24种个人护理品在鱼血浆中的富集特征及风险

Bioaccumulation of Personal Care Products in the Plasma of Wild Fish from the Dongjiang River and the Associated Risks

  • 摘要: 对东江流域8个典型区域的32个野生鱼血浆样品进行了监测,分析了24种个人护理品活性成分在血浆中的含量水平、存在形态和富集潜力,并进行了生态风险评价.鱼体血浆中检出13种个人护理品活性成分,质量浓度范围从低于MQLs(检测限)至208 ng/mL,三氯生的检出浓度最高.其中,避蚊胺、尼泊金甲酯和佳乐麝香在每个采样点的鱼体内均有检出,检出率高于90%. 4种尼泊金酯和三氯生在鱼体血浆中主要以葡糖醛酸化/硫酸化结合态的形式存在.吐钠麝香、佳乐麝香、三氯卡班、三氯生在鱼体血浆中的生物富集系数对数值(lg BAFs)范围为2.43~4.25,较易富集;氯咪巴唑和苯并三唑在鱼体血浆中的lg BAFs范围为0.35~1.99,较难富集.风险评价结果表明,吐钠麝香的效应因子(ER)低于1,表现为高风险;佳乐麝香、苯并三唑、三氯生和避蚊胺的效应因子低于10,表现为较高风险.后续研究中应该关注这几种物质的潜在生态风险.

     

    Abstract: The concentrations of 24 personal care products in the plasma of 32 wild fish collected from the 8 typical regions of the Dongjiang River were detected and the speciation and bioaccumulation potency and risk of the 24 targets were also analyzed. 13 personal care products ingredients were found in the plasma of fish, with the concentrations ranging from < MQLs to 208 ng/mL (triclosan). The N, N-diethyl-3-methylbenzamide, methylparaben and galaxolide were found in the fish collected from each of 8 sampling sites, and the detection frequencies of all these chemicals were higher than 90%. The 4 parabens and triclosan mainly exist in the plasma of fish with the conjugated (glucuronide or sulfate metabolites) forms. The tonalide, galaxolide, triclocarban and triclosan were more likely to be accumulated, with the logarithm values of bioaccumulation factors (lg BAFs) ranging from 2.43 to 4.25 in fish plasma; the climbazole and benzotriazole were less likely to be accumulated, with the lg BAFs ranging from 0.35 to 1.99. The result of risk assessment indicated that the tonalide was identified as a major chemical, with the effect ratio (ER) lower than 1; galaxolide, benzotriazole and triclosan were recognized as the medium risk chemicals, with ER lower than 10. The potential biological and ecological risks of these chemicals should be attended to in the future study.
