Principal types of technogenic impact on the environment, caused by manufacture, storage and operation of the antiseptics impregnated production, are emission in an atmosphere and deposition in a soil-vegetative cover of organic compounds which have harmful effect on organisms, a biomass of plants and create serious ecological, medico-social problems. In Russia coal-tar oil (C?O) (1 class of danger) and a thermocatalitic liquid (TCL) (4 class of danger) are used as antiseptics.

We carry out for the first time the qualitative, quantitative, comparative analysis and monitoring of organic contaminants (OC) in the environmental objects (air, soil, snow) of the zones of influence of the manufactures applying antiseptics. More than 70 names of OC are identified, such as aromatic and polyaromatic hydrocarbons, N - O - S-containing heterocycles and alkanes. It is established that the most exhaustive information is received by using the sorption method of air sampling in a combination with extraction and thermosorption methods of the sample prreparation. It is shown that the most polluted are the shop of impregnation and the warehouse of finished goods. The structure and concentration of OC in environmental objects depend on a type of the used antiseptics and seasonal features of distribution and deposition of the technogenic emissions.

For the first time the chemical composition of antiseptics - (CTO) and TCL - is studied. The comparative analysis of chemical composition and carcinogenic activity of the investigated antiseptics is carried out. For the first time calculation of emissions of organic compounds from the sources of manufacturing connected with application of antiseptics is carried out. It is shown that the major components in emissions are volatile compounds (benzene, benzene derivatives, indanes, phenolic compounds, naphthalene and its derivatives) which share in total emission makes more than 70 %.

Concentrations of organic substances which are part of the antiseptics that give representation about air pollution on an industrial site and in a zone of influence of manufacture are calculated by method of mathematical modelling. The list of priority organic contaminants of the impregnation manufacture including 21 names is defined.

The results obtained have allowed giving the ecological and medico-social characteristics of the industrial enterprises using oil and coal antiseptics, to develop a complex of actions for improvement of working conditions of workers of the enterprise and an ecological situation on manufacture, to organize analytical control of OC in the environmental objects.
