situ bioassays and to determine
their respective importance for environmental risk assessment. The feasibility and reproducibility of the in situ bioassay were assessed using an international ring test...

## Functional and Taxonomic Diversity of Collembola as Complementary Tools to Assess Land Use Effects on Soils Biodiversity

**Authors:** Joimel S, Schwartz C, Bonfanti J, Hedde M et al...

**Source:** FRONTIERS IN ECOLOGY AND EVOLUTION 9: 630919, 2021, DOI 10.3389/fevo.2021.630919

**Abstract:** Collembola have been proposed for several decades as a good model organisms to survey soil biodiversity; but most of the studies focused on taxonomic endpoints. The main objectives of this study are to compare the effects of the different land uses, including urban and industrial land uses, while using both collembolan functional and taxonomic biodiversity approaches. We collected data on 3,056 samples of Collembola communities across 758 sites in various land uses throughout France. The types of land use considered included all types of human activity from forestry to urban, industrial, traffic, mining and military areas, agricultural grassland, arable land, vineyards and urban vegetable gardens. In order to study functional and taxonomic biodiversity, we used community-weighted means, functional indices, species richness and density...

## Biosorbents from Plant Fibers of Hemp and Flax for Metal Removal: Comparison of Their Biosorption Properties

**Authors:** Mongiovi C, Morin-Crini N, Lacalamita D, Bradu C et al.

**Source:** MOLECULES 26(14): 4199, 2021, DOI 10.3390/molecules26144199

**Abstract:** Lignocellulosic fibers extracted from plants are considered an interesting raw material for environmentally friendly products with multiple applications. This work investigated the feasibility of using hemp- and flax-based materials in the form of felts as biosorbents for the removal of metals present in aqueous solutions. Biosorption of Al, Cd, Co, Cu, Mn, Ni and Zn from a single solution by the two lignocellulosic-based felts was examined using a batch mode. The parameters studied were initial metal concentration, adsorbent dosage, contact time, and pH...

## A Multidisciplinary Approach for the Assessment of Origin, Fate and Ecotoxicity of Metal(loid)s from Legacy Coal Mine Tailings

**Authors:** Gauthier-Manuel H, Radola D, Choulet F, Buatier M et al.

**Source:** TOXICS 9(7): 164, 2021, DOI 10.3390/toxics9070164

**Abstract:** Over the course of history, the development of human societies implied the exploitation of mineral resources which generated huge amounts of mining wastes leading to substantial environmental contamination by various metal(loid)s. This is especially the case of coal mine tailings which, subjected to weathering reactions, produce acid mine drainage (AMD), a recurring ecological issue related to current and past mining activities. In this study, we aimed to determine the origin, the fate and the ecotoxicity of metal(loid)s leached from a historical coal tailing heap to the Beuveroux river (Franche-Comte, France) using a combination of mineralogical, chemical and biological approaches...
# The Foraging Gene, a New Environmental Adaptation Player Involved in Xenobiotic Detoxification

**Authors:** Amichot M, Tares S

**Source:** INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 18(14): 7508, 2021, DOI 10.3390/ijerph18147508

**Abstract:** Foraging is vital for animals, especially for food. In Drosophila melanogaster, this behavior is controlled by the foraging gene (for) which encodes a cyclic guanosine monophosphate (cGMP)-dependent protein kinase (PKG). In wild populations of Drosophila, rover individuals that exhibit long foraging trails and sitter individuals that exhibit short ones coexist and are characterized by high and low levels of PKG activity, respectively. We, therefore, postulated that rover flies are more exposed to environmental stresses, including xenobiotics contamination, than sitter flies. We then tested whether these flies differed in their ability to cope with xenobiotics by exposing them to insecticides from different chemical families. We performed toxicological tests and measured the activity and expression levels of different classes of detoxification enzymes...

# Taking full advantage of modelling to better assess environmental risk due to xenobiotics-the all-in-one facility MOSAIC

**Authors:** Charles S, Ratier A, Baudrot V, Multari G et al...

**Source:** ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH Early Access, 2021, DOI 10.1007/s11356-021-15042-7

**Abstract:** In the European Union, more than 100,000 man-made chemical substances are

awaiting an environmental risk assessment (ERA). Simultaneously, ERA of these chemicals has now entered a new era requiring determination of risks for physiologically diverse species exposed to several chemicals, often in mixtures. Additionally, recent recommendations from regulatory bodies underline a crucial need for the use of mechanistic effect models, allowing assessments that are not only ecologically relevant, but also more integrative, consistent and efficient. At the individual level, toxicokinetic-toxicodynamic (TKTD) models are particularly encouraged for the regulatory assessment of pesticide-related risks on aquatic organisms. In this paper, we first briefly present a classical dose-response model to showcase the on-line MOSAIC tool, which offers all necessary services in a turnkey web platform, whatever the type of data analyzed...

# Quantification of the organophosphate flame retardant triphenylphosphate and its main metabolite in whole blood by liquid-liquid micro-extraction and liquid chromatography-tandem mass spectrometry

**Authors:** Giroud B, Bulete A, Spinner L, Deverchere J et al.

**Source:** MICROCHEMICAL JOURNAL 168: 106374, 2021, DOI 10.1016/j.microc.2021.106374

**Abstract:** This work proposes a rapid, simple and accurate analytical method for quantification of the organophosphate flame retardant triphenylphosphate (TPhP) and the biomarker diphenylphosphate (DPhP) in whole blood by a simple and effective sample preparation followed by liquid chromatography-tandem mass spectrometry (LC-MS/ MS) quantification. A liquid-liquid microextraction (mu LLE) from 250 µL of mouse whole blood was developed and
validated to quantify TPhP and DPhP. Nature of extraction solvent, grinding for cell lysis and purification step were investigated...

## Lack of impact of radiation on blood physiology biomarkers of Chernobyl tree frogs

**Authors:** Burraco P, Bonzom JM, Car C, Beaugelin-Seiller K et al.

**Source:** FRONTIERS IN ZOOLOGY 18(1): 33, 2021, DOI 10.1186/s12983-021-00416-x

**Abstract:** Background: Human actions have altered natural ecosystems worldwide. Among the many pollutants released to the environment, ionizing radiation can cause severe damage at different molecular and functional levels. The accident in the Chernobyl Nuclear Power Plant (1986) caused the largest release of ionizing radiation to the environment in human history. Here, we examined the impact of the current exposure to ionizing radiation on blood physiology biomarkers of adult males of the Eastern tree frog (Hyla orientalis) inhabiting within and outside the Chernobyl Exclusion Zone. We measured the levels of eight blood parameters (sodium, potassium, chloride, ionized calcium, total carbon dioxide, glucose, urea nitrogen, and anion gap), physiological markers of homeostasis, as well as of liver and kidney function...

## Identification of non-endocrine disrupting chemical characterization methods by screening of the literature using artificial intelligence and by database exploration

**Authors:** Zgheib E, Kim MJ, Jornod F, Bernal K, Tomkiewicz C et al.

**Source:** ENVIRONMENT INTERNATIONAL 154: 106574, 2021, DOI 10.1016/j.envint.2021.106574

**Abstract:** Background: Exposure to endocrine disrupting chemicals (EDCs) represents a critical public health threat. Several adverse health outcomes (e.g., cancers, metabolic and neurocognitive/neurodevelopmental disorders, infertility, immune diseases and allergies) are associated with exposure to EDCs. However, the regulatory tests that are currently employed in the EU to identify EDCs do not assess all of the endocrine pathways. Objective: Our objective was to explore the literature, guidelines and databases to identify relevant and reliable test methods which could be used for prioritization and regulatory pre-validation of EDCs in missing and urgent key areas. Methods: Abstracts of articles referenced in PubMed were automatically screened using an updated version of the AOP-helpFinder text mining approach...

## Single and mixed exposure to cadmium and mercury in *Drosophila melanogaster*: Molecular responses and impact on post-embryonic development

**Authors:** Frat L, Chertemps T, Pesce E, Bozzolan F et al.

**Source:** ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 220: 112377, 2021 DOI 10.1016/j.ecoenv.2021.112377

**Abstract:** Heavy metals, like many other chemical elements, are naturally present in the environment; however, the concentrations of these metals in various environmental matrices have increased through their intensive use in many human activities (such as industry, mining and agriculture). Among the heavy metals, cadmium (Cd) and mercury (Hg) induce a wide variety of defects in animals. While the effects of these heavy metals have been widely documented, a single exposure paradigm is
typically used. Few studies have focused on evaluating combined exposure to these metals. However, in the environment, animals are confronted with a plethora of substances simultaneously; thus, the presence and origin of such substances must be determined to reduce the sources of contamination. Using the model of the fruit fly Drosophila melanogaster, for which many tools are readily available, we investigated how different concentrations of Cd and Hg in single and combined exposures impact post-embryonic development...

## Risk of Anticoagulant Rodenticide Exposure for Mammals and Birds in Parc National des Pyrenees, France

**Authors:** Lestrade M, Vergne T, Guinat C, Berny P et al.

**Source:** JOURNAL OF WILDLIFE DISEASES 57(3): 637-642, 2021, DOI 10.7589/JWD-D-20-00125

**Abstract:** The extensive use of anticoagulant rodenticides (ARs) to control rodent populations poses intoxication risks for wildlife: persistence of ARs in rodents can cause secondary exposure and poisoning of predators or scavengers. We investigated risk factors for wildlife exposure to ARs in the Parc National des Pyrenees (PNP), France, using a multivariable logistic regression analysis. A total of 157 liver samples were collected from carcasses of 10 mammal and three bird species found in the PNP between 2010 and 2018 and screened for presence of AR residues...

**Source:** JOURNAL OF HAZARDOUS MATERIALS 407: 124801, 2021, DOI 10.1016/j.jhazmat.2020.124801

**Abstract:** Micropollutants such as pharmaceuticals and pesticides are still found in treated municipal effluent and are discharged into the natural environment. Natural direct photodegradation may be one pathway for removing these micropollutants in treatment processes such as free-water surface constructed wetlands (CW). This work was set out to evaluate the half-life ($t(1/2)$) of direct photodegradation of 36 micropollutants under controlled conditions of light exposure close to solar radiation...

## Introduction: Beyond the Production of Ignorance: The Pervasiveness of Industry Influence through the Tools of Chemical Regulation

**Abstract:** Research on the influence of industry on chemical regulation has mostly been conducted within the framework of the production of ignorance. This special issue extends this research by looking at how industry asserts its interests-- not just in the scientific sphere but also at other stages of policy-making and regulatory process-- with a specific focus on the types of tools or instruments industry has used. Bringing together sociologists and historians specialized in Science
and Technology Studies (STS), the articles of the special issue study the arenas in which instruments and practical guidelines for public policy are negotiated or used. The aim is to observe the devices in the making or in action, from the selection of actors to the production of thresholds, criteria, and other technical regulations...

## Biochar and activated carbons preparation from invasive algae Sargassum spp. for Chlordecone availability reduction in contaminated soils

**Authors:** Ranguin R, Delannoy M, Yacou C, Jean-Marius C et al.

**Source:** JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING 9(4): 105280, 2021, DOI 10.1016/j.jece.2021.105280

**Abstract:** This work aims to valorize an invasive brown macroalga (Sargassum spp. consisting of two species Sargassum fluitans and Sargassum natans) by producing biochars (BCs) and activated carbons (ACs). Its abundant and frequent occurrence along the Caribbean coastlines, Florida, Gulf of Mexico during the last past nine years, have triggered human health concerns and have negatively impacted local economy, ecology and the environment. In this paper, BCs and ACs were developed to assess the reduction of chlordecone (CLD) environmental availability in artificial and tropical contaminated soils. Such innovative approach was proposed to limit CLD bio-availability to fauna and outdoor reared-animals...

Reported concentrations were summarized using statistical parameters, then spatialized and finally classified in contamination classes according to local legislation....

## Transfer of sulfidized silver from silver nanoparticles, in sewage sludge, to plants and primary consumers in agricultural soil environment

**Authors:** Courtois P, de Vaufleury A, Grosser A, Lors C et al.

**Source:** SCIENCE OF THE TOTAL ENVIRONMENT 777: 145900, 2021, DOI 10.1016/j.scitotenv.2021.145900

**Abstract:** Consumer products containing silver nanoparticles (AgNPs) release silver (Ag) to the environment, particularly wastewater. Sewage sludge (SS), which contains numerous contaminants including Ag, is recycled by spreading on agricultural land. Although slight impacts and bioaccumulation of Ag sulfide (Ag2S, the main species found in SS) in terrestrial
organisms have been demonstrated, possible trophic transfer into plants and subsequently animal species has not been examined. Accordingly, the present study experimentally measured the transfer of Ag from AgNPs and sulfidized Ag into plants and primary consumers and compared their bioavailability...

# Potential of preventive bioremediation to reduce environmental contamination by pesticides in an agricultural context: A case study with the herbicide 2,4-D

**Authors:** Carles L, Martin-Laurent F, Devers M, Spor A et al.

**Source:** JOURNAL OF HAZARDOUS MATERIALS 416: 125740, 2021, DOI 10.1016/j.jhazmat.2021.125740

**Abstract:** One of the major problems with pesticides is linked to the non-negligible proportion of the sprayed active ingredient that does not reach its intended target and contaminates environmental compartments. Here, we have implemented and provided new insights to the preventive bioremediation process based on the simultaneous application of the pesticide with pesticide-degrading microorganisms to reduce the risk of leaching into the environment. This study pioneers such a practice, in an actual farming context. The 2,4-dichlorophenoxyacetic acid herbicide (2,4-D) and one of its bacterial mineralizing-strains (Cupriavidus necator JMP134) were used as models. The 2,4-D biodegradation was studied in soil microcosms planted with sensitive (mustard) and insensitive (wheat) plants...

# Efficiency of dihydroxamic and trihydroxamic siderochelates to extract uranium and plutonium from contaminated soils

**Authors:** Fevrier L, Coppin F, Pierrisnard S, Bourdillon M et al.

**Source:** JOURNAL OF ENVIRONMENTAL RADIOACTIVITY 235: 106645, 2021, DOI 10.1016/j.jenvrad.2021.106645

**Abstract:** Actinide-based mineral phases occurring in contaminated soils can be solubilized by organic chelators excreted by plants, such as citrate. Herein, the efficiency of citrate towards U and Pu extraction is compared to that of siderophores, whose primary function is the acquisition of iron(III) as an essential nutrient and growth factor for many soil microorganisms. To that end, we selected desferrioxamine B (DFB) as an emblematic bacterial trishydroxamic siderophore and a synthetic analog, abbreviated (LCy,Pr)H2, of the tetradentate rhodotorulic acid (RA) produced by yeasts.

**Abstract:** Several sustainable development goals cannot be achieved without implementing a new generation of environmental measures to better preserve or restore biodiversity and ecosystem services. However, understanding and addressing biodiversity loss and ecosystem degradation is a challenging problem that is not solvable without integrating the best and latest science. It is crucial to enhance the legibility of this knowledge for decision-makers and policymakers following good-practice standards of scientific assessment. This is the main objective of collective scientific assessments (CSAs), as carried out by the French National Research Institute for Agriculture, Food and the Environment (INRAE) since the early 2000s following a documented procedure to inform public policy and foster public debate on complex interdisciplinary issues...

**Abstract:** Simple Summary The moth larvae are among the most damaging pest species on crops worldwide. In this review, we focus on the genus Spodoptera, which can feed on many crops such as rice, cotton or corn. The massive use of insecticides to control these insects has led to the development of resistance. Here, we aim to compare the resistance mechanisms of four species (Spodoptera exigua, Spodoptera frugiperda, Spodoptera littoralis and Spodoptera litura) and highlight the role of enzymes and transporters in resistance to help us understand the molecular basis of their origin. The genus Spodoptera (Lepidoptera: Noctuidae) includes species that are among the most important crop

pests in the world. These polyphagous species are able to feed on many plants, including corn, rice and cotton. In addition to their ability to adapt to toxic compounds produced by plants, they have developed resistance to the chemical insecticides used for their control...

## Evaluation of DGT and DGT-PROFS modeling approach to estimate desorption kinetics of Cs in soils

**Abstract:** The aim of this paper is to assess the suitability of DGT to extract kinetic rates of desorption of cesium (Cs) from soils. For this purpose, laboratory experiments with a natural soil spiked with Cs were carried out under three different contamination conditions, reflecting either an increase in Cs contamination level or an ageing of the contamination within the soil. The experimental results, i.e. the Cs accumulation kinetics onto DGT probes were interpreted by the DGT-PROFS model. The latter calculates the partitioning of Cs between two particulate pools, describing weak and strong interactions respectively, as well as kinetic rates describing exchange reactions...
