Abstract :
In this study, physical and chemical parameters of Behesht- e- Masoumeh wetland water in Qom province, Iran, was studied. For this purpose six points of the pond were sampled, in winter of 1393 followed by summer of 1394. Variables included: temperature, electrical conductivity, salinity, turbidity, nitrite, nitrate, sulfate, phosphate, aluminum, iron, potassium, TDS, pH, BOD and COD. Results showed that the mean concentration of nitrate in summer and in winter were 2.96±2.19 and 0.98±0.78 mg per liter, respectively, hence, nitrate concentration in summer was almost 3 times more than the concentration in winter. Mean concentration of phosphate in summer and winter were 8.21±14.52 and 0.19±0.15 mg per liter, respectively, showing that the phosphate concentration in summer was 43 times more compared with winter. The average of salinity in winter and summer were 11.87±5.59 and 78.38±77.13 mg per liter, respectively. Winter BOD average was 5.68±3.27 mg per liter while in summer was 15.93±14.59. COD average in winter was 45.3±35.69 mg per liter, while in summer was 667.83±921.63 mg per liter. Aluminum average in winter was 0.038±0.0197 mg per liter while in summer was 0.012±0.019 mg per liter. Iron average in winter was 0.08±0.05 , while in summer was 0.309±0.33 mg per liter. The results showed that the levels of all measured parameters including COD, BOD, turbidity, nitrate, phosphate, nitrite, aluminum and iron in winter and levels of turbidity, nitrate, nitrite, aluminum, iron and BOD in summer were less than the limits of national standards of I. R. Iran for wastewater. However, activity, expansion and development of centers like Behesht -e- Masoumeh cemetery and industrial units, can reduce the water quality of Behesht-e-masoumeh pond, by increasing pollution load in surface and underground water and increasing air pollution, too.
