Abstract

Dissertation note: Project paper (B.S.(Env.& Occ.Health)) - Universiti Putra Malaysia, 2012.Introduction: Aluminium sulphate or alum is widely used in the purification of waste water as well as raw water from rivers, lakes and reservoirs. It is a flocculating agent with the capacity to coagulate and trap solid matter that may be floating in the water, such as algae and other organic and non-organic matter. The main objective in this study is to determine health risk assessment of exposure to aluminium levels in drinking water at Felda lenderak Selatan, Temerloh, Pahang. Methodology: This cross-sectional study was conducted in Felda lenderak Selatan, Temerloh, Pahang. To participate in this study, 95 respondents were selected. Two water samples were taken from each respondent's house. The water samples were preserved using nitric acid and then analysed using a Graphite Furnace Atomic Absorption Spectrophotometer (GF AAS) to determine aluminium levels in each water sample. Body weight of respondents was also measured using a Tanita Body Weight Scale and an interview session was conducted in order to gather information on the respondents' water daily intake and socio-demographic background. The health risk was calculated using equation based on the information given by the respondents. Results: The results showed that 84.2% of water samples exceeded the safe limit of National Drinking Water Quality Standard of Malaysia for aluminium is 0.2mg/L. The value of mean ± SD for aluminium levels in water samples was 0.3955 ± 0.2264 mg/L. The value of mean ± SD for pH level in water samples was 6.87 ± 0.2334. There was a significance difference between aluminium level and Malaysian Drinking Water Quality Standard (Z = 0.02, p<0.05). Pearson Correlation test showed that was a significant relationship between aluminium levels in water samples and pH level. After calculating health risk to aluminium exposure in drinking water, the health index (HI) value is less than 1, showing that there was no risk or the risk was acceptable. Keywords: Risk assessment, aluminium, human, drinking tap water, Felda Jenderak Selatan.
