This study investigated toxic metal and PAH contamination in rooftop soils and vegetables (red amaranth, spinach) in urban and peri-urban Bangladesh. Urban rooftop soil and vegetables were highly contaminated with toxic metals and PAHs compared to peri-urban samples. Lead (Pb) and cadmium (Cd) concentrations in urban vegetables exceeded safe limits. However, health risk indices indicated that the levels of toxic metals and PAHs in urban rooftop vegetables would not pose carcinogenic or non-carcinogenic health risks for adults and children, deeming them safe for consumption.

A study conducted in the Kasungami district of Lubumbashi, Democratic Republic of Congo, investigated the link between the use of polluted waters in urban agriculture and heavy metal contamination in soil and cultivated vegetables (amaranths, broccolis). Physicochemical and mineral analyses of water, soil, and plant samples revealed that heavy metals, except cobalt, were present in the water used for urban agriculture at concentrations below quality standards, but the soil contained heavy metals at phytotoxic concentrations. Only broccolis were contaminated with lead, while amaranths had heavy metals below quality standards. These findings suggest that urban agriculture in large agglomerations of the DRC could endanger consumers' health.
