Hazards
Soot, particularly diesel exhaust pollution, accounts for over one quarter of the total hazardous pollution in the air, and a disproportionately high share of the load of sickness and death caused by pollution.
Long-term exposure to urban air pollution containing soot increases the risk of coronary heart disease, according to a major study published in New England Journal of Medicine in 2007. Diesel exhaust (DE) gas is a major contributor to combustion derived particulate matter air pollution. In several human experimental studies using a well-validated exposure chamber setup DE has been linked to acute vascular dysfunction and increased thrombus formation. This serves as a plausible mechanistic link between the previously described association between particulate matter air pollution and increased cardiovascular morbidity and mortality.
