Healthy You: Spring Isn’t the Only Thing in the Air by Kim Jones, Cary Medical Center I love spring in New England. It’s a magical season of rejuvenation when colors emerge from the shimmering shadows of winter, flora and fauna wake from months of slumber, and days grow longer by the minute. One of my favorite ways to welcome spring is to open my windows to let sun-kissed breezes flood my home, office, and car. As refreshing as this is, however, I can’t help but notice that spring isn’t the only thing in the air. Outside, road grime, pollen, and smoke from burning fields all tend to be especially heavy this time of year. And inside, rooms that were sealed up for the winter have accumulated residue from heating systems, dust, and allergens. So, how can we embrace spring without the risk of congestion, eye irritation, scratchy throat, or worse? Let’s start by defining air pollution. Simply put, it is a mixture of natural and synthetic substances in the air. The substances are called pollutants, and they can be in the form of gases, particles, and even liquids. Some pollutants can be seen (like smog or dust), while others are invisible to the human eye (such as ground level ozone or carbon monoxide). Pollution can come from two different kinds of sources – primary or secondary. Primary sources are pollution on their own, emitted directly into the environment from a source. Secondary pollutants form when there is a reaction in the atmosphere by mixing two or more primary pollutions to create a new pollution substance. Regardless of the source, air pollution is considered a major health hazard around the world in that it contributes to the development and severity of conditions such as respiratory infections, eye irritation, heart disease, cancer, and asthma. The World Health Organizations estimates that more than 3 million premature deaths annually can be attributed to poor air quality, with the most affected populations living in developing countries and urban areas. But even when the air looks and smells clean, as it often does in Aroostook County, you could still be inhaling dangerous pollutants that have serious, long-term health consequences. In fact, Maine has among the highest levels of radon (a colorless, odorless, tasteless radioactive gaseous pollutant) in the United States and radon is the second leading cause of lung cancer! Even relatively low concentrations of air pollutants have been linked to adverse health effects, making this a problem that touches everyone in all parts of the world…not to mention the environmental impact, including destruction of plant life and animal deaths. While it’s practically impossible to completely avoid exposure to air pollution, there are several steps you can take to protect yourself and your family from its effects. For outdoor air pollution: 1. Learn how to use the Air Quality Index (AQI). This guide, from the U.S. Environmental Protection Agency, is a daily report of air quality based on the five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. The EPA has established national air quality standards to protect public health. The AQI will tell you what the current air pollution levels are based on these standards.
