It is likely that indoor air pollution derived from the burning of biomass fuels will prove to have similar effects. Also bacterial colonization contributes to the airway inflammation in patients with stable COPD. The degree of inflammation also relating to the bacterial load and to the bacterial species (Hill at et al, 2000). Consequences of such colonization and enhanced inflammation on morbidity and lung function is not clear Hill AT, Campbell EJ, Hill SL, Bayley DL, Stockley RA.
