Contents and Spatial Distribution of Arsenic in Vineyard Soils in Mediterranean Environment
This study presents the contents and spatial distribution of arsenic (As) in vineyard soils from the Valdepeñas Protected Designation Origin (PDO) in central Spain. As content varies within the 108.40–0.03 mg·kg−1 range in surface horizons, and within 151.00–0.03 mg·kg−1 in subsurface horizons. The...

| Resumo: | This study presents the contents and spatial distribution of arsenic (As) in vineyard soils from the Valdepeñas Protected Designation Origin (PDO) in central Spain. As content varies within the 108.40–0.03 mg·kg−1 range in surface horizons, and within 151.00–0.03 mg·kg−1 in subsurface horizons. The mean value of both horizons is similar: 4.25 and 4.88 mg·kg−1, respectively. Based on optimal spatial interpolation, the spatial distribution of As in soils was mapped by the IDV method. A simple data and map analysis suggests that pedogeogenic sources are the main sources for As (the As distribution tends to match the lithology and soil types), which indicates minor anthropogenic sources, mainly by agricultural sector activities. Only a high As concentration appears in the NE area, where sporadic moderate contamination is estimated based on Dutch criteria. The data obtained from the study area provide a broader view of the concentration, distribution, enrichment, sources, and the potential environmental contamination by As in the vineyard soils of this large winegrowing zone. The assessment of the results indicates that As does not afect agriculture (vineyards) in the study area because its concentrations are low in the soil types used by agriculture. These data can be employed as a guide to learn the range of values in vineyard soils in the European Mediterranean Region that are relatively unpolluted from industrial sources to make comparisons to more polluted areas |
