RESPIRATORY DISEASE, INFECTIONS
Exposure to wood smoke from incomplete combustion did not induce any acute inflammatory cell influx detectable in BW or BAL at 6 h, apart from eosinophils. Instead, there were signs of early cytotoxic reactions with increased LDH, reduced cell viability and impaired alveolar macrophage phagocytic capacity. These findings are in accordance with the preceding bronchoscopy study with sampling at 24 h, as well as in vitro cell data. Our findings provide some evidence for the increased susceptibility to infections and worsening of respiratory diseases by biomass smoke exposure, as reported in population-based studies [
