摘要：Aquatic ecosystem is very sensitive to heavy metals and the matter has received considerable concern due to their toxicity and bioaccumulation. The health implication due to Mercury exposure through food chain is a serious matter of concern for human health. In the present study bioaccumulation of Mercury from Catla catla species collected from four different collection sites of Shivnath River of Chhattisgarh, India was analyzed in various tissue samples viz., muscle, gill and liver by atomic absorption spectrophotometric method. In all tissue samples Mercury was reported significantly higher (F=<0.05 %P) than the recommended permissible limit of European commission. It was reported that muscles having maximum tendency of bioaccumulation followed by gills and liver and maximum bioaccumulation was reported in the month of October-March. The study is significant with respect to the food chain of population from catchment area.
