On May 15, 2020, Liu, Jianchao; Lu, Guanghua; Yang, Haohan; Dang, Tianjian; Yan, Zhenhua published an article.Formula: C24H27NO2 The title of the article was Ecological impact assessment of 110 micropollutants in the Yarlung Tsangpo River on the Tibetan Plateau. And the article contained the following:
In this study, the occurrences of 110 micropollutants in the surface waters and sediments collected at eight sampling sites along the middle reaches of the Yarlung Tsangpo River were investigated in winter. A total of 47 and 45 micropollutants were detected in at least one water or sediment sample, resp., and their total concentrations reached 790.2 ng/L and 186.5 ng/g on a dry weight basis, resp. Their composition profiles demonstrated that the majority of micropollutants were polycyclic aromatic hydrocarbons (PAHs) and UV filters. The mixture risk quotient (MRQ) values of the detected micropollutants regularly exceeded 1 for aquatic organisms at all sampling sites, and fish and invertebrates are the more sensitive organisms. The diversity and evenness of the zooplankton levels had a clear neg. correlation with the micropollutant occurrences in water. The top 10 mixture components belonging to the UV filter and PAH categories explained more than 80% and 95% of the mixture risk for chronic and acute toxicol., resp. This study is the first investigation of the presence and risk assessment of 110 micropollutants in the Yarlung Tsangpo River Basin and offers new insights into the ecol. security of the water resources of the Tibetan Plateau. The experimental process involved the reaction of 2-Ethylhexyl 2-cyano-3,3-diphenylacrylate(cas: 6197-30-4).Formula: C24H27NO2
