Health impact assessment (acute chronic CVD and RSD) of ambient air ??10 and PM 2.5 of Ulaanbaatar city

Abstract

Purpose: To determine the relationships between air pollutants (PM10, PM2.5, NO2 and SO2) and meteorological parameters (average temperature, humidity, and wind speed) with acute and chronic respiratory and cardiovascular disease admission of all secondary level and tertiary level hospitals of Ulaanbaatar and 8 primary level hospitals of Mongolia. Method: This is cross sectional survey which collected data (above mentioned air quality and health data) during 1 year and 5 days or 370 days from 1 June 2008 to 5 of June 2009. Results: Relative humidity, PM2.5 level, SO2, NO2 and PM10 level were directly correlated with acute respiratory system disease admission cases. Whereas, PM10, PM2.5, and SO2were directly correlated with acute cardiovascular disease admission cases. The direct correlation with total acute disease admission cases was observed between sulfur dioxide, PM10 level and PM2.5 level. The direct correlation of both chronic disease admission cases with PM10 level was observed. Also direct correlation between PM2.5 level with chronic respiratory system disease admission and PM2.5 level with total chronic disease admission were determined correspondently. Acute disease admissions were more effected to the same day and it was more influenced than the chronic disease admission. Conclusions: PM2.5 exposure for the respiratory and cardiovascular system chronic disease admission was significantly higher than the PM10 level. There are significant correlations between respiratory and cardiovascular morbidity with PM2.5, PM10, NO2, SO2 and some meteorological parameters
