Abstract

Introduction: Heavy metal contamination in food sources are more concern among the communities because of the effects to the human health. Arsenic can be found naturally in the environment and cannot be destroyed or degraded. The occurrences of arsenic to the environment are from the rapid industrialization, agricultural and uncontrolled urbanization which directly pollute the river basin that will contaminate the aquatic organism. Aquatic organism especially fish is one of the major part of the human diet due to the high protein source content. Objective: A cross-sectional comparative study was conducted at Kampung Sedohok and Kampung Punjut in Kluang, Johor in order to determine the arsenic concentration in freshwater fish of polluted river of Sembrong and less polluted river of Kahang and health risk assessment among adults in the two areas. This study also aimed to determine the socio demographic information and the fish frequency intake among respondents of both areas. Methodology: A total of 30 respondents from each Kampung Sedohok and Kampung Punjut were randomly selected based on the inclusion criteria. A set of pre-tested questionnaire was used to obtain the socio demographic information, food frequency intake and health status of respondents. Three species (N=6) of freshwater fish were caught from the selected rivers by the local fisherman using net method which later analyzed for arsenic concentration using inductively Coupled Plasma Mass Spectrometry (ICP-MS). The health risk of respondents was indicated through the calculation of ADD, LADD, HQ and LCR. Results: All fresh water fish samples were detected with arsenic which range from 0.227 to 1.702 mg/kg and mean concentration of arsenic in freshwater fish for both areas do not exceeded the maximum concentration level stated in Ma]aysian Food Regulation 1985 (l mg/kg). There was no significant difference between the arsenic concentrations in fresh water fish of both areas. However, there was a significant difference in the health risk of the respondents of the two villages. The results also showed that there was a significant relationship between the fish frequency intake with health risk of both HQ and LCR of the respondents in Kampung Sedohok. Conclusion: Arsenic concentration in fresh water fish in polluted river of Sembrong showed slightly higher as compared with less polluted river of Kahang. Biological monitoring should be assessed for future improvement of the study in order to determine the actual burden of arsenic in human body of the respondents. Keywords: Arsenic, Fresh water Fish, ICP-MS, HQ, LCR, Health Risk Assessment
