dc.description.abstractThis study was designed to estimate the dietary intake of lead, arsenic and cadmium by schoolchildren population (aged 6 to 12) of northwest Argentina. Calculations were based on a 24-h dietary recall survey. A total of 1027 completed surveys were analyzed in both provinces. From the observed consumption, 22 composite samples were prepared from individual food items and water samples. For lead, 30% of the food samples were found below the LOD and 40% below the LOQ. For cadmium, 76% of the samples were below the LOD and 16% below the LOQ. For arsenic, only one sample showed values higher than LOD and LOQ. The exposure was similar to that observed in other studies, with mean results of 0.6 μg/kg bw/day for lead, 0.002 μg/kg bw/ day for cadmium and 1.7 μg/kg bw/day for arsenic in the locality with this pollutant present in water. Although exposure levels do not exceed the limits established by the Joint FAO/WHO Expert Committee on Food Additives, the presence of these contaminants in food should be monitored, taking into account that children are more susceptible to their neurotoxic effects.pt_PT
