In the present study, chinonomus riparius larvae were selected as a model organism, and 11 sediment samples from the Xihe River in Shenyang underwent toxicity identification evaluation (TIE) to identify sediment toxic pollutants. Heavy metals and organic pollutants were the main toxic pollutants through toxicity screening and characterization. The results of toxicity identification showed that the pollution level from Cd was most serious and that phenol and P-methyl phenol were the major organic pollutants. Moreover, a spiking test of Cd was conducted, which indicated that Cd was the main toxic pollutant of sediments at sites 4, 6, 7, 8, and 10. We confirm that TIE is the most effective method to determine the relationship between toxic effects and toxic pollutants. Environ Toxicol Chem 2021;40:3103–3110. © 2021 SETAC

西河沉积物毒性鉴定评价

本研究以河鲀幼虫为模型生物,对沉阳西河11个沉积物样品进行毒性鉴定评价(TIE),对沉积物有毒污染物进行鉴定。通过毒性筛选和表征,重金属和有机污染物是主要的有毒污染物。毒性鉴定结果表明,镉的污染程度最为严重,苯酚和对甲基苯酚是主要的有机污染物。此外,还进行了 Cd 的加标试验,表明 Cd 是 4、6、7、8 和 10 号位点沉积物的主要有毒污染物。我们确认 TIE 是确定毒性效应之间关系的最有效方法和有毒污染物。环境毒物化学2021;40:3103–3110。© 2021 SETAC
