On October 1, the Obama administration released a new environmental regulation concerning smog. For those of you that don’t know, smog is an air pollutant that gets its name from a mash-up of the words smoke and fog. It was first seen in London, where clouds of smoke and sulfur would mix with fog to create a thick haze that would hang over the city. While still associated with coal burning, it is now known that VOCs and airborne particulate matter called ozone can also be responsible. The recent law limits the amount of ozone that can be released from factory smokestacks and tailpipes with the intention of reducing smog.
