The study area is the source area of the Eastern Route (ER) of the South-to-North Water Diversion Project (SNWDP), typical of the lower alluvial plain of the lower Yangtze River. Water samples from monitoring wells and domestic wells were collected to analyze common variables (pH, EC), major ions, trace metals, etc. The water quality index method was employed to evaluate groundwater quality in both eastern and western parts of the study area. The study found that the groundwater hydrochemistry is typical of HCO₃-Ca and HCO₃-Na, similar between the eastern and western parts of the study area. In addition, the eastern part of the study area is more affected by nitrate pollution than the western part due to agricultural activities. The water quality analysis suggests that the groundwater in the western region was slightly better than that in the eastern region. The comparison between different scenarios indicates that the water quality using only major ions can differ significantly from that using all chemical parameters, but may offer some preliminary insights into the groundwater quality useful for conducting further more detailed analysis. Our study shows that using the combination of major ions and heavy metals could provide relatively robust results of the groundwater quality in our study area.

Recently, there has been growing interest in utilizing microorganisms to aid in PE decomposition. Molecular docking and molecular dynamics simulations are valuable tools for understanding specific mechanisms and conducting initial screenings to support experimental research in this context. In this study, various enzymes, including lignin peroxidase, laccase, manganese peroxidase, and cutinase, sourced from Phanerodontia chrysosporium, Melanocarpus albomyces, and Fusarium vanettenii, were investigated. The docking simulations revealed that lignin peroxidase exhibited the most substantial binding interaction with PE, displaying a binding energy of - 4.69162 kcal mol^-1 and an RMSD value of 0.93428 Å. Following lignin peroxidase in binding strength were laccase, manganese peroxidase, and cutinase. Furthermore, molecular dynamics simulations provided insights into the binding mechanisms. These simulations demonstrated stability over a 200-ns period, as indicated by RMSD and RMSF values below 0.2 nm. Additionally, the study delved into the interaction mechanisms between microorganisms and plastic molecules, enriching our understanding of this process.

Samples (n = 5) from dead individuals were first digested then separated on the basis of density followed by vacuum filtration prior to quantification of MPs through stereomicroscopy. Fourier Transform Infrared Spectroscopy (FTIR) was used to identify the chemical composition of MPs.

Polyvinyl alcohol (PVA), polyisobutylene, polyaramid, fiberglass and PTFE coated fiberglass fiber were characterized as the major constituent compounds of MPs in gastrointestinal tracts of cattle egrets. Highest concentrations of sheets and fibers MPs in gastrointestinal tract of cattle egrets reflect their greater sources and lowest degradation.

Ruminal contents from slaughtered rams and steers were used as inoculum for in vitro fermentation system. The total gas, methane, carbon monoxide, and hydrogen sulfide volume, as well as pH and dry matter degradability, were quantified in three fermentation cycles. Probiotic bacteria reduced the production of methane and hydrogen sulfide, while also increasing (P < 0.05) dry matter biodegradability, short-chain fatty acids, and metabolizable energy in both rams and steers. Delonix regia seeds at 6, 12, and 18% reduced total gas production. Higher production of methane and carbon monoxide was observed in rams compared to steers. Interestingly, no impact (P > 0.05) on the pH of the ruminal contents was found in Delonix regia seeds alone or in combination with probiotics. However, higher (P < 0.05) methane conversion efficiency (i.e., ratios of methane: short-chain fatty acids, methane: metabolizable energy, and methane: organic matter) was observed in experimental diets with Delonix regia seeds compared to diets containing both Delonix regia seeds and probiotic bacteria. In conclusion, dietary inclusion of 6, 12, and 18% of Delonix regia seeds with probiotic bacteria (Pediococcus acidilactici BX-B122 and Bacillus coagulans BX-B118) can mitigate the production of methane and hydrogen sulfide, while also increasing dry matter biodegradability, short-chain fatty acids, and metabolizable energy both ruminant animals.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ebullitive CH₄ emissions from the wetlands, particularly the mountain wetlands of Eastern Himalayan, are poorly understood. To gain insights into the role of ebullition in CH₄ emissions and understand the factors influencing CH₄ ebullition, we conducted field measurements of the spatial and temporal variation of ebullition in a freshwater wetland area in floating national park (40 sq. km, 780 m amsl, maximum depth < 4.5) in Northeast India. The average ebullitive CH₄ flux ranged from 220.24 to 1889.35 mg m^-2 d^-1, while the overall CH₄ fluxes varied widely ranging from 345.81 to 2240.56 mg m^-2 d^-1. Methane constituted 90.18% of the gas bubbles produced from the sediment, with CO₂ comprising 8.82% of the total sediment gas in the wetland. This suggests that CH₄ emission through ebullition plays an important role in transporting biogenic CH₄ to the atmosphere. The ebullition rate was markedly higher during summer and lower during winter and exhibited a significant seasonal variation. At a spatial scale, the sites with dense aquatic vegetation growth increase CH₄ emission where plants derived autochthonous sediment organic matter, substantiating the supply of carbon substrate for CH₄ production. Linear mixed-effect models revealed that water temperature, organic matter, organic carbon and dissolved organic matter are the important factors affecting the ebullitive methane flux. Our results indicate that mountainous wetlands with organic-rich sediments may be potential hotspots for CH₄ ebullition. However, the lack of information on these wetlands in the scientific literature emphasizes the need for further research.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concentrations of pharmaceutical residues (ng L^-1) such as NSAIDs, corticosteroids, proton pump inhibitors, H2-receptor antagonists, and heavy metals (mg L^-1) like Cd, As, Cu, Cr, Hg, Ni, Pb, and Zn were meticulously quantified. The effluent exhibited a significant embryolethal potential with an LC₅₀ of 2.328% and an EC₅₀ for malformation at 2.607%. Notable embryonic malformations included yolk sac edema, tail abnormalities, pericardial edema, scoliosis, craniofacial deformities, eye hypopigmentation, developmental delays, and body malformations. Zebrafish embryos were exposed to varying concentrations of the effluent (0.5% to 4.0%) and assessed for lethality and malformations at specific intervals (12, 24, 48, 72, and 96 h post-fertilization).
