The study also identifies associations between exposure to the two pollutants and molecular changes in the children's airways during non-viral asthma attacks, suggesting potential mechanisms for the attacks. The observational study is one of the first to link elevated levels of specific outdoor air pollutants in particular urban locations to distinct changes in the airways during asthma attacks not triggered by respiratory viruses, according to the investigators. The findings were published in the journal The Lancet Planetary Health.
