Asbestos or asbestus (ass-BES-təə s, az-, -⁠⁠ toss) is a group of normally taking place, coarse silicate minerals, made use of for thousands of years to develop versatile objects that withstand fire, such as fire resistant fabrics, yet are now known to be harmful and cancer causing. There are six kinds, every one of which are made up of long and thin fibrous crystals, each fibre (particulate with length significantly higher than width) being composed of several microscopic "fibrils" that can be launched into the atmosphere by abrasion and other procedures. Breathing of asbestos fibres can bring about numerous harmful lung conditions, consisting of mesothelioma cancer, asbestosis, and lung cancer. As an outcome of these health and wellness effects, asbestos is thought about a serious health and wellness risk. Archaeological researches have actually located evidence of asbestos being made use of as far back as the Rock Age to reinforce ceramic pots, yet massive mining started at the end of the 19th century when producers and building contractors began utilizing asbestos for its preferable physical properties. Asbestos is an exceptional thermal and electric insulator, and is highly fire-resistant, so for much of the 20th century, it was extremely generally made use of all over the world as a structure material (especially for its fire-retardant residential or commercial properties), up until its damaging results on human wellness were more commonly acknowledged and recognized in the 1970s.

The latency duration (from exposure till the diagnosis of adverse wellness impacts) is usually twenty years. One of the most usual diseases associated with chronic asbestos direct exposure are asbestosis (scarring of the lungs because of asbestos breathing) and mesothelioma cancer (a kind of cancer cells). Lots of establishing countries still support making use of asbestos as a structure material, and mining of asbestos is continuous, with the top producer, Russia, having an approximated manufacturing of 790,000 tonnes in 2020.
