    ABSTRACT: Vanadium and nickel are two important indicators of oil pollution. Lengthy exposure to these elements causes serious harmful effects in human health, different harsh allergies being examples. The accumulation of two heavy metals (Ni and V) in sediment and the soft and hard tissues of Saccostrea cucullata were analyzed at three sampling sites along the coast of Lengeh Port, Persian Gulf. Results indicated at all the sampling sites; the Ni levels in soft tissues (STs) were higher than in the shells (SHs) and sediments, whereas the V levels were higher in the sediments. In addition, meaningful relationship (r = 0.65; p < 0.05) was observed across Ni levels in ST of S. cucullata and sediment, while for V concentrations a strong relationship (r = 0.83; p < 0.01) was found in SH of S. cucullata and sediment. This indicates that ST and SH of oyster can be considered as a biomonitoring agent for Ni and V levels, in coastal waters, respectively. The exposure of the consumer is compared directly to minimal risk level and provisional maximum tolerable daily intake. Result indicated that levels of Ni and V were within the safety limits for human consumption.

    ABSTRACT: A total of 19 polymorphic microsatellite loci were used to analyze the levels of genetic variations for six geographical populations of green-lipped Perna viridis collected from the coastal waters of Peninsular Malaysia. In addition, the total soft tissues of all mussel populations were determined for heavy metals (Cd, Cu, Pb and Zn). F ST values revealed that all the six populations of P. viridis in Peninsular Malaysia were categorized as showing 'moderate genetic differentiation' according to the classification of Wright (1978). Cluster analysis revealed that three populations which were located in the western part of the Johor Causeway were clustered differently from the other three populations located in the eastern part. Hierarchical F-statistics and cluster analysis indicated that the Johor Causeway which blocked the free flow of the pelagic larvae swimmers of P. viridis and a distinct effect of heavy metal contamination on the Kg. Pasir Puteh population, were the two main causal agents for the genetic differentiation of the P. viridis populations investigated in this study. ABSTRAK Sejumlah 19 lokus mikrosatelit yang berpolimorfik telah digunakan untuk menganalisis tahap variasi genetik bagi enam populasi geografi kupang Perna viridis yang disampel dari persisiran pantai Semenanjung Malaysia. Keseluruhan tisu lembut daripada kesemua populasi juga ditentukan untuk logam berat (Cd, Cu, Pb dan Zn). Nilai F ST menunjukkan kesemua enam populasi P. viridis di Semenanjung Malaysia dikategorikan sebagai 'perbezaan genetik yang sederhana' mengikut klasifikasi Wright (1978). Analisis kluster menunjukkan bahawa tiga populasi yang berada di bahagian barat Tambak Johor telah diklusterkan berasingan daripada tiga lagi populasi yang berada di bahagian timur. F-statistik
