Bisphenols and benzophenone UV filters are contaminants present in a wide variety of plastic materials and consumer products. The scientific attention towards these contaminants has increased in recent years due to their presence in microplastics, their ubiquitous occurrence in the environment, and their known endocrine disrupting health effects. In this study, the occurrence of nine bisphenol and five benzophenone UV-filter analogues was assessed in wild brown mussels (Perna perna) collected from different sampling sites along the coast of Algoa Bay, South Africa. Eleven out of fourteen target analytes were detected, and bisphenol AP (BPAP) was detected for the first time in mussels, presenting the highest median concentration of 150 ng g dry weight (d.w.) and a detection frequency of 91%. Regarding benzophenone UV-filters, median concentrations of the analogues (across all sites) ranged from 2.01 to 10.6 ng g d.w., with benzophenone-1 (BzP-1) and benzophenone-3 (BzP-3) presenting the highest concentrations. Human exposure was assessed by estimating daily intakes (EDI) of the target analytes through mussel consumption. To our knowledge, this is the first study from the African continent on the occurrence of bisphenols and benzophenone UV-filters in a large population (n=138) of wild brown mussels.
双酚类和二苯甲酮类紫外线滤光剂是广泛存在于各种塑料材料和消费产品中的污染物。由于它们存在于微塑料中、在环境中普遍存在以及已知对内分泌系统有干扰健康影响，近年来，科学界对这些污染物的关注有所增加。在这项研究中，评估了从南非阿尔戈阿湾沿岸不同采样点采集的野生褐贻贝（Perna perna）中 9 种双酚类和 5 种二苯甲酮类紫外线滤光剂类似物的出现情况。在 14 种目标分析物中，有 11 种被检测到，并且首次在贻贝中检测到双酚 AP（BPAP），其浓度中位数最高，为 150ng/g 干重（d.w.），检测频率为 91%。关于二苯甲酮类紫外线滤光剂，类似物（所有地点）的浓度中位数范围为 2.01 至 10.6ng/g d.w.，其中苯并酮-1（BzP-1）和苯并酮-3（BzP-3）的浓度最高。通过估计通过贻贝消费摄入目标分析物的每日摄入量（EDI）来评估人体暴露情况。据我们所知，这是非洲大陆首次在大量（n=138）野生褐贻贝中研究双酚类和二苯甲酮类紫外线滤光剂的存在情况。
