Abstract
Heavy metals, once thought to be insignificant as pollutants, has
become one of the worst pollutants, following the outbreak of Minamata
disease in Japan, as a result of Hg poisoning. Since then, various studies
have been conducted on the effects of various heavy metals on the
ecosystem. These research works led to the categorization of heavy
metals as "black listed" and "grey listed" elements, and strict standards
were laid down for the discharge of the same in the ecosystem (Phillips
and Rainbow, 1997). Marine sediments can be a sensitive indicator for
monitoring contaminants in the marine environment (Larsen and Jensen,
1989). Mumbai is a large metropolis on the west coast of India and forms
the hub of important industrial activities. All the effluents generated in the
city reaches the coastal waters. Studies on different aspects of heavy metal
pollution on Mumbai coast have been conducted by several workers
(Matkar etal.. 1981; Patel et al., 1985; Gajbhiye, et al. 1985; Patel and
Chandy, 1988; Qasim, et al. 1988; Kumari et al., 1992; Nair and Kumari,
1993). However, information on current status of pollution would be useful
in the coastal regions like Mumbai, which are under tremendous population
and industrial pressure. The present study was carried out to understand
the spatial and temporal variations of heavy metals such as Cu, Zn, Pb,
Fe and Mn in the sediments of Mumbai coast.
