Markets in Selangor, Peninsular Malaysia]]>K.A. TaweelAbdulali Shuhaimi-OthmanM. AhmadA.K. 32012123Concentrations of cadmium (Cd), zinc (Zn), lead (Pb), nickel (Ni) and cobalt (Co) were measured in various organs (such as in liver, gill and muscle) of Tilapia fish (Oreochromis niloticus) which were collected from Serdang night market, Bangi night and wet markets and Kajang wet market, in Selangor, Peninsular Malaysia. The concentration of metals was measured by inductively-coupled plasma mass spectrometry (ICP-MS). The levels of metal varied as it depended on various tissues. Zinc was the dominant metal measured during this study. In general, results indicated that all studied heavy metals concentrations were significantly higher (p<0.05, two way ANOVA) in liver samples collected from all sites than gill and muscle, except for the zinc in fish liver from Serdang night market (41.87 μg g-1 dry weight (DW)) less than zinc in fish gill in the same market (55.72 μg g-1 DW). The highest Cd, Pb and Co concentration in fish liver were observed in Kajang wet market which is 0.44, 0.72 and 02.86 μg g-1 DW, respectively. Meanwhile, in fish gill, levels of Pb and Co in Serdang night market were the lowest among all sites which is 0.34 and 0.31 μg g-1 DW, while the highest in gill from Bangi wet market which is 0.63 and 0.41 μg g-1 DW, respectively. Cd, Zn, Pb and Co levels in fish muscle from Serdang night market were the lowest (0.02, 11.36, 0.10 and 0.25 μg g-1 DW, respectively), whereas the lowest Ni level was noted in fish muscle from Kajang wet market (03.84 μg g-1 DW). On the other hand, the highest Cd and Zn level were in Bangi wet market (0.03 and 16.72 μg g-1 dw, respectively). The results obtained in this study were compared with those reported in all other areas of earlier studies. All studied heavy metals levels are below the limits for fish proposed by World Health Organization and safe within the limits for human consumption in the edible part of studied fish.]]>Ahmad, A.K. and M.
