Using cd, cu, zn and cr as experimental toxicants and crucian as experimental creature, we employed the environmental biotechniques ( flame atomic absorption spectrophotometry, the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure. through which, we intended to fully and systemically study the toxic influence of heavy metals to fish, and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual, organ, tissue, cell and molecule. thus we tried to provide scientific evidence to establish preventative management measures, avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time
