**3.2 Ambient particulate matter and bronchial asthma: Results of the epidemiological study based on a geospatial approach**

In the epidemiological study based on a geospatial approach [35], a statistically significant increase in the incidence of bronchial asthma was revealed with an increase of 0.09 per 100 annually (growth rate of 17.6% per year). The increase in the incidence of bronchial asthma was observed mainly due to the non-allergic phenotype—by 0.011 per 100 population annually, and the mixed phenotype—by 0.034 per 100 population annually; the increase in the incidence of allergic asthma (by 0.028 per 100 population annually) did not reach statistical significance. An increase in the maximal annual concentrations of PM2.5 by 10 μg/m3 increased the absolute risk of non-allergic bronchial asthma by 0.066 per 100 people aged 18–65 years (p < 0.05). For other phenotypes of bronchial asthma (allergic asthma, mixed asthma), no statistically significant relationships with mass concentrations and deposited doses were found.
