Kurt, that soot is more dangerous than you might think. I always thought it was mostly carbon.
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.
