Recent research has highlighted concerns that potential adverse health effects could be associated with cleaning activities. Indoor air contains a complex mixture of chemicals: it is challenging to determine which species are responsible for the observed health effects. A detailed chemical model has been used to investigate the chemical composition of indoor air following cleaning activities using a limonene-based product. The results show that the gasphase composition is dominated by multi-functional carbonyls (72%), with smaller contributions from species containing peroxyacetyl nitrate (16%) and alcohol groups (5%). The secondary organic aerosol composition is dominated by peroxide (73%) and organic nitrate containing species (18%). Few health benchmark data exist for limonene-oxidation products. For three multi-functional species where data do exist (IPOH, 4-AMCH and 4-OPA), concentrations are unlikely to be harmful following cleaning in this study. However, indoor measurements of these species, as well as further health benchmark data would be beneficial.
