Updated method for determination of metals in foodstuffs

NMKL procedure No. 139, "Metals. Determination by atomic absorption spectrophotometry in foodstuffs" has been updated. The change from the previous version is the inclusion of the matrixes included in the collaborative study and the results thereof. In the previous version, chromium and nickel were included. However, the results of the collaborative study for these elements were not satisfactory and hence it is concluded that the method does not seem to be the best for these metals.
