The Dangers of Exposure to AsbestosAsbestos was used in a variety of commercial products before it was banned. According to studies, exposure to asbestos can cause cancer and many other health problems.It is not possible to tell by simply looking at a thing if it contains asbestos. Also, you cannot taste or smell it. Asbestos can only be identified when the materials that contain it are broken or drilled.ChrysotileAt its peak, chrysotile accounted for 99% of the asbestos produced. It was employed in many industries which included construction insulation, fireproofing, and construction. If workers are exposed to asbestos, they could develop mesothelioma along with other asbestos-related illnesses. Since the 1960s, when mesothelioma first became a major concern, the use of asbestos has been reduced significantly. However, it is still present in trace amounts. are still present in products that we use in the present.Chrysotile is safe to use provided you have a comprehensive safety and handling program in place. It has been discovered that at the present exposure levels, there is no undue risk to the workers working with it. The inhalation of airborne fibres has been strongly associated with lung cancer and lung fibrosis. This has been proven for the intensity (dose) as well as the duration of exposure.One study that studied the operation of a factory that utilized almost exclusively chrysotile in the production of friction materials, compared the mortality rates of this factory with national death rates. It was found that, over the course of 40 years, processing asbestos chrysotile at low levels of exposure there was no signifi cant extra mortality in the factory.Contrary to other types of asbestos, chrysotile fibers tend to be smaller. They can pass through the lungs and then enter the bloodstream. They are therefore more likely to cause health issues than fibres that are longer.When chrysotile is mixed into cement, it’s extremely difficult for the fibres to be airborne and pose health risks. Fibre cement products are used in many parts of the world including hospitals and schools.Research has revealed that amphibole asbestos like amosite or crocidolite is less likely to cause diseases. These amphibole types have been the most common cause of mesothelioma and other asbestos-related diseases. When chrysotile is combined with cement, it creates a strong, flexible building product that can withstand the most extreme weather conditions and other environmental dangers. It is also easy to clean after use. Asbestos fibres can easily be removed by a professional and safely eliminated.AmositeAsbestos refers to a group of silicate fibrous minerals that naturally occur in certain kinds of rock formations. It is comprised of six general groups: amphibole, serpentine anthophyllite, tremolite and crocidolite (IARC 1973).Asbestos minerals are composed of long, thin fibres that range in length from very fine to broad and straight to curled. These fibres can be found in nature in bundles or individual fibrils. Asbestos can also be found in powder form (talc), or mixed with other minerals to create talcum powder or vermiculite. They are used extensively as consumer products, including baby powder, cosmetics, and even face powder.Asbestos was heavily used in the first two thirds of the 20th century for construction of ships, insulation, fireproofing, and various other construction materials. Most occupational exposures were to airborne asbestos fibres, but some workers were exposed vermiculite and talc that had been contaminated as well as to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied by industry, time period and geographical location.Most asbestos-related exposures in the workplace were caused by inhalation, however certain workers were exposed via skin contact or by eating food contaminated with asbestos. Asbestos can be found in the environment due to natural weathering and degradation of contaminated products like ceiling and floor tiles automobile brakes and clutches, and insulation.It is becoming clear that non-commercial amphibole fibers could also be carcinogenic. These fibres are not tightly weaved like the fibrils that are found in amphibole and serpentine, but are instead loose as well as flexible and needle-like. They can be found in the mountain sandstones, cliffs and sandstones of many countries.Asbestos is able to enter the environment in a variety ways, including in the form of airborne particles. It can also leach out into soil or water. 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 mostly due to natural weathering. However, it has also been caused by human activities such as milling and mining demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated soils for disposal in landfills (ATSDR, 2001). Asbestos fibres that are emitted from the air are the most significant cause of illness in people who are exposed to it during their work.CrocidoliteInhalation exposure is the most frequent method of exposure to asbestos fibres. These fibres can get into the lung, causing serious health problems. Mesothelioma, asbestosis and other diseases are all caused by asbestos fibres. Exposure to fibers can occur in different ways too, for example, contact with contaminated clothing or construction materials. This kind 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 inhale. They can also lodge deeper inside lung tissue. It has been linked to a greater number of mesothelioma cases than any other form of asbestos.The six main types of asbestos are chrysotile amosite, epoxiemite, tremolite anthophyllite, and actinolite. Chrysotile and amosite are among the most commonly used forms of asbestos, and comprise 95 percent of all commercial asbestos in use. The other four asbestos types aren’t as well-known, but can still be found in older structures. They aren’t as hazardous as amosite or chrysotile however they could still be a danger when combined with other minerals or when mined near other mineral deposits, such as vermiculite and talc.Numerous studies have revealed an association between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. However the evidence is not conclusive. Some researchers have cited a SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers, and others report an SMR of 1,24 (95% confidence interval: 0.76-2.5), for those working in chrysotile mills and mines.The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All asbestos types can cause mesothelioma, but the risk is different based on the amount of exposure, the type of asbestos is involved and how long exposure lasts. IARC has stated that the best choice for individuals is to avoid all forms of asbestos. If someone has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma or other respiratory ailments, they should seek guidance from their doctor or NHS 111.AmphiboleAmphiboles comprise a variety of minerals which can form needle-like or prism-like crystals. They are an inosilicate mineral composed of double chains of SiO4 molecules. They usually have a monoclinic crystal structure but some also have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains comprise (Si, Al)O4 tetrahedrons linked together by tetrahedron rings made of six. The tetrahedrons are separated from each other by strips of octahedral sites.Amphiboles occur in both igneous and metamorphic rock. They are typically dark and hard. They can be difficult to distinguish from pyroxenes due to their similar hardness and colors. They also share a similar the cleavage pattern. Their chemistry allows a wide variety of compositions. The various mineral groups within amphibole are identified by their chemical compositions as well as crystal structures.Amphibole asbestos consists of chrysotile, and the five types of asbestos amosite, anthophyllite (crocidolite) amosite (actinolite) and amosite. The most widely used form of asbestos is chrysotile; each has its own unique characteristics. Crocidolite is the most dangerous asbestos type. It is composed of sharp fibers that can be easily breathed into the lung. columbia asbestos lawyer 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.Amphibole minerals are difficult to analyze because they have a a complicated chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires special techniques. The most widely used methods to identify amphiboles are EDS, WDS, and XRD. These methods are only able to provide approximate identifications. These methods, for instance cannot differentiate between magnesio-hornblende and hastingsite. These techniques also don’t differentiate between ferro-hornblende or pargasite.
