New concentrations reported for metals and volatile organic compounds in New Orleans continue to be below health-based screening levels, according to the EPA.

These monitoring results also include the first results of outdoor sampling for asbestos in New Orleans. Asbestos was not detected in the air samples collected Oct. 9 -- 23 at nine monitoring locations. The EPA does not normally do ambient air sampling for asbestos, but will continue sampling for this substance throughout the demolition and debris disposal process in the hurricane-affected areas, according to the agency.

The air quality data is available at www.epa.gov/katrina/testresults/air/index.html.
