Determination of mercury, nickel and copper in some types of canned fish and meat

الملخص EN

In this study, three heavy metals (mercury, nickel and copper) in twenty eight canned fish and meat samples were determined by atomic absorption spectrophotometer.

The metal contents, expressed in ppm (mg / L), varied from 0.01 to 3 ppm in canned fish and from 0.001 to 2 ppm in canned meat for mercury, from 0.0001 to 0.0003 ppm in canned fish and from 0.0001 to 0.0007 ppm in canned meat for a nickel, and from 0.001 to 0.01 ppm in canned fish and from 0.001 to 0.1 ppm in canned meat for copper.

The results of this study showed the concentration of mercury in fish and meat samples exceed normal levels, and statistical analysis of results by ANOVA showed significant differences between fish and meat in some samples for mercury.
