Abstract:

 


Mercury (Hg) and cadmium (Cd) are
non-essential trace elements that transfer through the trophic chain which
ultimately bio-accumulate and biomagnify
in the upper
trophic level.  The total Hg (THg) and Cd levels of the
muscle tissues of swordfish, Xiphias
gladius caught in three different
areas in the Indian Ocean around Sri
Lanka were determined.  THg and Cd levels were <0.07-4.30 mg/kg
and <0.006-0.180 mg/kg, (wet weight basis) respectively. Of the analyzed samples, 13.3% fish were over 1 mg/kg
for THg while not any single sample
exceeded 0.30 mg/kg for Cd which is EU, and
FDA action limits. The results indicate that the catching locations do not
govern the THg and Cd levels and it showed a weak positive relationship between
the length and weight of the fish.
