Abstract
This paper presents the results of the experimental studies on justification of the maximum single allowable concentrations (MAC) of 1-methyl-4-isopropenylcyclohex-1-ene (limonene), 3,7,7-trimethylbicyclo[4.1.0]hept-2-ene (3-carene), and 2,2-dimethyl-3-methylenebicyclo[2.2.1]heptane (camphene) in the air of urban and rural settlements. The research has been carried out in accordance with the current methodology for determining the odor thresholds of substances using modern olfactometric equipment (dynamic olfactometer) and highly sensitive methods for identifying chemical components (chromatography-mass spectrometry). According to the results obtained, the recommended maximum single allowable concentrations in the atmospheric air of urban and rural settlements are 0,08 mg/m3 (hazard class 4) for limonene; 0,2 mg/m3 (hazard class 4) for 3-carene; 0,3 mg/m3 (hazard class 3) for camphene; the limiting indicator of harmfulness for all substances is reflex. An analytical methodic based on chromatography-mass spectrometry and certified in accordance with GOST R 8.563-2009 and GOST R ISO 5725-2002 has been developed to control the concentrations of α-pinene, β-pinene, camphene, 3-carene, and limonene in the atmospheric air of urban and rural settlements.
