Lung function may recover after coal mine fire smoke exposure: a longitudinal cohort study.

ABSTRACT:

Background and objective

The 2014 Hazelwood coal mine fire exposed residents in nearby Morwell to high concentrations of particulate matter <2.5 µm (PM_2.5) for approximately 6 weeks. This analysis aimed to evaluate the long-term impact on respiratory health.

Methods

Adults from Morwell and the unexposed town of Sale completed validated respiratory questionnaires and performed spirometry, gas transfer and oscillometry 3.5-4 years (round 1) and 7.3-7.8 years (round 2) after the fire. Individual PM_2.5 exposure levels were estimated using chemical transport models mapped onto participant-reported time-location data. Mixed-effects regression models were fitted to analyse associations between PM_2.5 exposure and outcomes, controlling for key confoun
