The Dangers of Exposure to Asbestos Before it was banned asbestos was widely used in commercial products. According research, exposure to asbestos can cause cancer as well as other health problems. It is difficult to tell if something is asbestos-containing simply by looking at it and you can't smell or taste it. Asbestos is only detected when the materials that contain it are broken or drilled. Chrysotile At its peak, chrysotile accounted for the majority of the asbestos production. It was employed in many industries which included construction insulation, fireproofing, and construction. If workers were exposed to this toxic material, they could develop mesothelioma, as well as other asbestos-related diseases. Since the 1960s, when mesothelioma began to become a problem asbestos use has been reduced significantly. However, trace amounts of it are still found in common products that we use in the present. Chrysotile can be safely used if a thorough safety and handling plan is put in place. People who handle chrysotile do not at risk of being exposed to a high degree of risk at the present safe exposure levels. Inhaling airborne fibres has been linked with lung cancer and lung fibrosis. This has been confirmed for both intensity (dose) and time span of exposure. In one study mortality rates were compared between a manufacturing facility which used largely chrysotile in the manufacture of friction materials and national death rates. It was found that, for 40 years of processing asbestos chrysotile at low levels of exposure there was no significant increase in mortality in this particular factory. In contrast to other forms of asbestos, chrysotile fibers tend to be shorter. They can pass through the lungs, and then pass through the bloodstream. This makes them much more prone to cause negative effects than fibrils with a longer length. 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 widely used in a variety of locations around the world including hospitals and schools. Research has shown that chrysotile has a lower chance to cause illness than amphibole asbestos, like amosite and crocidolite. These amphibole kinds have been the main cause of mesothelioma and various asbestos-related illnesses. When cement and chrysotile are mixed with cement, a tough product is produced that is able to withstand extreme weather conditions and environmental hazards. It is also easy to clean up after use. Asbestos fibres can be easily removed by a professional and then safely eliminated. Amosite Asbestos refers to a set of silicate minerals with fibrous structure which are found naturally in a variety of types of rock formations. It is comprised of six main groups: amphibole, serpentine anthophyllite, tremolite and crocidolite (IARC 1973). Asbestos minerals are composed of long, thin fibers that range in length from fine to broad. They can also be straight or curled. They are present in nature as individual fibrils or bundles with splaying edges called fibril matrix. Asbestos can also be found in powder form (talc), or mixed with other minerals to create talcum powder or vermiculite. They are extensively used as consumer products, such as baby powder cosmetics and facial powder. The most extensive asbestos use occurred during the first two-thirds of the twentieth century in the period when it was employed in shipbuilding, insulation, fireproofing and other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, however certain workers were also exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied from industry industry, era to and geographic location. Most of the asbestos-related exposures in the workplace were caused by inhalation, however certain workers were exposed via skin contact or through eating contaminated food. Asbestos can be found in the air due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles, car brakes and clutches, as well as insulation. It is becoming apparent that amphibole fibers that are not commercially available could also be carcinogenic. These are fibres do not form the tightly weaved fibrils of amphibole and serpentine minerals but instead are loose, flexible and needle-like. These fibers can be found in the cliffs, mountains and sandstones in a variety of countries. Asbestos can enter the environment in many ways, including through airborne particles. It can also be released into water or soil. This is a result of both natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination of ground and surface water is typically a result of natural weathering, but has also been triggered by anthropogenic activities such as mining and milling demolition and dispersal asbestos-containing materials, and the removal of contaminated soils for disposal in landfills (ATSDR, 2001). Inhalation exposure to asbestos fibers is the primary cause of illness for people exposed to it occupationally. Crocidolite Inhalation exposure is the most common method of exposure to asbestos fibres. The fibres can penetrate the lungs, causing serious health problems. These include asbestosis and mesothelioma. Exposure to fibers can occur in different ways too like contact with contaminated clothing, or building materials. This type of exposure is particularly dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are softer and less brittle which makes them more difficult to breathe in. They can also be lodged deeper in lung tissues. It has been associated with a higher number of mesothelioma-related cases than any other type of asbestos. The six major kinds are chrysotile and amosite. The most well-known asbestos types are epoxiemite and chrysotile, which together comprise the majority of commercial asbestos employed. The other four types haven't been as widely used, but they may still be found in older buildings. They are not as dangerous as amosite or chrysotile, but they can still be a risk when mixed with other minerals, or when mined close to other mineral deposits, such as vermiculite and talc. Numerous studies have shown the connection between stomach cancer and asbestos exposure. However the evidence isn't conclusive. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, and others have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for those who work in chrysotile mills and mines. The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All types of asbestos can cause mesothelioma as well as other health issues, but the risks vary according to the amount of exposure people are exposed to, the kind of asbestos involved and the duration of their exposure and the method by the way that it is breathed in or consumed. IARC has declared that the best option for individuals is to avoid all types of asbestos. However, if people have been exposed to asbestos in the past and suffer from a disease such as mesothelioma or other respiratory diseases and require advice, they should seek out guidance from their doctor or NHS 111. Amphibole Amphiboles are a collection of minerals that may create prism-like or needle-like crystals. They are an inosilicate mineral that is composed of two chains of SiO4 molecules. They usually possess a monoclinic crystal system but some also have 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 by tetrahedron rings made of six. The tetrahedrons are separated each other by strips of octahedral sites. Amphiboles can be found in both igneous and metamorphic rock. They are usually dark and hard. Due to their similarity of hardness and colour, they can be difficult for some to distinguish from pyroxenes. They also share a similar the cleavage pattern. Their chemistry can allow for a range of compositions. The chemical compositions and crystal structure of the various mineral groups in amphibole can be used to determine their composition. Amphibole asbestos consists of chrysotile, and the five types of asbestos amosite anthophyllite (crocidolite) amosite (actinolite) and amosite. Each type of asbestos comes with distinct characteristics. Crocidolite is the most hazardous asbestos type. It contains sharp fibers that can be easily inhaled into the lung. Anthophyllite comes in a brownish-to yellowish hue and is made mostly of iron and magnesium. lakeland asbestos attorney was used to make cement and insulation materials. Amphiboles can be difficult to study due to their complex chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires special methods. EDS, WDS and XRD are the most common methods for identifying amphiboles. However, these methods can only give approximate identifications. For example, these techniques cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques do not differentiate between ferro-hornblende or pargasite.
