ABSTRACT
Total As and As speciation were measured in 147 red wines collected worldwide by ICP-MS and HPLC-ICP-MS, respectively. The samples included mid-priced to prestigious wines with vintages covering a period of almost 50 years. Total As concentration ranged from below 0.1 to 56 µg/L (average value 4.0 ± 5.9 µg/L). None of the samples presented a concentration exceeding the limit set by the Office of Vine and Wine of 200 µg/L. Inorganic As was the most abundant form, representing from about half to all total As, mainly as As(III). Dimethylarsinic-acid (DMA) was detected in slightly less than half of the samples, accounting for a few to several dozens of percent. Monomethylarsonic-acid (MMA) was only detected in a few samples. In average, the DMA concentration seemed to be higher in the Bordeaux wines than in the other ones, irrespective of the total As concentration.
