When inhaled, ozone smog can impair lung function, trigger asthma attacks, and aggravate diseases such as bronchitis and emphysema, in some cases leading to premature death. Children, the elderly, and people with existing respiratory conditions are the most at risk from ozone smog pollution, which can drive them to stay indoors in the warmer months when smog levels are highest, robbing children of their summers and others of their ability to work and recreate out of doors. However, the health impacts associated with ozone smog produced by pollution solely from the oil and gas industry have never before been quantified.
