Abstract

Introduction: Battery factory in Kg Jenjarom operated smelting process which leads to the release of lead (Pb) to the environment via air dispersion and discharging into the waterway. Other harmful heavy metals such as arsenic (As), nickel (Ni), cadmium (Cd) and chromium (Cr) also can coexist in the environment which might cause serious health problem to the community. Objectives: The aim of this study is to determine the heavy metals concentrations in air, soil and water and to predict the health risk from heavy metals exposure. Methodology: Environmental samples were taken at three different distances from the factory: 500 m, 1.0 km and 1.5 km. Air samples were collected by using personal air sampling pump, the topsoil samples were collected using scoop and High-Density Polyethylene (HDPE) bottles were used to collect the sample of surface water. The analyses were carried out in the laboratory using Inductive Coupled Plasma Mass Spectroscopy (ICPMS). Results: The results showed that the air Cr concentrations (1.627) were high in air and exceeded the Air Quality Standard by Agency for Toxic Substances and Disease (ATSDR). While for soil and water samples, Pb concentrations (0.17) were high in the topsoil and exceeded the Standard of Dutch Target for soil while the heavy metals in surface water did not exceed the National Water Quality Index for Malaysia Class iv (Irrigation). Based on Health Risk Assessment (HRA), Hazard Quotient (HQ) for Ni (8.82) and Cr (15.6) in air were more than one. Lifetime Cancer Risk (LCR) for air Cr was 2.34 x 10-2 and exceeded the acceptable lifetime cancer Risk (1 x 10-6 to 1 x 10-4). However, for soil and water, all heavy metals had HQ of less than 1 and LCR in an acceptable range. Conclusion: These results, indicated that exposure to air Ni and Cr might result in non-carcinogenic acute and chronic health effects for the community, while exposure to air Cr could lead to cancer. Keywords: Heavy metals, Environmental samples, Health risk assessment, Non-carcinogenic health risk, Carcinogenic health risk.
