摘要

在过去十年中，农药在农业中的使用有助于保护作物，但在食品中留下了残留物，构成了健康风险。本研究分析了加纳两个社区莴苣和青椒中的有机氯（δ -六氯环己烷和β -六氯环己烷）和有机磷（毒死蜱和乐果）残留。对31名农民进行了调查，并用气相色谱法对样品进行了检测。毒死蜱含量为0.1403-0.2291毫克/公斤，超过欧盟和美国的最高残留限量，而青椒则没有残留。调查结果强调需要持续进行农药监测和公众教育，以确保食品安全和健康。

Organochlorine and organophosphate residues in lettuce and green pepper in Ghana's mega city

Over the last decade, pesticide use in agriculture has helped protect crops but left residues in food, posing health risks. This study analyzed organochlorine (Delta-HCH and Beta-HCH) and organophosphate (chlorpyrifos and dimethoate) residues in lettuce and green pepper from two communities in Ghana. Thirty-one farmers were surveyed, and samples were tested using Gas Chromatography. Chlorpyrifos, found in lettuce from Legon farm at 0.1403–0.2291 mg/kg, exceeded EU and USA Maximum Residue Limits, while green pepper contained no residues. Findings emphasize the need for ongoing pesticide monitoring and public education to ensure food safety and health.
