Arsenic Occurrence and Cycling in the Aquatic Environment: A Comparison between Freshwater and Seawater
Authors: Wang Ningxin , Ye Zijun , Huang Liping , Zhang Chushu , Guo Yunxue , Zhang Wei
Published: January 2023

Owing to the toxicity and adverse effects of arsenic on human health, its levels in aquatic environments are among the most serious threats to humans globally. To improve our understanding of its occurrence and cycling in aquatic environments, herein we review the concentration, speciation, and distribution of arsenic in freshwater, seawater, and sediments. Many natural processes, such as rock weathering and geothermal activities, contribute to the background arsenic concentrations in the natural environment, whereas metal mining and smelting are anthropogenic sources of arsenic in the water. The high solubility and mobility of arsenic in aquatic environments affects its global cycling. Furthermore, the biological processes in the aquatic environment are discussed, especially the possible microbe-mediated reactions of arsenic in sediments. In addition, various environmental factors, such as redox conditions, pH, and salinity, which influence the transformation of arsenic species, are summarized. Finally, the differences between freshwater and seawater with reference to the concentration as well as speciation and distribution patterns of arsenic are addressed. This review provides deep insights into arsenic occurrence and cycling between freshwater and seawater aquatic environments, which can more accurately distinguish the risks of arsenic in different water environments, and provides theoretical guidance for the prevention and control of arsenic risks.

Published: January 2023

Freshwater gastropods play key roles in shallow aquatic ecosystems, with a central position in the periphyton–gastropod–fish trophic pathway, as they feed on periphyton and are preyed on by animals of higher trophic levels. Thus, it is of great interest to explore how climate change impacts the gastropod community and the trophic cascading effects on periphyton. Here, we constructed a simplified, shallow lake food web in 24 large mesocosm tanks to simulate warming (+4.5 °C) on the population responses of two common snails (Bellamya aeruginosa and Radix swinhoei) in two different systems (without/with common carp Cyprinus carpio) over 200 days. We found that warming lowered the biomass and density of R. swinhoei by 16.8% and 41.6%, respectively, and accelerated the average time of density peak of R. swinhoei by 21.5 days in the common carp-absent system. The density of B. aeruginosa in the warming with common carp group was lowered by 79.8% more than in the warming group without common carp. The averaged biomass and density of R. swinhoei in the fish-present system significantly lowered by 64.4% and 92.5%, respectively, compared to the fish-absent system. Cascading effects were also observed, as the snail communities declined under warming, that is, the grazing pressure on periphyton was less, resulting in its higher biomass. In conclusion, in the fish-absent system, warming decreased the biomass and density of the R. swinhoei, and in both snail populations, the biomass and density were much higher than those in the fish-present system. Due to the different phenology of snail species and species-specific predation, future stronger predation in a continuous warming condition might undermine the diversity of the gastropods, thereby changing food web structures in shallow freshwater ecosystems.

Published: January 2023

The paper presents the results of physicochemical analyses of spring waters in the Postomia River valley (Northwest Poland). Multivariate statistical methods, i.e., cluster analysis (CA) and principal component analysis (PCA) were used to assess the spatial distribution of similarities and differences in the concentrations of individual elements. Concentrations of macro elements (MEs), trace elements (TEs) and rare-earth elements (REEs) were analysed concerning the spring’s typology, land use structure and the distance from roads. The results showed that the springs waters are of the Ca2+-HCO3− and Ca2+-HCO3−-SO42− types, medium hardness and low mineralisation. The study revealed differences between valley springs and scarp-foot springs in terms of electrical conductivity and concentrations of F−, SO42−, NO3−, Mg2+, Ba, Zn, and U. Greater variability was observed between the physical and chemical conditions of the spring waters due to their location in terms of land use. Springs located in agricultural areas had lower pH values than those in other areas, and higher NO3− concentrations. The pH values and concentrations of Fe, Mo, Rb, and Th in urban areas were higher than in agricultural areas. Moreover, the concentrations of F−, Cl−, K+, Na+, Mo, Sb, Se, and Sr were higher in urban areas than in forested areas. The study shows that only HCO3− values and SO42− concentrations were related to the distance from the road network. The concentrations of Cl−, SO42−, and K+ were higher in the waters of springs located more than 50 m from the road network. The Ca and PCA analysis did not permit the identification of a single dominant origin of pollutants, suggesting an interaction of different types of pollution sources.

Published: January 2023

The characteristics of photosynthesis and grain filling play a significant role in determining maize (Zea mays L.) yield. Planting density and nitrogen (N) rate are two factors affecting the growth, physiology, and grain yield of maize. The coupling effects of planting density and N rate on individual and population photosynthetic rates, grain-filling characteristics, grain yield, water use efficiency (WUE), and N partial factor productivity (NPFP) of two maize cultivars (QS51 and ZD958) under mulched drip fertigation in northwest China were investigated. Three planting densities (D1: 80,000 plants ha−1, D2: 100,000 plants ha−1, and D3: 120,000 plants ha−1) and three N rates (N0: 0 kg ha−1, N180: 180 kg ha−1, and N240: 240 kg ha−1) were designed. The results showed that the population photosynthetic rate, grain yield, WUE, and NPFP were significantly affected by planting density and N rate for both QS51 and ZD958, and their interaction had a significant effect on grain yield, WUE, and NPFP. Nitrogen application significantly improved grain-filling rates compared with N0, but there was no significant difference between N240 and N180. The D2N180 treatment obtained the maximum grain yield (15,693 kg ha−1 for QS51 and 17,644 kg ha−1 for ZD958), WUE (3.42 kg kg−1 for QS51 and 3.05 kg kg−1 for ZD958), and NPFP (98.37 kg kg−1 for QS51 and 83.93 kg kg−1 for ZD958). It was concluded that the optimized planting density and N rate improved grain yield and water-nitrogen use efficiency of QS51 and ZD958 by increasing population photosynthetic rate, grain-filling rate, and grain weight. This study enhanced our understanding of how optimized planting density and N rate maintained the sustainable maize production under mulched drip fertigation in northwest China.
The Michoacán Tsunami of 19 September 2022 on the Coast of Mexico: Observations, Spectral Properties and Modelling
Authors: Zaytsev Oleg , Tsukanova Elizaveta , Rabinovich Alexander B. , Thomson Richard E.
Published: January 2023

The Mw 7.6 earthquake of 19 September 2022 within the coastal zone of Michoacán, Mexico, generated a major tsunami that was recorded by six coastal tide gauges and a single offshore DART station. All seven instruments were located within 250 km of the source. No tsunami was detected at larger distances. Maximum wave heights were observed at Manzanillo (172 cm) and Zihuatanejo (102 cm). Numerical modelling of the event closely reproduced the coastal and offshore tsunami records and shows that the tsunami energy radiated seaward from the source as a narrow “searchlight” beam directed normal to the source and mainland coast. Estimates of the frequency content (“colour”) of the 2022 tsunami event, and that generated in 2017 by the much stronger (Mw 8.2) Chiapas earthquake further up the coast, reveal a marked difference in the tsunamigenic response. Whereas the 2017 tsunami was mostly long-period (“reddish”), with 87% of the total tsunami energy at periods >35 min, the 2022 tsunami was short period (“bluish”) with 91% of energy at periods <35 min. A noteworthy feature of the 2022 event was the seismically generated seiches observed at Puerto Vallarta, which had a recorded period of about 7 min, began immediately after the main earthquake shock, and persisted for about one hour.
Optimisation of Cereal Farm Strategies for Mitigating Externalities Associated with Intensive Production
Authors: Zhang Yusheng , Collins Adrian L.
Published: January 2023

Intensive cereal farming results in various unintended consequences for the environment including water pollution. Current uptake of on-farm best management measures in the UK is delivering limited benefits and alternative management futures need to be modelled to make informed decisions. The Farmscoper (FARMSCale Optimization of Pollutant Emission Reductions) tool was used to examine two management scenarios for intensive cereal farms in eastern England. The first was based on increased uptake of those measures currently recommended by advisory visits and following walkover surveys. The second was founded on mechanistic understanding of on-farm pollutant sources embedded in the Farmscoper tool. Optimization of measure selection used a multi-objective genetic algorithm. The technically possible reductions (e.g., 10 to 21% for sediment and 12 to 18% for total phosphorus) of current pollutant emissions to water due to uptake of the mechanistic scenario exceeded those resulting from the current advice scenario (≤5%), but with mixed impacts on costs ranging from a saving of £34.8/ha/yr to an increase of £19.0/ha/yr, relative to current best management costs. The current advice scenario generated corresponding cost savings of between £30.4/ha/yr and £73.40/ha/yr. Neither scenario is sufficiently impactful on unintended consequences, pointing to the need for structural change in land cover.

Published: January 2023

Drilling waste has a significant effect on the water quality and the aquatic environment. Therefore, the harmless solidification treatment of drilling waste mud is important in terms of protecting the water environment. However, traditional chemical solidification methods have some problems, such as wide area, high cost, and secondary pollution. Therefore, the improvement of the mechanical performance on treating the drilling waste is important, as it can reduce and minimize the effect of drilling waste on the water environment. To this end, in this study, the industrial waste residue is used as the main component of the curing agent and a harmless curing scheme is designed. According to the orthogonal design method, an unconfined compressive strength test is carried out on the solidified soil of drilling waste mud. The strength, stress-strain relationship, and deformation modulus of the solidified soil are discussed according to the curing age, the number of freeze-thaw cycles, and the proportion of the solidifying agent. The test results show that the unconfined compressive strength of solidified soil samples under different proportions increases with the increase of the curing age and decreases with the increase of the freeze-thaw cycles. With the Increase of the curing age, the solidified soil gradually changes from plasticity to brittleness, and its deformation modulus E50 also increases gradually.

Photodegradation is the chemical conversion of large, toxic, and complex molecules into non-toxic, simpler, and lower molecular weight species due to light exposure. Heterogeneous photocatalysis has sufficient potential to degrade toxic organic pollutants present in wastewater. As industries discharge their effluents containing organic pollutants into natural water bodies, which penetrate into the subsurface through connected pores it is necessary to study this process in natural or tap water. Tap water (TW) is mainly obtained from underground wells having inorganic salts in a minute quantity with a conductivity of 500 μS/cm. TW contains inorganic anions, which affect the photocatalytic activity and photocatalysis process. The aim of this review is to evaluate the effect of TW on the photo-degradation of organic pollutants such as dyes, pharmaceutical products, pesticides, etc., with the support of the literature. The TW had a diverse effect on the photodegradation of organic pollutants; either it may enhance or decrease the rate of pollutants’ photodegradation.

Published: January 2023

The coastal and carbonate Mean Sea Level Aquifer (MSLA) of Malta is characterised by high anisotropy and heterogeneity, which together make evaluating the aquifer system parameters a challenging task. In this paper, we present an approach for the determination of the hydrogeological parameters of this coastal aquifer based on tidal-induced groundwater fluctuations that can be applied in other similar contexts. This work presents an analysis of data undertaken on monitoring boreholes located in the Malta MSLA exhibiting tidal-induced groundwater fluctuations. This allowed us to determine the values of three main hydrogeological parameters: hydraulic diffusivity, transmissivity and hydraulic conductivity. These will subsequently be used as an input for groundwater flow and reactive transport modelling purposes. In this study, a methodology based on the fast Fourier transform (FFT) is proposed to improve the applicability of the Jacob–Ferris method to the observed groundwater level and sea level fluctuations. The FFT reproduced signals allowed us to isolate the component induced by sea tides, thus eliminating short- and long-term variations of the water table induced by other disruptive factors. Results showed high variability of hydrogeological parameters within a short distance, reflecting the high anisotropy and heterogeneity of the aquifer system. The transmissivity values derived from the Jacob–Ferris method are complemented with results derived from the pumping tests with the aim of estimating the spatial distribution of the aquifer transmissivity for the study area. The spatial variability of transmissivity values is analysed by means of geostatistics tools for estimating uncertainty, correlation and variation in space through the use of semi-variograms.

Published: January 2023

Bacteria produce many kinds of volatile compounds throughout their lifecycle. Identifying these volatile compounds can help to understand bacterial interactions with the host and/or other surrounding pathogens of the same or different species. Some commonly used techniques to detect these volatile compounds are GC and/or LC coupled to mass spectrometric techniques. However, these methods can sometimes become challenging owing to tedious sample preparation steps. Thus, identifying an easier method to detect these volatile compounds was investigated in the present study. Here, Membrane-inlet mass spectrometry (MIMS) provided a facile low-impact alternative to the existing strategies. MIMS was able to differentiate between the pathogenic and nonpathogenic bacterial strains, implying that it can be used as a bioprocess monitoring tool to analyze water samples from either water treatment plants or biotechnological industries.

Published: January 2023

The quality of the diet from the first hours of life is decisive. Any inappropriate diet for pregnant women or infants has an irreversible impact on a child's bio-morphological and cognitive levels,
leading to chronic malnutrition. This study assesses the factors that explain adherence to dietary taboos or restrictions and the factors statistically significantly related to the choice of nutritional restrictions in households housing stunted children under five years of age in southwest Benin.
Data were collected in December 2020 on a sample of 558 families in 40 villages in the
commune of Bopa in southwest Benin. Socioeconomic data from families, and anthropometric data from children (498) are analyzed within univariate, bivariate and binary logit regression methods.
Results show that 36.3% of children are stunted, and 76.2% of households with stunted children have food taboos. In addition, 69.6% of households have at least one taboo on consuming beef, goat, poultry, pork, eggs, and fish, reducing in-take of the required micronutrients child growth. The gender of the head of the household, their occupation, religion, level of education, age category, area of residence, level of education of
the wife of the head of the household, and average monthly household income have
statistically significant effects on adherence to food taboos and restrictions in the household diet. To effectively combat stunting, advocacy targeting religious leaders and the local elite is needed.

Published: January 2023

Abstract: This paper discusses the religiosity of Jesus among others from Levinas's perspective. Existentialist philosophy understands the "other" namely the Other. The purpose of this paper is to analyze the religiosity of Jesus through Levinas' theory of responsibility. This paper uses a qualitative research method with a literature study approach. Jesus set an example in His religiosity when meeting other people in his life. Jesus who not only cares about himself but is present in the lives of others for their salvation. For Levinas, responsibility is an action that can be carried out by humans without asking for a reply. Levinas' theory is expected to be a foundation for establishing relationships for fellow human beings and becoming an ethical moment when meeting other people. For Levinas, the Other is our responsibility to see them as people who exist. In Levinas' concept of responsibility we understand very well that when we are responsible for others it is a gift. Jesus really cares about everyone. He performs relationships and actions in the form of human values ​​because of the awareness of Himself to carry out His obligations as the savior of mankind. This concept of responsibility has been directly carried out by Jesus for the oppressed, such as the blind, lepers, and the lame being healed.
Abstrak: Tulisan ini membahas mengenai religiusitas Yesus di tengah yang lain dari perspektif Levinas. Filsafat eksistensialis memahami “yang lain” yaitu Sang Liyan. Tujuan penulisan ini ialah untuk menganalisis tentang religiusitas Yesus melalui teori tanggung jawab dari Levinas. Tulisan ini menggunakan metode penelitian kualitatif dengan pendekatan studi pustaka. Yesus menjadi teladan dalam religiusitas-Nya ketika bertemu dengan orang lain dalam kehidupannya. Yesus yang tidak hanya mempedulikan diri sendiri tetapi hadir dalam kehidupan orang lain untuk keselamatan mereka. Bagi Levinas tanggung jawab merupakan suatu tindakan yang dapat dilaksanakan oleh manusia tanpa meminta balasan. Teori Levinas ini diharapkan dapat menjadi suatu fondasi untuk menjalin relasi bagi sesama manusia dan menjadi momen etis kala berjumpa dengan orang lain. Bagi Levinas, Sang Liyan itu adalah tanggung jawab kita untuk melihat mereka sebagai orang yang bereksistensi. Dalam konsep tanggung jawab Levinas kita memahami betul bahwa ketika kita bertanggung jawab atas orang lain maka itu anugerah. Yesus sangat peduli terhadap semua orang. Dia melakukan relasi dan tindakan berupa nilai-nilai kemanusiaan karena kesadaran dari diri-Nya sendiri untuk menjalankan kewajiban-Nya sebagai Juru selamat manusia. Konsep tanggung jawab ini secara langsung sudah dilakukan oleh Yesus terhadap orang tertindas seperti, orang buta, orang kusta, orang lumpuh disembuhkan.

Tujuan pengabdian masyarakat ini adalah untuk memberikan pengetahuan, pemahaman atas sertifikat halal pada masyarakat, menambah kesadaran masyarakat akan pentingnya sertifikasi halal. Metode penelitian  dilakukan dengan sosialisasi peran sertifikat halal, penyebaran angket untuk peserta serta penilaian angket. Tolak ukur kesadaran atas sertifikasi halal masyarakat diamati mulai dari pengetahuan mengenai hukum halal, kesadaran masyarakat mengenai penerapan produk halal serta pengetahuan umum mengenai peran sertifikat halal. Hasil penilaian penyuluhan menunjukkan bahwa seluruh peserta mempunyai pengetahuan umum tentang hukum halal secara baik, semua peserta memiliki kesadaran penerapan pemakaian produk halal yang tinggi serta semua peserta mempunyai pengetahuan yang baik tentang peran dan manajemen sertifikat halal. Kesimpulan dari diskusi langsung bersama peserta menunjukkan pelaku usaha kecil belum mempunyai sertifikat halal disebabkan sosialisasi mengenai penanganan sertifikat halal yang sangat rendah dilakukan oleh pihak Pemerintah dan sebagian masyarakat masih belum mengetahui mengenai adanya Undang-Undang jaminan produk halal yang mengharuskan bahwa penyebaran semua produk dan dihasilkan di Indonesia harus mempunyai sertifikat halal.

Jumlah penderita dan kasus kematian akibat COVID-19 terus meningkat setiap harinya. Meski virus Corona menginfeksi tanpa memandang usia, sejauh ini tercatat angka kematian tertinggi di dunia akibat COVID-19 terjadi pada lansia yang berusia di atas 70 tahun. Minimnya informasi yang diperoleh lansia disebabkan karena rendahnya kepemilikan dan pemahaman terhadap penggunaan teknologi seperti android, sehingga informasi yang diperoleh sangat terbatas. Untuk itu, penting dilakukan upaya promotif dan preventif untuk mencegah penyebaran COVID-19. Melalui upaya promotif preventif, pemeriksaan kesehatan pada lansia, serta pendistribusian dan pendampingan penggunaan alat pencegahan Covid-19, dapat terwujud perilaku pencegahan penularan Covid-19 pada lansia.

Setiap daerah memang memiliki berbagai cerita legenda masa lalu, tak terkecuali di Kabupaten Tuban. Rupanya di kabupaten ujung barat Jawa Timur ini terdapat sendang petilasan Joko Tarub yang disebut-sebut sebagai tempat bertemunya Joko Tarub dengan tujuh Bidadari. Di era tahun 80-an sendang tersebut sempat menjadi objek wisata yang ramai dengan pengunjung, namun saat ini kondisi dari tempat wisata tersebut cukup memprihatinkan. Hal ini disebabkan karena dulu sendang jaka tarub itu dibuat taman karena tanah itu dimiliki oleh Pemda, setelah Pemda geger sama warga kampung karena tanah itu bukan tanah Pemda, tapi tanah warga desa dan sidang dimenangkan oleh desa, setelah itu apa-apanya diambil oleh Pemda lagi, dan akhirnya kosong karena orang desa tidak mampu membangun itu lagi. Dan sampai saat ini sendang jaka tarub masih terbengkalai dikarenakan penduduk desa warga sumberagung tidak mempunyai kesadaran penuh untuk berusaha mengembangkan objek wisata yang ada. Dengan observasi ini diharapkan wisata Sendang Jaka Tarub bisa berubah dan berkembang menjadi objek wisata yang bisa meningkatkan potensi wisata desa sumberagung dan bisa menjadi lahan penghasilan buat orang sekitar.
