Abstract Background Air pollution is a major cause of premature death and disease, and is the single largest environmental health risk. Heart disease and stroke are the most common reasons for premature death attributable to air pollution, followed by lung diseases and lung cancer. This report aims at investigation and comparative analysis of air pollution and mortality related indicators in Bulgaria. Methods Descriptive study design with content analysis is applied on data from accessible national and international databases and publications - Bulgarian National Statistical Institute and The European Environment Agency. To evaluate the health burden attributable to air pollution were used the population-weighted concentration and the estimated number of attributable premature deaths, and the Years of life lost (YLL) per 100 000 inhabitants in 2016. The Ambient Air Quality Directive defines the PM2.5 Average Exposure Indicator which reflects population exposure to PM2.5 and shows the average concentration at urban areas, calculated as a 3-year average. Results In 2015, the level of PM2.5 had to be below 20 µg/m3 in any country. In 2017, concentrations were still above that level in three countries - Slovakia 22, Poland and Bulgaria 24. The largest health impacts in terms of premature deaths and YLL, are observed in central and eastern Europe where the highest concentrations are also observed - Kosovo, Serbia, Bulgaria, Albania and North Macedonia. The premature deaths attributable to PM2.5 exposure in Bulgaria are 13 100, to NO2 - 1 100 and to O3 - 280. The YLL attributable to PM2.5, NO2 and O3 exposure are respectively 1858, 151, 42. All these levels are very high in comparison with other European countries. Conclusions Recognition of the full health and economic cost of air pollution and the benefits of pollution reduction should spur increased use of renewable energy, energy efficiency, and clean-fuel vehicles. This is a necessary investment for Bulgaria's future. Key messages Responsibility for, and tools to tackle, many environmental determinants of health lie outside the direct control of individuals or the health sector alone. Wider societal, intersectoral and population-based public health approach is needed.
