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...

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...

Volatile organic compounds produced by industrial activities are harmful to human health and environment, playing an important role in environment quality, but especially in air quality. The main issues raised by presence of volatile organic compounds in the environment are ozone depletion, ozone photochemical formation at ground level, increased global greenhouse effect, carcinogenic effects, toxic and other health problems. The paper presents a case study conducted at an economic operator dealing with treatment ...
