The Dangers of Exposure to Asbestos Before it was banned asbestos was used in a myriad of commercial products. Studies have shown that exposure to asbestos can cause cancer and other health problems. You cannot tell by just looking at something if it's made of asbestos. You cannot smell or taste it. It is only discovered when the asbestos-containing materials are drilled, chipped or broken. Chrysotile At its height, chrysotile provided for 99percent of the asbestos created. It was widely used in industries such as construction insulation, fireproofing and insulation. If workers were exposed to this harmful material, they could develop mesothelioma and other asbestos-related diseases. Since the 1960s, when mesothelioma began to become a problem asbestos use has been reduced significantly. However, trace amounts are still present in many of the products we use in the present. Chrysotile is safe to use provided you have a comprehensive safety and handling plan in place. It has been discovered that at the current controlled exposure levels, there isn't an danger to those who handle the substance. The inhalation of airborne fibres has been strongly associated with lung fibrosis and lung cancer. This has been proven for the intensity (dose) as and the duration of exposure. A study that looked at a facility that used nearly exclusively chrysotile to manufacture friction materials, compared mortality rates at this factory with national mortality rates. The study concluded that, after 40 years of manufacturing low levels of chrysotile, there was no significant increase in mortality rates in this factory. Contrary to other types of asbestos, chrysotile fibres tend to be smaller. They can pass through the lungs, and enter the bloodstream. This makes them much more prone to causing health consequences than longer fibres. When chrysotile mixes with cement, it is extremely difficult for the fibres to become airborne and pose any health risk. The fibre cement products are extensively used throughout the world particularly in structures such as schools and hospitals. Research has revealed that chrysotile has a lower chance to cause disease than amphibole asbestos, like amosite and crocidolite. Amphibole asbestos types have been the most common cause of mesothelioma and other asbestos-related diseases. When cement and chrysotile mix with cement, a tough and flexible material is created which is able to withstand the most extreme environmental hazards and weather conditions. It is also very easy to clean after use. Asbestos fibers can be easily removed by a professional and then safely disposed of. Amosite Asbestos refers to a set of silicate mineral fibrous which are found naturally in a variety of kinds of rock formations. It is comprised of six general groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC 1973). Asbestos minerals consist of long, thin fibers that range in length from fine to broad. They can be curled or straight. These fibers are found in nature as individual fibrils, or as bundles with splaying ends referred to as fibril matrix. Asbestos minerals are also found in the form of a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder that are widely used in consumer products like baby powder, face powder and cosmetics. Asbestos was heavily used in the first two thirds of the 20th century to construct shipbuilding as well as insulation, fireproofing and various other construction materials. Most occupational exposures were asbestos fibres in the air, however some workers were exposed toxic talc or vermiculite as well as to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied by the industry, time frame and geographic location. Most of the occupational exposures to asbestos were due to inhalation, but some workers were also exposed by skin contact or by eating food contaminated with asbestos. Asbestos can be found in the air due to natural weathering of mined ores and deterioration of contaminated products such as 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 woven like the fibrils found in amphibole and serpentine they are loose, flexible, and needle-like. These fibers can be found in the cliffs and mountains in a variety of countries. Asbestos is able to enter the environment in a variety of ways, including through airborne particles. It can also be absorbed into water or soil. 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 water is mostly due to natural weathering. However, it has also been caused by human activities such as mining and milling demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated dumping ground in landfills (ATSDR 2001). Airborne asbestos fibres are the most significant reason for illness among those who are exposed to it during their job. Crocidolite Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can infiltrate the lungs, causing serious health problems. Mesothelioma as well as asbestosis and other diseases can be caused by asbestos fibres. Exposure to asbestos fibers can also take place in other ways, including contact with contaminated clothes or building materials. This kind of exposure is more hazardous when crocidolite (the blue asbestos form) is involved. Crocidolite is smaller and more fragile fibers, which are easier to inhale and can lodge deeper in lung tissue. It has been linked to more mesothelioma-related cases than other asbestos types. The six major kinds are chrysotile and amosite. The most common asbestos types are epoxiemite and chrysotile which together comprise 95% all commercial asbestos used. The other four asbestos types aren't as well-known, but can still be present in older structures. They are not as dangerous as chrysotile or amosite but can still be dangerous when combined with other minerals or when mined near other mineral deposits, such as vermiculite and talc. Numerous studies have shown that there is a link between stomach cancer and asbestos exposure. The evidence is contradictory. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for workers in chrysotile mines and mills. IARC, the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All asbestos types can cause mesothelioma however the risks differ based on the amount of exposure, what type of asbestos is involved, and how long exposure lasts. IARC has declared that the best choice for people is to stay clear of all forms of asbestos. If you've been exposed to asbestos and are suffering from a respiratory illness or mesothelioma, you should consult your GP or NHS111. Amphibole Amphiboles are groups of minerals that may create prism-like or needle-like crystals. They are a kind of inosilicate mineral that is composed of double chains of molecules of SiO4. They have a monoclinic arrangement of crystals, however some exhibit 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 series of six tetrahedrons. Tetrahedrons may be separated by octahedral strips. Amphiboles can be found in metamorphic and igneous rock. They are typically dark-colored and are hard. They can be difficult to differentiate from pyroxenes as they share similar hardness and color. They also have a similar the cleavage. Their chemistry can allow for a variety of compositions. The various amphibole mineral groups are identified by their chemical compositions as well as crystal structures. Amphibole asbestos includes chrysotile and the five types of asbestos amosite anthophyllite (crocidolite), amosite (actinolite) and amosite. corona asbestos attorneys of asbestos comes with distinct characteristics. The most dangerous form of asbestos, crocidolite is composed of sharp fibers that are easy to inhale into the lungs. Anthophyllite is brown to yellowish in color and is composed of iron and magnesium. This kind of stone was used to create cement and insulation materials. Amphiboles are difficult to analyze due to their complex chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires special techniques. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods only provide approximate identifications. These techniques, for example, cannot distinguish between magnesio hastingsite and magnesio hastingsite. These techniques also do not distinguish between ferro-hornblende and.
