Abstract

Introduction: Malaysia is home for variety species of freshwater fish, however, freshwater area becoming polluted with chromium (Cr) due to development of many industries. This study investigated the level of Cr in freshwater fish included Lampam Jawa (Puntius gonionotus), Jelawat (Leptobarbos hoevenii) and Terubol (Osteochilus hasseltii). Objectives: This study is a cross sectional comparative that determined the chromium concentration in freshwater fish and health risk assessment among adults in two areas. Methodology: Total of 30 respondents from each village were recruited to compare Cr concentration in fish from polluted area (Sembrong River) and less polluted area (Kahang River.) Three species (N=6) were collected that caught by local fisherman. Cr were extracted from freshwater fish using wet acid digestion. Inductively Coupled Plasma (ICP-MS) was used to evaluate the level of chromium in freshwater fish. Health risk assessment (HRA) was determined by a set of questionnaire consisted of socio demography data, health Information, anthropometry data, food frequency intake and other sources of chromium. Hazard Quotient (HQ) and Lifetime Cancer Risk (LCR) were calculated as indicator for HRA. Results: Cr was detected in each sample with the range of 0.44 mg/kg to 25.26 mg/kg. The mean Cr concentration in fish at Kampung Sedohok was 8.77mg/kg which was 4 times higher than Kampung Punjut (2.59mg/kg). The highest Cr concentration was in Terbol (Osteochilushasseltii) from Kampung Sedohok. The result showed that the mean Cr concentration in freshwater fish was above the permissible level stipulated by FAG. There is a significant relationship between frequency of freshwater fish intake and HQ for Kampung Sedohok. Conclusion: This study indicated that Malaysian freshwater fish are contaminated with Cr. A strong significant relationship was found between fish consumption and HRA. Further study need to be conducted to measure Cr concentration in human body that constitutes a risk for human health. Diets high in simple sugars would increase the urinary excretion of chromium. This help in reducing the body burden of Cr in the body. Keywords: Freshwater fish, Cr, ICP-MS, Hazard Quotient (HQ), BRA
