diesel fuel emissions

Quick Reference

Combusted diesel fuel often contains a high content of particulate matter, as well as noxious and toxic fumes, including several known and probable human carcinogens, irritant aldehydes, heavy metal contaminants (lead, mercury), and sulfur. Diesel-powered vehicles are a major source of fine particulate matter in urban outdoor air. Stagnant air in densely populated urban areas with many buses and heavy transports may be so loaded with toxic emissions as to present a real danger to health.
