人们越来越关注在垃圾场附近/之上/内部生长的可食用植物对健康的影响。这项研究调查了两种食用蔬菜：苋菜和三角菜（Jacq），它们生长在尼日利亚一个主要的非正式电子废物垃圾场附近。测量了蔬菜中多环芳烃（PAH）、多氯联苯（PCB）、多溴二苯醚（PBDE）和重金属的含量。使用危害指数（HI）、终生癌症风险（LCR）、估计每日摄入量（EDI）和危害商（HQ）评估食用蔬菜的健康风险。采用鼠伤寒沙门氏菌（TA100、TA98）Ames沙门氏菌波动试验和大肠杆菌（PQ37）SOS显色试验，评价蔬菜的致突变性和遗传毒性。这两种蔬菜的重金属、多溴联苯醚、多氯联苯和有害多环芳烃含量较高。与A.hybridus 相比，T.trianglee 的污染程度更高。蔬菜中有机成分和重金属的含量呈良好相关性。 HQ、HI 和 LCR 的水平高于建议的指导值，表明存在致癌和非致癌后果的显着风险，特别是对于儿童。在艾姆斯测试中，这两种蔬菜即使在 50% 浓度下也具有致突变性。 SOS-chromo 测试结果证实了这一点，表明这两种蔬菜确实具有遗传毒性。这项研究证明了在垃圾场附近种植粮食作物的有害影响；因此，应采取充分措施，阻止农民和个人利用垃圾场中的泥土作为肥料，或在过去或现在曾用作垃圾场的土壤中进行种植。版权所有 © 2024 Elsevier B.V. 保留所有权利。

There has been a growing concern on the health effect of edible plants growing near/on/within the vicinity of dumpsites. This study investigated two edible vegetables: Amarathus hybridus and Talinum triangulare (Jacq) grown in the vicinity of a major informal dumpsite of electronic waste in Nigeria. The levels of polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and heavy metal concentrations in the vegetables were measured. The health risks of consuming the vegetables were assessed using the hazard index (HI), lifetime cancer risk (LCR), estimated daily intake (EDI), and hazard quotient (HQ). Using the Ames Salmonella fluctuation test on Salmonella typhimurium (TA100 and TA98) and the SOS chromo test on Escherichia coli (PQ37), the mutagenicity and genotoxicity of the vegetables were evaluated. The two vegetables have elevated levels of heavy metals, PBDEs, PCBs, and hazardous PAHs. Compared to A. hybridus, T. triangulare was more contaminated. The amounts of organic constituents and heavy metals in the vegetables correlated favorably. The levels of the HQ, HI, and LCR were above the suggested guideline values, indicating a significant risk of both carcinogenic and non-carcinogenic consequences, particularly in children. The two vegetables were mutagenic even at 50 % concentration in the Ames test. This was corroborated with SOS-chromo test results showing that the two vegetables were indeed genotoxic. This study demonstrated the harmful effects of growing food crops close to dumpsites; therefore, sufficient measures should be implemented to stop farmers and individuals from utilizing dirt from dumps as fertilizer or from planting in soil that has been used as a dump in the past or present.Copyright © 2024 Elsevier B.V.
