asthma

Air pollutants of all kinds in North Carolina and the United States are at their lowest levels since measurements began back in the 1970s. The weight of the evidence suggests that these low levels of air pollution are at worst a minor health concern.

Summary: During debates about air pollution in North Carolina, supporters of more regulation have asserted that high rates of childhood asthma are related to increasing exposure to ground-level ozone. Not only has there been no such increase, but a new study shows there is, if anything, an inverse correlation — the higher the ozone level, the lower the asthma rate. Next time, lawmakers and the media should check the facts before repeating unfounded and politically motivated allegations.
