Rare earth compounds are widely used in industry and agriculture ,which may have an impact on the environment of water. In this paper, using laboratory immersion tests of acute toxicity of lanthanum chloride seven hydrate on noninfectious Oncomelania hupensis, regarding the snail movement to suppress as the EC value, the results showed:EC50=152.14mg/L, LC50=160.92mg/L (72h, 20℃). The noninfectious snails O.hupensis are excellent compounds toxicity test animal.
