The Security Analysis of Trace Elements Accumulated in Fish Tissues with the Aquatic Eco-Environment from Fresh and Marine Waters
The pollution level of trace elements from nine types of fishes was study by ICP-AES techniques, and compare the pollution level differences of trace elements between fishes of fresh and marine waters. Assess the pollution risk of trace elements accumulated in fish tissues with the aquatic eco- environment from fresh and marine waters. The concentration changes of trace elements in fish tissues have some differences from freshwater fish tissues and marine water fish tissues, but the concentration distribution tendency of trace elements was similar. Mg elements had high concentration, Fe elements were rich in fish tissues, and Zn elements were in a relatively lower level in fish tissues. Their bioaccumulation levels with other trace elements, such as Mn, Cu, Ni, Co, Se, Cr, Mo, Sn and Al, were not considered as main contaminate elements in fish tissues, the pollution level of toxic elements like Cd, Pb and Hg in most fish tissues from this study demonstrated that the cultivation aquatic eco- environments of fresh water and marine water were relatively safe. But the potential pollutions of toxic elements in fish tissues, such as Cd, Pb, As and Hg should pay main attention.
