Abstract
A total of 47 random samples (colostrum of buffalo's and cows, ice cream, butter, balady yoghurt, baby foods, yoghurt and kishk) were collected from different outlets in Assiut Governorate. The collected samples were analyzed for the detection of lead, cadmium, iron, selenium, manganese and mercury by using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). The analyzed data showed that the mean values in the examined colostrum buffalo's and cows were (0.0155 and 0.0157) lead, (0.0008 and 0.0.0006) cadmium, (1.5528 and 0.5838) iron, (0.0055 and 0.00023) selenium, (0.0236 and 0.0379) manganese and (0.0094 and 0.0003) ppm mercury, respectively. Results revealed that the mean values in ice cream, baby foods, balady yoghurt, yoghurt, kishk and butter samples for lead, cadmium, iron, selenium, manganese and mercury were (0.0139, 0.0103, 0.0155, 0.0119, 0.0544 and 0.0179); (0.0014, 0.0006, 0.0003, 0.0000, 0.0008 and 0.000004); (0.3912, 2.9768, 7.6998, 0.3189, 4.0753 and 0.6160); (0.0027, 0.0035, 0.0041, 0.0000, 0.0012 and 0.0035); (0.0409, 0.1309, 0.0543, 0.0221, 1.6603 and 0.0173) and (0.0023, 0.0069, 0.0000, 0.0000, 0.0006 and 0.0000)) ppm, respectively. The results showed that there werea significant levels of positive correlation (p<0.05) between the Pb and Cd contents, and highly significant positive correlation (p<0.01) between the levels of Pb and Mn as well as between the values of Se and Hg, respectively.
