Asbestos is a naturally occurring fibrous mineral that was once widely used in a variety of building materials, including paint. When asbestos is mixed with paint, it can create a durable, fire-resistant coating. However, asbestos is also a known carcinogen, and its use in paint has been banned in many countries.
Asbestos fibers are very small and can be easily inhaled. When inhaled, these fibers can lodge in the lungs and cause serious health problems, including lung cancer, mesothelioma, and asbestosis. The risk of developing these diseases is highest for people who have been exposed to high levels of asbestos for a long period of time.
