Abstract

One hundred and thirty-five random samples of street vended foods represented by kofta, hawawshi and liver (45 of each)
were collected from Benha (15 of each product), Tukh (15 of each product) and Moshtohor (15 of each product) in
Kalyobia governorate for determination of their content of lead and cadmium. The obtained results recorded that the
occurrence of cadmium in Benha city were 26.67, 40.00 and 46.67% in the kofta, hawawshi and liver samples,
respectively. In Tukh center were 26.67, 46.67 and 60.00% in the kofta, hawawshi and liver samples, respectively.
Whereas in Moshtohor village were 40.00, 53.33 and 73.33% in the kofta, hawawshi and liver samples, respectively. In
addition, our results showed that the percentage of occurrence of lead in Benha city were 20.00, 60.00 and 66.67 % in the
kofta, hawawshi and liver samples, respectively. In Tukh center were 33.33, 40.00 and 53.33 % in the kofta, hawawshi
and liver samples, respectively. Whereas in Moshtohor village were 20.00, 33.33 and 40.00 % in the kofta, hawawshi and
liver samples, respectively. It could be inferred that regarding the products contamination, the highest cadmium
contamination was in liver followed by hawawshi then kofta. Whereas kofta showed the highest lead contamination
followed by hawawishi then liver. Regarding the locality, Moshtohor represented the highest contamination of both
cadmium and lead followed by Tukh then Benha city
