Relationship between outdoor and indoor ozone pollution concentration

Abstract

This paper analyses the changing rule of indoor ozone concentration and its influencing factors. A formula of indoor-outdoor concentration ratio (I/O ratio) was deduced based on the indoor ozone mass-balance equation. The ozone I/O ratio in different kinds of buildings was studied. Results show that I/O ratio is much related to air-exchange rate, which is well compatible with the theoretical calculation results.

Keywords
