A guerra civil na Síria: breve olhar sobre Aleppo a partir de Hannah Arendt
Authors: Arruda Júnior Moacyr Gomes de , Silva João Alberto Mendonça , Maciel Josemar de Campos
Published: April 2021

Este artigo busca olhar a recente Guerra Civil Síria, em especial as situações ocorridas na cidade de Aleppo, em diálogo com a óptica de Hannah Arendt. A partir de literatura especializada, aponta-se para possíveis contribuições do pensamento arendtiano para a reflexão acerca da situação vivenciada pelo povo sírio. O trabalho se organiza em três momentos: 1. Exposição da Guerra Civil Síria em Aleppo; 2. Apresentação e exploração dos conceitos arendtianos que podem lançar luz sobre as situações; e 3. Retorno aos conceitos de Arendt refletidos à luz da Guerra Civil Síria, sobretudo em relação à dignidade humana e ao extermínio. Conclui-se que retomar tais conceitos facilita o enquadramento da reflexão sobre o ser humano como sujeito de direitos devido ao fato de sua existência, razão ignorada pelos que fazem a guerra ao aniquilarem a dignidade, ora transformando os massacres em dados estatísticos, ora ignorando completamente todas as mortes e destruições contínuas.

Compétitivité et emplois à la production dans les secteurs bovins français
Authors: CHATELLIER Vincent , PERROT Christophe , BEGUIN Emmanuel , MORAINE Marc , VEYSSET Patrick
Published: April 2021

Dans un contexte caractérisé par l’existence de difficultés d’ordre économique, social et environnemental, cette communication a pour ambition de présenter, de façon synthétique, un état des lieux chiffré des secteurs bovins (lait et viande) français. Elle s’appuie pour ce faire sur l’utilisation de différentes sources d’informations disponibles, dont les données des douanes, du Réseau d’Information Comptable Agricole et de la Mutualité Sociale Agricole. Les deux premières parties abordent la question de la dynamique des marchés en produits laitiers et en viande bovine (production, consommation et échanges) en distinguant successivement le marché extérieur (compétitivité externe au cours de la période 2000-2019) puis le marché intérieur (adéquation entre l’offre et la demande, utilisateurs finaux des produits) ; une analyse portant sur la différenciation de l’offre permet également d’aborder la place des différents signes de qualité et de nouvelles formes de démarcations commerciales s’appuyant sur une référence au territoire. Les deux dernières parties traitent de l’évolution de l’organisation de la production, en s’intéressant d’abord à la compétitivité des exploitations françaises sur longue période (1990-2018), puis aux emplois dans les exploitations (renouvellement des générations ou plutôt des actifs, transformation des formes d’installation).
The Paradox of Employee–Volunteer Interchangeability in a Supported Social Enterprise
Authors: Akingbola Kunle , Phaetthayanan Suwimon
Published: April 2021

This research examines the paradox of employee–volunteer interchangeability as a core resource in a nonprofit social enterprise organization. Specifically, the research investigates a) how the human and social capital derived from employee–volunteer interchangeability drives strategic intent, and b) how challenges associated with employee–volunteer interchangeability hinder strategic intent. The research provides insight into how employees and volunteers value outcomes that are dependent on the inherent paradox of interchangeability. The findings reveal that while employee– volunteer interchangeability can be a core resource, a social value, and a driver of competitive advantage, it can also hinder organizational strategies and growth—especially for nonprofit social enterprise organizations.

Published: April 2021

We attempted to establish an objective method to accurately evaluate the motility of bull sperm and examined the effects of media for sperm suspensions and frame rates on data of computer-assisted sperm motility analysis (CASA). Sperm incubated in Brackett and Oliphant medium (BO) more clearly showed hyperactivation-like motility than those in synthetic oviductal fluid. Sperm images captured at 150 frames per second (fps) showed a trajectory that was closer to the real pathway than those at other frame rates (30, 50, and 75 fps). We then examined the characteristics of sex-sorted and non-sorted semen using a cluster analysis followed by a discriminant analysis of sperm motility in BO at 150 fps. The results indicated that sex-sorted semen contained sperm with hyperactivation-like motility as the main subpopulation immediately after thawing and this subpopulation decreased after 2-h incubation. The main subpopulation in non-sorted semen had progressive motility that was maintained during incubation. In conclusion, usage of BO for sperm suspensions and capturing sperm motility at 150 fps by CASA were appropriate for evaluating bovine sperm motility. A discriminant analysis using data from a cluster analysis of motile sperm has the ability to accurately describe differences in the structures of sperm motility subpopulations.
Leptinergic Regulation of Vertebrate Communication Signals
Authors: Nourbakhsh-Rey Mehrnoush , Markham Michael
Published: April 2021

Animal communication signals are regulated by multiple hormonal axes that ensure appropriate signal targeting, timing, and information content. The regulatory roles of steroid hormones and many peptide hormones are well understood and documented across a wide range of vertebrate taxa. Two recent studies have reported a novel function for leptin, a peptide hormone central to energy balance regulation: regulating communication signals of weakly electric fish and singing mice. With only limited evidence available at this time, a key question is just how widespread leptinergic regulation of communication signals is within and across taxa. A second important question is what features of communication signals are subject to leptinergic regulation. Here we consider the functional significance of leptinergic regulation of animal communication signals in the context of both direct and indirect signal metabolic costs. Direct costs arise from metabolic investment in signal production, while indirect costs arise from the predation and social conflict consequences of the signal’s information content. We propose a preliminary conceptual framework for predicting which species will exhibit leptinergic regulation of their communication signals and which signal features leptin will regulate. This framework suggests a number of directly testable predictions within and across taxa. Accounting for additional factors such as life history and reproductive strategies will likely require modification or elaboration of this model.

Authors: Belmudes Dalton , David Fernanda S. , Gonçalves Fernando F. H. , Valenti Wagner C.
Published: April 2021

Protected areas have been used worldwide to conserve natural resources. Nevertheless, economic activities to provide income for communities living inside and surrounding conservation areas remain an issue. This study aimed to assess the sustainability of a Deuterodon iguape hatchery, placed inside an Atlantic Rainforest Park, to leverage this small native fish's grow-out farming, affording income and food security for local families. We have used a set of indicators of economic, social, and environmental sustainability. The initial investment is about US$ 40,000, which returned in ~2 years. The internal rate of return is close to 50%, including the externality costs, which is attractive for public and private investments. The hatchery generated few direct jobs, but the workforce can be recruited in the community, and hatchery can enable the establishment of several small grow-out farms, leveraging the development of indirect jobs and self-employments. The system had a low environmental impact, showing minor release of pollutants, low risk for biodiversity, and absorption of 18 g of CO2 equivalent per thousand post-larvae produced, contributing to the struggle against climate change. Therefore, D. iguape hatchery demonstrates the potential of combining biodiversity conservation and income generation, meeting the Sustainable Development Goals of Agenda 2030.

Authors: Hanfi Mohamed Y. , Seleznev Andrian A. , Yarmoshenko Ilia
Published: April 2021

Study of gross alpha (GA) and gross beta (GB) activity in road and surface deposited sediments were performed in various geographical areas in three Russian cities. To perform radiation measurements, new methods were applied which allow dealing with low mass and low volume dust size (2-100μm) samples obtained after the size fractionation procedure. The 2-10 μm fraction size has the highest gross beta activity concentration (GB)– 1.32Bq/g in Nizhny Novgorod (NN) and Rostov-On-Don (RND) while the 50-100 μm fraction size in Ekaterinburg. This is maybe associated with the subsistence of radionuclides that conveyed through natural processes and anthropogenic applications. The highest gross alpha activity concentration (GA) in fraction sizes was found in Rostov-on-Don city within the 50-100 μm– 0.22Bq/g. The fraction size 50-100 μmhas a higher gross alpha activity concentration than 2-10 and 10-50 μmfraction sizes due to natural partitioning of the main minerals constituting the urban surface deposited sediment (USDS). The geochemical processes that occur during the formation and transportation of USDS are reflected in the observed dependencies.Developed experimental methods of radiation measurements allowed to the extent the methodological base of urban geochemical studies.

A new approach to fabricate TiNi surfaces combining the advantages of both monolithic and porous materials for implants is used in this work. New materials were obtained by depositing a porous TiNi powder onto monolithic TiNi plates followed by sintering at 1200°C. Then, further modification of the material surface with a high-current-pulsed electron beam (HCPEB) was carried out. Three materials obtained (one after sintering and two after subsequent beam treatment by 20 and 30 pulses, respectively) were studied by XRD, SEM, EDX, EIS methods, profilometry and OCP measurements. Structural and compositional changes caused by HCPEB treatment were investigated. Surface properties of the samples during their storage in saline for 10 days were studied and a model experiment with cell growth (MCF-7) was carried out for the sample unmodified with electron beam to detect cell appearance on different surface locations.

Based on the cloud platform of Google Earth Engine (GEE), this study selected Landsat 5/8 and Sentinel-2 remote sensing images and used Support Vector Machine (SVM) classification method to classify the 35 years of intertidal salt marshes in China, and verified the classification results in combination with field survey. Finally, combining with various driving factors, the reasons and laws affecting the changes of salt marshes species and area were discussed and analyzed. The main results of the study are as follows:The main types of salt marshes plants in China include Phragmites australis, Spartina alterniflora, Suaeda salsa, Scirpus mariquete, Tamarix chinensis, Cyperus malaccensis and Sesuvium portulacastrum.
The results salt marshes classification indicated that 166999.32 ha in 1985, 172893.87 ha in 1990, 174952.29 ha in 1995, 125567.51 ha in 2000, 93257.97 ha in 2005, 102539.04 ha in 2010, 96302.92 ha in 2015, and 115722.75 ha in 2019. The main driving factors of salt marsh change from 1985 to 2015 are reclamation, mudflat aquaculture, climate change, coastal zone erosion, invasion of alien species, and natural competition and succession among salt marshes species. The results can be used to quantitatively analyze the salt marshes carbon storage in space and time, and provide data support for the protection of salt marsh wetlands, the restoration of ecological functions and the implementation of "carbon neutral".
Influence of Chinese National Centralized Drug Procurement on the Price of Policy-Related Drugs: An Interrupted Time Series Analysis
Authors: Wang Ni , Yang Ying , Xu Luxinyi , Mao Zongfu , Cui Dan
Published: April 2021

In 2019, Chinese government implemented the first round of National Centralized Drug Procurement (NCDP) pilot (so-called "4+7" policy) in mainland China, achieved a prominent price reduction of 52% on average for 25 bidding winning products. Under cross-price elasticity theory, the price behavior of pharmaceutical enterprises for policy-related drugs might change. This study used drug purchasing data from the Centralized Drug Procurement Survey in Shenzhen 2019, and applied single-group Interruption Time Series (ITS) design to examine the impact of "4+7" policy on the drug price index (DPI) of policy-related drugs. The ITS analysis showed that the DPI of winning (-0.183 per month, p<0.0001) and non-winning (-0.034 per month, p=0.046) products significantly decreased after the implementation of "4+7" policy. No significant difference was found for the immediate change of DPI for alternative drugs (p=0.537), while a significant decrease in change trend was detected in the post-"4+7" policy period (-0.003 per month, p=0.014). The DPI of the overall policy-related drugs significantly decreased (-0.261 per month, p<0.0001) after "4+7" policy. These findings indicate that the price behavior of pharmaceutical enterprises changed under NCDP policy, while the price linkage effect is still limited. It is necessary to further expand the scope of centralized purchased drugs and strengthen the monitoring of related drugs regarding price change and consumption structure.
IDEA OF ECOSTRUCTURE IN CONTEMPORARY ARCHITECTURE OF OSLO
Authors:   Wroclaw University of Science and Technology Faculty of Architecture Department of Architectural and Construction Design, Cisek Ewa
Published: April 2021

The revitalization actions carried out in recent years within the urban tissue of Oslo made it possible to generate architectural layouts of a new character known as eco-structures. They are created both in the wharf zones of the city and accompanying natural and artificially formed promontories (Fjordbyen enterprise) as well as in its very centre (Grünerløkke district). These are old closed port and post-industrial areas now transformed into new layouts with residential, service, culture-creating and recreation functions. Frequently shaped on the border of two environments, i.e. urban and water as well as urban and park ones, they create a new quality of architecture making a dialogue with the natural environment and the local ecosystem.
INTUITION AND DEDUCTION IN THE PROCESS OF EXPLAINING THE CORRECTNESS OF PROOF IN ARCHITECTURAL DIAGRAMS
Authors:   Andrzej Frycz Modrzewski Krakow University Faculty of Architecture and Fine Arts, Maryńczuk Paweł
Published: April 2021

Creating diagrams is an occasion for a sophisticated analysis of notions and exploring their meaning. It is also a form of direct contact with psychological phenomena and juxtaposing intuition and deduction as sources of cognition. Analysis of the development of philosophical stances can present the process of a departure from the classical view that holds that this argumentation can have a purely formal character (while the role of intuition is significantly reduced). The by-product shall be an explanation of often encountered simplifications associated with understanding both positions associated with their extreme versions: the intuitive relict or the version of formalism that produces an impression of being a sterile and even absurd argument. I argue in favour of the utility of both positions, as they can present interesting aspects of certain problems in architectural proofs at different stages of design, and used to distinguish different diagrams.
TEARING THE SPACE APART. RESPONSIBLE PARTICIPATION OR SELF-SERVING PARTICIPATION
Authors:   Zachodniopomorski Uniwersytet Technologiczny w Szczecinie Wydział Architektury Katedra Projektowania Architektonicznego, Barełkowski Robert
Published: April 2021

Participation in spatial planning has specific origins rooted in the ideology that in the past was responsible for inhuman actions and large-scale social manipulations. This article is an account on participation, written in the context of over twenty years of experience in actively introducing participatory techniques into various planning procedures. The original assumptions about making spatial planning a matter of importance to local communities had to collide with the reality determined both by the authorities and by individual and collective interests. The attempt to reorient the paradigm of social participation is aimed at preserving many of its positive features.
STREET ANTHROPOLOGY – A CULTURE OF MOBILITY
Authors:   West Pomeranian University of Technology in Szczecin Faculty of Architecture Department of Architectural Design, Czyński Marek
Published: April 2021

The street anthropology is identical with the anthropology of urban life. In the past, a street was a place to socialize and, on equal footing with its architecture, it was part of the cultural identity of its inhabitants. The street reflects residents’ social, cultural and economic capital. Over time, mobility and communication accessibility have dominated the urban spatial policy. The contemporary street has become a "space of flows". The restoration of its original role requires a more balanced approach to cultural factors that determine the quality of life in a city. The article discusses characteristic features that determine patterns of mobility in modern streets.

Chemoattractants: Their essentiality and efficacy in shrimp aquaculture
Authors: Jannathulla R. , Sravanthi O. , Imran Khan H. , Syed Moomeen H. , Gomathi A. , Syama Dayal J.
Published: April 2021

Aquaculture serves as a sustainable source of good quality wholesome food and major input is feed. In recent years, considerable quantities of plant sources have been attempted for inclusion in shrimp feed, due to high demand and high cost of fishmeal. Plant-based ingredients are in general poor in attractability and palatability to aquatic species compared to marine sources. It is desirable to develop an economical and nutritious feed that is attractive and palatable for ensuring reduction of feed wastage. Chemoattractants nowadays are unavoidable in commercial shrimp feeds and are included either individually or in combination. The present review revealed that the various marine sources, in particular krill meal would be more effective for aquatic species, compared to those derived from vegetable origin and chemical compounds. In addition to acting as a feed attractant, marine sources serve as a potential fishmeal substitute due to their rich nutritional composition. However, certain biogenic amines present in these marine-based ingredients need to be examined before their use, since these amines when present in high concentrations reduces feed intake by producing undesirable odour. Use of a combination of chemoattractants would give a better effect, rather than using them individually and compounds from plant origin have limited beneficial effects. The present review concludes that incorporation of chemoattractants would be beneficial in formulation of enriched and economical feeds with better attractability and palatability. The selection of suitable attractant and their supplementation at correct proportion is significantly more important to avoid undesirable effects in cultured shrimp. Further field-based research is needed to predict the actual effects of chemoattractants on farmed shrimp and to provide a sustainable base for the expansion of shrimp aquaculture sector, by reducing feed wastage.
3D Numerical Model for Hydraulic Fracture Propagation in Tight Ductile Reservoirs, Considering Multiple Influencing Factors via the Entropy Weight Method
Authors: Ju Yang , Wu Guangjie , Wang Yongliang , Liu Peng , Yang Yongming
Published: April 2021

In this paper, we introduce the entropy weight method (EWM) to establish a comprehensive evaluation model able to quantify the brittleness of reservoir rocks. Based on the evaluation model and using the adaptive finite element-discrete element (FE-DE) method, a 3D model is established to simulate and compare the propagation behavior of hydraulic fractures in different brittle and ductile reservoirs. A failure criterion combining the Mohr-Coulomb strength criterion and the Rankine tensile criterion is used to characterize the softening and yielding behavior of the fracture tip and the shear plastic failure behavior away from the crack tip during the propagation of a fracture. To understand the effects of rock brittleness and ductility on hydraulic fracture propagation more intuitively, two groups of ideal cases with a single failure mode are designed, and the fracture propagation characteristics are compared and analyzed. By combining natural rock core scenarios with single failure mode cases, a comprehensive evaluation index BIf for reservoir brittleness and ductility is constructed. The simulation experiment results indicate that fractures in brittle reservoirs tended to form a complex network. With enhanced ductility, the yielding and softening of reservoirs hamper fracture propagation, leading to the formation of a simple network, smaller fracture area (FA), larger fracture volume, and the need for higher initiation pressure. The comprehensive index BIf can be used to define brittleness or ductility as the dominant factor of fracturing behavior. That is, 0 < BIf ≤ 0.46 indicates that the reservoir has enhanced ductility and ductile fracturing prevails; 0.72 < BIf < 1 indicates that the reservoir has enhanced brittleness and brittle fracturing prevails; and 0.46 < BIf ≤ 0.72 means a transition from brittle to ductile fracturing. Based on fitting analysis results, the relationship between the calculated FAr and BIf is constructed to quantify the influence of reservoir brittleness and ductility on fracturing. The study provides new perspectives for designing, predicting, and optimizing the fracturing stimulation of tight reservoirs with various brittleness and ductility.

Background Idiopathic pulmonary fibrosis (IPF) is a relentlessly progressive and fatal fibrotic lung disease all over the world, and specific pathogenesis is still not well understood. DNA methylation is an essential epigenetic mechanism, which likely contributes to the progress of IPF. The purpose of this study is to identify aberrantly methylated differentially expressed genes (DEGs) in IPF and to explore the underlying mechanisms of IPF by using integrated bioinformatics analysis.Methods Gene expression profiles and gene methylation profiles were downloaded and analyzed to identify the aberrantly methylated‐differentially expressed genes. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Search Tool for the Retrieval of Interacting Genes Database (STRING), and Gene set enrichment analysis (GSEA) were used to evaluate the function of DEGs. RT-PCR was used to verify the mRNA levels of DEGs in mice with pulmonary fibrosis.Results By analyzing the differentially expressed genes of the three IPF expression profiles, and taking the intersection, we got 143 co-upregulated genes and 104 co-downregulated genes; GO and KEGG pathway analysis of the DEGs suggested these genes involved in the extracellular matrix organization, multicellular organismal homeostasis. Combining the sequencing data of two IPF methylation chips, we have identified genes that may be regulated by methylation in IPF. Finally, we obtained the mRNA expression of DEGs using a mouse model of pulmonary fibrosis.Conclusions Through integrated analysis and experimental verification, we found a series of biomarkers that were regulated by methylation should be potential therapeutic targets for IPF.

Background-Ethnic minorities account for 34% of critically ill COVID-19 patients despite constituting 14% of the UK population. Internationally, researchers have called for studies to understand deterioration risk factors to inform clinical risk tool development. Methods-Multi-centre cohort study of hospitalised COVID-19 patients (n=3671) exploring determinants of health, including Index of Multiple Deprivation (IMD) sub-indices, as risk factors for presentation, deterioration and mortality by ethnicity. Receiver operator characteristics were plotted for CURB65 and ISARIC4C by ethnicity and area under the curve (AUC) calculated.Results-Ethnic minorities were admitted with higher Charlson Comorbidity Scores than age, sex and deprivation matched controls and from the highest IMD sub-indices of at least one deprivation form: Indoor Living Environment(LE), Outdoor LE, Adult Skills and Wider Barriers to Housing and Services. Admission from the highest sub-indices of these deprivation forms was associated with multilobar pneumonia on presentation and ITU admission. AUC did not exceed 0.7 for CURB65 or ISARIC4C among any ethnicity except ISARIC4C among Indian patients 0.83 (0.73-0.93). Ethnic minorities presenting with pneumonia and low CURB65(0-1) had higher mortality than Caucasians (22.6% vs.9.4%; p<0.001); Africans were at highest risk (38.5%; p=0.006), followed by Caribbean (26.7%; p=0.008), Indian (23.1%; p=0.007) and Pakistani (21.2%; p=0.004).Conclusions-Ethnic minorities exhibit higher multimorbidity despite younger age structures and disproportionate exposure to unscored risk factors: obesity and deprivation. Household overcrowding, air pollution, housing quality and adult skills deprivation are associated with multi-lobar pneumonia on presentation and ITU admission which are mortality risk factors. Risk tools need to reflect risks predominantly affecting ethnic minorities.

Background: Diabetes Mellitus (DM) is a chronic, progressive disease characterized by elevated levels of blood glucose. Despite the fact that most international association/organization gave attention toward diabetes control and prevention by healthy professional, still diabetes and its complication such as cardio vascular, blood vessels, eyes, kidneys and nerves become a major cause of premature death and disability across the world. The overall aim of this study is assessing fasting blood sugar variation over time and its determinant among diabetic patients. Methods: Data were obtained from Adama Hospital Medical College diabetic patients who have been active in the follow-up treatment from September 1, 2018 to August 30, 2019. The data consists of basic demographic and clinical characteristics of 312 DM patients were selected using simple random sampling techniques and of whom 177 were males and the rest 135 were females. The linear mixed effect model for longitudinal data analysis was used by taking the correlation between Fasting Blood Sugar (FBS) level of patients into account. Linear mixed model, random intercept and slope models were used for feting the data. Results: The results from the linear mixed model with unstructured co-variance structure showed that for one-month change in time decreases log FBS level by 0.0111267 mg/dl. While a unit increase in Body Mass Index (BMI) of a patient on treatment, the log FBS level was increased by 0.0434 mg/dl. Similarly, a unit increase in Diastolic Blood Pressure (DBP), the log FBS level was increased by 0.0004749 mg/dl. Being tertiary and secondary level of education decreases logFBS level by 0.0058844 and 0.0055161 respectively compared with patients with no education.Conclusion: Age, Educational status, Dietary type, Drug type, History of hypertension, BMI, DBP, Time, interaction effect of Age, history of hypertension, Dietary type, other comorbidity at baseline with time were the significant determinant for the change in mean FBS level of the diabetes patients over time. Based on the findings of our study and WHO recommendation, maintaining of healthy body weight, by taking healthy diet along with lower blood glucose level is essential to control blood sugar in body and to prevent long term complication.
When positive is negative: The moderating role of DT on the relationship between micro-daily events and counterproductive work behavior

The workplace is a context, in which, individuals experience diverse types of micro daily events. Taking into account the personality traits, emotions vary, as does the perception of micro daily events. This study examined the three dimensions of the dark triad personality (machiavelism, psychopathy, and narcissism) as moderators of the relationship between micro-daily events, positive and negative, and counterproductive work-related behaviors. To achieve this goal, 205 working adults took part in this study. The results showed that: (1) daily micro-events predicted CWB’s, in particular, when the ratio of daily micro-events was positive, the CWB’s decreased; (2) the dark triad moderated the relation between micro daily-events and CWB’s, such that CWB’s decreased as the ratio of daily micro-events increased for individuals with high and moderate DT levels. Such results proved to be fundamental for a better understanding of the behavior of employees in organizations, as well as the impact of daily events in the organizational environment. The implications for theory and practice were discussed.

Face masks have been widely employed as a personal protective measure during the COVID-19 pandemic. However, concerns remain that masks create a false sense of security that reduces adherence to other public health measures, including social distancing. This paper tested whether mask-wearing was negatively associated with social distancing compliance. In two studies, we combined video-observational records of public mask-wearing in two Dutch cities with a natural-experimental approach to evaluate the effect of an area-based mask mandate. We found no observational evidence of an association between mask-wearing and social distancing, but found a positive link between crowding and social distancing violations. Our natural-experimental analysis showed that an area-based mask mandate did not significantly affect social distancing or crowding levels. Our results alleviate the concern that mask use reduces social distancing compliance or increases crowding levels. On the other hand, crowding reduction may be a viable strategy to mitigate social distancing violations.

Risk and source of heavy metal(loid)s (As, Cu, Cr, Pb, Mn, Ni, V, and Zn) were determined in the surrounding farmland soil of a zinc smelter in the water source area of the Mid–route of South–North Water Transfer Project of China to explore the impact of smelting activity on local environment. The heavy metal(loid)s contents were analyzed by X–ray fluorescence spectrometry and their pollution levels and ecological risks were assessed by geoaccumulation index, Nemerow synthetic pollution index and potential ecological risk index. The possible sources of the heavy metals(loid)s were identified by multivariate statistical analysis methods. The mean contents of the heavy metal(loid)s in the farmland soil were above the local soil background values except Mn. The contents of As, Cu, Pb, Zn, and Ni in the downwind direction soil decreased with the distance increasing between the sampling site and the zinc smelter. The investigated soils were moderately to seriously polluted by heavy metal(loid)s and the heavy metal(loid)s presented moderately ecological risk as a whole. As, Cu, Pb, and Zn mainly originated from zinc smelting activities. Cr, Mn, and V primarily derived from natural source. Ni mainly came from zinc smelting activities, partly from natural source. The zinc–smelting activity influenced the heavy metal(loid)s content, particularly Zn and Pb, in the surrounding farmland soil. The local government should strengthen the cooperative monitoring of heavy metal(loid)s in farmland and agricultural products, as well as pollutant emission monitoring and control.
