Detection and Determination of Heavy Mineral Elements in Some Types of Canned Meat Sold in the Domestic Market


Abstract in English

This study was conducted to determine some heavy minerals in different types of canned meat sold in the domestic market. Most of those cans were imported and processed in different countries and they have different brands. The chosen samples after ashing were prepared by using concentrated extra pure Nitric and Hydrochloric acids .The ratios of the minerals )pb , Cd , Ni , Zn , Cu , Mn , Fe ( were determined by Atomic Absorption Spectrophotometry , and the content was expressed as (p.p.m) wet weight. It was observed that the levels of Lead, Iron, and Cadimum, in all different samples were higher than the permitted limlts according to the Syrian Standards . The Cu level in both , tuna and sardine was within the permitted limits, but it was higher in the chicken Lunchoen. The level of Zinc was within the permitted limits according to the Syrian standards. The highest ratio of Lead was observed in the sardine imported from Morocco which was 8.765 p.p.m and in the Lunchoen processed in Syria which was 5.18 p.p.m ,and both ratios are much higher than the permitted limits according to the Syrian Standards.
