Abstract

Introduction: Nitrite (NO2) and Nitrate (NO3) compounds are the pollutants in ground water and due to developing of agriculture and man's activities, their average rate is increasing: These materials are absorbed rapidly in the first parts of small intestine and then enter the blood. In blood, NO2 is changed into NO3 and through a process Hb is changed into methemoglobin and Hb is unable to join with O2 and CO2, as a result O2 can not be transferred into tissues and lungs.Objective: This study aimed to survey the level of Nitrite and Nitrate in Semnan drinking water resources in 2002.Materials and Methods: In this research, the rate of NO2 and NO3 in Semnan drinking water was measured in all seasons using Spectrophotometer DR 2000has. Sampling was performed in all drinking resources in Semnan city (120 samples).Results: Nitrite concentration measurement in spring was higher than the WHO’S standards (0.2 ppm) in all resources. This variable was also higher in well NO.1 in the east north and also the Seda-o- Sima's well which was more than the WHO’S instructions. In autumn, the NO2 concentration rate in Seda-o-Sima’s well was higher than the WHO’S standard. In winter, it was less than WHO’S standard. Nitrate concentration in Seda-o-Sima's well in spring was in the classification of the polluted waters 26 ppm and the rest of sources were considered as little polluted less than 20 ppm In summer all resources had little polluted water. In fall, the Seda-o-Sima’s well was polluted (22 ppm). In winter, all of them were little polluted.Conclusion: In attention to the categorization of little polluted water with nitrate less than 20ppm, all drinking water resources in Semnan except Seda-o-Sima's well, in all seasons were considered polluted. While Seda-o-Sima’s well, all categorized as polluted water in spring and autumn, but in summer and winter Seda-o-Sima’s wells categorized as little polluted. Also Seda-o-Sima’s well is more polluted with nitrite and nitrate in comparison with the other Semnan drinking water resources.
