This study was conducted to identify the risks of heavy metal contamination in urban and peri-urban cropping systems in Sierra Leone. Soil and plant samples were collected from 72 sites in Freetown and Bo and analyzed for Zn, Cu, Cr, Ni, Pb, and Cd. Heavy metals were detected across all sites, and some mild risk of cadmium toxicity was observed in densely populated areas of Freetown, though this was not reflected in plant uptake of cadmium.
