Personal care products in wild fish in two main Chinese rivers: Bioaccumulation potential and human health risks

摘要

AbstractPersonal care products (PCPs) are widely applied in our daily life, however, little is known about their occurrence in wild fish. We investigated the bioaccumulation and potential risks of 24 PCPs in muscle and liver tissues of wild fish collected from two large rivers of Pearl and Yangtze Rivers in China. The results showed the detection of a total of 13 PCPs including 9 biocides, 2 synthetic musks and 2 benzotriazoles in at least one type of fish tissue from 12 fish species. The compounds with high detection frequencies (>50%) in fish muscle or liver tissues wereN,N-diethyl-3-methylbenzamide, carbendazim, climbazole, miconazole (MCZ), methylparaben, propylparaben, triclosan (TCS), tonalide, galaxolide (HHCB) and 5-methyl-1H-benzotriazole (5-TT). Among biocides, synthetic musks and benzotriazoles, TCS, HHCB and benzotriazole showed the maximum concentrations of 79.5ng/g wet weight (ww), 299ng/g ww and 3.14ng/g ww, respectively, in muscle tissue, while MCZ, HHCB and 5-TT showed the maximum concentrations of 432ng/g ww, 2619ng/g ww and 54.5ng/g ww, respectively, in liver tissue. The median values of logarithm of bioaccumulation factors (BAF) for the detected 13 PCPs were ranged 0.8–3.35 in muscle and 0.85–4.58 in liver. The log BAF values of the PCPs displayed good linear relationships with logKowand logDow(pH-dependentKow). The health hazard assessment of 10 detected PCPs in the muscle indicated no appreciable risk to human via consumption of the wild fish.Graphical abstractDisplay OmittedHighlights•Levels of personal care products (PCPs) in wild fish tissues were investigated.•Thirteen PCPs were found in muscle/liver tissues up to thousands ng/g wet weight.•The log BAF displayed good linear relationships with logKowand logDow.•No appreciable health risk to human via the consumption of wild fish muscle
