This study investigates the level of organochlorine pesticides in the raw food from open markets in Kinshasa, Democratic Republic of Congo (DRC), and Johannesburg, South Africa. It assesses the potential health risks associated with the organochlorine pesticide residues. The Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method has been developed for sample preparation. A total of 120 food samples (beans, cabbage, beef, and fish) were obtained from the open markets. The mean concentrations of organochlorine pesticides in raw foods collected from the Johannesburg market were significantly higher (p < 0.05) than those from the Kinshasa market. DDE recorded the highest mean concentration (253.58 ± 4.78 μg kg) in beef from Johannesburg, and α-BHC recorded the lowest mean concentration (38.54 ± 7.46 μg kg) in beans from Kinshasa. The investigation of health risk estimates revealed that the number of organochlorine pesticides exceeded the reference dose in the collected food samples.
本研究调查了刚果民主共和国（DRC）金沙萨和南非约翰内斯堡露天市场的生食中有机氯农药的含量水平。它评估了与有机氯农药残留相关的潜在健康风险。已开发出快速、简便、廉价、有效、耐用且安全（QuEChERS）的样品制备方法。从露天市场共采集了120份食品样本（豆类、卷心菜、牛肉和鱼类）。从约翰内斯堡市场采集的生食中有机氯农药的平均浓度显著高于（p < 0.05）金沙萨市场的。在约翰内斯堡牛肉中，滴滴伊（DDE）的平均浓度最高（253.58 ± 4.78 μg/kg），而在金沙萨豆类中，α-六六六（α-BHC）的平均浓度最低（38.54 ± 7.46 μg/kg）。健康风险评估调查显示，所采集的食品样本中有机氯农药的数量超过了参考剂量。
