Objective The effect of environmental pollution on sleep has been widely studied, yet the relationship between exposure to volatile organic compounds (VOCs) and health requires further exploration. We aimed investigate single mixed urinary VOC metabolites identify potential mediators. Methods Data for this cross-sectional study was collected from National Health Nutrition Examination Surveys (NHANES) (2005–2006, 2011–2014). A weighted multivariate logistic regression established explore associations 16 VOCs with four outcomes. Following selection important through least absolute shrinkage operator (LASSO) regression, principal component analyses (PCA), weight quantile sum (WQS), Bayesian kernel machine (BKMR) were conducted outcomes, as well most contributing components. mediation analysis performed depression scores. Results Of 3,473 participants included in study, a total 618 diagnosed poor patterns. In analyses, 7, 10, 1, 5 significantly positively correlated patterns, abnormal duration, trouble sleeping, disorders, respectively. PCA showed that PC1 substantially linked higher risk patterns its WQS model revealed positive association mixture increased concentrations [OR (95% CI): 1.285 (1.107, 1.493)], duration 1.154 (1.030, 1.295)], sleeping 1.236 (1.090, 1.403)] disorders 1.378 (1.118, 1.705)]. BKMR found overall disorders. PCA, WQS, models all confirmed significant role N -acetyl- S -( -methylcarbamoyl)- l -cysteine (AMCC) score mediator index Conclusion Exposure negatively affected American population, AMCC playing role. shown mediate mixtures

Abstract With the increasing development of industry, polycyclic aromatic hydrocarbons (PAHs) pollution is becoming increasingly serious, posing great harm to health humans and other organisms. It urgent develop effective solutions.In this study, DNA/calcium alginate magnetic aerogel microspheres were prepared based on gel properties sodium magnetism ferric oxide, which used remove benzo(a)anthracene (BaA) from aqueous solution. The irregular spherical, with concave convex surface good water absorption. pores mostly mesoporous. had adsorption BaA easy be magnetically separated. When initial concentration was 350 µg/L, removal efficiency 98.52% when incubated at 25 ℃ pH 7.0 for 50 min. process accorded Langmuir model pseudo-2nd -order kinetic model. For natural river samples containing BaA, above 98.45% in range 50–300 µg/L.The have high capacity, simple time-consuming, potential application value purification.
