New research sheds light on health risks of smog on young adults

According to a new study, conducted by U.S. Environmental Protection Agency (EPA) and the University of North Carolina Chapel Hill, ozone, the major component of smog, damaged the lung tissues of healthy young adults exposed in a laboratory setting despite being at levels well below what is currently considered safe.  This new information provides a strong warning that people with asthma or other lung diseases, including children and older adults, face even greater health threats from this most common air pollutant.
