中文摘要：库马西、塞康第-塔科拉迪和阿克拉是加纳的主要农产品消费市场，为了保证粮食安全、满足粮食需求并减轻病虫害威胁，在种植蔬菜和水果的过程中会使用农药，本研究对三个主要农贸市场上的番茄农药残留进行了检测，检测结果显示：Ayigya市场上番茄样本含有高浓度的机磷农药残留（45%），Bantama市场上的样本含有高浓度的有机氯及拟除虫菊酯类农药残留，但各种农药残留风险指数均低于1，对人体健康不构成威胁，而七氯（HI = 0.85）和狄氏剂（HI = 0.74）对儿童健康威胁最大，因此，要对番茄中七氯和狄氏剂农药残留进行严格监控。
外文摘要：Kumasi, Sekondi-Takoradi, and Accra are the major recipients of agricultural commodities or productions in Ghana, primarily due to their population and ready markets. To ensure food security, meet food demands, and mitigate the threats posed by pests and diseases, pesticides are used when cultivating vegetables and fruits in Ghana. The present study has been conducted to assess the concentration of various pesticide residues in tomatoes, obtained from three market centers (namely Bantama, Central, and Ayigya Markets) in Kumasi, dealing with potential health risks for the consumers. Analyzed samples have revealed high percentage of organophosphorous pesticide residues (45%) in Ayigya market with Bantama market recording high percentage of organochlorines and pyrethroid. Laboratory analysis of tomato samples for various pesticides residues has indicated that all the pesticide residues pose no threat to human's health with all estimated hazard indices being below 1; however, heptachlor (HI=0.85) and dieldrin (HI=0.74) have shown the highest risk levels in children. The study reveals that there is some need for strict monitoring of heptachlor and dieldrin in tomato, especially in case of children.
