This study aimed to analyse the concentrations of Al, Ba, Bi, Cu, Cr, Ge, Mn, Mo, Ni, Sb, Se, Sr and Zn in food samples collected in 2008 in Catalonia (Spain). The dietary intake of these 13 trace elements was subsequently estimated by different age-gender groups of the population: children, adolescents, adults and seniors. In general terms, fish and shellfish, cereals, and pulses were the food groups showing the highest levels for most elements. Higher dietary intakes were associated with male groups (adolescents, adults and seniors). However, none exceeded the tolerable levels. When exposure was estimated based on body weight, children were the group with the highest dietary intake. Notwithstanding, only the weekly intake of Al by children exceeded the recommendations of the European Food Safety Authority (EFSA). It is a consequence of the higher intake of cereals in relation to their respective body weights. In addition to the periodical food surveillance of toxic metals (As, Cd, Hg and Pb), it is also important to determine the levels of other trace elements in order to ensure that the dietary exposure by the Catalan population is under control.
