Abstract

BACKGROUND AND OBJECTIVE: Long-term respiratory risks following exposure to relatively short periods of poor air quality early in life are unknown. We aimed to evaluate the association between exposure to a 6-week episode of air pollution from a coal mine fire in children aged <2 years, and their lung function 3 years after the fire. METHODS: We conducted a prospective cohort study. Individual exposure to 24-h average and peak concentrations of particulate matter with an aerodynamic diameter <2.5 μm in diameter (PM2.5 ) during the fire were estimated using dispersion and chemical transport modelling. Lung function was measured using the forced oscillation technique (FOT), generating standard..
