چکیده انگلیسی
An ecological project for water purification was conducted in Meiliang Bay, Lake Taihu, which supplies one-third of the drinking water for Wuxi City, China. Sediment dredging was employed. The floating-leaf and floating macrophytes were planted, combined with wave-attenuating, algal bloom blocking to improve the water quality. At the same time, large amounts of fish net were placed in the experimental zone, to which massive periphytes adhere. To evaluate the effectiveness of remediation, many studies were based on chemical analysis or acute toxicity test. In this study, chronic toxicities before and after the ecological project in Meiliang Bay, Lake Taihu, China, were evaluated based on a battery of in vitro bioassays, including EROD bioassay, recombined yeast assay, as well as umu test for detection of Ah-receptor (AhR) agonists, estrogenic chemicals and genotoxic chemicals, respectively. Before remediation, AhR effect, estrogenic effect and indirect genotoxicity were all detected in sediments of Meiliang Bay, Taihu Lake. After amelioration, levels of AhR agonists decreased by 42.3-80.7%, estrogenic chemicals decreased by 71.6-93.9% and indirect genotoxic chemicals decreased by 23.2-75.0%. Results showed that the ecological project effectively removed the chronic toxicants from the sediments.
