1. Asbestos
Asbestos is a naturally occurring mineral that was once used in construction materials, insulation, and even clothing. Exposure to asbestos fibers can lead to severe lung diseases, including asbestosis, mesothelioma, and lung cancer. The danger lies in inhaling microscopic fibers, which can remain in the lungs for decades before causing harm.
It’s crucial to avoid any direct contact with asbestos or environments where it might be disturbed.
