Abstract

A total of ninty random samples of imported frozen fish represented by Mackerel, Herring and Saurus (30 of each) imported from two different countries namely A and B (15 samples of each fish species for each country) were collected from different fish markets in Menoufiya governorate. The obtained results recorded that the occurrence of cadmium in country (A) were53.33, 40.00 and 33.33% in the Mackerel, Herring and Saurus samples, respectively. In country (B) the cadmium occurrence was 40, 26.67 and 20.00% in the Mackerel, Herring and Saurus samples, respectively. In addition, our results recorded that the percentage of occurrence of lead in country (A) were 66.67, 66.67and 53.33% in the Mackerel, Herring and Saurus samples, respectively; while in country (B) were 60, 46.67 and 40 % in the Mackerel, Herring and Saurus samples, respectively. It could be inferred that regarding the products contamination, the highest cadmium and lead contamination was in mackerel followed by herring then saurus. Regarding the locality, country (A) represented the highest contamination of both cadmium and lead followed by country (B).
