Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
The Atlas Asbestos Mine Superfund Site is located within the Clear Creek Management Area near Fresno County, eighteen miles northwest of Coalinga, California. The mine started operating in 1963, covering 435 acres of a large naturally occurring asbestos deposit.
The mineral asbestos is subject to a wide range of laws and regulations that relate to its production and use, including mining, manufacturing, use and disposal. [1] [2] [3] Injuries attributed to asbestos have resulted in both workers' compensation claims and injury litigation.
The natural rock formations in the area have been shedding asbestos-rich debris into stream valleys for millions of years [17] The average New Idria rock contains 5-15% by volume short fiber asbestos. [17] The 2010 edition of Rand McNally's The Road Atlas labels the area immediately south of New Idria as an "Asbestos Hazard Area".
Asbestos litigation is the longest, most expensive mass tort in U.S. history, involving more than 8,000 defendants and 700,000 claimants. [1] By the early 1990s, "more than half of the 25 largest asbestos manufacturers in the US, including Amatex, Carey-Canada, Celotex, Eagle-Picher, Forty-Eight Insulations, Manville Corporation, National Gypsum, Standard Insulation, Unarco, and UNR Industries ...
The Toxic Substances Control Act (TSCA) is a United States law, passed by the 94th United States Congress in 1976 and administered by the United States Environmental Protection Agency (EPA), that regulates chemicals not regulated by other U.S. federal statutes, [1] including chemicals already in commerce and the introduction of new chemicals.
Those who worked in the production, milling, manufacturing, installation, or removal of asbestos products before the late 1970s are at an increased risk of exposure to asbestos. This includes people who worked in these jobs in the United States and Canada. For example: Asbestos miners; Aeronautical and car mechanics; Boiler operators ...
Higher concentrations of airborne asbestos fibers are reported in urban areas where there is more ACM (asbestos containing materials) and mechanisms of release (vehicles braking and weathering of asbestos cement materials); concentrations in the range of 1–20 ng/m 3 have been reported. Fibers longer than 5μm are rarely found in rural areas.
