Cadmium accumulation in the mummichog, Fundulus heteroclitus, adapted to various salinities
- National Research Institute of Fisheries Science, Kanagawa (Japan)
It is commonly known that salinity affects the toxicity of cadmium to aquatic biota. This toxicity has been shown to decrease with salinity in a variety of estuarine organisms. The effect of salinity on cadmium toxicity may be primarily due to greater complexation of free cadmium ions by chloride ions with increasing salinity. A high concentration of cadmium is found in the liver, kidney, intestine, and gills of fish after cadmium exposure. The kidney, intestine, and gills are important organs for osmotic regulation of fish and each function of these organics is altered by salinity of the medium in which fish live. This alteration in the kidney, intestine, and gills may influence cadmium accumulation. This study was conducted to examine cadmium accumulation in tissues of mummichog, Fundulus heteroclitus, adapted to various salinities and to evaluate the effects of salinity on cadmium accumulation from a physiological viewpoint. 13 refs., 2 tabs.
