This study evaluates essential and toxic element contents in dragon (Hylocereus undatus (Haworth) Britton and Rose) and pomegranate (Punica granatum L.) and possible health risks through the consumption of these fruits. Total concentrations of 15 chemical elements (Al, Br, Ca, Cd, Cl, Cr, Cu, Fe, Hg, K, Mn, Na, Ni, Pb, and Zn) were determined by instrumental neutron activation analysis (INAA) and atomic absorption spectrometry (AAS) techniques. This study indicates that these fruits are a vital source of essential elements for human health. It is observed that Pb concentrations were higher in both fruits whereas Cd concentrations were slightly higher than WHO/FAO tolerable levels only in pomegranate. The estimated daily intake (EDI) of the chemical elements was within the maximum tolerable daily intake (MTDI) values. Furthermore, target hazard quotient (THQ) values were also within the safe level (THQ < 1). However, the calculated target carcinogenic risk (TCR) values of Cd for pomegranate and Cr for dragon fruit were higher than the maximum limit (1.0 × 10) for children. Finally, this study will create public awareness about micronutrient contents as well as metal contaminations of the studied fruits.
本研究通过评估火龙果（Hylocereus undatus (Haworth) Britton and Rose）和石榴（Punica granatum L.）中的必需元素和有毒元素含量，以及食用这些水果可能带来的健康风险。采用仪器中子活化分析（INAA）和原子吸收光谱法（AAS）技术，对这 15 种化学元素（Al、Br、Ca、Cd、Cl、Cr、Cu、Fe、Hg、K、Mn、Na、Ni、Pb 和 Zn）的总浓度进行了测定。本研究表明，这些水果是人体健康必需元素的重要来源。结果表明，两种水果中 Pb 的浓度均较高，而 Cd 的浓度仅在石榴中略高于世界卫生组织/粮农组织可耐受水平。化学元素的估计每日摄入量（EDI）均在最大耐受日摄入量（MTDI）值以内。此外，目标危害系数（THQ）值也在安全水平内（THQ<1）。然而，对于石榴中的 Cd 和火龙果中的 Cr，计算得出的目标致癌风险（TCR）值均高于儿童的最高限值（1.0×10）。最后，本研究将提高公众对所研究水果中微量元素含量和金属污染的认识。
