[Harmful substances released during the thermal oxidative destruction of coolant lubricants].

The use of lubricated oils in industry is related to processes of dispersing, evaporation and thermo-oxidizing destruction. As a result, in the air is eliminated a complex vaporous-gas aerosol mixture, consisting of lubricated aerosols, vapours and volatile products of evaporation and products of thermo-oxidizing destruction. In the vapour-gas phase are identified hydrocarbons [saturated, unsaturated, aromatic and cyclic] oxygen- containing hydrocarbon derivatives-aldehydes, ketones, esters, alcohols] in some cases CO. HCL. The composition of the mixture depends on the type of the lubricated oils and on the specific technological operation. The detailed study of the components of the mixture is a prerequisite for determining the leading toxic substances and for correct evaluation of the exposure and professional risk in industries, allowing a course of destructive processes with the lubricated oils.
