Arsenic in berries and its correlation with natural soil content: experience in Trentino (Italy)

The work illustrates arsenic content in grapes during development and ripening and its distribution in the berry, together with the relationship between As content in grape berries, leaves and soils where this element is naturally present in different amounts. Arsenic increases in the berry during the growing season and is located in the pulp (50%), the skin (40%) and to a lesser extent in the seeds in ripe berries. The correlation between the As content in berries collected in 18 vineyards and in the corresponding leaves and soils, extracted using ammonium acetate, is statistically significant.
