Abstract

In this study is to assess heavy metal contamination (Cd, Cu, Pb, Zn) in white shrimp (Litopenaeus Vannamei) along coastal of Kelantan and its potential health risk. Three location were selected to carry out this study which are Tok Bali, Tumpat and Kuala Besar. The method that used for this study is wet digestion before analyse using Atomic Absorption Spectroscopy (AAS). The result show mean concentration of the metals Pb, Zn and Cu from in shrimp from Tok Bali is 0.1750, 34.5650, 14.2050 mg/kg respectively. Concurrently, Sample Location Tumpat’s Pb, Zn and Cu mean concentrations are 0.2078, 45.6350 and 13.4300 mg/kg and last for Kuala Besar’s Pb, Zn and Cu mean concentration are 0.2295, 22.3000 and 11.7000 mg/kg. The p-value of Pb and Zn are less than 0.05 which means that the test is significant and null hypothesis is rejected. It can described that the differences in means of Pb and Zn between Tok Bali, Tumpat and Kuala Besar has significant difference. On the contrary, p-value for one of the variable (heavy metal Cu) is P > 0.05 which is 0.097. As the pvalue exceeds 0.05, the test is not significant and null hypothesis is accepted which indicating that the data is normal. For health risk assessment (HRA), estimated daily intake (EDI), target hazard quotient (THQ) was calculated as for non-carcinogenic risk level which are Zn and Cu due to pollutant exposure. Target Hazard Quotient (THQ) values for Tok Bali, Tumpat and Kuala Besar were in same order which is Cu>Zn. CR values follow the order for Pb are Kuala Besar > Tumpat > Tok Bali. The total CR of Pb of each location is lower than range 10-⁴ to 10-⁶ of the USEPA unacceptable level.
