Abstract

Summary: Introduction: A cross-sectional study was conducted in Felda Palong, Negeri Sembilan. Objective: The main objective in this study was to determine health risk of exposure to aluminium levels in drinking water at Felda Palong, Negeri Sembilan. Method: A total of 60 respondents were selected to participate in this study. Two water samples were taken from each respondent's house, and then, was preserved using 0.5 ml of concentrated nitric acid (69%) and analysed using Graphite Furnace Atomic Absorption Spectrometer (GFAAS). Water pH level was measured by using a Lamotte Tracer Orp Pocketester. Besides that, body weight of respondent's also been measured by using a Seca Body Weight Scale. The interviewed session also had been done in order to know the respondents daily water intake, socio-demographic background and status of water quality supply. The health risk was calculated for each respondent using equation of Chronic Daily Intake and Hazard Index based on the information given by respondents. Results: Results showed that 53% of water samples exceeded the upper safe limit of National Standard for Drinking Water Quality Malaysia (>0.2mg/L). The value of mean (SD) for aluminium levels in water samples was 0.292 (0.217) mg/L. The value of mean (SD) for pH level in water samples was 6.865 (0.429). There were significance difference between aluminium level and Malaysian Drinking Water Quality Standard with (z = 0.02, p<O.OOI). Pearson Correlation test showed that was significant relationship between aluminium levels in water samples and pH level. Hazard Index (HI) calculation showed that all respondents had "HI" of less than 1. Conclusion: The calculation of health risk of aluminium exposure in drinking water found that the risk was in acceptable level. Keywords: Aluminium, drinking water, health risk assessment, hazard index (HI), pH Level, Felda Palong
