The Dangers of Exposure to AsbestosBefore it was banned asbestos was used in a myriad of commercial products. Research has shown that exposure to asbestos can cause cancer and other health problems.It is impossible to determine if a product has asbestos just by looking at it and you are unable to taste or smell it. Asbestos is only detectable when the material containing it is broken or drilled.ChrysotileAt its height, chrysotile was responsible for 99percent of the asbestos produced. It was widely used in industries which included construction, fireproofing, and insulation. In the event that workers were exposed to this harmful material, they may develop mesothelioma or other asbestos related diseases. Fortunately, the use this harmful mineral has diminished significantly since awareness of mesothelioma began to grow in the 1960's. It is still found in a variety of products we use in the present.Chrysotile can be safely used when a thorough safety and handling plan is put into place. Workers handling chrysotile are not exposed to an undue amount of risk at current limit of exposure. Inhaling airborne fibres is strongly linked to lung fibrosis and lung cancer. This has been proven for intensity (dose) as well as the duration of exposure.In one study mortality rates were compared between a facility that primarily used chlorosotile to make friction materials and the national death rate. It was concluded that for the 40 years of processing asbestos chrysotile at low levels of exposure there was no signifi cant excess mortality in this factory.In contrast to other forms of asbestos, chrysotile fibres tend to be smaller. They can enter the lungs, and enter the bloodstream. They are more likely to cause health issues than longer fibres.It is extremely 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 chrysotile's risk is lower to cause disease than amphibole asbestos, such as crocidolite and amosite. Amphibole types like these are the main cause of mesothelioma and other asbestos-related diseases. When the cement and chrysotile are combined and cured, a tough and flexible product is created that can withstand extreme environmental hazards and weather conditions. It is also simple to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed.AmositeAsbestos is a grouping of fibrous silicates that are found in a variety of rock formations. It is classified into six groups: amphibole (serpentine) and the tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.Asbestos minerals comprise thin, long fibers that vary in length from fine to broad. They can be curled or straight. waterbury asbestos attorney are present in nature as individual fibrils, or as bundles that have splaying ends, referred to as a fibril matrix. Asbestos minerals are also found as a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite that are widely used in consumer products, such as baby powder cosmetics, face powder, and baby powder.Asbestos was extensively used in the early two-thirds of the 20th century for construction of ships insulation, fireproofing and various other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, but some workers also were exposed to asbestos-bearing rock fragments and contaminated vermiculite. Exposures varied by the industry, time frame and geographical location.The majority of asbestos-related exposures in the workplace were caused by inhalation, however some workers were also exposed through contact with skin or through eating contaminated food. Asbestos can be found in the environment due to natural weathering of mined ores and the degradation of contaminated products like insulation, car brakes, clutches, and floor and ceiling tiles.There is emerging evidence that amphibole fibers that are not commercially available could also be carcinogenic. These fibres are not tightly weaved like the fibrils that are found in serpentine and amphibole, they are loose elastic, flexible, and needle-like. These fibers can be found in mountain sandstones, cliffs and sandstones from a variety of nations.Asbestos gets into the environment primarily in the form of airborne particles, however it also leaches into soil and water. This can be caused by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of ground and surface water is largely associated with natural weathering. However, it has also been caused by anthropogenic activities such as milling and mining demolition and dispersal asbestos-containing materials and the disposal of contaminated soils for disposal in landfills (ATSDR 2001). Airborne asbestos fibres are the main cause of illness among people who are exposed to it during their work.CrocidoliteExposure to asbestos through inhalation is the most frequent way people are exposed to the harmful fibres. They can then be inhaled and cause serious health issues. Mesothelioma and asbestosis as well as other illnesses are caused by asbestos fibres. Exposure to fibres can occur in different ways too like contact with contaminated clothing or construction materials. The dangers of this kind of exposure are more pronounced when crocidolite, the asbestos in the blue form is involved. Crocidolite is a smaller, more fragile fibers that are easier to breathe and can be lodged deeper into lung tissue. It has been associated with more mesothelioma cancer cases than other asbestos types.The main types are chrysotile, amosite and chrysotile. Chrysotile and amosite are the most frequently used types of asbestos. They comprise 95 percent of all commercial asbestos that is used. The other four types haven't been as popularly used but they can be found in older buildings. They are not as dangerous as amosite or chrysotile but still be a danger when mixed with other minerals, or when mined near other mineral deposits, such as vermiculite and talc.Numerous studies have demonstrated an association between stomach cancer and asbestos exposure. However the evidence is not conclusive. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% 95% confidence interval: 0.7-3.6) for all asbestos-related workers as well as an SMR of 1.24 (95 percent C.I. 0.76-2.5) for workers in chrysotile mines and mills.The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All kinds of asbestos may cause mesothelioma and other health problems, but the risks are different based on how much exposure people are exposed to, the kind of asbestos involved, the duration of their exposure and the way in the way it is inhaled or consumed. IARC has stated that the best choice for individuals is to stay clear of all types of asbestos. However, if people have been exposed to asbestos in the past and are suffering from a disease such as mesothelioma, or other respiratory illnesses, they should seek guidance from their doctor or NHS 111.AmphiboleAmphiboles are groups of minerals that may create prism-like or needle-like crystals. They are a type of inosilicate mineral that is composed of double chains of SiO4 molecules. They usually possess a monoclinic crystal system however, some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are made up of (Si,Al)O4 Tetrahedrons, which are connected in rings of six. The tetrahedrons are separated by strips of octahedral sites.Amphiboles are present in metamorphic and igneous rock. They are typically dark-colored and are hard. They are sometimes difficult to distinguish from pyroxenes since they share similar hardness and colors. They also have a comparable Cleavage. However, their chemistry allows for the use of a variety of compositions. The chemical compositions and crystal structures of the different minerals in amphibole can be used to identify them.Amphibole asbestos is comprised of chrysotile as well as the five asbestos types amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. The most widely used form of asbestos is chrysotile. Each variety has distinct characteristics. The most dangerous form of asbestos, crocidolite is composed of sharp fibers that are simple to inhale into the lungs. Anthophyllite ranges from brown to yellowish in color and is composed of magnesium and iron. The variety was used previously in cement-based products and insulation materials.Amphibole minerals are challenging to analyze because they have an intricate chemical structure and numerous substitutions. A detailed analysis of the composition of amphibole mineral requires specialized techniques. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. These methods are only able to provide approximate identifications. For instance, these methods can't distinguish between magnesio hastingsite and magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro-hornblende or pargasite.
