It didn’t look like a study in air pollution. It only took a few minutes, year after year after year. Once a year, select students in schools across southern California, were taken out of class, marched down to a gym or empty classroom and were met by a researcher. There, they were asked to blow into a spirometer, which measured lung capacity, and were asked a series of mundane questions about their living environment. Then they got their height and weight checked before heading back to class.
Little did they know the data collected from all those children—12,000 kids in all—created the framework for the most extensive study into the effects of air pollution.
Air Pollution effects growing lungs
The USC Children’s Health Study found that children living in the towns most effected by air pollution were five times as likely to have weakened lung capacity—20 percent weaker—than kids living in towns and cities where air pollution was less prevalent. That diminished lung capacity meant long-term health problems.
What’s more, researchers found their original hypothesis was incorrect.
At the start of the study, they thought ozone, a component of the air pollution and thick smog that blankets southern California, would be a prime cause of stunted lung development in the children. However, they found there were a combination of tiny airborne pollutants—small as PM2.5—and nitrogen dioxide from car exhausts to blame also.
Long term implications & treatments
The study has had far-reaching implications on air pollution and has affected everything from manufacturing regulations to environmental policy. It also has created significant awareness regarding outdoor and indoor air quality. In fact, given that indoor air has been proven to be between two to five times more polluted than outdoor air, one might argue that concerns about indoor air quality should be even greater.
Luckily, there is a way to significantly decrease those concerns. The complete line of AeraMax Professional commercial-grade air purifiers can effectively and efficiently remove PM2.5 airborne pollutants—like germs, allergens, bacteria, viruses and volatile organic compounds—from enclosed spaces, drastically improving indoor air quality. The purifiers use a unique four-stage filtration system that traps these particles, removing 99.97 percent of pollutants from indoor air.
The AeraMax Professional purifiers employ patented EnviroSmart™ Technology that senses sound, motion and odors in a room, automatically adjusting to optimize performance. So, the units work only when required, conserving energy and maximizing operations while working in the background to improve the lives and health of occupants.
