carbon monoxide, nitrogen dioxide, and PM
2.5
were associated with alterations to these two genes and those alterations were significantly associated with asthma.

prevent the damage caused by air pollution particles
that can lead to asthma, chronic obstructive pulmonary disease (COPD) and lung cancer, Bilstein said: “Damage cannot occur as strongly and there is less inflammatory response, and so disease progression is reduced.
Why is ozone bad for asthma?
In these studies, ozone has been demonstrated
to worsen airway inflammation
, to increase the airway response to inhaled allergen, and to increase nonspecific airway responsiveness, each of which is likely to indicate worsening asthma.
Who is at risk of negative health effects from bad air quality?
The groups most affected by air pollution are
people of color, elderly residents
, children with uncontrolled asthma, and people living in poverty. Vulnerable populations may experience more health effects because these populations already have higher rates of heart and lung conditions.
