Abstract

Fish is important in the balance of nature and in the food chain, as it is a main sources of protein for human consumption. Rapid industrialized agriculture practices has increased the usage of pesticides in the paddy field which resulting in increased of heavy metals in fish. Consumption of fish contaminated with heavy 1netals by humans cause chronic health impacts and can be toxic to human body when exceeded the permitted limits. The objective of this study is to determine the concentration of Pb, Cd and As in Anabas testudineus and to assess the dietary health risk among respondents who consumed Anabas testudineus from Sabak Bemam. A set of questionnaire was used to obtain information on socio-demographic, health status and frequency of fish intake. The heavy metals were analyzed by using Inductively Coupled Plasma Mass Spectrometry (ICPMS) to determine the heavy metals concentration contented in the flesh muscle of Anabas testudineus. Hazard Quotient (HQ) and Lifetime Cancer Risk (LCR) were used to estimate the non-carcinogenic and carcinogenic effects, respectively. The concentration of As (0.00597 mg/kg) and Pb (0.05117 mg/kg) were found in the Anabas Testudines. When compare to the Food Regulation 1985, the concentration of heavy metals are not exceeded the permitted level. Both the HQ of As and Pb for male and female showed lower than one. Whereas, the LCR of As showed the result with an unacceptable range of lifetime risk. Based on HQ estimation, no adverse health effects are expected from the dietary exposure to Pb and As in the Anabas testudineus. The cancer risk is likely to happen after estimating the lifetime cancer risk of arsenic intake from Anabas testudineus. Even at a low amount of heavy metals detected, but people still expose to these heavy metals via consumption of Anabas testudineus. Regular monitoring is needed to ensure the concentration of heavy metals are within the safe limit. Keywords: heavy metals, Anabas testudineus, dietary health risk assessment, paddy field.
