摘要：The concentrations of heavy metals (Cd, Cr, Fe, Ni and Pb) in water samples for the Euphrates River in Amiriyah Fallujah, Iraq were evaluated to assess the pollution level. Ten sites were selected along the study area and sampled during December 2013 to March 2014. The decreasing trend of metals were observed in water as Pb > Fe > Cr > Cd > Ni. The concentration of the studied metals was higher than the recommended guidelines for drinking and aquatic life, indicated that the water is not safe for drinking and aquatic life uses. There were significant differences in the concentrations of heavy metal during the sampling period. Heavy pollution index (HPI) results showed that the water was seriously polluted with Cd, Cr and Pb. According to metal index (MI) results, the water is seriously threatened with metal pollution and unsafe for drinking, irrigation and aquatic life uses. Principal components analysis (PCA) suggests that the Cd, Cr and Pb are derived from anthropogenic sources.
