Commercial dissolvable gelatin filters are efficient samplers but can only dissolve in warm water. This study developed nanofiber gelatin filters that can rapidly dissolve in room-temperature water, facilitating on-site sampling and detecting of airborne bacteria when combined with adenosine triphosphate (ATP) analysis. To enhance the dissolvability of gelatin filters, the electrospinning technique was employed to fabricate the nanofiber filters with a high surface area but low mass. The physical and biological sampling efficiencies of the developed filters were then measured using NaCl particles and airborne bacteria, respectively. The feasibility of on-site detection of airborne bacteria was demonstrated through laboratory and field tests.

The physical sampling efficiency was 98.96%, and the biological sampling efficiency was 90% higher than that of the standard Andersen impactor.

For treatments without ferrous sulfide (FeS) precipitation, the solution-to-solid ratio (<em>R</em><sub>L/S</sub>) of DPAA increased slightly and dramatically with iron reduction, respectively, for P-Fe<sub>o</sub> and P, suggesting that the reduction of non-crystalline iron contributes more to DPAA mobilization than crystalline iron.

The degree to which iron reduction facilitates DPAA mobilization or sequestration is likely determined by the composition and amount of iron in paddy soil, respectively. For treatments with FeS, the DPAA transformation rate was &lt; 44% and 74-86%, respectively, in P-Fe<sub>o</sub> and P-Fe<sub>d</sub> after 90 days, with the maximum value comparable to those without FeS in P after 30 days.

However, research on the combined effects of multiple pesticides on atherosclerotic cardiovascular disease (ASCVD) is limited, particularly in rural areas. Despite advances in toxicogenomics, the mechanisms underlying these effects remain unclear. This study aims to investigate the combined effects and mechanisms of pesticide exposures on ASCVD.<h3>Methods</h3>In the cross-sectional study section, 2291 participants were included. Variables were filtered using machine learning models, and associations between mixed exposure to multiple pesticides and ASCVD were explored using environmental mixed exposure models (weighted quartile sum (WQS) regression and quantile-based g-computation (QGC)). In the bioinformatics analysis section, the GEO, CTD, Malacards, and GeneCards databases were used to retrieve target genes for pesticide exposure and atherosclerotic diseases. Enrichment analysis was then performed to identify the biological pathways associated with these genes.<h3>Results</h3>Three machine models screened 34 pesticides. Single pesticide exposures, such as atrazine, oxadiazon, p,p'-DDE, α-BHC, β-BHC, fenitrothion, malathion, fenitrothion, cypermethrin, cypermethrin, and cypermethrin might increase the 10-year ASCVD risk (all P &lt; 0.05). Total mixed pesticide exposure was positively associated with 10-year ASCVD risk in both the QGC (3.223(2.196, 4.730)) and WQS models (4.642(3.070, 7.020)). Notably, there was a linear relationship between total<sub>QGC</sub> (P_<sub>overal</sub> &lt; 0.001; P_<sub>nonlinearity</sub> = 0.864) and high 10-year ASCVD risk. In toxicogenomic bioinformatics analysis, we identified 112 potential atherosclerosis target genes affected by pesticide exposure. Pathway enrichment analysis suggests pesticide-induced atherosclerosis is linked to pathways such as metabolic pathways, lipid metabolism, MAPK, AMPK, FoxO signaling, apoptosis, fluid shear stress, endocrine resistance, TNF, and PI3K-Akt. Key genes were identified based on maximal clique centrality, including AKT1, TP53, IL6, BCL2, TNF, JUN, PTGS2, CASP3, MAPK3, and CASP9.<h3>Conclusion</h3>Individual and combined exposure to pesticides increased the 10-year ASCVD risk, especially in patients with T2DM. Mixed levels of pesticide exposure were linearly and positively associated with high 10-year ASCVD risk. The mechanism of atherogenesis by mixed pesticide exposure may involve pathways such as lipid metabolism, MAPK, AMPK, FoxO signaling, apoptosis, fluid shear stress, endocrine resistance, TNF, and PI3K-Akt.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"234 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

The OM-rich layers distinctively contain As-rich layers concentrated at the margins of the siderite layers, while they have numerous As-rich hotspots coexisting with S and amorphous OM.

Four key factors were identified as drivers of HMs contamination: natural sources (30.36%, influenced by soil type), mixed agricultural and transportation sources (29.56%, driven by cropland, aquaculture, and road density), human activities (12.68%, including population density and community activities), and industrial sources (27.42%, linked to factories and enterprises).

No significant associations were observed for O<sub>3</sub> and SO<sub>2</sub>. NO<sub>2</sub> had a linear exposure-response curve; PM<sub>2.5</sub> and PM<sub>2.5-10</sub> showed stronger effects at lower exposures, while CO’s effect increased at higher exposures. Furthermore, the impact was greater during the cold season.<h3>Conclusions</h3>This large-scale national study highlights the significant association between short-term exposure to PM<sub>2.5</sub>, PM<sub>2.5-10</sub>, NO<sub>2</sub>, and CO and kidney failure exacerbation, providing novel insights into the combined effects of air pollution on kidney failure.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"97 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
