The concentrations of volatile organic compounds (VOCs) and carbonyl compounds were measuredat 40 residences in three cities of China (30 from Chengdu, five each from Changsha and Beijing).Indoor, outdoor and personal exposure samples were simultaneously collected at each site. The average concentrations of benzene, toluene, xylene, especially benzene, were significantly higher than those of other countries both indoor and outdoor. There is significant correlation between indoor concentration and personal exposure of VOCs and carbonyl compounds. Mean of indoor/outdoor ratios of VOCs and carbonyl compounds exceeded 1. The relevance between indoor air concentrations of VOCs and carbonyl compounds and interior decoration was studied, it showed that interior decoration materials were significant sources of VOCs and carbonyl compounds in Chinese indoor environment.
