Abstract: Investigations on distribution of heavy metals in water, sediment, plankton and fish (Mugil cephalus) was studied in Thane cyclone affected areas (Pondicherry, Cuddalore, Nagappattinam) and un-affected area (Mimisal). Accumulation rate of heavy metals was noticed in the order of Sediment > Water > Plankton > Fish. In water, the metal distribution order was found to be high in the order of Nagapattinam > Mimisal > Cuddalore > Pondicherry. Iron as dominant metal (28.91µg/l) at Mimisal and cadmium as least recorded metal (0.75µg/l). In sediments, the order was Cuddalore > Pondicherry > Nagappattinam > Mimisal. The zinc noticed as a dominant metal with 10.79µg/g at Cuddalore and cadmium minimum (0.59µg/g) found in Pondicherry. The area wise metal distribution in plankton were Pondicherry > Nagappattinam > Cuddalore > Mimisal with cadmium minimum (0.79µg/g) recorded at Pondicherry and zinc maximum (58.54µg/g) at Cuddalore. While for fish the order of metal accumulation was Mimisal > Pondicherry > Nagappattinam > Cuddalore with a maximum accumulation (23.02µg/g) of zinc at Mimisal and minimum (0.70µg/g) of cadmium at Cuddalore.
