Municipal wastewater contains numerous chems. and transformation products with highly diverse physiochem. properties and intrinsic toxicity; thus, it is imperative but challenging to identify major toxicants. Herein, toxicity identification evaluation (TIE) was applied to identify major toxicants in a typical municipal wastewater treatment plant (WWTP). Impacts of chem. properties on the removal of contaminants and toxicity at individual treatment stages were also examined The WWTP influent caused 100% death of Daphnia magna and zebrafish embryos, and toxicity characterization suggested that organics, metals, and volatiles all contributed to the toxicity. Toxicity identification based on 189 target and approx. one-thousand suspect chems. showed that toxicity contributions of organic contaminants, metals, and ammonia to D. magna were 77%, 4%, and 19%, resp. Galaxolide, pyrene, phenanthrene, benzo[a]anthracene, fluoranthene, octinoxate, silver, and ammonia were identified as potential toxicants. Comparatively, the detected transformation products elicited lower toxicity than their resp. parent contaminants. In contrast, the analyzed contaminants showed negligible contributions to the toxicity of zebrafish embryos. Removal efficiencies of these toxicants in WWTP were highly related to their hydrophobicity. Diverse transformation and removal efficiencies of contaminants in WWTPs may influence the chem. compositions in effluent and ultimately the risk to aquatic organisms in the receiving waterways. In the experiment, the researchers used many compounds, for example, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8Reference of 1563-38-8).
2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.Reference of 1563-38-8
