Abstract

Background: Heavy metal such as Cd, Pb, As and Cr contamination of the coastal environment was a major problem and need a serious attention. Heavy metals are commonly found in the environment due to natural occurrence or as a result of anthropogenic activities. This situation has lead to the contamination of marine organisms such as acetes shrimp (udang geragau), which this shrimp be a main ingredient of cencaluk production. The aim of this study was to determine the Cd, Pb, As and Cr concentration in cencaluk and to estimate the health risk due to consuming contaminated cencaluk among adult residents in Pantai Puteri, Melaka. Methodology: Samples of cencaluk were purchase from the homemade cencaluk manufacturer in the study area and Small Medium Industries (SMI). The determination of heavy metal was performed by using ICP-MS. A total of 162 of Pantai Puteri residents were selected as respondents. A set of questionnaire consist of five part which include the socio-demographic, acute and chronic heavy metal poisoning sign, body mass index, food frequency intake and sources of other exposure were used to obtain data from respondents. The health risk assessment of the respondents was indicated by Average Daily Dose (ADD) and Hazard Quotient (HQ). Results: It was found that all 15 cencaluk samples were contaminated with heavy metal Cd, Pb, As and Cr which exceeded the maximum Cd concentration level stated in Malaysian Food Regulation 1985 (1 mg/kg) except for Cd. The health risk assessment for As and Cr showed not acceptable risk for HQ. There was significant relationship between frequencies of cencaluk intake with the sign of Cd, Pb, As and Cr poisoning. Conclusion: It is concluded that the cencaluk samples were contaminated with heavy metals which certain heavy metals exceed the guideline recormnendation limit and may cause health risk to the respondents. It is recorrunended that the respondents undergo biological monitoring in order to determine the actual Cd, Pb, As and Cr exposure and associate it with health risk encountered by respondents. Keywords : Cencaluk. Acetes shrimp, Health Risk Assessment, HQ
