No Escape From Diesel Exhaust

By Clean Air Task Force
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. Legions of published, peer-reviewed studies have documented the increased exposure and resultant health risk from particles in and around nearby roadways. When during our day are we exposed to these particles? According to the California Air Resources Board, although we spend only about six percent of our day commuting to and from work, it is during that time when we receive over half of our exposure. Using comparable instruments and research techniques as those employed by health researchers at major universities, Clean Air Task Force (CATF) investigated the exposure to diesel particles during typical commutes in four cities: Austin, Texas, Boston, Massachusetts, New York City, and Columbus, Ohio. In addition, CATF tested the air quality benefits due to emission control retrofits of transit buses in Boston and transit buses and garbage trucks in New York City. 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.

DFW Regional Concerned Citizens attempts to examine issues from all directions. When a story says "By Faith Chatham" it contains my viewpoint. When it is by others, but posted by Faith Chatham, it is from someone else's viewpoint. When I discover contents which is on topic for this site, I frequently link to other sites.
