A STUDY OF SOME CHEMICAL PROPERTIES OF CANNED FISH PRODUCTS IN LOCAL MARKETS IN BASRAH CITY,IRAQ

Abstract

Concentrations of seven heavy metals (Cadmium, Lead, Zinc, Nickel, Iron,Copper and Manganese) in five canned fish samples found in the local market Basrahcity, Iraq were determined after digestion according to the Association of OfficialAnalytical Chemists methods. Concentrations of metals were measured using theFlame Atomic Absorption Spectrophotometer. The results showed that the rangeobtained for the elements analyzed in mg/kg (dry weight) were as follows, Cd (0.0027- 0.0078), Pb (0.0048 - 0.0093), Zn (0.0103 - 0.0205), Ni (0.0122 - 0.0128), Fe(0.0149 - 0.0237), Cu (0.0008 - 0.0034) and Mn (0.0014 - 0.0037). The resultsindicated that canned fish samples in this study have concentrations well below thepermissible FAO/WHO levels for these toxic metals.
