Abstract

Project paper (B.S.(Environmental & Occupational Health)) – Universiti Putra Malaysia, 2014. Introduction: The nitrate exposure in groundwater especially in agricultural areas has become a major public health issue. Methaemoglobinemia is the most common disease that is related to nitrate exposure. Objective: This cross-sectional study was conducted in Pasir Puteh, Kelantan with an aim to determine the nitrate exposure levels in groundwater and to perform health risk assessment among respondents at the respective areas. Methodology: Seventy (70) respondents were selected in this study based on the inclusive and exclusive criteria. The groundwater samples were taken from each respondent's well, and was analyzed with a Hach DRl2500 Spectrophotometer to determine nitrate levels. Questionnaires were used to determine respondents, water daily intake, socio-demographic background and status of water supply quality. The body weight of respondents was measured using a Seca Body Weight Scale. The health risk assessment was calculated using the Chronic Daily Intake (CDI) and Hazard Index (HI). Results: Nitrate level in this study was below Concentration Limit of National Drinking Water Quality Standard Malaysia (NDWQS) (<10mg/L) with the mean ± SD of 2.1 1 ± 1.24 mg/L and ranged between 0.20 to 5.20mg/L. The highest mean ± SD was determined in Kampung Batu Sebutir (2.28±0.9 mg/L) while the lowest mean ± SD determined in Kampung Panggong (1.98 ± 1.21 mg/L). The mean + SD for CDI was from nitrate were in acceptable range. Conclusion: As far as nitrate exposures are concern, the groundwater would not cause non-carcinogenic health effect to those who use it for daily purpose Keywords: Nitrate, groundwater, National Drinking Water Quality Standard Malaysia, maximum concentration limit, chronic daily intake, hazard index, Pasir Puteh.
