Pollution has become a global problem and the results are implied in high levels of contaminations reported for soil, water, air, plants and animals. In the present study, Al-Nahrawan is one of the most known industrial regions in Iraq. Samples of soil, water and air were taken for study. These samples were contaminated by different heavy metals like Pb, Cr, Cu, Fe and Zn that were characterized with low pH when compared with normal non industrial regions. The present results indicate that Al-Nahrawan region is affected widely by heavy metals contamination in soil, water and air as a result of industrial activities.
