Numerous studies have shown that people living near highways and heavily congested areas may experience the impact on air quality, but even those who live in suburbs or quieter regions need to be aware of the potential for pollution. A recent study, published in the journal Environmental Science Processes and Impacts, looked at how idling cars and school buses affected air quality around public schools in Cincinnati.
The research found that pollution in areas around schools may be measurably greater due to idling vehicles, and that poor air quality may have a negative impact on schoolchildren.
"Anti-idling campaigns are frequently attempted to improve air quality, but until now, no one has evaluated how effective they are," said Dr. Patrick Ryan, the lead author of the study. "The results of this study demonstrate, for the first time, that not idling is a simple and effective policy that can improve air quality at schools, especially schools with a large number of buses."
While this study focused on idling outside schools, homeowners may also be concerned about how vehicles are impacted their environment. Investing in medical-grade air filters like the IQAir GC MultiGas may help to clear the air in a home, and could provide some peace of mind for Americans regardless of where they live.
