Toxicology Reports
Urban Farm DB summary
This study examined trace element levels in Brassica pekinensis Lour. from urban gardening sites (Cecomaf and Lutendele) in Kinshasa, Democratic Republic of the Congo, and associated human health risks. Analysis showed that Cr, Cu, Cd, Pb, and Hg concentrations in samples from both sites exceeded FAO/WHO maximum permissible limits. Health risk assessments indicated that Estimated Daily Intake (EDI) values for Cd and Pb exceeded recommended limits, and Target Hazard Quotient (THQ) values exceeded 1 for most metals, suggesting potential non-carcinogenic risks.
