Determination of lead and cadmium in food stuff at Khartoum state by atomic absorption spectroscopy
Eman S Bushara, Elsheikh E Elbasheer
The samples of natural food with different kinds (vegetables, fruits, legumes, meat, milk) were collected from three locations in Khartoum state. Omdurman, Bahri and Khartoum. The samples were treated for reading by atomic absorption spectroscopy (AAS) with stander Method for determination of heavy metals the results of cadmium concentration are within levels of World Health organization. Except for vegetables they are higher than maximum limit levels of World Health organization (In addition, cadmium levels in vegetables at bahri area were higher than Omdurman and Khartoum areas) but it not reached the toxicity limit. This due to use Fertilizers. And the mean concentrations of lead within World health Organization. Maximum permitted concentration in parts per million according WHO: Cadmium (Cd:) legumes s and vegetables (0.1ppm), Fish and meat (2ppm) Meat of animal (0.2ppm). Lead (Pb): All food in solid form all food in liquid form (6ppm), all food in liquid form (1ppm).
