There is no evidence that cadmium is biologically essential, but its toxicity to organisms is well known. The so-called Itai-Itai disease in Japan, characterized by osteomalacia and renal tubular malfunction, has been attributed to cadmium poisoning in irrigation water. The degree of contamination in aquatic environments is frequently assessed by comparing contaminant concentrations in associated biota. Bioaccumulation, however, is influenced by environmental factors other than the degree of contamination, environmental factors such as salinity, temperature and pH. The use of cadmium in the electroplating industry in Taiwan is intensive, but the wastewater used in this industry is seldom treated and has been a serious problem. The Japanese eel (Anguilla japonica) is an important freshwater aquacultural fish in Taiwan; thus, it is important to know the accumulation and elimination of cadmium in the Japanese eel due to cadmium-polluted water at various temperatures in order to protect eel resources as well as human health. 18 refs., 3 figs., 1 tab.
