The article I found for this week is entitled "Air Pollution May Be as Harmful to Your Lungs as Smoking Cigarettes, Study Finds". According to the article, exposure to air pollution causes similar changes in the lungs as changes obtained via smoking that cause emphysema. Exposure to even slightly elevated levels of pollution can accelerate lung damage, even in those who have never smoked. This is especially concerning in areas like the Bay Area where air pollution levels are particularly elevated. Patient education regarding reducing exposure to air pollution is crucial, especially in highly populated areas. Indoor air filters can be used at home to reduce indoor exposure. Wearing an N95 mask while outdoors may help reduce exposure to certain particulates.
