Increase of distribution of environmental contaminants such as heavy metals have been caused
the knowledge of the safety and hygiene of food is very important, especially eggs, because of
its role in the daily diet. There are very few studies about the investigation of the heavy metal
contents in egg-white. In this study, six heavy metals include Aluminium (Al), Arsenic (As), Lead
(Pb), Cadmium (Cd), Mercury (Hg), Antimony (Sb) in egg-white from 32 industrial poultry farms
were investigated, by ICP-OES. All the samples were collected in all area of Markazi Province,
Iran in autumn 2013. The mean concentrations of heavy metals in egg-white as follows: 0.119
for Al, 0.785 for As, 0.750 for Pb, 0.249 for Cd, 0.270 for Hg and 0.186 mg/kg for Sb. Also, the
concentration of the some heavy metals were higher than maximum allowable concentration
that probably it is associated to use pesticides and activities of industrial factories around the
poultry farms.
