Vincent Carroll of the Rocky Mountain News, cited a study from two California researchers and Doug Lawson from the Nation Renewable Energy Labs in Golden regarding an interesting fact about Denver's ozone levels. It seems that the levels are higher on the weekends than on the weekdays.
Seems odd, right? But what they found is all about chemistry.
But as Lawson points out (and as he and others have explained in previously published research), the mix of pollutants may be at least as important as their total quantity.
So while there are fewer hydrocarbons polluting the air on Sundays than on Wednesdays, the decline in nitrogen oxides(NOx) is even steeper because so many diesel trucks and buses are off the road. Here is a great idea; let's figure out the effects of our emesis programs placed on the automobile and diesel engine industry
before we enact them!
You have to sign up to read the study, which I may or may not do later. Of course I feel it should be made public, but that would not make them any money I suppose.
