The Dangers of Exposure to Asbestos<br> <br> <br> <br> Before it was banned, asbestos was still used in a variety of commercial products. According to studies, <a href="http://chungho.ktib.co.kr/bbs/board.php?bo_table=free&wr_id=340170">asbestos compensation</a> exposure to asbestos can cause cancer, as well as other health problems.<br> <br> <br> <br> You cannot tell by just looking at a thing if it is made up of asbestos. Also, you cannot smell or taste it. Asbestos can only be identified when materials containing it are broken, drilled, or chipped.<br> <br> <br> <br> Chrysotile<br> <br> <br> <br> At the height of its use, chrysotile made the majority of asbestos production. It was employed in a variety of industries including construction, insulation, and fireproofing. If workers are exposed to asbestos, they can develop mesothelioma as well as other asbestos-related illnesses. Thankfully, the use of this dangerous mineral has decreased drastically since mesothelioma awareness started to increase in the 1960's. It is still present in a variety of products we use today.<br> <br> <br> <br> Chrysotile is safe to use in the event that you have a complete safety and handling plan in place. It has been proven that, at the present controlled exposure levels, there isn't an unneeded risk to the people handling it. Inhaling airborne fibres has been linked with lung fibrosis and lung cancer. This has been confirmed for both intensity (dose) and time span of exposure.<br> <br> <br> <br> One study that examined the operation of a factory that utilized almost all chrysotile as its friction materials compared mortality rates in this factory with national death rates. It was found that for the 40 years of processing asbestos chrysotile at a low level of exposure there was no signifi cant excess mortality in this factory.<br> <br> <br> <br> In contrast to other forms of asbestos, chrysotile fibers tend to be shorter. They are able to enter the lungs, and then pass through the bloodstream. This makes them much more prone to causing health effects than fibres with longer lengths.<br> <br> <br> <br> When chrysotile is mixed into cement, it is extremely difficult for the fibres to breathe and pose health risks. Fibre cement products are widely used in many parts of the world including hospitals and schools.<br> <br> <br> <br> Research has proven that chrysotile's risk is lower to cause illness than amphibole asbestos, like crocidolite and amosite. These amphibole types are the primary cause of mesothelioma, and other asbestos-related diseases. When chrysotile and cement are mixed with cement, a tough product is produced which is able to withstand the most extreme weather conditions and environmental hazards. It is also simple to clean after use. Professionals can safely dispose of asbestos fibres after they have been removed.<br> <br> <br> <br> Amosite<br> <br> <br> <br> Asbestos refers to a group of fibrous silicate minerals that naturally occur in certain types of rock formations. It is classified into six groups: amphibole (serpentine), the tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.<br> <br> <br> <br> Asbestos minerals comprise long, thin fibers that vary in length from fine to broad. They can also be curled or straight. These fibres are found in nature in the form of individual fibrils or bundles with splaying ends referred to as fibril matrix. Asbestos can also be found in a powder form (talc), or combined with other minerals to create talcum powder or vermiculite. They are used extensively in consumer products, including baby powder, cosmetics, and even face powder.<br> <br> <br> <br> Asbestos was extensively used in the first two thirds of the 20th century to construct construction of ships insulation, fireproofing and various other construction materials. The majority of asbestos-related exposures in the workplace occurred in the air, however certain workers were also exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied according to industry, time and geographic location.<br> <br> <br> <br> Most asbestos-related exposures in the workplace were caused by inhalation, however some workers were also exposed through skin contact or through eating contaminated food. Asbestos can only be found in the environment due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles as well as car brakes and clutches, and insulation.<br> <br> <br> <br> There is growing evidence that non-commercial amphibole fibres may also be carcinogenic. These are fibres do not form the tightly woven fibrils of the serpentine and amphibole minerals, but instead are flexible, loose and needle-like. These fibers can be found in cliffs, mountains and sandstones of a variety of countries.<br> <br> <br> <br> Asbestos is able to enter the environment in many ways, such as in airborne particles. It can also be released into soil or water. This can be due to both natural (weathering of asbestos-bearing rock) as well as anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of surface and ground waters is primarily caused through natural weathering. However, it has also been caused by humans, such as through the mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated waste in landfills (ATSDR 2001). Airborne asbestos fibres are the main cause of disease among those exposed to <a href="http://bestone-korea.com/bbs/board.php?bo_table=qa&wr_id=64296">asbestos legal</a> in their job.<br> <br> <br> <br> Crocidolite<br> <br> <br> <br> Inhalation exposure is the most commonly used method of exposure to asbestos fibres. These fibres can enter the lung and cause serious health problems. Mesothelioma, asbestosis and other diseases can be caused by asbestos fibres. Exposure to asbestos fibres can occur in other ways, too, for example, contact with contaminated clothing or building materials. This kind of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite has smaller, more fragile fibers, which are easier to breathe in and may lodge deeper in lung tissue. It has been linked to a higher number of mesothelioma-related cases than any other type of asbestos.<br> <br> <br> <br> The main types are chrysotile as well as amosite. Chrysotile and amosite are among the most commonly used types of asbestos and account for 95 percent of all commercial asbestos that is used. The other four forms haven't been as extensively used however they can be present in older buildings. They are less dangerous than amosite and chrysotile, but they can pose a risk when combined with other <a href="http://gleader.co.kr/bbs/board.php?bo_table=2033&wr_id=2370105">asbestos compensation</a> (<a href="http://www.moneycube.co.kr/bbs/board.php?bo_table=epilogue&wr_id=43771">visit my website</a>) minerals or when mined in close proximity to other naturally occurring mineral deposits, such as vermiculite or talc.<br> <br> <br> <br> Many studies have discovered an association between exposure to asbestos and stomach cancer. Several studies have found a link between <a href="http://www.dae-won.kr/bbs/board.php?bo_table=f02&wr_id=44507">asbestos case</a> exposure and stomach. The evidence is contradictory. Some researchers have reported an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, while others report an SMR of 1,24 (95% confidence interval: 0.76-2.5), for workers in chrysotile mills and mines.<br> <br> <br> <br> The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All kinds of asbestos may cause mesothelioma or other health issues, but the risk is dependent on how much exposure individuals are exposed to, the kind of asbestos used and the duration of their exposure, and the manner in which it is breathed in or consumed. IARC has stated that the best option for individuals is to avoid all forms of asbestos. If you've been exposed in the past to asbestos and suffer from a respiratory condition or mesothelioma then you should consult your GP or NHS111.<br> <br> <br> <br> Amphibole<br> <br> <br> <br> Amphiboles are a grouping of minerals that may form prism-like and needle-like crystals. They are a type of inosilicate mineral that is composed of two chains of SiO4 molecules. They typically have a monoclinic structure in their crystals 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 that are joined in rings of six. Tetrahedrons are distinguished from each other by octahedral sites that are surrounded by strips.<br> <br> <br> <br> Amphiboles are present in metamorphic and igneous rock. They are typically dark and hard. They are sometimes difficult to differentiate from pyroxenes due to their similar hardness and color. They also share a corresponding the cleavage. However their chemistry allows an array of compositions. The chemical compositions and crystal structures of the various mineral groups in amphibole can be used to determine their composition.<br> <br> <br> <br> The five asbestos types in the amphibole class include amosite, anthophyllite and chrysotile and crocidolite. They also include actinolite. Each kind of asbestos has distinct characteristics. The most hazardous type of asbestos, crocidolite, is made up of sharp fibers that are simple to inhale into the lung. Anthophyllite is a brownish to yellowish hue and is comprised primarily of magnesium and iron. It was previously used in cement and insulation materials.<br> <br> <br> <br> Amphiboles are difficult to analyze because of their complex chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires specialized methods. EDS, WDS and XRD are the most popular methods of identifying amphiboles. However, these methods can only provide approximate identifications. For instance, these techniques cannot differentiate between magnesio hornblende and hastingsite. Additionally, these techniques do not distinguish between ferro hornblende and pargasite.
