The Dangers of Exposure to Asbestos Asbestos was a component in thousands of commercial products prior to when it was banned. Research has shown that exposure to asbestos can cause cancer as well as other health issues. You cannot tell by just looking at something if it is made up of asbestos. Neither can you taste or smell it. Asbestos is only detectable when the material containing it is broken or drilled. Chrysotile At the height of its use, chrysotile made up 99% of asbestos production. It was employed in many industries including construction insulation, fireproofing, and construction. If workers were exposed to this harmful material, they could develop mesothelioma or other asbestos related diseases. Since the 1960s, when mesothelioma became a major concern the use of asbestos has declined significantly. It is still present in a variety of products we use in the present. Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. It has been determined that at the current controlled exposure levels, there isn't an danger to the people who handle the substance. Lung fibrosis, lung cancer and mesothelioma have all been found to be strongly associated with breathing in airborne respirable fibres. This has been proven to be true for both the intensity (dose) and time span of exposure. In one study mortality rates were compared between a manufacturing facility that used a large proportion of chrysotile in the manufacture of friction materials and national death rates. It was discovered that, over the course of 40 years, processing chrysotile asbestos at low levels of exposure there was no signifi cant extra mortality in the factory. Chrysotile fibres are typically shorter than other forms of asbestos. They are able to penetrate the lungs, and then pass through the bloodstream. This makes them more prone to causing health consequences than longer fibres. When chrysotile gets mixed with cement, it is very difficult for the fibres to be airborne and cause health hazards. Fibre cement products are extensively used all over the world, especially in buildings like hospitals and schools. Research has revealed that chrysotile is less likely to cause illness than amphibole asbestos like amosite and crocidolite. Amphibole asbestos types have been the primary cause of mesothelioma and other asbestos-related diseases. When the cement and chrysotile are combined, a durable, flexible product is created that is able to withstand extreme environmental hazards and weather conditions. It is also easy to clean after use. Professionals can safely get rid of asbestos fibres after they have been removed. Amosite Asbestos is a category of fibrous silicate minerals which are found naturally in a variety of types of rock formations. It is composed of six general groups: serpentine, amphibole anthophyllite, tremolite and crocidolite (IARC, 1973). Asbestos minerals consist of thin, long fibres that range in length from very thin to broad and straight to curled. These fibres can be found in nature in bundles, or as individual fibrils. Asbestos is also found in a powder form (talc) or mixed with other minerals in order to create talcum powder or vermiculite. They are used extensively as consumer products, including baby powder, cosmetics and face powder. Asbestos was used extensively in the first two thirds of the 20th century to construct shipbuilding insulation, fireproofing, insulation and various other construction materials. Most occupational exposures were asbestos fibres borne by air, but certain workers were exposed to toxic talc or vermiculite, and to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied according to industry, time period, and geographic location. Exposure to asbestos in the workplace is mainly because of inhalation. However there are workers who have been exposed via skin contact or through eating foods contaminated with asbestos. Asbestos can only be found in the environment due to natural weathering and degradation of contaminated products, such as ceiling and floor tiles cars, brakes and clutches, and insulation. It is becoming evident that non-commercial amphibole fibers can also be carcinogenic. These are fibres don't form the tightly woven fibrils of the amphibole and serpentine minerals but instead are loose, flexible and needle-like. They can be found in the cliffs, mountains and sandstones from a variety of nations. Asbestos may enter the environment in a variety of ways, including through airborne particles. It is also able to leach into water or soil. This can be triggered by both natural (weathering of asbestos-bearing rocks) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination in ground and surface waters is primarily due to natural weathering. However, it has also been caused by human activity, for instance through milling and mining of asbestos-containing materials demolition and dispersal and the disposal of contaminated waste in landfills (ATSDR 2001). The inhalation of asbestos fibres remains the main cause of illness for people exposed to asbestos at work. green bay asbestos attorneys to asbestos through inhalation is the most common way people are exposed to dangerous fibres, which can then get into the lungs and cause serious health issues. Mesothelioma and asbestosis as well as other illnesses can be caused by asbestos fibres. Exposure to asbestos fibers can also take place in other ways, such as contact with contaminated clothes or building materials. The dangers of this kind of exposure are more pronounced when crocidolite (the blue form of asbestos is involved. Crocidolite fibers are thinner and more fragile and therefore easier to breathe in. They can also lodge deeper into lung tissue. It has been associated with more mesothelioma cancer cases than other asbestos types. The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. Chrysotile and amosite are among the most commonly used types of asbestos. They comprise 95% of the asbestos used in commercial construction. The other four asbestos types aren't as common, but may still be present in older structures. They are less dangerous than chrysotile and amosite, but they could pose a threat when combined with other asbestos minerals or mined in close proximity to other mineral deposits, such as vermiculite or talc. Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. The evidence isn't unanimous. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, whereas others report an SMR of 1,24 (95% confidence interval: 0.76-2.5), for workers in chrysotile mills and mines. The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All forms of asbestos could cause mesothelioma as well as other health issues, although the risk is dependent on the amount of exposure people are exposed to, the kind of asbestos involved as well as the duration of exposure and the manner in the way that it is breathed in or consumed. The IARC has recommended that avoiding all forms of asbestos is the best option, as this is the safest option for individuals. If you have been exposed in the past to asbestos and suffer from a respiratory illness or mesothelioma, you should seek advice from your physician or NHS111. Amphibole Amphibole belongs to a group of minerals that form long prisms or needlelike crystals. They are a type of silicate mineral made up of double chains of SiO4 molecules. They usually have a monoclinic crystal structure, although 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 that are linked in rings of six. Tetrahedrons can be separated by octahedral strips. Amphiboles can be found in both igneous and metamorphic rock. They are usually dark and hard. Due to their similarity of hardness and color, they can be difficult for some people to distinguish from pyroxenes. They also share a corresponding cleavage pattern. However, their chemistry allows for the use of a variety of compositions. The various mineral groups in amphibole can be identified by their chemical compositions as well as crystal structures. Amphibole asbestos consists of chrysotile, and the five types of asbestos: amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. While the most popular asbestos type is chrysotile, each variety has distinct characteristics. Crocidolite is considered to be the most hazardous asbestos type. It is composed of sharp fibers which are easily inhaled into the lung. Anthophyllite ranges from brown to yellowish in color and is composed of iron and magnesium. This variety was once used in cement and insulation materials. Amphiboles are a challenge to analyze due to their complex chemical structure and the numerous substitutions. Therefore, a thorough analysis of their composition requires special techniques. The most widely used methods of identifying amphiboles include EDS, WDS, and XRD. However, these methods can only give approximate identifications. These methods, for instance, cannot distinguish between magnesio hastingsite and magnesio hastingsite. These techniques also don't distinguish between ferro-hornblende and pargasite.
