That's great, Allen, but can you point to similar studies on the nanofine and ultrafine particulates emitted unregulated by gasoline engines?
I haven't found any; until the effects of those more persistent particulates are studied in a health context, pinning the blame solely on one or the other is pointless fuel partisanship. Medical studies unrelated to exhaust emissions have shown finer particulates to be both more persistent in tissues and more carcinogenic once there. Additionally they are less likely to be filtered out by the nasal cavity and mucus membranes. Having established that, I feel that an intensive study, like those done on diesel engines, is warranted.

The Clean Air Task Force (CATF) combined NATA data with the diesel cancer risk factor developed by the California Air Resources Board and found it to be three times greater than the risks of all air toxics tracked by EPA combined. The Boston-based nonprofit also found that the average lifetime cancer risk from diesel exhaust to be 159 times greater than EPA's acceptable one cancer in a million standard for air toxics.
