Asbestos in Bulk Dust

If a substance contains 1% or more asbestos, it is considered to be an "asbestos-containing material." EPA is using the 1% definition in evaluating dust samples from in and around ground zero and other areas potentially impacted by the World Trade Center collapse. The majority of areas in which EPA has found levels of asbestos in dust above 1% are in the vicinity of the World Trade Center work zone. Daily summaries of this data and how it compares to the level of concern for public health are also available.

The presence of asbestos in dust is not necessarily a significant health hazard. The dust must become airborne and be inhaled for it to cause health problems. Measurements of asbestos in the air are more accurate indicators of the potential for exposure. If dust or debris from the World Trade Center site has entered homes, schools or businesses, it should be cleaned thoroughly and properly following the recommendations of the New York City Department of Health.
