The effects of cadmium metal on the bioaccumulation and histopathology of macrobrachium rosenbergii post larvae
Heavy metals are the most serious pollutants of great environmental concern because they are degradable and toxic. Cadmium is an essential trace nutrient for humans and animals. The deficiency of Cd leads to increase the physiological demand in aquaculture. The effect of cadmium metal on the bioaccu...
