BIOACCUMULATION OF NAPHTHALENE IN A FEW TISSUES OF FRESH WATER FISH Rasbora daniconius

Chronic exposure of the freshwater fish Rasbora daniconius to Naphthalene showed bioaccumulation in varying concentrations in the gill, liver, intestine and kidney tissues. The extent of bioaccumulation of Naphthalene was assessed with the help of GCMS in terms of wet weight of tissue. Maximum bioaccumulation of Naphthalene was found in intestine tissue, to the extent of 0.33 μg g-1 wet weight of tissue, followed by kidney, gills and liver. Bioaccumulation found in the tissues of fish indicates the possibility of biomagnifications across various trophic levels of food chain and a possible ultimate effect upon human health.
