Abstract

Although tomato consumption, whether as tomato paste or tomato ketchup, offers several health advantages, the future prognostic indicators hypothesize the disappearance of these gains due to heavy metal poisoning. Therefore, using the Microwave Plasma Atomic Emission Spectroscopy (MP-AES) technique, this study examined and compared the amounts of arsenic (As), nickel (Ni), cadmium (Cd), lead (Pb), and mercury (Hg) in locally produced and imported tomato pastes and ketchup sold in Nigerian markets. The mean concentrations of these targeted elements in tomato pastes and ketchup (in mg.kg-1) respectively are presented as follows: As (domestic & imported: < LOQ), Ni (domestic:0.308, 0.289; imported: 0.271, 0.267), Cd (domestic:0.088, 0.075; imported:0.078, 0.083), Pb (domestic: 0.121, 0.102; imported:0.128, 0.136) and Hg (domestic and imported:

尼日利亚市场上国产和进口番茄酱中有毒元素含量的比较风险评估

尽管食用番茄，无论是作为番茄酱还是番茄酱，都对健康有益，但未来的预测指标假设，由于重金属中毒，这些好处会消失。因此，本研究使用微波等离子体原子发射光谱(MP-AES)技术，检查并比较了尼日利亚市场上销售的当地生产和进口的番茄酱和番茄酱中砷(As)、镍(Ni)、镉(Cd)、铅(Pb)和汞(Hg)的含量。这些目标元素在番茄酱和番茄酱中的平均浓度(单位:mg.kg-1)分别表示为:as(国产和进口:< LOQ)， Ni(国产:0.308,0.289;进口:0.271、0.267)，Cd(国产:0.088、0.075;进口:0.078、0.083)，Pb(国产:0.121、0.102;进口:0.128,0.136)和Hg(国产和进口:
