Abstract
The assessment of the air pollution quality in selected sites of Silesian Voivodeship was presented in this paper. The evaluation based on the sets of long-term data, recorded by the state air monitoring network. Concentrations of main air pollutants such as PM10, O3, CO, SO2, NO2, NO were considered. The basis for the calculations were 12-year time series of hourly concentrations. Using this data, the monthly averages of pollutant concentrations were calculated. Long-time trends of concentration changes were determined for each pollutant separately. Based on the analysis of trends, risks that may arise in the future were identified.
Highlights
Silesian Voivodeship has the opinion of the most polluted region of Poland
Long-term measurements of the air monitoring stations allow to answer the question how the air quality has changed in these towns
The aim of the study is to identify the trends of changes in the concentration level of main air pollutants
Summary
Silesian Voivodeship has the opinion of the most polluted region of Poland. Long-term measurements of the air monitoring stations allow to answer the question how the air quality has changed in these towns. The aim of the study is to identify the trends of changes in the concentration level of main air pollutants. The present monitoring program started functioning shortly before Poland's accession to the EU [2, 3]. Air monitoring measurements were carried out, but on other principles. In this examination, 2005 was adopted as the starting point in the analysed time series. 12-year observations should allow to determine the real trends. Designing trends allow to identify the air quality hazards that may emerge in the future
