Mongolia is a landlocked country with a total land area of 1,564,116 square kilometers. Ambient annual average particulate matter (PM) concentrations in Ulaanbaatar are 10–25 times greater than national standard. The study aims to define the relationship between ambient air PM2.5 level and hospital admissions during the years 2010 and 2014. Pollution data included the 24-hour average of PM2.5. Data were sampled daily and optioned from the national air monitoring stations located in Ulaanbaatar.The sampling frame of hospital admissions for cardiovascular disease (CVD) were the records of all outpatient hospitals of Ulaanbaatar. Data covers the period from January 2011 to January 2014. To test the differences of the results, appropriate statistical tests were used. During 2011-2014, the highest concentration of PM2.5 occurred during the coldest period of time and the particulate matter level recorded is 3.7 times higher in the cold period than the warm period. During cold periods of time, the most admissions for CVD were registered. Four days after exposure, the PM2.5 impact on hospital admissions was weakened but there remained a positive correlation. For PM2.5, 100 µg/m3 growth of the pollutant led to 0.65% increase in the hospitalization for cardiovascular disease on the exposed day. Second day of exposure, 10 µg/m3 growth of the pollutant led to 0.66% increase;on the third day of exposure,10 µg/m3 growth of the pollutant led to 0.08% increase of hospital admissions for CVD, and at the fourth day,such growth led to 0.6% increase of CVD cases during 2011-2014. In conclusion: Most incidences of CVD registered during the cold months in the last four years were a result of PM2.5 exposure. This shows that PM2.5 exposure and hospital admissions for cardiovascular system chronic diseases are positively correlated. CVD in Ulaanbaatar residents were affected more on the same day and third day of exposure.
