Diesel Facts

Diesel Exhaust is Primarily Composed of Particulate Matter (PM)

Particulate matter is leftover, unburned carbon from the engine. When inhaled, it permanently lodges deep within the lungs. PM is dangerous, because it has a very rough surface, which bonds easily with other toxins, such as metals and lube oil from the engine. When this happens, PM becomes a vehicle, carrying those toxins into the body.

Exposure to Diesel Exhaust has serious health impacts.

following health problems:

  • Asthma attacks
