Dust Emission Monitoring in Cement Plant Mills: A Case Study in Romania

International Journal of Environmental Research and Public Health

This paper presents aspects of monitoring material dust emissions from stationary emission sources (monthly dust measurements performed on cement mill stacks—mill outlet and separator outlet). Additionally, the Portland cement mill technological process (its component parts), as well as the solutions regarding the reduction of the air emissions level, following the emission limit values (VLE), established in the integrated environmental authorization (AIM) from a cement factory in Romania, were analyzed. The paper focused on analyzing the data obtained in three different years for PM10 and dust concentrations (2018–2020). For each year, the measurements have been done in 3 months, each in a different season. The average values for each year for working conditions were: 30.22 mg/m3 (2018), 27.38 mg/m3 (2019), and 27.51 mg/m3 (2020) for working conditions and for normal conditions: 34.22 mg/m3 (2018), 30.49 mg/m3 (2019), and 30.16 mg/m3 (2020). For all 3 years, the values measured in ...

Chemical composition of industrial aerosol in some regions

In this paper we discuss the data on chemical composition of aerosol emitted by enterprises in some regions during 1990-2004. The larger half of airborne surveys was carried out in 1990-1992 over largest industrial centers of Russia and Kazakhstan (Nizshnii Tagil, Khabarovsk, Nizshnevartovsk, Komsomolsk-na-Amure, Ulan-Ude, Pavlodar, Ust-Kamenogorsk, etc.). The data were obtained by collecting air samples from the emission plumes from onboard the Antonov-30 airborne-laboratory "Optik-E". Almost all elements and ions to be determined are found in the plant emissions. Concentrations of one or another component can differ by 5 orders of magnitude, what is probably indicative of the properties of the fuel used or the technological peculiarities. The enhanced content of Si, Ca, Al, Mg, and Zn in ashes fraction is characteristic of the enterprises in Khabarovsk and Pavlodar, which used coal during the period of measurements. In addition, high concentration of the water-soluble fr...
