Pb Pollution on Water and Environmental Health Risk in Women Who Live in Belawan Coastal Area

Abstract

Medan Belawan region is an industrial area, the port and residential areas. The east coast of North Sumatera waters includes in heavily polluted waters by domestic wastes, industrial wastes, and agricultural wastes including ponds wastes. Based on several researches Parameter of Pb in seawater increased significantly. Bore wells of resident were contaminated by Pb and sea water intrusion occurs. Housewife is a subject that is assumed consumes more drinking water and has a tendency at risk due to exposure of Pb in drinking water. This study aims to analyze the environmental health risk assessment (EHRA) on housewives who live in coastal Bagan Deli Belawan village.This study is a survey with 49 mothers as subjects sample and the numbers of sample objects are 49 Bore wells. The method of data analysis was using analysis of environmental health risks formula. The formula calculate. The results from 49 samples Bore wells are on the average the Pb concentration was 0.006 mg / L, the highest Pb concentration was 0.026 mg / L (NAV = 0.015 mg / L). The amount of the highest consumption was 4 L / day. Based on the data analysis, there are 10 Bore wells with Pb exceeded environmental quality standards. Based on the calculation of the environmental health risk analysis obtained RQ <1 (the average RQ = 0:02), ECR value <E-4 means concentrations of Pb not cause a carcinogenic risk for housewives yet. However the environmental management is necessary so heavy metal pollution on resident wells can be overcome.
