New Research on Trees and Air Quality

New Tree Researchers at the University of North Carolina at Chapel Hill are shedding some light on an air quality mystery that has had scientists stumped for some time.  While we know that plants have a positive effect on air quality by helping to remove carbon dioxide from the air and providing us with oxygen, scientists had long suspected that isoprene, a molecule emitted by trees as a means of protecting their leaves from harm, played a part in creating particulate air pollution; they just were not sure how.   Surprisingly, the study found that when the isoprene molecule was heated by the sun, it reacted with nitrogen oxides in the atmosphere to create tiny particulate matter that became suspended in the air, which has the possibility to cause or exacerbate respiratory ailments, such as asthma.

But wait! Don’t blame the trees for these dangerous particulates – it is the abundance of nitrogen oxide that is the real problem. These polluting chemicals are man-made by-products of cars, factories, and other coal burning sources.  The more that scientists investigate the ways that particulate pollution occurs, the more effective our efforts at improving our air will be.  Over the past decade many major cities in the United States have been able to improve their air quality, but smog and ozone remain in much higher concentrations than what is healthy.  We can help to continue reducing these levels by being mindful about our daily choices – for example, making efforts to carpool or switching from plastic bags to reusable canvas ones. As we work on decreasing the amount of pollutants emitted into the atmosphere, we can protect ourselves from particulate matter by monitoring city air pollution levels before leaving the house, and by filtering particulates out of our indoor air by using an air purifier with a true HEPA filter like our MinusA2.
