Every day, Americans are needlessly sickened from exposure to air pollution in the form of fine particles. Overall, health researchers estimate that fine particles, such as those found in diesel exhaust, shorten the lives of 70,000 Americans each year. Many more suffer the effects of particle-related respiratory and cardiovascular disease.
CATF’s investigation demonstrated that whether you commute by car, bus, ferry, train, or on foot, you may be exposed to high levels of diesel particles. Specifically, CATF documented diesel particle levels four to eight times higher inside commuter cars, buses, and trains than in the ambient outdoor air in those cities.
