摘要

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;00:1-8. (c) 2021 SETAC
