Abstract

Endocrine disruptors chemicals (EDCs) pose significant health risks, including cancer, behavioral disorders, and infertility. In this study, we employed the photoelectrocatalysis (PEC) technique with optimized tungsten oxide (WO₃) nanostructures as a photoanode to degrade three diverse EDCs: methiocarb, dimethyl phthalate, and 4-tert-butylphenol. PEC degradation tests were carried out for individual contaminants and a mixture of them, assessing efficiency across different EDC families. Ultra High-Performance Liquid Chromatography and Mass Spectrometry was used to control the course of the experiments. For individual solutions, 4-tert-butylphenol and methiocarb were 100% degraded at 1 hour of PEC degradation. Among the tested EDCs, dimethyl phthalate showed the highest resistance to degradation when treated individually. However, when assessed in a mixture with the other EDCs, the degradation efficiency of dimethyl phthalate increased compared to its individual treatment. Furthermore, four degradation intermediates were identified for each contaminant. Finally, toxicity tests revealed that the initial solution was more toxic than the samples treated for all the contaminants tested, except for the phthalate.

光电催化是降解内分泌干扰物化学物质的有效方法吗？

内分泌干扰物化学物质（EDCs）对健康构成重大风险，包括癌症、行为紊乱和不孕不育。在这项研究中，我们采用光电催化（PEC）技术，以优化的氧化钨（WO3）纳米结构作为光阳极，降解了三种不同的 EDC：甲硫克百威、邻苯二甲酸二甲酯和 4-叔丁基苯酚。对单个污染物和它们的混合物进行了 PEC 降解测试，以评估不同 EDC 家族的效率。超高效液相色谱法和质谱法用于控制实验过程。就单个溶液而言，在 PEC 降解 1 小时后，4-叔丁基苯酚和甲硫威的降解率达到 100%。在测试的 EDC 中，邻苯二甲酸二甲酯在单独处理时显示出最高的耐降解性。不过，在与其他 EDC 混合进行评估时，邻苯二甲酸二甲酯的降解效率比单独处理时有所提高。此外，每种污染物都确定了四种降解中间体。最后，毒性测试表明，对于除邻苯二甲酸酯以外的所有受测污染物，初始溶液的毒性均高于经过处理的样品。

期刊介绍： Environmental Toxicology and Pharmacology publishes the results of studies concerning toxic and pharmacological effects of (human and veterinary) drugs and of environmental contaminants in animals and man. Areas of special interest are: molecular mechanisms of toxicity, biotransformation and toxicokinetics (including toxicokinetic modelling), molecular, biochemical and physiological mechanisms explaining differences in sensitivity between species and individuals, the characterisation of pathophysiological models and mechanisms involved in the development of effects and the identification of biological markers that can be used to study exposure and effects in man and animals. In addition to full length papers, short communications, full-length reviews and mini-reviews, Environmental Toxicology and Pharmacology will publish in depth assessments of special problem areas. The latter publications may exceed the length of a full length paper three to fourfold. A basic requirement is that the assessments are made under the auspices of international groups of leading experts in the fields concerned. The information examined may either consist of data that were already published, or of new data that were obtained within the framework of collaborative research programmes. Provision is also made for the acceptance of minireviews on (classes of) compounds, toxicities or mechanisms, debating recent advances in rapidly developing fields that fall within the scope of the journal.
