Abstract

The concentrations of heavy metals such as Cd, Fe, Zn and Ni were investigated in different types of bottled water samples (mineral and drinking) collected from Bentong, Pahang. The potential health risks of heavy metals to the local population were also studied. Heavy metals concentrations were analysed using atomic absorption spectrometer and compared with permissible limits set in Malaysian Food Regulation 1985 and World Health Organization Guideline. Heavy metals concentration was found in the order of with Fe>Zn>Cd>Ni. The concentration of Cd was higher than its respective permissible limits for both types of water, while Fe, Zn and Ni concentrations were observed within their respective limits. Health risk assessment such as Health Quotient (HQ) and Hazard Index (HI) were calculated. HI of the selected heavy metals in the drinking water was less than 1, indicating no health risk to the local people. Statistical analyses showed that geologic and anthropogenic activities were the possible sources of water contamination of heavy metals in the study area.
