The main study in this paper included as follows : the content and distribution of heavy metals in sediments and benthic organisms from the sewage stream in guangzhou city ; the acute toxicity and joint toxicity of mercury and selenium to swordtail fish ( xiphophorus helleri ) ; the damage of mercury to the indexes of antioxidant system in the gills and livers in swordtail ( including the measurement of the activities of total antioxidative capacity [ t ~ aoc ], superoxide dismutase [ sod ], glutathione peroxidase [ gsh - px ] and the concentration of malondiald - ehyde [ mda ] ) and the relief effects of selenium on it, as well as the physiological damage of mercury on the tissues, namely : the antagonistic effect of na + - k + ~ atpase activity on the tissues between selenite and mercury, and the ultrastructural damage under the exposure of mercury
