Dust sampling equipment exhibits significant variations over time depending on the operating principle, being influenced by interaction of environmental factors, such as air flow velocity, relative humidity, ambient temperature and barometric pressure. The objective of this study is to perform a comprehensive comparative evaluation between the gravimetric reference method and the optical method for determining PM10 particles in ambient air. In order to allow the evaluation of each observation in relation to method...

The mobile environmental laboratory was located in a fuel distribution station located on a heavy traffic national road in Petro?ani City, Hunedoara County (Romania) to investigate dust and gas pollution, as well as dispersion of pollutants to nearby homes, using the AUSTAL VIEW software. Measurements were performed over a period of eight hours in two working days in order to better capture the movement of air masses and the dispersion of measured pollutants. In the event of accidental spills of chemicals or chemi...

Waste is not only an environmental problem, but an economic loss because Romania recycles only a small part of municipal waste. The use of atmospheric pollutant dispersion models has become necessary due to cost-efficiency reasons, given the limitation of fixed measuring points/stations for these pollutants. The paper studies the dispersion of PM10 dust particle pollution in the landfill?s area of influence, depending on wind direction and speed. Simulations are based on measurements of suspended particles, carrie...
