Is it possible to see air pollution with the naked eye? Many people assume that pollution is an invisible enemy, but those people would be surprised to find how visible pollution can be in the air. The Missouri Department of Natural Resources offers a unique way to give people a different perspective on air pollution.
Visual Air Pollution Cameras, Urban Areas
The department has air pollution cameras in St. Louis and Kansas City that have an interesting purpose. The St. Louis ArchCam is located on the roof of the Sisters of Mary St. Mary’s Health Center, 6420 Clayton Road in Richmond Heights and the KCCam is on the Blue Ridge Mall office tower. Each camera has its own website that allows visitors to view several pictures of the St. Louis and Kansas City skylines. To view the ArchCam, visit http://www.dnr.mo.gov/env/esp/aqm/archcam.htm and to view the KCCam, visit http://www.dnr.mo.gov/env/esp/aqm/kccam.htm. These sites show pictures of a poor visibility day, a good visibility day and current. The photographs will allow you to see the effects of air pollution on visibility with your own eyes. Although not all air contaminants are visible, these pictures can give you an idea of how the air you breathe can be unhealthy.
What Causes Reduced Visibility?
The main component to reduced visibility is smog. Smog is a reddish-gray fog that occurs when sunlight is mixed with nitrogen dioxide, hydrocarbons and other air contaminants. These pollutants come from anything that burns fossil fuels, such as automobiles, heating and cooling systems and factories. Not only does smog diminish visibility, but it also produces ozone.
Ozone is a chemical that can be a health hazard, especially to children and the elderly. High concentrations of ozone may cause breathing difficulties, an increased risk of bronchitis and aggravated cases of asthma. All of this is caused by air pollution.
