| ecotoxicological bioassays of sediment leachates in a river bed flanked by decommissioned pesticide plants in nantong city, east china. | traditionally, the toxicity of river contaminants is analyzed chemically or physically through river bed sediments. the biotoxicity of polluted sediment leachates has not caught our attention. this study aims to overcome this deficiency through a battery of biotests which were conducted to monitor comprehensive toxicity of sediment leachates for the yaogang river in east jiangsu province of china, which is in close proximity to former pesticide plants. the general physical and chemical parameter ... | 2017 | 28191618 |
