Because of their high toxicity, arsenic, lead and cadmium need to be quantified in food and beverages. For the first time, in this study the content of arsenic, lead and cadmium was investigated in 152 wine samples from the Canary Islands, Spain, belonging to eight Denominations of Origin (DO) and four islands by inductively coupled plasma mass spectrometry (ICP-MS). The ranges of concentration found were 0.58-8.45 g l−1 for arsenic, 0.20-1.73 g l−1 for cadmium and 3.89-159.5 g l−1 for lead, and the mean content was 3.13, 0.63 and 28.74 g l−1, respectively. None of the wines contained levels above the limits set by the International Office of Vine and Wine (OIV), and thus did not pose a health hazard. Significant differences in mean content of those elements between harvest, type of wine, islands and DO were observed.
