How's the (cough cough) Ozone Level?

I just read an interesting article in The Daily Record about new ozone limits. The Record reports that the U.S. Environmental Protection Agency issued a mandate Wednesday to increase restrictions on ozone limits in the atmosphere, placing 11 of the 12 Maryland counties monitored for air quality in violation of the new health standards. Only Garrett County made the cut.

Here's what caught my attention: Harford has the state’s worst recorded ozone level at 93 parts per billion. Susan Kelly, Harford's director of the Bureau of Environmental Health said the area suffers from transport winds from the Ohio Valley.

Is that why I had to get an inhaler and was diagnosed with asthma when I moved here? (Even though I'm originally from the Ohio Valley?) Also, is part of the ozone problem caused by what's being blown up at APG while I'm writing?
