| Abstract |
In the present study, nine hundred and fifty one samples of different commodities from the most common fruits and vegetables in Egypt (cabbage, coriander, dill, grape leaf, lettuce, molokai, parsley, spinach, water cress, cucumber, egg plant, green peas, onion, pepper, squash, taro, tomato, carrot, potato, apple, banana, orange and strawberry) were collected from Egyptian local markets in six Governorates (Cairo, Beni suief, Giza, Minifiya, Ismailia and Qaulubiya) during the period from beginning 1996 to the end of 1997. All samples were subjected to heavy metals analysis capable for detection for lead, cadmium, and copper elements.
The most frequently detected element in all analyzed samples collected from. all six Governorates was Cu element. The percentage of contamination with Cu was 100% in plant samples collected from all six Governorates, the violation percentage was 0.21 %.
The most violated element in all vegetables and fruits samples analyzed collected from all six Governorates was Pb, where the violation percentage was 20.5%, and the contamination percentage was 72.9% (out of 951 total samples analyzed). However, 74.2% of all samples analyzed were contaminated with Cd, and only 1.26% of contaminated samples was violated. Data showed that total vegetables showed higher violation percentage 21.4% than fruits (17.4%) and that might be attributed to higher violation percentage of leafy vegetables, which reached 25.3%. Also, it was found that Qalyubiya recorded the highest violation percentage in total vegetables (28%), while Minufiya recorded the highest violation in fruits (33.3%).
Key words: Heavy metals, Lead, Cadmium and Copper, Vegetables, Fruits, Monitoring.
