A total of 100 random eggs and egg products (40 egg samplescollected form farms cited in non industrial area and 50 egg samplescollected from farms cited in industrial area, along the main road of heavy traffics. Egg products (4 egg white powder, 4 egg yolk powdered and 2whole egg powder) samples were collected from Animal Health ResearchInstitute (Dokki branch). Egg samples were examined physically and allsamples were digested and analyzed by Atomic Absorption Spectrophotometry for determination of cadmium, lead, mercury, copper and zinc. In egg samples collected from farms cited in non industrial area.Egg weight, specific gravity, shell thickness, shell weight percentage andshell weight ranged from 44.99 to 71.80 gram, 1.06 to 1.09,0.28 to 0.42mm, 8.30 to 13.90% and 4.30 to 8.20 gram respectively with an average of56.23 gram, 1.08, 0.35 mm, 10.91 % and 6.11 gram respectively. While, itranged from 42.44 to 75.19 gram, 1.04 to 1.09,0.26 to 0.38 mm, 7.40 to13.70% and 4.12 to 8.18 gram respectively with a mean level of 58.25gram, 1.08, 0.32 mm, ] 0.260/0 and 6 gram respectively in examinedsamples collected from industrial area. There was a significant differencebetween industrial and non industrial area in the egg weight, shell thicknessand shell weight percentage of egg samples. Cadmium, lead, mercury,copper and zinc concentrations ranged from 0.30 to 1.90 ppm, 1.70 to 10ppm, 0.62 to 1.38 ppb, 0.67 to 8 ppm and 3.10 to 14.10 ppm respectivelywith a mean of 0.94 ppm, 4.37 ppm, ] .06 ppb, ] .56 ppm and 8 ppmrespectively in examined egg samples collected from non industrial areaand it range from less than 0.01 ppm to 10 ppm, 1.70 to 43 ppm, 0.61 to5.90 ppb, less than 0.1 to 30 ppm and less than 0.1 to 87 ppm respectively
