TWO, IT BURNS CLEANER THEREFOR CREATING LESS CARBONDIOXIDE THAT CAUSES "GLOBAL WARMING" AND THREE ITS JUST FUN TO DRIVE.

In reference to testing the air in close relation to highways? Thanks. Has anyone heard of testing instruments that can be used to determine specific kinds of diesel pollutants?

Let me try and sort things out here: beth: You may be forgetting that children are WAY more susceptible to environmental toxins than adults. Exposure at young ages can sometimes set up susceptibility to things later on. Matt: When I said highest emissions standards in the world, I was talking about diesel emissions standards (that's what the post is about). There are no diesel SUVs in the US that I'm aware of. Ever been to a Latin-American city? Usually, it's filled with blueish diesel smoke. Even Europe has NOx emissions standards that are six-times lower than the US. Craig: you might want to try reading the abstract again. This study wasn't even looking at the brain, but one type of carcinogen (of many) binding to lung surface cells. It says: "We conclude that the genotoxicity of diesel fuel is based on higher particulate emission rates compared to gasoline emission and although the concentration of PAH compounds was higher in diesel particulate extracts, DNA binding by the gasoline particulate-bound PAH compounds was more pronounced than that by the diesel particulate-bound PAH compounds." All that says is that both diesel and gasoline PAH emissions are bad. No matter what, diesel produces more particulates than gasoline. noway: I'm not sure what kind of scientist you are, but they were talking about oxidative-stress in a region of the brain, not 'stress' like what happens when you have to speak in public. The only thing you're right about is placing the word 'may' before that conclusion, which I just did. But that came from Environmental Science & Technology: "Nanoparticles such as those in diesel exhaust can cause inflammation and an imbalance in highly reactive forms of oxygen, a condition called oxidative stress, in parts of the body where they land after being inhaled. The researchers hypothesize that the effects of diesel exhaust could be caused by nanoparticles slowly penetrating the brain or affecting brain signaling."
