BACKGROUND
In recent years, many researches that is related to waterborne diseases, especially diarrhea and water quality, safety, personal sanitation, hygiene have been conducting in developing country. Kharaa and Orkhon river are tributaries of the Selenge river basin and the many industries, agriculture, mining, provinces, soums are located in the near of Selenge river basin. Also Tuul, Kharaa and Orkhon river water is very polluted (Mongolian human Development Report 2010: Water and Development report).
AIM
The aim of the research is to study correlation between to Kharaa and Orkhon river’s water pollution level and rate of gastrointestinal infectious diseases of people who live in the near of Selenge river basin.
METHOD
We analysed Kharaa and Orkhon river’s water quality and statistical data of gastrointestinal infectious diseases (such as dysentery, diarrhea, hepatitis A virus and others). Then we conducted correlation analysis between to river water pollution level and rate of intestinal infectious diseases.
RESULT
Kharaa and Orkhon river’s water was determined “less polluted” by physical, chemical and organic indicators. But total number of bacteria was determined highly and Proteus vulgaris, Citrobacter freundi, Enterobacter agglomerans pathogens were detected in these river’s water.
CONCLUSION
There were significant positive correlations between level of nitrit in river water and incidence of dysentery and diarrhea. (r=0.38, p=0.022; r=0.291, p=0.005).
