Can vermiculite be tested for asbestos?
In a breakthrough study, the U.S. Geological Survey (USGS) found a way to test for trace levels of asbestos in vermiculite insulation on-site, which marks a promising development in public health.
Can you test dust for asbestos?

How do you sample vermiculite for asbestos?
Enter the attic, being careful not to disturb the vermiculite.

Asbestos fibers in vermiculite are too small to be seen by the naked eye. Only a trained technician using a microscope can see asbestos fibers.
What percentage of vermiculite has asbestos?
Vermiculite is a naturally occurring mineral that is perfectly safe when pure. Unfortunately, an estimated 75 percent of it came from Libby, Montana, where it usually was contaminated with toxic amphibole asbestos. Exposure to asbestos is the main cause of mesothelioma, an aggressive and deadly cancer.
What happens if you breathe in asbestos once?
It is possible to develop an illness such as asbestosis, mesothelioma, pleural effusions or lung cancer after a one-time exposure to asbestos if the exposure was significant enough to lead to asbestos particles lodging in the body’s tissues.

Asbestosis signs and symptoms may include:
- Shortness of breath.
- A persistent, dry cough.
- Chest tightness or pain.
- Dry and crackling sounds in your lungs when you inhale.
- Fingertips and toes that appear wider and rounder than usual (clubbing)

If you breathe asbestos fibers, you may increase the risk of several serious diseases, including asbestosis, mesothelioma and lung cancer. Asbestos exposure may increase your risk for cancers of the digestive system, including colon cancer.
Can a single exposure to asbestos cause mesothelioma?
One-time exposure to asbestos can cause diseases, including mesothelioma cancer. Researchers have found repeated exposure to asbestos increases the risk of developing asbestos-related cancers. The risk to individuals who have a one-time exposure to asbestos is generally lower compared to long-term or repeated exposure.
