The Dangers of Exposure to AsbestosAsbestos was found in thousands of commercial products before it was banned. Research shows that exposure to asbestos can cause cancer and other health problems.It is difficult to tell if something includes asbestos by looking at it and you are unable to taste or smell it. It is only visible when asbestos-containing materials are drilled, chipped or broken.ChrysotileAt its peak, chrysotile made up for 99percent of the asbestos produced. It was used in many industries including construction, insulation, and fireproofing. In the event that workers were exposed to the toxic material, they could contract mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma first became a concern the use of asbestos has decreased significantly. However, traces of it can still be found in many of the products we use today.Chrysotile can be used in a safe manner if a thorough safety and handling plan is put into place. It has been discovered that at the present exposure levels, there isn't an danger to the people handling the substance. The inhalation of airborne particles has been strongly associated with lung fibrosis and lung cancer. This has been confirmed for intensity (dose) as well as duration of exposure.In one study, mortality rates were compared between a manufacturing facility that used a large proportion of Chrysotile for the production of friction materials and national death rates. It was found that for the 40 years of processing asbestos chrysotile in low levels of exposure there was no significant extra mortality in the factory.Chrysotile fibres tend to be shorter than other types of asbestos. They can enter the lungs, and even enter the bloodstream. This makes them much more likely to cause ill-health effects than longer fibres.It is very difficult for chrysotile fibres to be airborne or pose any health risk when mixed with cement. Fibre cement products are used in a variety of locations around the world including hospitals and schools.Research has revealed that chrysotile is less prone to cause disease than amphibole asbestos, like crocidolite and amosite. Amphibole types like these are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile mixes with cement, it forms a strong, flexible construction product that is able to withstand severe 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.AmositeAsbestos is a term used to describe a class of silicate minerals with fibrous structure that are found naturally in specific kinds of rock formations. It is composed of six general groups: serpentine, amphibole anthophyllite, tremolite and crocidolite (IARC, 1973).Asbestos minerals consist of long, thin fibers that vary in length from fine to broad. They can also be curled or straight. These fibres can be found in nature in bundles, or as individual fibrils. Asbestos is also found in a powder form (talc) or combined with other minerals to create vermiculite or talcum powder. These are commonly used in consumer products including baby powder, cosmetics, and face powder.Asbestos was widely used during the early two-thirds of the 20th century for shipbuilding insulation, fireproofing and other construction materials. The majority of occupational exposures involved asbestos fibres that were borne in the air, but certain workers were exposed to vermiculite or talc that was contaminated, and to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied according to industry, time period and geographic location.Exposure to asbestos at work is mostly due to inhalation. However, some workers have been exposed via skin contact or by eating food items contaminated with asbestos. Asbestos can only be found in the air due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles automobile brakes and clutches, and insulation.There is growing evidence that non-commercial amphibole fibres may also be carcinogenic. These fibres are not tightly knit like the fibrils found in amphibole and serpentine, they are loose and flexible, and needle-like. These fibers are found in the mountains and cliffs of several countries.Asbestos is able to enter the environment in a variety ways, such as in airborne particles. It can also be absorbed into water or soil. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination of ground and surface water is mostly a result of natural weathering, but it has also been caused by anthropogenic activities like milling and mining, demolition and dispersal of asbestos-containing materials, and the removal of contaminated dumping soil in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary cause of disease among those exposed to it in their occupation.CrocidoliteInhalation exposure is the most frequent method of exposure to asbestos fibres. The fibres can penetrate the lung, causing serious health problems. Mesothelioma, asbestosis, and other illnesses can be caused by asbestos fibres. The exposure to asbestos fibres could also take place in other ways, such as contact with contaminated clothing or building materials. The dangers of this kind of exposure are heightened when crocidolite (the blue form of asbestos is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe in and may lodge deeper in lung tissue. It has been linked to more mesothelioma cases than other asbestos types.The six major types of asbestos are chrysotile, amosite as well as epoxiemite. Tremolite is anthophyllite, and actinolite. Chrysotile and amosite are among the most commonly used forms of asbestos and account for 95% of the commercial asbestos currently used. The other four types of asbestos haven't been as widely used, but they may still be found in older buildings. They are less dangerous than amosite and chrysotile. However, they may pose a danger when mixed with other asbestos minerals, or when mined in close proximity to other naturally occurring mineral deposits, like vermiculite or talc.Numerous studies have revealed the connection between stomach cancer and asbestos exposure. 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, while others have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for those working in chrysotile mines or chrysotile mills.IARC, the International Agency for Research on Cancer has classified all types of asbestos 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 the exposure lasts. The IARC has recommended that avoid all forms of asbestos should be the top priority as it is the safest option for individuals. If you have been exposed to asbestos and are suffering from a respiratory disorder or mesothelioma condition, then you should see your physician or NHS111.mission asbestos attorneys is one of the minerals that form long prisms or needlelike crystals. They are a type inosilicate mineral made up of two chains of molecules of SiO4. They are a monoclinic system of crystals, but some exhibit 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 can be separated from each other by strips of octahedral sites.Amphiboles can be found in both igneous and metamorphic rock. They are usually dark and hard. They can be difficult to differentiate from pyroxenes since they share similar hardness and colors. They also have a comparable cleavage. However their chemistry allows an array of compositions. The chemical compositions and crystal structure of the various mineral groups found in amphibole may be used to determine their composition.The five types of asbestos in the amphibole family include amosite, anthophyllite as well as crocidolite and actinolite. Each type of asbestos has its own unique properties. The most hazardous type of asbestos, crocidolite is made up of sharp fibers that are simple to breathe into the lungs. Anthophyllite is a brownish to yellowish color and is made primarily of magnesium and iron. This variety was once used in cement and insulation materials.Amphibole minerals are hard to analyze because they have a an intricate chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires specialized techniques. EDS, WDS and XRD are the most commonly used methods of identifying amphiboles. However, these methods only give approximate identifications. These techniques, for example can't distinguish between magnesio-hornblende and hastingsite. These techniques also do not differentiate between ferro-hornblende or pargasite.
