The air we breathe affects us no matter who we are or where we live. Even though you can't always see it or smell it, air pollution can affect our health in a variety of ways. Hazy air may be a sign that the air has become more polluted.

Microscopic particles are the prime cause of poor visual air quality, since they absorb and scatter light, resulting in a haze that obscures distant vistas. These same particles can impact your respiratory system (lungs and airways) and cardiovascular system (heart function and blood circulation). Both short and long term exposure to elevated concentrations of these particulates has been shown to be hazardous to health. While air pollution affects individuals in different ways, groups who are especially sensitive or at-risk include children, the elderly, and those with pre-existing cardiac or respiratory diseases.
