Determination of Metals in Foods by Atomic Absorption Spectrometry after Dry Ashing : NMKL 1 Collaborative Study

  title={Determination of Metals in Foods by Atomic Absorption Spectrometry after Dry Ashing : NMKL 1 Collaborative Study},
  author={National Food Administration}
A method for determination of lead, cadmium, zinc, copper, and iron in foods by atomic absorption spectrometry (AAS) after dry ashing at 450 °C was collaboratively studied in 16 laboratories. The study was preceded by a practice round of familiarization samples and another round in which solutions were distributed and the metals were determined directly by AAS. The study included 5 different foods (liver paste, apple sauce, minced fish, wheat bran, and milk powder) and 2 simulated diets. A…

ABSTRACT Concentration of five heavy metals including lead (Pb), cadmium (Cd), copper (Cu), iron (Fe), and zinc (Zn) in wheat collected from silages of Golestan Province, Iran, was determined using

Consumption of heavy metal contaminated foods and associated risks in Bangladesh

A comprehensive approach would provide guidelines to formulate adequate control measures and regulatory limits of toxic metals in foods produced and marketed in Bangladesh and ensure the risks associated with food consumption below the allowable carcinogenic and non-carcinogenic risk levels.

Determination of Heavy Metal Ions (As, Pb, Cd) and Zinc Mineral (Zn) in Humans and Cows Milk in Bitlis (Turkey)

Human’s milk and cow’s milk fed-infants, long before the mother is exposed heavy metals are potentially dangerous for both mother and baby. Concentrations of toxic heavy metals (Pb, Cd, As) and major

Extrinsic iron from soil contributes to Hb regeneration of anaemic rats: implications for foods contaminated with soil iron

Soil contamination significantly increased the exchangeable, acid-soluble and reducible fractions obtained after sequential extraction and can contribute to Hb regeneration in Fe-deficient rats, considering that contamination of foods with soil is common in Ethiopia and other developing countries.
