Health Risks

Exposure to Actinolite 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 Actinolite Was Found

Actinolite was primarily sourced from:

• Found worldwide as contaminant

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