Abstract
Introduction. One way to protect atmospheric air from industrial pollution is the use of environmental protection technologies aimed at emissions purification. As a result of the man-induced impact, the industrial emissions can change the composition of air medium, while the resulting products of physical and chemical transformations with other, sometimes more toxic properties, can influence on the quality and chemical safety of atmospheric air in comparison with the initial substances entering it as part of industrial emissions. Materials and methods. Studies of the impact of various technologies of treatment the industrial atmospheric emissions of organic glass and polymer materials processing plants with laser systems were carried out using a chromato-mass spectrometric system Focus GC with DSQ II (USA). Results. We have established the change in the qualitative-quantitative composition of emissions from organic glass laser treatment processes using various cleaning devices. Estimation of electrostatic purification technology efficiency based on plasma-catalytic oxidation with atomic oxygen revealed an increase in the transformation products - aldehydes. The cleaning devices seems ineffective and chemically unsafe concerning one of the primary pollutants included in the emissions of organic glass and polymer materials processing plants with laser systems - methyl methacrylate. Conclusion. The use of new environmental protection technologies for emissions purification can cause a change in their qualitative-quantitative composition, which requires chemical-analytical control. It is advisable to use chromatography-mass spectrometry to identify and quantify up to 100 substances simultaneously in the air with an unknown composition of pollutants to assess the efficiency and chemical safety of new technologies for emissions purification adequately. It will certainly reduce and minimize health risks and allow considering the possibility of man-induced formation of transformation by-products.
