We investigated dirty air in Boston and found extremely high levels of pollution in the Tip O'Neill Tunnel. Our test was done in the middle of the day, so you can only assume the levels would be even higher during rush hour.

We tested for ultra-fine particles with a scientist from the Clean Air Task Force. The ultra-fine particles come from diesel exhaust and are currently not regulated by the Environmental Protection Agency. But research has shown they can cause serious health problems like asthma attacks, cardiovascular disease, and even death.

The Turnpike Authority tells us it's concerned about the levels, but claims it can't do anything about them unless the federal government regulates the ultra-fine particles. The scientist recommends driving through the tunnel with your windows up and your air conditioning on the setting that recirculates the air.
