The importance of shrimps as a food is primarily because of its
unmatched nutritional qualities. Metapenaeus dobsoni (Miers, 1878) is
commercially important seafood species.However rapid industrialization and
urbanization have caused pollution of aquatic ecosystems to a great extent,
which could lead to bioaccumulation of heavy metals in tissues of shrimp.
Consumption of such shrimps may lead to the harmful effectson human health. The
present study aimed to determine the extent of bioaccumulation of heavy metals
(Zn, Pb, Cd and Ni) in hepatopancreas, gill, carapace, and muscle of
Metapenaeus dobsoni from the Uran coast, Raigad district, Maharashtra using
Inductively Coupled Plasma Atomic Emission Spectrophotometer. Zinc level in
hepatopancreas, muscle, carapace and gill was33.5ppm, 23.537 ppm, 9.697 ppm and
23.1975 ppm respectively.Lead level in hepatopancreas, muscle, carapace and
gill was 0.25ppm, 0.0926ppm,0.11 ppm and 0.1885 ppmrespectively. Nickel level
in the hepatopancreas, muscle, carapace and gill was 0.2396 ppm,
0.041ppm,0.0406ppm and 0.0675ppm respectively.Cadmium level in hepatopancreas,
muscle, carapace and gill was0.0256 ppm, 0.0106ppm,nil and 0.017 ppm
respectively. The study showed that these metals were present in the samples at
different levels but within the permissible limits. - See more at:
