Mesothelioma - Exposure

Mesothelioma-Exposure Asbestos in ancient times was known, but it was not mined and widely used commercially until the end 1800s. Its use greatly increased during World War II. Since early 1940's, millions of American workers have been exposed to asbestos dust. Initially, the risks associated with exposure to asbestos are not publicly known. However, increased risk of developing mesothelioma was later found among shipyard workers, people who work in asbestos mines and mills, producers of asbestos products, workers in the heating and construction industries, retailers and others. Today, the U.S. Occupational Safety and Health Administration (OSHA) sets limits for acceptable levels of asbestos in the workplace, and created guidelines for the design and management respirators, protective clothing, exposure monitoring, hygiene facilities and practices, warning signs, labeling, recordkeeping, and medical research. In contrast, the British Government Health and Safety Executive (HSE) states that any official threshold for mesothelioma to be at a very low level and it was agreed that greater and if there is no such threshold exists, it can not currently be quantified. For practical purposes, therefore, HSE does not assume that any such threshold exists. People who work with asbestos wear personal protective equipment to lower the risk of exposure. Recent data show that mineral called erionite has been known to cause genetically pre-dispositioned individuals to have malignant mesothelioma rates much higher than those not pre-dispositioned genetically. A study in Cappadocia, Turkey showed that the 3 places in Turkey have death rates of 51% attributed to erionite related mesothelioma
