Abstract

Results of experimental studies are reported on the substantiation of the maximum single permissible concentration (MAC maximum single) of volatile organic compounds, formed during a high temperature processing of wood in chipboard production (based on tererpene hydrocarbons), in the atmospheric air of residential areas at the level of 0.05 mg/m3. The magnitude was established on the basis of olfacto-odorimetry taking into account new approaches to the determination of «obsessive» odor thresholds as a limiting criterion for the MAC maximum single justification in accordance with the international practice of setting odor limits and our home experience gained in the standardization of odorous substances in the ambient air. The selection of priority substances for the control of the designed value (α-pinene, β-pinene, 3-carene, limonene, camphene) was based on the analysis results of the composition of releases from a high temperature processing of wood and atmospheric air in the enterprise location area.
