Which of the following is true about asbestos?

A) There are several types of asbestos, but they represent the same mineral.
B) Different types of asbestos have the same health risks.
C) Each type of asbestos has long, straight fibers.
D) Asbestos represents different minerals with different health risks.

Asbestos refers to a group of six naturally occurring fibrous minerals that are composed of thin, needle-like fibers. These minerals are divided into two main categories: serpentine (which includes chrysotile, the most common type) and amphibole asbestos. Each type of asbestos can pose health risks when inhaled, but the level of risk can vary depending on the type of asbestos and the duration and intensity of exposure. Some types of asbestos fibers are more easily inhaled and can penetrate deeper into the lungs, potentially causing more severe health problems, such as mesothelioma, lung cancer, and asbestosis. Therefore, asbestos represents different minerals with varying health risks, not a single mineral with uniform characteristics and dangers.
