Abstract

In this study, it is aimed to investigate the presence and levels of nitrate and nitrite in potable waters in Mardin. Totally 118 water samples, taken from 64 taps, 41 wells and 13 water tanks within the city center and districts of Mardin, were used in this study. The analyses to determine the presence and level of nitrate and nitrite in the samples have been performed through spectrophotometric method. The mean value of nitrate level was found as 2.55±3.58 ppm in 31 (26,27%) and nitrite as 0.032±0.091 ppm in 91 of 118 water samples analyzed. The mean values of water samples, in which nitrate and nitrite were found, are respectively 2.49±3.65 ppm and 0.033±0.072 ppm in taps; 2.00±3.09 ppm and 0.035±0.125 ppm in wells; 3.93±4.71 ppm and 0.018±0.017 ppm in water tanks. One (0.85%) of analyzed water samples had nitrite level (0.72 ppm) higher than maximum legal limit. There was not any statistically significant difference in terms of precense of nitrate and nitrite in the analyzed samples of water, taken from taps, wells and water tanks. Although no general risk was found in terms of level of nitrate and nitrite in the analyzed water samples, it is believed that they have to be monitored frequently in order to find of any spontaneous contamination.

Abstract

In this study, it was aimed to investigate the presence and levels of nitrate and nitrite in potable water in Mardin. A total of 118 water samples, collected from 64 taps, 41 wells and 13 water tanks within the city center and districts of Mardin, were used in this study. The nitrate and nitrite analyses were performed by spectrophotometric method. The mean value of nitrate levels was found as 2.55±3.58 ppm in 31 (26.27%) and nitrite as 0.032±0.091 ppm in 91 of 118 water samples. The mean values of nitrate and nitrite were 2.49±3.65 ppm and 0.033±0.072 ppm in taps; 2.00±3.09 ppm and 0.035±0.125 ppm in wells; 3.93±4.71 ppm and 0.018±0.017 ppm in tank water respectively. One (0.85%) of analyzed water samples had nitrite level (0.72 ppm) higher than maximum legal limit. There was no statistically significant difference between the samples taken from taps, wells and water tanks for presence of nitrate and nitrite.According to the results of the study, although a general risk was not determined in terms of nitrate and nitrite levels in the water in Mardin, it is thought that monitoring is important for the detection of individual contaminations.
