The aim of this study was to determine the concentrations of heavy metals (cadmium, lead) in providing plain of Ardabil in 2015. This study was cross-sectional, drinking water samples from 100 wells were prepared according to standard procedures. The dimensions of 350 × 350 meter grid station via a station in the network were determined by atomic absorption spectrometry AAS analysis of samples. The data obtained were analyzed using SPSS software. The average concentrations of lead, cadmium in groundwater wells in the area were also studied. The mean concentrations measured in the majority of groundwater wells in the plain of Ardabil lower than the allowed amount were designated according to a national standard.展开更多
