Indoor air quality (IAQ) is influenced by a cocktail of air pollutants emitted and formed in situ from a broad range of sources and human activity such as cooking and cleaning. Uncertainties remain in understanding the relationship between human behaviour and air pollutants emissions and dynamics, their emission source strengths and spatial variability in the residential buildings (Braniš et al., 2014; Nazaroff, 2016). A systematic approach to measuring the impact of indoor activities informed by human behaviour is extremely valuable and should allow the extrapolation of experimental findings.
