Asbestos is a naturally occurring mineral that was commonly used in building materials due to its insulating and fire-resistant properties. However, asbestos fibers are fine and easily inhaled into the lungs, leading to a number of serious health conditions. Asbestos exposure has been linked to lung cancer, mesothelioma, and asbestosis, among others.

As a result, the use of asbestos in building materials was banned in the UK in 1999. However, many older buildings still contain asbestos, and proper disposal of this hazardous substance is essential to protect human health and the environment.
