تقدير بعض العناصر الثقيلة في أسماك البياح الأخضر liza subviridis المجمعة من السواحل البحرية العراقية

Abstract EN

The concentrations of the heavy metals (Cd, Co, Cu, Fe, Mn, Ni), were studied in four organs (liver, Gills, ovaries and muscles) in the body of Liza subviridis, which belong to the family Mugilidae for a period of seven months of the year.

The concentrations of heavy metals were measured by Flame Atomic Absorption Spectrophotometer, and the fish average weight and length were (136.3) g, (231) mm respectively.

The results showed that the highest concentrations value of Nickel in Gills was 109.62 μg/g in December.

The element Iron in the liver was 59.87 μg / g in January, and the element manganese in the ovaries was 15.18 μg / g in March, while the minimum values of the element concentrations, manganese, cobalt and cadmium in the ovaries during the remaining months of the study were below the level of sensing device.

The study showed that the order of accumulation in organs was as follows: liver > Gills > muscles > ovaries.

In general the concentrations of elements during December, January, May and June, were less than March, February and April.
