摘要：Air pollution is the result of natural processes and intense urban development.The volatile substances undesired emission causes environmental threats such as acid rain, aggravated greenhouse effect or the ozone depletion.Moreover, the pollution released into the air are harmful to the human respiratory system, eyes and skin.This paper presents the body of analyses conducted in Poznań between 2015-2017 on the changes in the local emission concentration of PM10 and PM2.5.The data concerning the emission of suspended particulates were provided by the meteorological station on Polanka St.in Poznań.The research included correlation analysis.The results point to a steady decrease in the amount of produced particulates.It was also noted that the emissions of PM10 and PM2.5 change seasonally, with the highest levels in the autumn and winter.Furthermore, the amount of emitted suspended particulates is correlated with the temperature, hence it is supposed that the main source of air pollution in Poznań are low-efficiency heaters and boilers.
