RESEARCH BASED ON THE CONCENTRATION OF PARTICULATE MATTER FROM DIFFERENT LOCATIONS OF CONSTANȚA

In this paper, we propose to analyse the air quality in the urban environment, respectively in the city of Constanta. The sources of pollution are multiple, both for the air outside and for the air inside: solid and liquid particles, gas emissions from vehicle exhaust, from industrial sources, cleaning products. All these sources of pollution constitute a real danger for human health, some being even toxic. 4 locations were chosen for measurements and the concentrations of PM2.5, PM10 particles were measured, after which the risk level was established in the period April-May 2024, comparing the data with those provided by the National Environmental Protection Agency. The analysed results show that the quality parameters for PM2.5 and PM10 particles in the outside air have a moderate impact on the environment, while for the premises they are within accessible limits.
