Abstract: |
A total of 75 random canned fish samples, 25 each of canned (canned tuna, sardine and mackerel) during 2009, were collected from Zagazig Markets for determination of lead, cadmium, zinc, copper and tin residues using atomic absorption spectrophotometer. The obtained results revealed that the mean values of the lead residues in the examined canned tuna, sardine and mackerel were 0.127 +/- 0.02, 0.013 +/- 0.004 and 0.023 +/- 0.01 (ppm) respectively. The mean concentrations of cadmium residues were 0.022 +/- 0.001, 0.048 +/- 0.003 and 0.027 +/- 0.003 ppm, respectively. While in case of zinc, the residual levels were 1.97 +/- 0.12, 2.369 +/- 0.32 and 1.126 +/- 0.24 ppm, respectively. Copper residual levels in the examined samples were 0.293 +/- 0.08, 0.221 +/- 0.03 and 0.08 +/- 0.02 ppm, respectively. In case of tin, the residual levels were 1.496 +/- 0.30, 1.209 +/- 0.26 and 0.379 +/- 0.11 ppm respectively.
