摘要： Perfluorinated compounds (PFCs), represented by perfluorooctane sulfonate (PFOS), are a major kind of new persistent organic pollutant, and also one of the common pollutants in water environment. At present, there is a lack of an overall and systematic evaluation of the PFOS toxicity on the entire food chain in rivers. In this paper, Daphnia magna Straus is selected as the representative of zooplankton, chlorella vulgaris is selected as the representative of phytoplankton, and zebrafish and carp are selected as the representatives of fish. The static microecological experimental method is used to have a systematic study of the acute toxicity of PFOS on zooplankton, phytoplankton and fish. Results show that PFOS has an obvious toxic effect on zooplankton, phytoplankton and fish. At certain concentration, PFOS can inhibit the growth of phytoplankton, and exert a lethal effect on zooplankton and fish. The toxic effect is in positive correlation with the concentration of PFOS. PFOS has an obvious toxic effect on fish, and also on the food of fish such as phytoplankton and zooplankton.
