Evaluation of seasonal dietary exposure to arsenic, cadmium and lead in schoolchildren through the analysis of meals served by public schools of Ribeirão Preto, Brazil

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).
