| Abstract: | Toxicity of river water, interstitial water and sediment collected from Lean river in June 1993 and October 1994 were assayed by using light emission inhibition of P. phos-phoreum sp. T3 and V. qinghaiensis sp. Q67, growth inhibition of C. valgaris and S. obliqnus, as well as acute and chronic toxicity on D. magna. The results showed that there were strong toxicity in 40, 50 and 159 km down stream of the river and that the toxicity comes mainly from discharges of Dexin copper mine , discharges of mines and smelters along Jishui river. as well as release of sediment-bound metals when approaching to Poyang lake. |
