ABSTRACT
Arsenic pollution is naturally present in groundwater and soils of the main agriculture production area of Argentine. Arsenic in soils, can be taken up and bioaccumulated in plant, and may be bio-transferred to agri-food and humans. All samples collected shown values between 18.6 and 33.1 mg kg−1 of total As. Range percentage of organic matter in analyzed samples were from 6.7 to 24.9%. No significant correlation (p > 0.05) between total As level and organic matter was found. The As concentration in the analyzed samples were above the limits considered inArgentine. However, all samples were into the range previously reported by other authors.
