The Dangers of Exposure to Asbestos Before it was banned, asbestos was still used in a variety of commercial products. Research shows that exposure to asbestos can cause cancer and other health problems. It is not possible to tell by simply looking at something if it is made of asbestos. You cannot smell or taste it. Asbestos can only be detected when the substances that contain it are broken, drilled, or chipped. Chrysotile At its height, chrysotile provided for 99% of the asbestos made. It was widely used in industries, including construction insulation, fireproofing, and insulation. If workers are exposed to asbestos, they can develop mesothelioma as well as other asbestos-related illnesses. Thankfully, the use of this dangerous mineral has decreased significantly since mesothelioma awareness began to grow in the 1960's. However, trace amounts of it can still be found in the products we use today. Chrysotile is safe to use with a well-thought-out safety and handling plan is put into place. People who handle chrysotile do not exposed to a significant amount of risk at current safe exposure levels. Inhaling airborne fibres has been strongly associated with lung cancer and lung fibrosis. This has been confirmed both in terms of intensity (dose) as well as the duration of exposure. In one study, mortality rates were compared among a factory that primarily used Chrysotile in the production of friction materials and the national death rate. It was concluded that for 40 years of processing asbestos chrysotile in low levels of exposure There was no significant additional mortality in this factory. Contrary to other types of asbestos, chrysotile fibers tend to be shorter. They are able to enter the lungs and enter the bloodstream. This makes them much more likely to cause health effects than fibrils with a longer length. It is very difficult for chrysotile fibers to be in the air or pose a health risk when mixed with cement. Fibre cement products are used in various parts of the world, including schools and hospitals. Research has proven that amphibole asbestos, such as crocidolite or amosite is less likely than chrysotile to cause diseases. These amphibole varieties are the main source of mesothelioma as well as other asbestos-related diseases. When chrysotile mixes with cement, it forms a tough, flexible building product that can withstand the most extreme conditions in the weather and other environmental dangers. It is also very easy to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed. Amosite Asbestos is a class of fibrous silicates that are found in certain types rock formations. It is comprised of six general groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC, 1973). Asbestos minerals are made up of long, thin fibers that range in length from fine to broad. They can be curled or straight. They are found in nature as individual fibrils or bundles that have splaying ends, referred to as a fibril matrix. Asbestos can also be found in powder form (talc), or combined with other minerals in order to create vermiculite or talcum powder. They are used extensively in consumer products such as baby powder, cosmetics, and face powder. The largest asbestos use was during the first two-thirds of 20th century, when it was used in shipbuilding, insulation, fireproofing and other construction materials. The majority of occupational exposures to asbestos fibres were in the air, but some workers also were exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied from industry industry, era to era and geographic location. Most asbestos exposures at work were due to inhalation. However, some workers were also exposed by skin contact or by eating food contaminated with asbestos. Asbestos is currently only found in the air due to the natural weathering of mined ore and the degradation of contaminated products such as insulation, car brakes and clutches, and floor and ceiling tiles. It is becoming increasingly apparent that non-commercial amphibole fibers could also be carcinogenic. These are the fibres that are not the tightly knit fibrils of the amphibole and serpentine minerals but instead are flexible, loose and needle-like. These fibres can be found in mountains, sandstones, and cliffs of a variety of countries. boca raton asbestos law firm can be found in the environment in the form of airborne particles, however it also leaches into water and soil. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and anthropogenic (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination in surface and ground waters is primarily caused through natural weathering. However it is also caused by humans, such as through mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated dumping material in landfills (ATSDR 2001). Exposure to asbestos-containing airborne fibers is the primary cause of illness among people exposed to asbestos at work. Crocidolite Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can get into the lungs which can cause serious health issues. Mesothelioma and asbestosis as well as other illnesses are all caused by asbestos fibres. Exposure to asbestos fibres can be triggered in other ways, such as contact with contaminated clothes or building materials. This type of exposure is more dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe and can be lodged deeper into lung tissue. It has been linked to a higher number of mesothelioma related cases than any other type of asbestos. The six main types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. The most commonly used asbestos types are chrysotile and epoxiemite, which together comprise 95% all commercial asbestos employed. The other four asbestos types are not as prevalent, but could still be present in older structures. They are less hazardous than chrysotile and amosite, but they could be a risk when combined with other asbestos minerals, or when mined close to other naturally occurring mineral deposits, such as talc or vermiculite. Numerous studies have shown that there is a link between stomach cancer and asbestos exposure. The evidence isn't conclusive. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers, while others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those who work in mines and chrysotile mills. The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All asbestos types can cause mesothelioma, but the risks vary depending on the amount of exposure, what type of asbestos is involved, and how long exposure lasts. The IARC has advised that avoid all forms of asbestos should be the highest priority as it is the best option for those who are exposed. If you have been exposed in the past to asbestos and suffer from a respiratory illness or mesothelioma, then you should talk to your doctor or NHS111. Amphibole Amphiboles comprise a variety of minerals which can form prism-like or needle-like crystals. They are a type of inosilicate minerals made of double chains of SiO4 molecules. They have a monoclinic system of crystals, but some exhibit an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains contain (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. Tetrahedrons can be separated by strips of octahedral sites. Amphibole minerals are found in igneous and metamorphic rocks. They are typically dark and hard. They can be difficult to distinguish from pyroxenes as they share similar hardness and color. They also share a corresponding the cleavage. However, their chemistry allows for an array of compositions. The different mineral groups in amphibole can be identified by their chemical compositions and crystal structures. Amphibole asbestos consists of chrysotile, and the five types of asbestos: amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. While the most popular form of asbestos is chrysotile each type is unique in its own way. Crocidolite is among the most dangerous asbestos kind. It contains sharp fibers that can be easily breathed into the lung. Anthophyllite can range from yellow to brown in color and is composed of iron and magnesium. The variety was used previously in cement and insulation materials. Amphibole minerals can be difficult to analyze due to their a complicated chemical structure and a variety of substitutions. Therefore, a thorough analysis of their composition requires special techniques. EDS, WDS and XRD are the most widely used methods of identifying amphiboles. These methods are only able to provide approximate identifications. For example, these techniques cannot distinguish between magnesiohastingsite and magnesio-hornblende. Moreover, these techniques do not distinguish between ferro-hornblende or pargasite.
