Estimation of some heavy metals in the Dalmaj Marsh, AL-Diwaniya City, Iraq.

Abstract

The current study has investigated Cd, Pb and Ni heavy metals of the Dalmaj Marsh, located in AL-Diwaniyah City, in Iraq. The results show that there has been a variation in heavy metals in the three studied sites. the mean values of concentrations in water were 1.96, 4.27, and 2.11µg/l for Cd, Pb and Ni respectively. Pollutants such as pesticides, sewage discharge, irrigation and electronic waste are the main pollutants in the pollution of freshwater bodies including marshes. These findings provide crucial background data for further research in order to obtain better management and protection for Iraqi freshwaters
