Abstract:
Objective To investigate the characteristics of nitrate pollution and its affecting factors by analysis of the mon i-toring data on ni trate con tent in281specimens of ground water in Haidian District during1990-2000.Methods Nitrate con-tent in the water sam ples and its rela ted factors including area,year and hydrologic period were an alyzed using single factor variance analysis with the STATA4.0statis tic software developed by the Computer Resource Center in USA.Results Among the281specimens collected during1990-2000,nitrate con tent in24specimens were beyond the National Hygienic Standard,substandard rate was8.54%.There was significant difference in the nitrate con tent in the specimens collected from different ar-eas(F=10.02,P0.05).There was no statistically significant difference in the nitrate content of the specimens between low water season and high water season.Hydrologic period was not an influential factor on the changes the nitrate content.Conclusion Regional differ-ence was found in the nitrate pollution levels of water,which indicated that control measures on the nitrate pollution should be taken in some main areas with nitrogen-rich organic substance pollution.
