Možnosti zlepšování životního prostředí územní samosprávou na příkladu snížení koncentrace prachových částic PM10 v ovzduší
Environmental Improvement Possibilities for Local Governments: Example of Reducing PM10 Concentration in Air

Summary/Abstract: The municipality can significantly improve the air in its territory by regular cleaning of itsstreet network. The aim of this study is therefore to demonstrate the positive effect of machinecleaning of roads on the reduction of PM10 dust particles in the air. These particles arethe result of emissions from transport and more than 83% of them come from the so-calledresuspension (the secondary whirling of particles that lie on the road). Cleanliness andcare of public spaces, in which road cleaning may be included, belongs to the so-calledcompulsory tasks of self-governments in some legal regulations, e.g., Bavarian, Polish,Slovak and Serbian, and as this study shows, its positive effect is measurable, which is notcommon among activities of local municipalities. Therefore, it may be stated that the fundsinvested by local governments in mechanical road cleaning have a significant positive effecton reduction of PM10 particles in the air and thus on the health of their citizens. The studyis based on measurements performed in the capital city Prague from 2013 to 2019 and usesmonthly data from 4 measuring stations, for which it was also possible to obtain adequatemeteorological data of variables that affect the occurrence of PM10 particles in the air.The results of the study can be used to properly set up the machine cleaning system so thatits effect is as high as possible. Stata econometric software was used for the data analysis.The study builds on similar analyses carried out in recent years in Europe, the Arabianpeninsula and Asia
