On the Scarce Occurrence of Arsenic in Vineyard Soils of Castilla La Mancha: Between the Null Tolerance of Vine Plants and Clean Vineyards

Arsenic (As), a widely distributed metalloid in the Earth’s crust, constitutes one of most significant environmental contaminants today. This study was carried out to determine As concentrations soils Castilla La Mancha (CLM; Spain) benchmark collection that represents all soil orders (soil taxonomy) this territory. It also examined vine plant tolerance relation concentration. For purpose, and leaves from vineyards were collected 10 locations CLM community. The bioconcentration factor (BCF) assessed. results present show content is variable, fundamentally related type parent material. surprising point that, although some have been treated with derivatives, vast majority them do not accumulate any amount As. important finding must be used enhance quality final obtained product: wine. In other words, wines are at risk contamination must, therefore, clean wines. Our suggest by because element reveals null capacity As, process derives scarce traditional practices winegrowers.
