Being the dietary staple in most Asian countries, the concentrations of toxic and essential element content in rice is an important aspect in terms of both toxicological and nutritional standpoints. This study aimed to analyse trace elements (As, Cd, Pb, Hg, Cr, Ni, Zn, Cu, Mn, Fe, and Mo) in improved, traditional, and imported rice varieties consumed in Colombo district, Sri Lanka during 2018 and 2019. Further, the potential health risks were assessed in terms of maximum levels and provisional tolerable daily intake. Among the toxic elements analysed, As, Cd, Cr, and Pb were detected in certain rice varieties. Arsenic was detected in all three rice categories and the number of As detected samples were higher compared to other toxic elements in 2018 and 2019. In 2018, 4.2% of traditional rice exceeded As maximum level (0.2 mg/kg) whereas 2.1% of improved and 4.2% of traditional rice exceeded Pb maximum level (0.2 mg/kg). However, none of the toxic elements in rice exceeded the respective maximum levels in 2019. Only mean estimated daily intake of Pb through Kaluheenati exceeded the provisional tolerable daily intake value (0.0015 mg/kg bw/d) in 2018. Rice varieties that reported the highest toxic elements were Basmathi (imported), Samba (improved), and Kaluheenati, Madathawalu, Pachchaperuman, and Suwadel (traditional). With regard to essential elements, concentrations of Fe, Zn, Cu, Mn, and Mo in rice were positively correlated (p < 0.05) to each other, and the highest essential element concentration were found in traditional rice with red pericarp (i.e., Kaluheenati, Madathawalu, and Pachchaperuman).

斯里兰卡科伦坡食用大米中有毒和必需元素的评估

作为大多数亚洲国家的主食,大米中的有毒元素和必需元素含量的浓度在毒理学和营养学方面都是一个重要方面。本研究旨在分析 2018 年斯里兰卡科伦坡地区消费的改良稻米、传统稻米和进口稻米品种中的微量元素(As、Cd、Pb、Hg、Cr、Ni、Zn、Cu、Mn、Fe 和 Mo),以及2019. 此外,根据最高水平和临时可耐受每日摄入量评估了潜在的健康风险。在分析的有毒元素中,在某些水稻品种中检测到了 As、Cd、Cr 和 Pb。2018 年和 2019 年,在所有三个大米类别中均检测到了砷,与其他有毒元素相比,检测到的砷样品数量更高。2018 年,4.2% 的传统大米超过了砷的最高水平(0.2 毫克/千克),而 2. 1% 的改良稻米和 4.2% 的传统稻米超过了 Pb 最高水平(0.2 mg/kg)。然而,2019 年大米中的有毒元素均未超过各自的最高水平。2018 年通过 Kaluheenati 的 Pb 估计日均摄入量仅超过了临时的每日可耐受摄入量值(0.0015 mg/kg bw/d)。毒性最高的元素是 Basmathi(进口)、Samba(改进)和 Kaluheenati、Madathawalu、Pachchaperuman 和 Suwadel(传统)。就必需元素而言,水稻中铁、锌、铜、锰和钼的含量呈正相关(p < 0.05),而传统红果皮大米(即Kaluheenati)的必需元素含量最高。 、马达塔瓦卢和帕查佩鲁曼)。然而,2019 年大米中的有毒元素均未超过各自的最高水平。2018 年通过 Kaluheenati 的 Pb 估计日均摄入量仅超过了临时的每日可耐受摄入量值(0.0015 mg/kg bw/d)。毒性最高的元素是 Basmathi(进口)、Samba(改进)和 Kaluheenati、Madathawalu、Pachchaperuman 和 Suwadel(传统)。就必需元素而言,水稻中铁、锌、铜、锰和钼的含量呈正相关(p < 0.05),而传统红果皮大米(即Kaluheenati)的必需元素含量最高。 、马达塔瓦卢和帕查佩鲁曼)。然而,2019 年大米中的有毒元素均未超过各自的最高水平。2018 年通过 Kaluheenati 的 Pb 估计日均摄入量仅超过了临时的每日可耐受摄入量值(0.0015 mg/kg bw/d)。毒性最高的元素是 Basmathi(进口)、Samba(改进)和 Kaluheenati、Madathawalu、Pachchaperuman 和 Suwadel(传统)。就必需元素而言,水稻中铁、锌、铜、锰和钼的含量呈正相关(p < 0.05),而传统红果皮大米(即Kaluheenati)的必需元素含量最高。 、马达塔瓦卢和帕查佩鲁曼)。2018 年,通过 Kaluheenati 估计的每日 Pb 平均摄入量超过了暂定的每日可耐受摄入量值(0.0015 mg/kg bw/d)。报告毒性元素最高的水稻品种是 Basmathi(进口)、Samba(改良)和 Kaluheenati, Madathawalu、Pachchaperuman 和 Suwadel(传统)。就必需元素而言,水稻中铁、锌、铜、锰和钼的含量呈正相关(p < 0.05),而传统红果皮大米(即Kaluheenati)的必需元素含量最高。 、马达塔瓦卢和帕查佩鲁曼)。2018 年,通过 Kaluheenati 估计的每日 Pb 平均摄入量超过了暂定的每日可耐受摄入量值(0.0015 mg/kg bw/d)。报告毒性元素最高的水稻品种是 Basmathi(进口)、Samba(改良)和 Kaluheenati, Madathawalu、Pachchaperuman 和 Suwadel(传统)。就必需元素而言,水稻中铁、锌、铜、锰和钼的含量呈正相关(p < 0.05),而传统红果皮大米(即Kaluheenati)的必需元素含量最高。 、马达塔瓦卢和帕查佩鲁曼)。
