Abstract

The levels of heavy metals such as copper (Cu), cadmium (Cd), chromium (Cr) and zinc (Zn) in the sediment and associated macrobenthos were monitored during pre and post monsoon seasons from October 1997 to May 1998 in thecoastal waters off Mangalore receiving industrial effluents. The concentration of Cu in the sediment varied from non detectable level to 108.80 ppm, Cd from non detectable level to 4.56 ppm, Cr from non detectable level to 206.00 ppmand Zn from 1.00 to 2001.00 ppm, while in macrobenthos, the concentrations were as high as 228.80 ppm, 14.90 ppm, 177.00 ppm and 1630.00 ppm respectively. Except Zn, other heavy metal levels in the sediment were higher in deeperstations as well as in post monsoon season. Cu and Cd concentrations were higher in biological tissue than the sediment indicating greater capacity of bioaccumulation
