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.
