Abstract
This work evaluated the multi-element concentration in grape must and soil samples employing inductively coupled plasma optical emission spectrometry (ICP OES), after microwave-assisted digestion. The study aimed to establish a profile of seven grape varieties produced in Petrolina, region Submedium São Francisco, Brazil. Principal component analysis (PCA) clearly showed a good separation of samples in terms of mineral constituents. Although some soil samples showed concentrations of Co, Cu and Ni higher than the prevention values (VP), no sample exceeded the values stipulated for an intervention in agricultural soils based on Resolution No. 420/2009 of the National Council for the Environment (CONAMA). So, the results obtained contribute to food mineral composition table, as it brings unprecedented information about the concentration of the elements in seven grape varieties, providing indicators of geographic location, and contributing to the preliminary construction of a geochemical base of the regional soil.
