Description Trace metals in the muscle tissue of nine species of commercially important marine fishes collected from Port
Blair (Andamans) and at Kochi (Kerala, southwest coast) were compared to study the level of bioaccumulation.
Levels (pg per g dry weight) of dd, Cu, Fe, Mn, Ni, Pb and Zn were estimated using ASS. Except Mn and
Zn, all other metals were below detection levels in the samples collected from Port Blair. Compared to the
same species and similar size from Kochi, Mn in Saurida turnbil (17.85 pg/g) and Zn in Epinephelus tauvina
(97.1 lpg/g) from Port Blair were at higher levels. Samples from Kochi recorded accumulation of 1.42 pgl
g Cd and 271pglg Fe in Rastrelliger kanagurta, 11.3 pglg Cu in Sardinella gibbosa and 83.3 pglg Pb in
S. rurnbil. Baring Pb, the bioaccumulation of all other metals in the fish samples was within the WHO
prescribed safe limits. Compared to the levels of Pb in sediment (59.76 pglg) and water (1.8 pgll) from Port
Blair, lower value was recorded in the sediment (7.5 pg/g) and higher values in water (2.17pg/l) from Kochi.
Significant correlation could not be established between the metal levels of Sediment and water samples
neither from Port Blair nor Kochi. Significant correlation to O.Olleve1 could be established positively
between water and Liza parsia, E. tauvina and S. longiceps as well as Pentaprion longimanus and R.
kanagurta with sediment from Kochi.
