ASSESSMENT OF AIR POLLUTION WITH HIGHLY TOXIC COMPOUNDS IN THE ZONE OF MAN-MADE EMERGENCIES ASSOCIATED WITH THE FIRE OF SYNTHETIC MATERIALS
Detection and control of highly toxic compounds in the environment in case of man-made accidents requires the development of modern techniques. A study of the stages of decomposition of a widespread synthetic polymer-polyvinyl chloride. Chromatographic analysis and mass spectrometry revealed the qualitative composition of gases and vapors contained in the air during thermal decomposition of polyvinyl chloride in the presence of oxygen. In addition to the previously proven hydrogen chloride, the main component of polyvinyl chloride pyrolysis products, other chlorine-containing compounds have been identified that are highly toxic and resistant over a wide temperature range. The conditions of sample preparation using activated carbons are presented.
