Trace metal contamination using polymesola expansa (BIVALVE) as bio-indicator in Kelantan River, Malaysia

Abstract

Human are easily contact with natural resources and some of marine natural organisms were being consume by human as daily diet. One example of marine organism that become favourite to human is bivalve and easily being captured in upper layer of mud in mangrove or semi-mangrove area. However, the scientists had proven that the bivalve is the organism that the bivalve is significantly inhale or 'consume' whatever the food pass by through the water column. Due to this behaviour, the safety of the consumption of bivalve or marine organisms are argued by people as same as the researcher from the result of unknown sources of food that taken by the bivalve. As the bivalve is acceptable for doing metal toxicity analysis, it is used to know the pollution status of the area of study.
