A study in Sofia, Bulgaria, performed by Petar Zhivkov and Alex Simidchiev found a correlation between air pollution and morbidity.

The team utilized data from the hospitals Pirogov and Tokuda and the Emergency Medical Service, and found that in days where PM concentrations exceeded the World Health Organization (WHO)'s Air Quality Guideline, target medical checks increased with 60% for Pneumonia, 47% for Infections of the higher respiratory tract, and 36% for COPD.

Furthermore, hospitalizations for more severe cases increased with 59% for Pulmonary embolism, 19% for Heart failure, 9% for Strokes.

Measuring the impact is the first step in improving air quality. The second step is measuring the pollution distribution. We can help cities with that!
