(American Journal of Epidemiology) The study investigated the effect of indoor air pollution from gas appliances on neuropsychological development in preschoolers. Results showed that use of gas appliances was negatively associated with cognitive outcomes and inattention symptoms, independent of social class and other factors. It suggests that early-life exposure to air pollution from indoor gas appliances may negatively impact neuropsychological development, especially in genetically susceptible children.
