AN EVIDENCE OF PB REDISTRIBUTION IN THE DIFFERENT SOFT TISSUES OF TELESCOPILIM TELESCOPILIM COLLECTED FROM A PB-CONTAMINATED INTERTIDAL SITEC.K. YAP AND A. NOORHAIDAHAbstract The different soft tissues (foot, cephalic tentacle, mantle, muscle, gill, digestive caecum and remaining soft tissues) of the mud-flat snail TeleSCOpiUM telescopium were determined in snails from 5 geographical sites in the south western intertidal area of Peninsular Malaysia. This work firstly intended to investigate the Pb distribution in the different soft tissues of intertidal snail T. telescopium and interestingly, it is also found that Pb redistribution was evidenced in digestive caecum in the polluted population collected from Kuala Sg. Ayam. The high Pb contamination and bioavailability of Pb indicated by the different soft tissue of T. telescopium from Kuala Sg. Ayam population was also complemented by the_ significantly (P< 0.05) higher Pb level found in sediment samples. Therefore, Pb redistribution in the different soft tissues of T. telescopium be used as a potential indicator of bioavailability and contamination of Pb in the tropical intertidal area.
