Human health risk assessment based on consumption of Amaranthus viridis, in sub-Saharan African country.

The contamination of water resource and food chain by persistent organic pollutants POPs (including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs)), and polycyclic aromatic hydrocarbons (PAHs)) constitutes a major environmental and human health concern worldwide. This study investigates the levels of POPs in irrigation water, soil and in Amaranthus viridis (Amaranth) from different gardening sites in Kinshasa to evaluate the potential environmental and human health risks. Amaranthus spp. are among of the most domestic vegetables consumed in south of Asian and sub-Saharan African countries. The results show high POPs (mainly OCPs and PAHs) levels in amaranth from all studied sites. Higher estimated daily intake values indicate that consuming leafy vegetables might associate with increased human health risks. However, calculated incremental lifetime cancer risk values indicates no potential carcinogenic risk for the local population.
