Seawater samples
collected in the vicinity of MAPS (Madras Atomic Power Station) from 17
stations covering an area of 4 km2 were analysed for distribution of
heavy metals viz. iron, copper, cadmium and mercury. Mercury was analysed by
cold vapor Atomic Absorption Spectrometry (AAS) and the other heavy metals by
Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). Water
samples were found to have heavy metals such as Fe (26-85 mg l-1),
Cu (0.05-5.1mgl-1; Cd (0.5-1.7 mg l-1) and Hg (0.03-1.5 mg l-1).
Samples from the power plant cooling system and condenser outfall were
specifically analysed for copper and primary production. Copper concentrations
were in the range 1 – 2.2 mg l-1. Primary productivity was low
on passing through the power plant cooling circuit. However, it was found to
recover once the effluent mixed with the ambient sea. Present study infers that
heavy metal concentrations in the vicinity of the power station outfall are
comparable to unpolluted pelagic waters of the Bay.
