| Abstract | ||
| The concentrations of the heavy metals (Co, Cu, Fe, Ni, pb), were studied in four organs (liver, Gills, ovaries and muscles) in the body of Otolithes ruber (gill, liver, muscle, ovaries) The concentrations of heavy metals for a period of November 2011 to February 2012, were measured by Flame Atomic Absorption Spectrophotometer, The results showed that the highest concentrations value of iron (1422.7) µg/gm dry weight in gills, while the minimum values of the element concentrations, manganese, nickel in the gills and 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 > ovaries > muscles. In general the concentrations of elements during Season, winter> spring> autumn> summer | ||
