ATSDR MEDIA ANNOUNCEMENT

Workers at Nine Former Vermiculite Processing Plants
Were Exposed to Asbestos

For Immediate Release: September 22, 2005

ATLANTA - Workers that processed vermiculite from a mine in Libby, Montana at nine former plants located throughout the United States were exposed to asbestos and are at increased risk for developing asbestos related health problems, the Agency for Toxic Substances and Disease Registry (ATSDR) reports in public health consultations released today. The plants that processed Libby vermiculite are located in Dallas, TX; Ellwood City, PA; Honolulu, HI; Marysville, OH; New Orleans, LA; Newark, CA; New Castle, PA; Portland, OR; and Wilder, KY.

Today's releases bring to 21 the number of public health consultations completed in a series of 28 evaluations being conducted at sites across the United States that received and processed vermiculite mined in Libby, MT. The vermiculite from Libby contained asbestos. While exposure to asbestos does not mean a person will develop health problems, ATSDR has linked some exposures to Libby vermiculite to respiratory illnesses. The remaining reports will be released by the end of 2005.

The major findings for the sites are consistent with many of those found at the other sites evaluated, mainly:

ATSDR recommends that former workers and for many of the sites, household members who lived with them, take specific steps to protect their health and improve quality of life:

Residents could have been exposed to asbestos if they handled or played in waste rock, a by-product of vermiculite exfoliation. At some vermiculite plants, workers or people in the community may have brought waste rock from the plant to their homes. This waste rock was used in many ways, for example in gardens and as fill or driveway surfacing material.

When processing vermiculite, the plants might have released dust and asbestos fibers into the air. ATSDR cannot determine the extent of exposure to former residents who lived near the plant.

Most current residents living around the former plants are not being exposed to asbestos from the sites. All the plants stopped processing asbestos-contaminated vermiculite years ago. It is possible that workers or people in the community may have brought home asbestos-contaminated waste rock home to use in their gardens and other areas. When waste rock that is uncovered and open to the air is stirred up, asbestos fibers may be released into the air.

The ATSDR public health consultations for the 21 sites evaluated to date are available on-line at http://www.atsdr.cdc.gov/naer/natlmap.html.

ATSDR, a public health agency of the U.S. Department of Health and Human Services, evaluates the human health effects from exposure to hazardous substances.
