Description 92-95
Levels of
Cu, Zn, Cd, Pb and Ni in shrimps and crabs from Thane-Bassein creek system were
evaluated for a period of one year and reported as baseline for future
monitoring of this vital ecosystem. The pattern of concentration was in the
order of Zn>Cu>Cd>Ni>Pb. In shrimps maximum level of Cu (av 41.3
ppm dry wt) and Zn (av. 164 ppm dry wt) were observed respectively in Metapenaeus
brevicornis from Thane creek and Exopalaemon stylifera from Bassein
creek. The crabs, Scyllaserrata from Thane creek showed maximum
concentration for Cu (73 ppm dry wt) and Zn (376 ppm dry wt). Cd, Pb and Ni

contributed very little to the
percentage contribution of the metals estimated. In general the concentration
of metals in shrimps and crabs were 2-11 times higher than that reported for Bombay harbour. However,
the levels of these metals have not exceeded the limit prescribed for consumption.
