title: Metal concentrations in the groundwater in Birjand flood plain, Iran.
abstract: The objective of the present study was to investigate the concentration of metals (cadmium, lead, chromium, zinc, copper, and iron) were measured in groundwater at 30 sites from the Birjand flood plain of eastern Iran during the November 2010; identify any relationships between metals and pH, total hardness. Metal concentrations in the groundwater samples were decreased in sequence of Zn > Fe > Cu > Cr > Pb > Cd, respectively. The results showed that the overall mean concentrations of Cd, Pb, and Cr were at 0.000, 0.023, and 0.049 mg l(-1), respectively. The mean concentration of Cu, Zn, and Fe were 0.109, 0.192, and 0.174 mg l(-1), respectively. Results also indicated that there were correlations among Cd, Cu, and Zn metals.
