Consumption Patterns of Milkfish (Chanos chanos) and Lead (Pb) Exposure on The Coastal Community of Tarakan City

Abstract

Lead (Pb) in marine waters has a high impact on marine life related to its contamination. This contamination also affects the public health status of the people as the permanent consumer which has some noncarcinogenic or carcinogenic effects on the human body. This study aims to analyze risk management of potential non-carcinogen and carcinogen Pb exposure as the consequences of the milkfish (C. chanos) consumption using the environmental health risk assessment (EHRA) method on Tarakan coastal population with a total of 77 participants. inductive coupled plasma mass spectrometry (ICP-MS) was used to identify the concentrations of Pb in the fish. The result shows Pb concentrations in the meat of the milkfish (C. chanos) was 0.003-0.046 mg/kg. The Risk Quotient (RQ) value of Pb in the milkfish (C. chanos) was 60(78%) respondents at risk and 17(22%) were not at risk of non-carcinogenic potential, while the value for the carcinogenic potential of Excess Cancer Risk (ECR) of milkfish showed 77(100%) of respondents at risk due to its consumption. The contamination control system in Tarakan coastal area is highly necessary, domestic waste management should be socialized to every household particularly before it disposed directly to marine water, and also minimalizing of using an-organic fertilizer in fishpond aquaculture is also highly recommended
