Popis: | 36 samples representative of the 1981 Italian durum wheat crop were separated by an industrial Italian milling process and the products obtained analyzed by AAS for their Pb, Cd, Cr, Cu, Zn content. The results obtained were: Pb ranging from 0.04 to 0.80 ppm, Cd from 0.02 to 1.39 ppm, Cr from 0.05 to 1.60 ppm, Cu from 1.8 to 39.7 ppm and Zn from 8.8 to 117.6 ppm. Although Cr content was relatively homogeneous, Pb, Cd, Cu and Zn distribution in the various mill products proved to be rather inhomogeneous. Maximum contamination for Pb, Cd and Cr, was appreciably lower than in previous studies. |
