Why Is Asbestos Bad?
why is asbestos bad
Asbestos is considered dangerous because its microscopic fibers, when inhaled, can cause serious and often fatal diseases. The health risks associated with asbestos exposure have led to its banning or strict regulation in many countries worldwide.
Health Risks of Asbestos Exposure
When asbestos-containing materials are disturbed, they release tiny fibers into the air that can be easily inhaled. These fibers are sharp and durable, allowing them to penetrate deep into lung tissue. The body's immune system cannot break down or remove these fibers effectively, leading to chronic inflammation and tissue damage over time.
Diseases Caused by Asbestos
The primary diseases caused by asbestos exposure include asbestosis, lung cancer, and mesothelioma. Asbestosis is a chronic lung condition characterized by scarring of lung tissue, leading to breathing difficulties and reduced lung function. Mesothelioma is a rare and aggressive cancer that affects the lining of the lungs, abdomen, or heart.
One of the most concerning aspects of asbestos-related diseases is their long latency period. Symptoms may not appear for 20-50 years after exposure, meaning many people don't realize they've been affected until decades later. This delayed onset makes early detection and prevention challenging.
There is no safe level of asbestos exposure. Even brief or low-level exposure can potentially lead to health problems, though the risk increases with the duration and intensity of exposure. The fibers accumulate in the body over time, so repeated exposures add to the total burden.
Despite its useful properties, the health risks of asbestos far outweigh any benefits. Modern alternatives exist for most asbestos applications, making continued use unnecessary in most cases. Proper handling and abatement procedures are essential when dealing with existing asbestos materials to prevent fiber release and protect public health.
