Abstract:The toxicity data of priority pollutants of five representative freshwater zoobenthos were collected and screened according to the water quality criteria derivation guidelines of the US and the lists of priority pollutant of EU、USA and China. The five zoobenthos included Chironomus tentans、Macrobrachium rosenbergii、Corbicula manilensis、Limnodrilus hoffmeisteri and Misgurnus anguillicaudatus. A list of ten priority pollutants that were most toxic to the five zoobenthos was obtained, and it mainly included two categories of chemicals — organochlorine pesticides and heavy metals. Species sensitivity distributions of the ten priority pollutants were analyzed. The results showed that Chironomus tentans and Misgurnus anguillicaudatus are more sensitive to organochlorine pesticides, so they may be the indicator organisms of relational pesticides pollution and the tested organisms in water quality criteria study.
