Diesel soot, or particulate matter (PM), is a dangerous pollutant that can penetrate deep into the lungs. People exposed to diesel soot can suffer from severe respiratory and cardiovascular illnesses, chronic bronchitis, cancer, and premature death. California, with the largest population of people and diesel vehicles in the country, is in essence a microcosm of the national health risks of diesel emissions.
