Hell, mallposi; we are all still wating on the proof over Iowa's nitrogen in the Gulf. You haven't even furnished that yet. Why haven't you done the same studies on nitrogen in the Great Lakes? (While you breathe it in and out everyday!)
I'm not sure what I'm supposed to do with your new found information that we breathe nitrogen. Should I be worried about it? Should I get an oxygen tank? Should I hold my breath. Should I check for vegetation in my lungs? Should I see a doctor?
