Abstract

Summary: Introduction: Arsenic (As) is a naturally occurring element widely distributed in the earth's crust and human are affected by exposure to arsenic in food chain and drinking water. Objective: A cross-sectional study was conducted at Kampung Pantai Rombang (PR) and Kampung Pinang (KP), Melaka to determine the arsenic concentration in shrimp paste and perform health risk assessment estimated among respondent. This study also aimed to determine the relationship between shrimp paste frequency intake with health risk which indicated by Hazard Quotient (HQ) and Lifetime Cancer Risk (LCR) and to determine relationship between shrimp paste frequency intake and health symptoms of respondents. Material & Methodology: A total of 151 respondents were randomly selected based on inclusion criteria. A set of pre-tested questionnaire was used to obtain socio-demographic information and to predict the health risk faced by respondents which indicated by the Average Daily Dose (ADD), Lifetime Average Daily Dose (LADD), frequency of shrimp paste intake and health symptoms experienced by respondents. Two duplicates of shrimp paste samples were purchased from each village. The arsenic concentration was analyzed by using Inductive Couple Plasma Mass Spectrophotometer (ICP-MS). Results: All shrimp paste samples contained As which exceeded the maximum As concentration level stated in Malaysia Food Regulation 1985(1 mg/kg). The finding on LCR and HQ demonstrated that all respondents encountered acceptable risk towards carcinogenic and noncarcinogenic health risk. On the other hand, the result also depicted that there were no significant relationship between the shrimp paste frequency intake with LCR and HQ. The result also exhibits no significant association between shrimp paste frequency intake with acute and chronic As poisoning signs. Conclusion: As was detected in all shrimp paste samples at concentration which exceeded the permitted As concentration in food. There was unlikely potential adverse health effects from arsenic intake in shrimp paste in this study. It is recommended that the respondents undergo biological monitoring in order to determine the actual As exposure and associate it with health risk encountered by the study population. Key words: Arsenic, Shrimp paste, Health Risk Assessment, LADD, ADD, HQ, LCR
