Abstrakt: Metal concentrations in sediment and in whole tissue of the benthic polychaete Glycera longipinnis collected along the southwest coast of India were analysed. Relative seasonal accumulation of metals (Cu, Pb, Cr, Ni, Zn, Cd, Hg) was studied by categorising the habitat as less polluted or highly polluted based on metal contamination routed through industrial and urban sources. The metal content in tissues varied seasonally in the ranges, Cu: 2.21-27.08 μg·g-1, Pb: 0.06-4.92 μg·g-1, Cr: 1.73-29.20 μg·g-1, Ni: 1.60-4.61 μg·g-1, Zn: 14.72-82.30 μg·g-1, Cd: 0.04-1.38 μg·g-1and Hg: below decetable limits to 0.86 μg·g-1. Concentration of heavy metals was found to be high in the whole body of G. longipinnis pooled from the polluted transects. The results of this study suggest that G. longipinnis may act as a useful biological indicator for heavy metal pollution along the southwest coast of India. [ABSTRACT FROM AUTHOR]
