| Abstract |
Although there is an increasing interest in heavy metals as pollutants in the marine environment, relatively little work has been done to determine the effect of such metals on marine organisms (Katzet al. 1971, 1972; Reish 1970, 1971, 1972; Selleck 1970, 1971). Most of these studies have dealt with lethal effects of copper and mercury on fouling organisms (Bryan 1971). Several investigators have reported heavy-metal effects on adult decapod crustaceans (Eisler 1971; Eisleret al. 1972; Raymont and Shields 1964; Vernberg and O'Hara 1972). There is, however, a paucity of information on the effects of cadmium on this group. The present study was undertaken to determine the toxicity of acute exposure of cadmium to the mud crab, Eurypanopeus depressus, as evidenced by mortality and by differential oxygen consumption occurring at non-lethal levels of this contaminant. E depressus was chosen for study because its estuarine habitat is likely to be polluted with heavy metals in the heavily industrialized areas of the Northeast. Cadmium was chosen as the test metal because of the growing awareness of its toxic properties, its persistent nature and its increasing occurrence in the environment. (U. S. Council on environmental quality 1971). |
