Abstract:
In the need of resources, human activity has resulted in industrial activities that disrupted the delicate equilibria of natural Earth with serious impacts on environmental quality, including air quality alteration, climate change, changes in fundamental biogeochemical cycles. The aim of this study was to analyze the temporal variation of various fractions of aerosols (PM1, PM2.5 and PM10) in a small village close to open-pit coal exploitation in southwestern Romania, in order to investigate the level of particulate matter pollution encountered by the population living in the area. The sampling was performed in a residential area at 10 m over the ground for 12 hours per day during 10 successive days between 5th and 14th April 2018 using two low-volume samplers and an eight-stage low-pressure cascade impactor (size range 0.06-16 µm diameter). Sampling period was chosen in order to cover both working (full time, part-time) and non-working days at the coal exploitation. A check for the compliance to European air quality standards and an investigation of the relationships of aerosol mass concentrations with the air mass back-trajectories and meteorological parameters were also performed. The PM atmospheric concentrations captured the level of exploitation activities in the area. Results show systematic exceedances of the air quality limit values. Aerosol particles present a bimodal size distribution with two maxima in the size ranges of 0.125-0.5 µm and 2-8 µm, and smaller aerosol fractions dominate during exploitation activities.
