Abstract: Sediments are considered a repository of many organic pollutants. In this work, organic pollutants are extracted in the sediments from Huangpu River and Suzhou Creek in Shanghai using Soxhlet. The comprehensive toxicity of the sediment organic extractions to three cell proliferations including normal liver cells L02, hepatoma cells HepG2 and human breast cancer cells MCF-7 cells using the CCK-8 assay is evaluated. Proliferation toxicity differences of the sediment organic extracts on the three cells were compared. The results showed that the sediment organic extractions of Huangpu River and Suzhou Creek exhibited different toxic effects on the three cells. For L02 and HepG2, most samples showed positive cell proliferation effect or no effect; while for MCF-7 cells, majority of the samples have different degree toxic effects on MCF-7 cell proliferation and presented dose-effect dependent and time-effect dependent relationships. Besides, the toxicity effect for MCF-7 cell proliferation had a great relevance with the location of sampling. That Huangpu River and Suzhou Creek sediments were polluted by some organic toxicity pollutants can be concluded. In addition, sediments from the two rivers showed a similar toxic effect on the proliferation of L02, HepG2 and MCF-7 cells, indicating that pollution intensity and types of organic pollutants in the two rivers are similar.
