Subway Risks

The New York Times has an interesting article about airborne metal particles found in underground rail stations, and their potential links to respiratory problems. The article also touches on noise concerns and the persistent fear of crime that many subway riders experience. From the article:

While violent crime in the subway has plummeted over the past decade,
riders continue to have fears that are not rationally grounded, Dr. Gershon found. She cited, for example, a 1992 survey that found that 77 percent of subway riders were afraid of being pushed onto the tracks, and 80 percent said they took action to prevent this from happening, even though such incidents are extremely rare.
