asbestos

This term refers to a group of naturally occurring silicate minerals prized for their extreme resistance to heat, fire, and electrical conductivity. It is most commonly associated with industrial construction and legacy home insulation from the mid-twentieth century.

Because the mineral fibers are microscopic and hazardous when airborne, the word carries a strong negative connotation of toxicity and danger. In modern usage, it frequently appears in the context of environmental remediation, hazardous waste removal, and occupational health warnings.
