“…Although the soil acidity was high in this study, the Pb availability was much lower compared to soil used by Jin et al (2005) ( Table 1). On the other hand, the fruits showed a Pb content around 50% lower than in leaves, also below the maximum content reported by Schmidt et al (2009) in coffee fruits (2.7 mg kg -1 ). The element Ag is a heavy metal undesirable at high content (Hamilton;Minski, 1973), and in spite of that, it does not possess maximum levels allowed by Brazilian legislation.…”

Yerba mate leaves are the most studied and used parts of the tree, while fruits have been little investigated as to their elemental composition. The objective of this study was to characterize the composition, the hot-water solubility of the elements and the nutritional value of yerba mate (Ilex paraguariensis St. Hill) fruits and leaves. Both fruits and leaves were collected from four yerba mate provenances (cities of Cascavel, Quedas do Iguaçu and Ivaí in Paraná state and Barão de Cotegipe in Rio Grande do Sul state) 17 years of age, grown in the city of Pinhais, Paraná state, Brazil. The total and hot water-soluble contents of 22 and 20 elements, respectively, were determined. The elemental composition of the fruits presented the following decreasing order: C, K, N, Mg, Ca, P, Al, Na, Zn, Mn, Fe, Ba, Cu, Ni, Mo, Pb, Cr, As, Co, Ag, V and Cd. For the leaves the decreasing order was: C, N, K, Ca, Mg, P, Al, Mn, Na, Fe, Zn, Ba, Cu, Ni, Pb, Cr, Mo, As, Co, Ag, V and Cd. It was found than 2 to 8 elements in the fruit presented greater water solubility than in the leaves. In case of consumption via infusion of the fruits or leaves, there would be nutritive value for K, Mg, P, Mn, Cr, Mo, Cu and Zn, while consumption of capsules would have nutritive value only for Mn via the leaves. In general, the fruits have more distinct elemental composition, hot-water solubility and nutritional value than yerba mate leaves.

“…In several studies, as of Rocha et al (2003) and Trannin et al (2005), Ni concentrations (among other metals) in plants resulting from the addition of residues to the soil were determined. In the literature, studies as conducted by Schmidt et al (2009) are rare, monitoring different metal contents in plants grown on soils in relation to the material of origin of a region (basalt and Caiuá sandstone). According to the Agency for Toxic Substance & Disease Registry (ATSDR), the estimated daily tolerable dosage of Ni for adults of 70 kg is 0.001-0.0024 mg kg -1 day -1 (ATSDR, 2010).…”

Rice is the most cultivated cereal in the world and the main component of human food. Due to the particularity that this crop develops in rainfed areas, irrigated and, mainly, flooded, associated with intense agricultural activity. The final product becomes a potential vehicle, directly or indirectly, of innumerable diseases caused by pesticides used during the phase vegetative; absorption of various cations that, in excess, cause disturbances in man and, percolation in the soil carrying elements or chemical compounds that will contaminate rivers, springs and groundwater. In addition to receiving significant amounts of post-harvest pesticides in search of better storage and conservation. Given the above, the objective of this work is to search the literature for reports of contamination of rice in human food, indicating the need for greater control of the product in the final stage of the production chain, that is, in the stages of culture, harvesting, storage and marketing. Therefore, a way to reduce the possibility of causing diseases to humans due to the load of pesticides applied during their production.
