ABSTRACT
This study focused on Human Health Risks Assessment of Organochlorine Pesticide Residues on Staple Grains Sold in Selected Markets in Imo State. The main objectives were to identify and quantify the presence of organochlorine pesticide residues in beans and maize sold in Imo State markets, assess the potential health risks associated with the consumption of these contaminated agricultural products and provide recommendations for reducing human exposure to OCPs through safer agricultural practices and regulatory measures. The study employed a cross-sectional research design to assess the presence and levels of organochlorine pesticide (OCP) residues in beans and maize sold in Imo State markets and to evaluate the associated human health risks. The study involved both fieldwork (sample collection) and laboratory analysis (pesticide residue detection and quantification). The GC-MS results indicated some significant levels of various OCP residues, including DDT, aldrin, dieldrin, endosulfan, and heptachlor, in beans and maize samples. This indicates OCP contamination in agricultural produce sold in Imo State markets. Prolonged exposure to these pesticides, even at low levels, can lead to serious health issues, including cancer, endocrine disruption, and neurological disorders. The presence of OCP residues in commonly consumed food items such as beans and maize pose a significant threat to food safety and public health. The findings underscore the need for urgent action to address this issue through improved regulatory enforcement, monitoring, and public awareness campaigns.
