Abstract
Government of Pakistan confined importers of wheat, both public and private to ensure acceptable quality of wheat meeting FAO and
WHO standard. Monitoring of wheat quality i.e. physical, chemical and biological was carried out at Grain Quality Testing
Laboratory, Karachi, Pakistan. The contents of heavy and essential trace metals were also assessed. Samples of wheat from various
countries were imported through TCP (Trading Corporation of Pakistan). These samples were packed properly and forwarded to
laboratory for analysis of some heavy (Cd, Pb, As, Hg) and essential trace metals (Zn, Cu, Fe, Mn, and Mg) contents. The metals
concentrations found in the samples were in order of Mg >Fe > Cu > Zn > Mn > Pb > Cd > Hg > As. The metals contents found were
under the permissible limits.
