Impact of ventilation and recirculation rates on exposure to and intake of ozone and its initiated chemistry products: Mass balance model evaluation

A mass balance model is used to examine the impact of two ventilation (1 /h and 2 /h) and recirculation (7 /h and 14 /h) rates on concentrations, exposure to and intake of ozone (of outdoor origin) and secondary organic aerosols (SOA) derived from the ozone initiated chemistry in indoor environment. Measured data from several experimental studies conducted by the authors in a 236m3 field environmental chamber (FEC) configured to simulate an office are used for the mass balance model evaluations.

Confined environments are indoor spaces which are not ventilated or few ventilated due to specific use (shelters, submarines …). In such environments, homogeneous and heterogeneous chemistry are expected to play a key role in indoor air quality (IAQ). The
