Study associates ozone exposure at birth to increased risk of developing asthma

Green Car Congress

A long-term study of the health of Canadian children has found that exposure to ozone (O 3 ) at birth was associated with an 82% increased risk of developing asthma by age three. For this part of the T-CHEQ study, 1,881 children were followed from birth to 17 years of age, on average. Resources.

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). Preliminary global mean CO 2 concentrations in February 2014 were 398.06 Ozone formation. Scenario A2 and RCP 8.5.
