Factors influencing cadmium accumulation and its toxicity to marine organisms
Numerous experiments that investigated the factors affecting cadmium accumulation and cadmium toxicity in marine organisms are discussed. Laboratory tests demonstrated that the toxicity of cadmium to estuarine shrimp and larval fish is related to salinity. As the chloride concentration in water increases, the concentration of free cadmium ions decreases. Experiments that measured cadmium uptake by shrimp showed that the accumulation of cadmium and the chloride concentration are inversely related. Investigations have been undertaken to determine the physiological effects of cadmium on the respiration rate of excised oyster gill tissue. An experiment that determined the capacity of marine organisms to detoxify accumulated cadmium is described. (9 graphs, 34 references, 1 table)
