A new study finds Wisconsin has made progress in reducing air pollution. However, an increase in asthma prevalence among children and population increases in the counties most affected by the irritants, mean health risks remain high.
Ozone is a colorless form of oxygen that damages respiratory tissues.
Particulate matter may include aerosols, heavy metals and minerals, and can harm lung function. The researchers note that the population at-risk to ozone pollution alone may be as high as 400,000. The study credits the decline of ozone pollution levels to concerted efforts by state, regional and national levels of government. While primary prevention through pollution control is the goal, informed at-risk individuals can take action to minimize the impact of peak pollution episodes, the researchers conclude. The study s lead author is Daniel A. Daggett, PhD, a toxicologist with Wisconsin s Department of Health and Family Services.
