Abstract

Dissolved mercury and total chlorophyll concentrations from the surface waters between 16Wand 20"30'N (upto 1000 m depth zone) were estimated from the samples collected onboard FORV Sagar Sampada during October, 1988. The dissolved mercury levels showed an average value of 1.04 pg/l, ranging from 0.3 to 2.2 pg/l and the total chlorophyll to 0.423mg/m3 varying from 0.120 to 1.149 mg/m3. Mercury concentrations in the presently reported areas is within the tolerance limit but lie well above the risk concentration levels. The high levels of mercury observed can be attributed to the discharge from the major rivers adjoining the coast.
