In the frame of a study aimed at investigating the transfer of metal contaminants through the food chain and the effects of food processing, five elements, namely Cd, Pb, Fe, Ni and Cr, were accurately determined in (i) durum wheat grain and derived products, (ii) wheat-based reference materials, (iii) drinking water, used both as an ingredient and for technological purposes in the investigated industrial...
The analytical issues connected with chromium determination in foodstuffs by quadrupole inductively coupled plasma-mass spectrometry (Q-ICP-MS) were addressed, including signal stability, spectral interferences and the use of mathematical correction equations. The analytical performance was compared to that of electrothermal atomisation-atomic absorption spectrometry (ETA-AAS), selected as reference...
