EPA whistleblower says US hid 9/11 dust danger

EPA whistleblower says US hid 9/11 dust dangerfrom new york times: A senior scientist at the Environmental Protection Agency has accused the agency of relying on misleading data about the health hazards of World Trade Center dust.

The scientist, who has been sharply critical of the agency in the past, claimed in a letter to members of the New York Congressional delegation this week that test reports in 2002 and 2003 distorted the alkalinity, or pH level, of the dust released when the twin towers collapsed, downplaying its danger.

Some doctors suspect that the highly alkaline nature of the dust contributed to the variety of ailments that recovery workers and residents have complained of since the attack.

Tests of the gray-brown dust conducted by scientists at the United States Geological Survey a few months after the attack found that the dust was highly alkaline, in some instances as caustic or corrosive as drain cleaner, and capable of causing severe irritation and burns.
