This study aimed to determine the concentrations of selenium, zinc and copper in foods generally composing the diet of Northern Italy population in order to implement a database of the quantitative content for each of the three trace elements, according to food category intake.
Food samples were collected from (small to large) distribution markets in triplicates and trace elements determination was performed with ICP-MS after sample mineralization. We found the highest levels of selenium in meat (202 μg/kg), fish and seafood (489), dry fruits (314) and legumes (220). The level of cadmium was higher in sweets (60.33 μg/Kg), dry fruit (μg/Kg) and fish and seafood (29.37 μg/Kg). The level of zinc was higher in cereal products (11.7 mg/kg), meat (28.4), dairy products (18.8), legumes (21.2) and dry fruits (37.8). Finally, the highest concentration of copper was found in dry fruits (14.9 mg/kg), legumes (6.2), sweets (4.1) and meat (3.7). Our findings will allow to estimate dietary trace elements exposure which could be useful for both toxicological and epidemiological studies.
