Dietary exposure to arsenic (AS), cadmium (Cd), and lead (Pb) of Brazilian schoolchildren living in Ribeirão Preto, Brazil, was assessed. Food samples including rice, beans, vegetables, fruits, and meat served daily by public schools were collected as presented in different seasons. Metallic elements were determined by inductively coupled plasma-mass spectrometry (ICP-MS).The main sources of As, Cd, and Pb were found to be rice, vegetables, and pork, respectively. Further, in some food types there were seasonal differences in the concentrations of metallic elements. The mean daily intakes of As, Cd, and Pb based upon the association between food consumption data and the observed concentrations of metals in their diet were 6.9 μg, 0.9 μg, and 0.6 μg for As, Cd, and Pb, respectively. These findings are below the toxicological reference values provided by the European Food Safety Authority (EFSA) and the World Health Organization (WHO).
评估了巴西里贝朗普雷图的巴西学童的饮食砷（AS）、镉（Cd）和铅（Pb）暴露情况。收集了公立学校每天供应的大米、豆类、蔬菜、水果和肉类等食物样本，并按不同季节呈现。采用电感耦合等离子体质谱法（ICP-MS）测定金属元素。结果表明，砷、镉和铅的主要来源分别为大米、蔬菜和猪肉。此外，在某些食物类型中，金属元素的浓度存在季节性差异。根据食物消费数据与饮食中金属浓度的相关性，基于食物消费数据和饮食中金属浓度的相关性，每日砷、镉和铅的平均摄入量分别为 6.9μg、0.9μg 和 0.6μg。这些发现低于欧洲食品安全局（EFSA）和世界卫生组织（WHO）提供的毒理学参考值。
