The Dangers of Exposure to Asbestos Before it was banned, asbestos was used in thousands commercial products. Research shows that exposure to asbestos can cause cancer as well as other health issues. It is impossible to determine if a product has asbestos just simply by looking at it and you are unable to smell or taste it. It is only visible when the asbestos-containing materials are drilled, chipped or broken. Chrysotile At its peak, chrysotile made up for 95% of the asbestos made. It was utilized in a variety of industries including construction insulation, fireproofing and insulation. In the event that workers were exposed to the toxic material, they could contract mesothelioma as well as other asbestos related diseases. Fortunately, the use of this dangerous mineral has decreased drastically since mesothelioma awareness started to grow in the 1960's. However, traces of it can still be found in many of the products we use in the present. Chrysotile is safe to use in the event that you have a complete safety and handling plan in place. Personnel handling chrysotile aren't exposed to a significant amount of risk at the present controlled exposure levels. Lung cancer, lung fibrosis and mesothelioma have been strongly linked to breathing airborne respirable fibres. This has been confirmed for both the intensity (dose) and time span of exposure. One study that examined a factory that used almost exclusively chrysotile in the production of friction materials, compared mortality rates at this factory with national death rates. The study revealed that after 40 years of processing at low levels of chrysotile, there was no significant increase in mortality rates in this factory. Chrysotile fibres tend to be shorter than other types of asbestos. They can pass through the lungs and enter the bloodstream. They are therefore more likely to cause health problems than fibres with longer lengths. It is very difficult for chrysotile fibrous to be inhaled or to pose a health risk when mixed with cement. Fibre cement products are extensively utilized in many areas of the world, including schools and hospitals. Research has shown that amphibole asbestos, like amosite or crocidolite is less likely than chrysotile to cause disease. These amphibole types have been the most common cause of mesothelioma as well as other asbestos-related illnesses. When chrysotile mixes with cement, it forms a strong, flexible building product that is able to withstand severe conditions in the weather and other environmental dangers. It is also easy to clean up after use. Asbestos fibres are easily removed by a professional, and then removed. Amosite Asbestos is one of the groups of fibrous silicates found in a variety of rock formations. It is classified into six groups that include amphibole (serpentine), tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals consist of long, thin fibres that range in length from extremely fine to broad and straight to curled. These fibers are found in nature as bundles or individual fibrils. Asbestos is also found in powder form (talc) or combined with other minerals to create talcum powder or vermiculite. These are widely used in consumer products, such as baby powder cosmetics, and even face powder. Asbestos was widely used during the early two-thirds of the 20th century for shipbuilding insulation, fireproofing, insulation and various other construction materials. The majority of occupational exposures involved asbestos fibres borne by air, but some workers were exposed to toxic talc or vermiculite and to pieces of asbestos-bearing rock (ATSDR 2001). Exposures varied from industry industry, era to and also from geographical location. Most of the asbestos exposures at work were due to inhalation. However, some workers were also exposed by skin contact or through eating contaminated food. Asbestos is found in the environment because of natural weathering and degrading of contaminated materials like ceiling and floor tiles automobile brakes and clutches as well as insulation. It is becoming clear that non-commercial amphibole fibres may also be carcinogenic. These are fibres that do not have the tight knit fibrils of the amphibole and serpentine minerals, but instead are flexible, loose and needle-like. These fibres can be found in mountain sandstones, cliffs and sandstones of a variety of countries. Asbestos gets into the environment primarily as airborne particles, but it can also be absorbed into water and soil. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination in ground and surface waters is primarily caused by natural weathering. However it can also be caused by anthropogeny, such as through the mining and milling of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary cause of illness among people exposed to asbestos in their job. Crocidolite Exposure to asbestos through inhalation is the most common way people are exposed harmful fibres, which could be absorbed into the lungs and cause serious health issues. Mesothelioma, asbestosis and other illnesses are caused by asbestos fibres. Exposure to fibres can occur in other ways, too like contact with contaminated clothing, or building materials. The risks of exposure are higher when crocidolite, the asbestos in the blue form, is involved. Crocidolite fibers are thinner and more fragile making them more palatable to breathe in. They can also be lodged deeper inside lung tissue. It has been associated with a higher number of mesothelioma-related cases than any other form of asbestos. The six main types of asbestos are chrysotile amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. The most well-known forms of asbestos are epoxiemite and chrysotile, which together comprise 95% all commercial asbestos used. The other four types of asbestos haven't been as widely utilized, but they may still be present in older buildings. They are not as dangerous as amosite or chrysotile but still be dangerous when mixed with other minerals or when mined close to other mineral deposits like vermiculite and talc. Numerous studies have revealed an association between stomach cancer and asbestos exposure. The evidence isn't conclusive. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, while others have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for those working in chrysotile mines or chrysotile mills. The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All kinds of asbestos can cause mesothelioma and other health issues, however the risks are different based on the amount of exposure that individuals are exposed to, the type of asbestos used, the duration of their exposure and the method by the way it is inhaled or consumed. paterson asbestos attorney has advised that avoid all forms of asbestos is the best option since this is the safest option for those who are exposed. However, if a person has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma or other respiratory diseases and require advice, they should seek out guidance from their GP or NHS 111. Amphibole Amphibole belongs to a group of minerals that form long prisms or needle-like crystals. They are a type of inosilicate mineral composed of double chains of SiO4 molecules. They are a monoclinic system of crystals, but some have an orthorhombic shape. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains contain (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. The tetrahedrons can be separated by strips of octahedral site. Amphiboles can be found in metamorphic and igneous rock. They are usually dark and hard. They can be difficult to differentiate from pyroxenes due to their similar hardness and color. They also share a corresponding Cleavage. Their chemistry allows a wide range of compositions. The chemical compositions and crystal structures of the different mineral groups in amphibole could be used to identify them. Amphibole asbestos comprises chrysotile and the five asbestos types: amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. Each type of asbestos has its own distinct properties. Crocidolite is the most hazardous asbestos kind. It has sharp fibers which are easily breathed into the lung. Anthophyllite has a brownish to yellowish hue and is made mostly of iron and magnesium. This variety was used to make cement and insulation materials. Amphibole minerals are difficult to study because of their a complicated chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires special techniques. The most widely used methods to identify amphiboles are EDS, WDS, and XRD. These methods are only able to provide approximate identifications. These techniques, for example, cannot distinguish between magnesio hastingsite and magnesio hastingsite. In addition, these techniques can not distinguish between ferro-hornblende as well as pargasite.
