ASSESSING LEAD CONCENTRATIONS IN LEAFY VEGETABLES IN SELECTED PRIVATE MARKETS IN METRO MANILA, PHILIPPINES

Heavy metal contamination of vegetables poses a threat to consumers' welfare. This study aims to determine the lead concentrations in leafy vegetables sold in selected markets in Metro Manila, Philippines. About five randomly sampled leafy vegetables obtained from two private markets in Metro Manila were examined for their lead concentrations. All vegetables bought in the private markets had lead concentrations. Most leafy vegetables obtained had low lead concentrations. Significant differences on the lead concentrations in all leafy vegetables obtained in the different markets were found (p < 0.05). The contamination of vegetables with lead in elevated levels may have potential health hazards to consumers. Proper washing of vegetables before consumption may help reduce the health risk.
