The safety of dairy products ends when toxic compounds and
environmental pollutants (especially heavy metals) concentrations
increase. Detection, estimation and comparison of heavy metals
levels in dairy products with standard, are needed to establish their
safety. (Hegart PV 2008) This issue has been a subject of several
studies all over last decades. (WHO 2006) The highest detected
values for toxic metals in the current study were those of Pb
(7.421 ppm), while the lowest concentrations were of Cd (0.004
ppm).
