Tremolite

About Tremolite Asbestos

Tremolite, commonly called tremolite asbestos, belongs to the amphibole family of asbestos minerals. Straight, sharp fibers characterize this mineral.

Responsible for mesothelioma in talc miners, cosmetic users, and Libby vermiculite workers. Causes disease at lower exposure levels.

Primary Uses

Tremolite was used in various industrial and commercial applications:

• Not commercially mined—found as contaminant

Health Risks

Exposure to Tremolite asbestos can cause:

• Mesothelioma — Aggressive cancer of the lung lining, heart lining, or abdominal lining with a median survival of 12-21 months
• Lung cancer — Risk increases significantly, especially with combined smoking exposure
• Asbestosis — Progressive scarring of lung tissue causing breathing difficulties
• Pleural disease — Thickening, plaques, and effusions in the lung lining

Symptoms may not appear until 20-50 years after initial exposure, making early detection challenging.

Where Tremolite Was Found

Tremolite was primarily sourced from:

• Found worldwide as contaminant in other minerals

Peak usage in the United States occurred during the mid-20th century when contaminated products were common.

Current Regulatory Status

Status: Regulated as asbestos under EPA

Despite regulations, legacy asbestos remains in millions of buildings constructed before 1980. Renovation, demolition, and maintenance activities continue to expose workers and building occupants to asbestos fibers.
