Abstract
Uptake of different
heavy metal residues including cadmium (Cd), chromium (Cr), nickel (Ni), led (Pb),
arsenic (As), and mercury (Hg) were determined in goat and cattle milk collected from two areas, each consisted of three
sites. Area 1 was selected in the north-east and Area 2 in the north-west of Faisalabad city along the main sewerage
drains. Levels of Cd, Cr, Ni, Pb, As and Hg in the milk
of goat and cattle were higher than the most reported values in the literature.
The levels of heavy metal residues in the milk of cattle from Area 1 had higher
levels than those present in cattle milk from Area 2. However, in case of goat
milk the residual values from Area 1 and Area 2 were non-significantly
different. It was concluded that the levels of Cd, Cr, Ni, Pb, As and Hg in the
milk of goat and cattle were higher than reported values in the literature.
