| Title | This European Standard specifies a method for the determination of Ag, As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, Se, Tl, U and Zn in foodstuffs by ICP-MS after pressure digestion. The following foodstuffs were analysed in an interlaboratory study: Banana (deep-frozen), Cocoa powder, Wheat noodle powder, Currant nectar (deep-frozen), Milk powder, Oyster (dried), Celery (dried), Dogfish liver (dried), Liver (deep-frozen), Kale (dried) with lower and upper ranges for the following elements elements: As (0,02 mg/kg to 36,6 mg/kg), Pb (0,004 mg/kg to 0,58 mg/kg), Cd (0,006 mg/kg to 15,2 mg/kg), Cr (0,06 mg/kg to 5,71 mg/kg), Co (0,03 mg/kg to 7,49 mg/kg), Cu (0,71 mg/kg to 74,0 mg/kg), Mn (0,31 mg/kg to 73,5 mg/kg), Mo (0,05 mg/kg to 1,88 mg/kg), Ni (0,11 mg/kg to 11,0 mg/kg), Se (0,06 mg/kg to 8,70 mg/kg), Ag (0,011 mg/kg to 1,98 mg/kg), Tl (0,008 mg/kg to 0,12 mg/kg), U (0,003 mg/kg to 0,26 mg/kg), Zn (1,8 mg/kg to 1 582 mg/kg). The ranges analysed in the interlaboratory study, indicating for each element the lowest and highest content found in the ten analysed food matrices. The lower limit of the method’s range varies depending on the food matrix and the food’s water content. It is a laboratory-specific value and is defined by the laboratory for each element when calculating the limit of quantification. |
