DCEG research on the association between indoor air pollution and cancer has informed international regulatory actions on this exposure.
The International Agency for Research on Cancer (IARC) classified indoor emissions from household combustion of coal as an established human carcinogen and emissions from high-temperature frying as a probable human carcinogen following DCEG research that found increased lung cancer associated with smoky coal use (Lan et al., 2002, 2008) and cooking fumes (Gao et al., 1987) in China. The findings also informed the World Health Organization’s WHO Guidelines for Indoor Air Quality: Selected Pollutants.
