Sanitary engineering Monitoring and assessing the quality of the coastal environment of Peninsular Malaysia on the effects of heavy metals pollution was evaluated using the estuarine organism as the main indicator. The assessment of environmental pollution in the western and eastern coasts of Peninsular Malaysia was done by analysing the contents of the heavy metals in the bivalves, sea waters and sediments. The cockles granosa) and mussels (Perna viridis) are choosen as the bivalves samples because they survive in the polluted area and are able to accumulate heavy metals with the bioconcentration factor reaching up to 10^, and they were abundantly cultured for human consumption. Twenty two sampling locations were choosen in the marine culture area and samplings were conducted twice to look for the prevailing trend. Thirty cockles and mussels with shell lengths of 30 to 42 mm and 8 to 10.3 cm respectively were gathered from these locations and used as specimens. Preconcentration of water samples was done by extraction with the so called APDCMIBK method. The bivalves samples were digested with a concentrated nitric acid and a mixture of concentrated nitric acid; fluoric acid and perchloric acid was used for sediment samples. Heavy metals analysed in this study were As, Cd, Cr, Cu, Pb, Se and Zn. The concentration of the heavy metals was measured by means of neutron activation analysis (NAA) and atomic absorption spectrofotometry (AAS) techniques. CRM of Marine Sediment Reference Material (BCSS), Nearshore Seawater Reference Materia! (CASS), Bovine Liver Reference Material (SRM 1577a) and Lobster Hepatopancreas (TORT-1) were used for quality assurance controls. Two correlation tests of the values of metals concentrations in bivalves with that in water-metals and with that in sediment-metais were performed. Based on these tests the potential use of the bivalves as pollution indicators were evaluated. Results from the APDC-MIBK method yielded a percentage recovery within the range of 83% to 107%. It was found that highly polluted areas by heavy metals were mainly concentrated within the west coast of the Peninsular. Cockles exhibited a good potential indicators for heavy metals such as As, Cu, Pb, Se and Zn, while mussels are suitable bio-indicators of Cd and Cr. 2000 Thesis http://eprints.utm.my/id/eprint/43436/ http://eprints.utm.my/id/eprint/43436/1/Nur%20Fajar%20Yanta%20M%20FS2000.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:61403 masters Universiti Teknologi Malaysia, Faculty of Science Faculty of Science
