| description | Sediment sampling in the Straits of Johore revealed that the surface sediments collected at a jetty near a
mussel processing factory in Kg. Sg. Melayu had elevated Zn concentration in its first geochemical fraction;
namely, easily, freely, leachable or exchangeable (EFLE) and its total concentration. This total Zn level in the
sediment was comparable to the polluted sites on the west coast of Peninsular Malaysia. It was assumed that
the tap water, in which mussels had been boiled, might have contained high levels of Zn which would then be
released to the drainage system and finally emptied into the coastal waters where the jetty is located. In order
to confirm this point source of Zn contamination, a laboratory study was designed to ascertain if the boiled
mussels contained higher concentrations of metals compared to a control group. The laboratory results showed
that distilled water, in which fresh mussel tissues had been boiled for 15 minutes, possessed significantly (P <
0.05) higher levels of dissolved Zn. In addition, Zn concentrations in the total boiled soft tissues and boiled
shells of fresh mussel Perna viridis were significantly (P < 0.05) lower than the Zn levels before boiling, and
this finding evidently showed that Zn in the mussel tissues was remobilized and thus released to the water.
Therefore, these results supported the conclusion that the mussel processing factory at Kg. Sg. Melayu, which
used tap water to boil the mussels before shucking, was a point source of Zn contamination in this area in the
Straits of Johore. |
