Effect of quarterly changes on the concentration of heavy metals in Al-Zubaidi (Pampus argenteus)‎ collected from Iraqi marine coasts

Abstract EN

In the present study concentrations of some heavy metals calculated in three tissues (Liver, gills, and muscles) of Al-Zubaidi fish (Pampus argenteus), which date back to the family Stromateidae, that collected from Iraqi marine coasts, during December 2014 to March 2015.The concentrations of the studied heavy metals (Cobalt, Iron, Nickel, Manganese, Copper, and Cadmium) measured by Flame Atomic Spectrophotometer), and results showed that their highest concentrations were in the liver (16.71, 98.9, 88.13, 10.99, 30.22,and 12.69)μg/g respectively, while the lowest concentrations appear in white muscles (1.16, 5.2, 2.87, 40.68, 3.69, 55.23) μg/g.

In the studied period, concentrations of the heavy metals were higher in liver than that in the muscles and gills.

The order of seasonal concentration of heavy metals in the muscles were Summer> Spring> Autumn> Winter
