In the last few decades, there has been a growing interest in understanding the behavior of personal care products (PCPs) in the aquatic environment. In this regard, the aim of this study is to estimate the accumulation and effects of four PCPs within the clam Ruditapes philippinarum. The PCPs selected were triclosan, OTNE, benzophenone-3, and octocrylene. A progressive uptake was observed and maximum concentrations in tissues were reached at the end of the exposure phase, up to levels of 0.68 µg g, 24 µg g, 0.81 µg g, and 1.52 µg g for OTNE, BP-3, OC, and TCS, respectively. After the PCP post-exposure period, the removal percentages were higher than 65%. The estimated logarithm bioconcentration factor ranged from 3.34 to 2.93, in concordance with the lipophobicity of each substance. No lethal effects were found although significant changes were observed for ethoxyresorufin O-demethylase activity, glutathione S-transferase activity, lipid peroxidation, and DNA damage.
在过去几十年中,人们对了解个人护理产品(PCPs)在水生环境中的行为越来越感兴趣。在这方面,本研究的目的是评估四种个人护理产品在菲律宾蛤仔(Ruditapes philippinarum)体内的积累情况及其影响。所选择的个人护理产品为三氯生、OTNE、二苯甲酮-3和二乙氨羟苯甲酰基苯甲酸己酯。观察到蛤仔对这些物质的吸收呈渐进性,在暴露阶段结束时组织中的浓度达到最高,OTNE、二苯甲酮-3、二乙氨羟苯甲酰基苯甲酸己酯和三氯生在组织中的最高浓度分别达到0.68微克/克、24微克/克、0.81微克/克和1.52微克/克。在个人护理产品暴露期结束后,去除率高于65%。估计的对数生物富集系数在3.34至2.93之间,这与每种物质的疏脂性一致。虽然观察到乙氧基异吩唑酮O-脱甲基酶活性、谷胱甘肽S-转移酶活性、脂质过氧化和DNA损伤有显著变化,但未发现致死效应。
