Abstract

Emerging chemicals (ECs), including parabens, bisphenols, bisphenol diglycidyl ethers, N,N′-substituted p-phenylenediamines, and benzotriazoles/benzothiazoles (BTH/BTRs), are widely used in industrial and consumer products. This study aimed to determine the urinary concentrations of 33 ECs and three oxidative stress biomarkers in pregnant women from a large birth cohort in Jiashan, China. Among the detected compounds, methyl paraben (MeP), bisphenol A (BPA), bisphenol A bis(2,3-dihydroxypropyl) glycidyl ether (BADGE·2H₂O), N-isopropyl-N′-phenyl-1,4-phenylenediamine quinone (IPPDQ), and 1H-benzotriazole (1-H-BTR) were the most prevalent, with median concentrations ranging from 0.51 to 9.02 ng/mL. Notably, BTH/BTRs exhibited the highest exposure levels, approximately 4–16 times greater than those of other ECs. Most ECs showed elevated concentrations in pregnant women who were exposed to secondhand smoke prior to pregnancy. After model analysis, we found that mixtures of ECs were positively associated with both 8-hydroxy-2′-deoxyguanosine (8-OHdG) and 15(R)-prostaglandin F_2α (15-PGF_2α), while a negative trend was observed between ECs and 8-iso-prostaglandin F_2α (8-PGF_2α). Specifically, urinary benzyl paraben (BzP), BPA, bisphenol S (BPS), N-(1,3-dimethylbutyl)-N′-phenyl-1,4-phenylenediamine quinone (6PPDQ), IPPDQ, 2(3H)-benzothiazole (2-OH-BTH), and 2-methylthio-benzothiazole (2-Me-S-BTH) or 1-H-BTR were significantly (p < 0.05) associated with 8-OHdG. MeP, 6PPDQ, and 2-Me-S-BTH were linked to 15-PGF_2α, while only bisphenol A (2,3-dihydroxypropyl) glycidyl ether (BADGE·H₂O) showed a significant positive association with 8-PGF_2α. This study provides a comprehensive evaluation of the exposure characteristics of ECs and their associations with oxidative stress biomarkers in pregnant women, offering new insights into the health risks associated with ECs exposure during critical periods of pregnancy.

期刊介绍： Emerging Contaminants is an outlet for world-leading research addressing problems associated with environmental contamination caused by emerging contaminants and their solutions. Emerging contaminants are defined as chemicals that are not currently (or have been only recently) regulated and about which there exist concerns regarding their impact on human or ecological health. Examples of emerging contaminants include disinfection by-products, pharmaceutical and personal care products, persistent organic chemicals, and mercury etc. as well as their degradation products. We encourage papers addressing science that facilitates greater understanding of the nature, extent, and impacts of the presence of emerging contaminants in the environment; technology that exploits original principles to reduce and control their environmental presence; as well as the development, implementation and efficacy of national and international policies to protect human health and the environment from emerging contaminants.
