The Dangers of Exposure to Asbestos Asbestos was found in thousands of commercial products prior to when it was banned. According to studies, exposure to asbestos can cause cancer and many other health problems. It is impossible to tell just by looking at something if it is made up of asbestos. It is also impossible to smell or taste it. Asbestos can only be detected when the material containing it is broken, drilled, or chipped. Chrysotile At the height of its use, chrysotile made the majority of the asbestos produced. It was used in many industries, including construction, insulation, and fireproofing. If workers were exposed for long periods to this toxic material, they could develop mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma began to become a concern the use of asbestos has been drastically reduced. It is still found in a variety of products we use today. Chrysotile can be used in a safe manner in the event that a thorough safety and handling plan is put in place. It has been discovered that at the present exposure levels, there is no unneeded risk to the people who handle the substance. Inhaling airborne fibres has been strongly associated with lung cancer and lung fibrosis. This has been confirmed for both intensity (dose) and duration of exposure. In one study, mortality rates were compared between a facility which used almost exclusively chlorosotile to make friction materials and national death rates. The study concluded that, after 40 years of converting low levels of chrysotile there was no significant rise in mortality at this factory. Chrysotile fibers are generally shorter than other types of asbestos. They can pass through the lungs and then enter the bloodstream. They are more likely to cause health problems than fibres that are longer. When chrysotile gets mixed with cement, it is extremely difficult for the fibres to air-borne and pose health risks. Fibre cement products are widely used in a variety of locations around the world including hospitals and schools. Research has revealed that chrysotile's risk is lower to cause disease than amphibole asbestos, like amosite and crocidolite. Amphibole types like these are the main source of mesothelioma as well as other asbestos-related diseases. When chrysotile is mixed in with cement, it forms a strong, flexible construction product that can withstand harsh weather conditions and other environmental hazards. It is also simple to clean after use. Professionals can safely remove asbestos fibres once they have been removed. Amosite Asbestos refers to a set of silicate mineral fibrous that naturally occur in certain kinds of rock formations. It is classified into six groups: amphibole (serpentine) and tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are composed of thin, long fibres that range in length, ranging from very fine to wide and straight to curled. They are found in nature as individual fibrils, or as bundles that have splaying ends, referred to as fibril matrix. Asbestos minerals can be found in the form of a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite which are widely used in consumer products, such as baby powder cosmetics, face powder and other. The greatest asbestos use was during the first two-thirds of twentieth century in the period when it was employed in insulation, shipbuilding, fireproofing and other construction materials. The majority of asbestos-related exposures in the workplace were in the air, but some workers were also exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied from industry industry, era to era and even geographical location. palm bay asbestos attorney to asbestos in the workplace is mainly because of inhalation. However there are workers who have been exposed through skin contact or through eating foods contaminated with asbestos. Asbestos is found in the natural environment due to natural weathering and degradation of contaminated products like ceiling and floor tiles cars, brakes and clutches, and insulation. There is evidence to suggest that amphibole fibres from non-commercial sources could also be carcinogenic. These are the fibres that are not the tightly woven fibrils of the amphibole and serpentine minerals, but instead are loose, flexible and needle-like. These fibers are found in the cliffs, mountains and sandstones of many countries. Asbestos gets into the environment primarily as airborne particles, but it can also be absorbed into water and soil. This is caused by both natural (weathering of asbestos-bearing rock) 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 can also be caused by human activity, for instance through the mining and milling of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping material in landfills (ATSDR 2001). The inhalation of asbestos fibres is the most common reason for illness among those exposed to it occupationally. Crocidolite Inhalation exposure to asbestos is the most frequent way people are exposed to harmful fibres, which could then be inhaled and cause serious health issues. Mesothelioma, asbestosis and other illnesses are all caused by asbestos fibres. Exposure to asbestos fibers can occur in different ways, like contact with contaminated clothes or building materials. The dangers of exposure are more pronounced when crocidolite, a asbestos' blue form, is involved. Crocidolite has smaller, more fragile fibers that are more easy to inhale and can lodge deeper into lung tissue. It has been linked to a greater number of mesothelioma related cases than any other form of asbestos. The six main types of asbestos are chrysotile amosite, epoxiemite, tremolite anthophyllite and actinolite. The most commonly used asbestos types are epoxiemite as well as chrysotile which together comprise 95% all commercial asbestos used. The other four forms haven't been as extensively used, but they may still be present in older buildings. They are not as dangerous as amosite or chrysotile however they could still be a danger when combined with other minerals or when mined close to other mineral deposits, such as vermiculite and talc. A number of studies have demonstrated an connection between exposure to asbestos and stomach cancer. However, the evidence is contradictory. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all workers exposed to asbestos while other studies have reported an SMR of 1.24 (95% CI: 0.76-2.5) for those who work in chrysotile mines and mills. The International Agency for Research on Cancer (IARC) has classed all asbestos types as carcinogenic. All types of asbestos can cause mesothelioma or other health issues, but the risks vary according to the amount of exposure individuals are exposed to, the type of asbestos used as well as the length of their exposure and the manner in which it is breathed in or ingested. The IARC has advised that avoiding all forms of asbestos is the best option as it is the safest option for people. If you have been exposed to asbestos and are suffering from respiratory issues or mesothelioma condition, then you should seek advice from your physician or NHS111. Amphibole Amphibole is a group of minerals that form long prisms or needle-like crystals. They are an inosilicate minerals made of double chains of SiO4 molecules. They usually possess a monoclinic crystal system however some may have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are composed of (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. The tetrahedrons are separated by strips of octahedral sites. Amphibole minerals are prevalent in metamorphic and igneous rocks. They are typically dark and hard. Due to their similarity in strength and colour, they can be difficult for some people to distinguish from pyroxenes. They also have a comparable Cleavage. Their chemistry can allow for a variety 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 types of asbestos: amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. Each variety of asbestos has its own unique properties. The most harmful type of asbestos, crocidolite, is composed of sharp fibers that are simple to breathe into the lung. Anthophyllite is yellowish to brown in color and is made up of magnesium and iron. This kind of material was used to create cement and insulation materials. Amphibole minerals are challenging to study because of their an intricate chemical structure and a variety of substitutions. Therefore, a thorough analysis of their composition requires specialized techniques. The most commonly used methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods only provide approximate identifications. For example, these techniques cannot differentiate between magnesio-hastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro hornblende and pargasite.
