Influence of meteorological conditions on the variability of indoor and outdoor particulate matter concentrations in a selected Polish health resort.

ABSTRACT: The article evaluates air pollution by particulate matter (PM) in indoor and outdoor air in one of the Polish health resorts, where children and adults with respiratory diseases are treated. The highest indoor PM concentrations were recorded during the winter season. Therefore, the maximum average daily concentration values in indoor air for the PM₁₀, PM_2.5, and PM₁ fractions were 50, 42 and 23 µg/m³, respectively. In the case of outdoor air, the highest average daily concentrations of PM_2.5 reached a value of 40 µg/m³. The analyses and backward trajectories of episodes of high PM concentrations showed the impact of supra-regional sources and the influx of pollutants from North Africa on the variability of PM concentrations.
