We have characterized the distribution of 19 AAs between cotton, wool, and polyester textiles and air. Chamber exposure experiments were conducted under controlled laboratory conditions to quantify textile–air distributions of AAs and identify key parameters impacting the distribution.

The findings suggest that cotton generally exhibits higher distribution coefficients than polyester and wool for most analytes. Overall, the results show a strong positive relationship between octanol–air distribution coefficients (<em>K</em><small>_OA</small>) and <em>K</em><small>_TA</small> values.

Waterborne fungal populations in such environments pose a unique human health concern given that opportunistic fungal pathogens can be proliferated during spray irrigation of crops. In the present study, we consider two different routes (effluent discharge <em>versus</em> bioaerosols) through which wastewater treatment plants (WWTPs) can impact the presence and abundance of fungal communities in irrigation canals of the Rio Grande river basin in New Mexico. Site A was selected to investigate the influence of effluent discharge from a WWTP on waterborne fungal communities in a receiving irrigation canal. Site B represented an irrigation canal that was directly adjacent to a WWTP but that receives no effluent discharge (to exemplify bioaerosolization exclusively). Sampling dates were chosen to capture variations in weather and stream flow conditions at each of the two sites. Results indicated that treated wastewater discharged into the canal had a distinct impact on fungal community composition, especially under low wind and flow conditions. When stream flow was highest, variations along the canal at Site A were minimal. The highest occurrence of pathogen-associated genera was observed at Site B under high wind conditions with an average relative abundance of 20.9 ± 13.1% (peak of 39.3%) and was attributable to bioaerosol emissions from the WWTP and a nearby livestock facility. Such genera included <em>Alternaria</em>, <em>Cladosporium</em>, and <em>Cryptococcus</em>.

The current ban on traditional pesticides and ongoing replacement of current-use pesticides (CUPs) have not been accompanied by extensive research on the presence of CUPs in reservoirs, which are vital centralized sources of drinking water. In this study, 26 CUPs was investigated in a drinking water source reservoir, the surrounding watershed, and the surrounding agricultural and domestic discharge water in Hainan Province. The predominant detected CUPs in the study area were clothianidin (CLO), thiamethoxam (THM), acetamiprid (ACE), imidacloprid (IMI), and dichlorvos (DCH). Neonicotinoids (NNIs) were the primary type of pesticide contamination in the study area, with a concentration ranging from not detected (n.d.) to 755 ng L<small>⁻¹</small> (median of 71.0 ng L<small>⁻¹</small>). The upstream watersheds of the reservoir were primarily contaminated due to agricultural activities, and the highest concentration of individual CUPs, ranging from 102 to 821 ng L<small>⁻¹</small> (median of 468 ng L<small>⁻¹</small>), was found in agricultural source water. Source identification analysis revealed that the presence of CUPs in the reservoir primarily stemmed from three types of activities: the cultivation of fruit trees around the reservoir, the daily activities of residents, and the agricultural practices in the upstream watershed basin. Risk assessment indicated that DCH, IMI, and THM posed moderate or high risks to aquatic organisms, with an emphasis on the effects of NNIs. The chronic cumulative risk assessment of NNIs was conducted by the relative potency factor approach, and it indicated that infants and young children were the most vulnerable groups and exhibited heightened susceptibility. The potential exposure to NNIs through drinking water was below the recommended relative chronic reference dose, thereby posing no discernible health risks.

Herein, a pot experiment was performed to investigate the effects of sodium silicate application on pak choi growth, oxidative status, Cd uptake and accumulation in pak choi, soil Cd bioavailability and fractions, and soil bacterial communities. The results showed that sodium silicate application significantly increased soil pH (0.29–1.61 units) and induced the transformation of the Cd fraction from an exchangeable fraction (Exc-Cd) into an iron and manganese oxide-bound fraction (OX-Cd) and organic matter-bound fraction (OM-Cd), decreasing Cd bioavailability by 13.7–20.8% in Cd-contaminated acidic soil. As a result, sodium silicate application significantly alleviated Cd toxicity, enhanced pak choi growth, and reduced Cd concentration in roots by 23.5–89.0% and in shoots by 58.5–81.0%, with Cd concentration in the edible part at a Si application rate equal to or greater than 0.4 g Si per kg soil falling below the safety limits for Cd as defined in China's food safety standard (GB 2762-2022). In addition, sodium silicate application significantly increased soil bacterial richness (Ace index and Chao1) and diversity (Shannon and Simpson index) and altered the soil microbial structure.

Recent research indicates that leachate of historic landfills can contain elevated concentrations of per- and polyfluoroalkylated substances (PFAS), but there is limited data on resulting PFAS inputs to aquatic ecosystems as might inform on this potential environmental threat. The objective of this study was to evaluate PFAS exposure in three ecological zones and PFAS mass loading downstream, over 1 year, at two historic landfill sites where landfill plumes discharge to nearby surface waters (1 pond with outlet stream, called HB site; 1 urban stream, called DC site). The three zones experienced different magnitudes and patterns of PFAS concentration exposure (<em>i.e.</em>, contaminant presence in the zone). The endobenthic zone of the sediments receiving the landfill plumes experienced the highest concentrations (∑PFAS &gt;4000 ng L<small>⁻¹</small> (HB) and &gt;20 000 ng L<small>⁻¹</small> (DC)), often year-round and over a substantial area at each site. Dilution of landfill PFAS in surface waters was observed though concentrations were still elevated (∑PFAS: &gt;120 ng L<small>⁻¹</small> (HB) and &gt;60 ng L<small>⁻¹</small> (DC)), with evidence of year-round pelagic zone exposure. PFAS concentrations in the epibenthic zones could vary between that of the endobenthic and pelagic zones, sometimes with daily, event-based, and longer-term patterns. Together these findings suggest historic landfill plumes can lead to substantial PFAS exposure to a variety of aquatic life. Downstream PFAS mass loadings during base flows were relatively small individually (15 (HB) and 36 (DC) g per year (∑PFAS)); however, collective loadings from the numerous historic landfills in a watershed could contribute to increasing PFAS concentrations of connected water bodies, with implications for ecological health, drinking water sources, and fisheries.</p>","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" 4","pages":" 1074-1087"},"PeriodicalIF":4.3,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/em/d4em00612g?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
