Abstract :

In this study, three hot springs were examined including Karimi (1), Iranzamin (2), and Hosseini (3) located in Lavij region of Chamestan in Mazandaran Province located at 51˚, 58΄, 17˝-52˚, 04΄, 27˝ longitude from the east and 36˚, 59΄, 12˝-36˚, 24΄, 16˝ latitude from the north. Sampling of the springs was done to determine physical/ chemical features such as total desolved mineral materials (TDS), electrical conductivity (EC), acidity (pH), temperature, taste, odor, quantity of lead (pb2+) and cadmium (cd2+) cations. Comparison of average TDS of the spring indicates that more mineral materials were desolved in the spring No.1 . The cations concentrations were measured by atomic absorption device. Results of statistical study of the data (with the aid of SPSS application) indicated that there was no significant difference between concentrations of lead/cadmium cations in three Springs and sampling site would not affect average concentration of the two cations, therefore, there is a statistical relationship between lead (x) and cadmium (y) cations. But there is no relationship/correlation between lead/cadmium cations and the temperature of springs. Results of  statistical study of the data (with the aid of SPSS application) indicated that there was contamination of lead/cadmium cations in the three springs considering the standard allowable quantity of cations for lead (0.05 ppm), cadmium (0.01 ppm), declared by the Department of the Environment.
