Why is diesel exhaust so toxic?

In 2017, Dr. William Lambert testifies before the Oregon state senate's committee on Environment and Natural Resources about the unique toxicity of diesel exhaust, and why it warrants controls above and beyond other pollution standards.

It is not safe. the exhaust is a threat to human health and the environment. It should be regulated to protect the citizens from exposure. Regulating would save lives and improve quality of life.

.1 micron of what particle, what chemical, what gas? I can say there's .1 microns a particle but that's still just a particle size which is pretty finite but doesn't relay that quanity of particles per million, usually measured using a volumetric unit. .1 microns or sulfur is what would naturally be in the air in some regions with dry slighlty windy conditions where the dirt contains sulfur which is most of the Earth. So saying there's 0.1 micron of a particle contains no factual evidence of anything pertaining to diesel exhaust.

I think worrying about this stuff does more damage to your health than the diesel exhaust does.
