中文摘要：本文对刚果民主共和国金沙萨市和南非约翰内斯堡开放市场上的生鲜食品中有机磷农药残留水平进行了调查研究，并对其潜在的健康风险进行了评估。本文采用QuEChERS方法对市售的120个食品（大豆、白菜、牛肉、鱼肉）样本进行了检测，检测结果显示，约翰内斯堡市售生鲜食品中平均有机磷农药残留浓度显著高于金沙萨市，DDE标记的约翰内斯堡市售牛肉中最高平均残留浓度为253.58μg/kg，alpha-BHC标记的金沙萨市售大豆中最低平均残留浓度范围为38.54μg/kg。健康风险评估显示，检测样本中有机磷农药残留浓度超过了参考剂量。
外文摘要：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 mu g kg(-1)) in beef from Johannesburg, and alpha-BHC recorded the lowest mean concentration (38.54 +/- 7.46 mu g kg(-1)) 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. (C) 2016 Elsevier Ltd. All rights reserved.
