Particulate Air Pollution and Its Impact on Health in Vilnius and Kaunas
Material and Methods. For risk estimation, the methodology of health impact assessment was employed. The exposure was defined as annual PM2.5 levels for long-term exposure effects and daily PM10 averages for short-term exposure effects. The baseline mortality/morbidity data were retrieved from health registers and exposure-response relationships from previous epidemiological studies. For health impact calculations, the WHO-developed tool AirQ was also applied.
Results. The annual average concentration of PM2.5 was 11 μg/m3 in Vilnius and 17.5 μg/m3 in Kaunas. The exposure above the natural background corresponded annually to 263 (95% CI, 68– 464) and 338 (95% CI, 86–605) premature deaths in Vilnius and Kaunas. This resulted in 3438 (95% CI, 905–5952) and 3693 (95% CI, 983–6322) years of life lost and in an average decrease in life expectancy of 0.43 (95% CI, 0.11–0.74) and 0.69 (95% CI, 0.18–1.19) years, respectively. In addition, 143 (95% CI, 86–200) and 129 (95% CI, 78–179) respiratory and 297 (95% CI, 188–377) and 267 (95% CI, 169–338) cardiovascular hospitalizations per year could be expected in Vilnius and Kaunas, respectively.
Conclusions. There is substantial exposure to particulate matter in the main Lithuanian cities, which causes considerable adverse health effects. Traffic and domestic heating are considered locally the most important contributing factors to the degradation of air quality.
