Occurrence data of nickel in feed and animal exposure assessment.

ABSTRACT: Nickel (Ni) is a silvery-white, hard, ductile metal existing in oxidation states; in biological systems, Ni²⁺ is the prevalent form. All analytical results used to estimate animal dietary exposure were reported as Ni', without providing information on specific chemical species. Considering the data provided by Member states, among FoodEx level 1 feed categories, the highest mean Ni levels were measured in 'Minerals and products derived thereof' (n = 72). High mean Ni concentrations were also observed in 'Compound feed' (n = 516), in particular in complementary feeds for fattening cattles, unspecified complementary feed and complementary feeds for fattening pigs. Within grains used as feed (n = 597), the highest mean Ni concentrations were measured in oats. In addition, Ni concen
