P. Sukasem et Ms. Tabucanon, MONITORING HEAVY-METALS IN THE GULF OF THAILAND USING MUSSEL WATCH APPROACH, Science of the total environment, 140, 1993, pp. 297-305
Concentration of zinc, manganese, copper, chromium, nickel and cadmium
were determined in the whole soft parts of the mussel, Perna viridis,
collected along the coast of the Gulf of Thailand. Mussels were sampl
ed from 10 locations, during 1989-1990, following an earlier study in
1986. The trends of accumulations of investigated metals in the mussel
were not higher than the previous study, except for the concentration
of manganese and nickel. The levels of manganese and nickel in the mu
ssel in 1989 and in 1990 were much higher than those reported previous
ly for 1986. In addition, the level of cadmium, manganese and chromium
in mussels from the western coast of the Gulf was higher than that fr
om the other parts of the Gulf. However, the levels of such metals wer
e within the acceptable limits with respect to the public health stand
ards.
