AB  - Terpenes are VOCs of particular importance, since they are emitted from a wide 
      range of indoor sources and are considered to be precursors of Secondary Organic 
      Aerosol (SOA) formation. It has been proven that SOA particles, especially 
      nanosized ones, pose a threat to human health. In this research, experiments with 
      the application of an environmental chamber and real-time measurement techniques 
      were carried out to investigate in a complimentary way the formation of 
      monoterpene oxidation products and nanosized SOA particles initiated by 
      monoterpene ozonolysis. Proton-Transfer-Reaction Mass Spectrometry with a 
      Time-Of-Flight analyzer (PTR-TOF-MS) and a Scanning Mobility Particle Sizer 
      (SMPS) were applied to determine in real time the dynamism of the formation of 
      the corresponding terpene ozonolysis products and submicron SOA particles. 
      Results proved that firstly, oxidation products were formed, and then, they 
      underwent nucleation and condensation, forming particles whose diameters grew 
      with time. The oxidation products formed were different depending on the type of 
      terpenes applied. The comparison of the results obtained during the experiments 
      with gaseous standard mixtures and real samples commonly present and used in 
      indoor air revealed that the diversified chemical composition of the emission 
      source had implications for both the particle formation initiated by the 
      oxidation of essential oil components and the chemical reactions occurring via 
      the oxidation process. With the instrumentation utilized, the concentration 
      changes at the level of a few ppbv could be monitored.
