【 摘 要 】

:The state of Rio Grande do Sul (RS) is the largest producer of flood-irrigated rice in Brazil and some fields flooded rice are cultivated for more than 100 years. In rice production are being utilized various inputs, many of which have heavy metals in its composition. This preoccupation considers especially nonessential elements to plants such as Pb, Cr and Cd, which provide risks to human health. This study aimed to quantify the levels of Cd, Cr and Pb in rice grains sold in markets retailers in RS. The elements were extracted from the samples through the USEPA 3050B method and quantified by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). The elements quantified in samples of grains rice sold in markets retailers were within the limits allowed by law.
