The Dangers of Exposure to Asbestos Asbestos was used in a variety of commercial products before it was banned. Research has shown that exposure to asbestos can cause cancer and other health issues. It is not possible to tell by simply looking at a thing if it is made of asbestos. Neither can you taste or smell it. Asbestos can only be detected when materials containing it are broken, drilled, or chipped. Chrysotile At its peak, chrysotile made up for 99percent of the asbestos produced. It was employed in a variety of industries including construction, insulation, and fireproofing. In the event that workers were exposed to this harmful material, they could develop mesothelioma or other asbestos related diseases. Thankfully, the use of this toxic mineral has decreased significantly since awareness of mesothelioma began to grow in the 1960's. However, trace amounts of it are still present in many of the products we use in the present. Chrysotile is safe to use when a thorough safety and handling plan is put in place. It has been found that at the present exposure levels, there isn't an undue risk to the workers working with the substance. Inhaling airborne fibres has been found to be strongly linked with lung fibrosis and lung cancer. This has been proven both for the intensity (dose) as in the time of exposure. In one study mortality rates were compared between a facility which used largely Chrysotile for the production of friction materials and the national death rate. The study concluded that, after 40 years of manufacturing low levels of chrysotile, there was no significant increase in mortality at this factory. Chrysotile fibres are typically shorter than other types of asbestos. They are able to penetrate the lungs, and then pass through the bloodstream. This makes them more likely to cause ill-health effects than fibrils with a longer length. It is extremely difficult for chrysotile fibres be inhaled or to pose a health risk when mixed with cement. Fibre cement products are widely used in many parts of the world including hospitals and schools. Research has shown that chrysotile's risk is lower to cause illness than amphibole asbestos such as amosite and crocidolite. These amphibole kinds have been the main source of mesothelioma, as well as other asbestos-related diseases. When chrysotile gets mixed with cement, it forms a strong, flexible construction product that is able to withstand severe conditions in the weather and other environmental dangers. It is also very easy to clean up after use. Asbestos fibres can easily be removed by a professional and safely eliminated. Amosite Asbestos is a grouping of fibrous silicates that are found in various types of rock formations. It is comprised of six general groups: amphibole, serpentine anthophyllite, tremolite and crocidolite (IARC 1973). Asbestos minerals consist of thin, long fibres that range in length, ranging from very thin to broad and straight to curled. They are present in nature as individual fibrils or bundles with splaying ends referred to as fibril matrix. Asbestos minerals can be found in powder form (talc) or mixed with other minerals and sold as vermiculite and talcum powder, which have been widely used in consumer products, such as baby powder cosmetics, face powder and other. The largest asbestos use was during the early two-thirds of the 20th century, when it was used in shipbuilding, insulation, fireproofing and other construction materials. The majority of asbestos exposures for work occurred in the air, but certain workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied from industry industry, from era to and also from geographical location. Most asbestos exposures that workers were exposed to was due to inhalation, but some workers were also exposed through contact with skin or through eating contaminated food. Asbestos can be found in the natural environment due to natural weathering and degradation of contaminated products like ceiling and floor tiles automobile brakes and clutches, and insulation. It is becoming evident that non-commercial amphibole fibres may also be carcinogenic. These are fibres that do not form the tightly weaved fibrils of amphibole or serpentine minerals but instead are flexible, loose and needle-like. These fibres can be found in mountain sandstones, cliffs and sandstones of a variety of countries. Asbestos may enter the environment in a variety of ways, including through airborne particles. It is also able to leach into soil or water. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination of ground and surface water is typically a result of natural weathering, but has also been triggered by anthropogenic activities like mining and milling demolition and dispersal of asbestos-containing materials, and the removal of contaminated dumping ground in landfills (ATSDR, 2001). Asbestos fibres that are emitted from the air are the most significant cause of disease among those exposed to it in their job. Crocidolite Inhalation exposure is the most frequent method of exposure to asbestos fibres. These fibres can enter the lung and cause serious health problems. This includes asbestosis and mesothelioma. Exposure to asbestos fibers can be triggered in other ways, such as contact with contaminated clothing or building materials. The dangers of this kind of exposure are greater when crocidolite (the asbestos' blue form, is involved. Crocidolite fibers are less dense and more fragile, making them easier to inhale. They can also lodge deeper into lung tissue. It has been associated with a higher number of mesothelioma cases than any other type of asbestos. The six major types of asbestos are chrysotile amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. The most popular asbestos types are epoxiemite as well as chrysotile which together comprise the majority of commercial asbestos used. The other four asbestos types are not as well-known, but can still be present in older structures. They are not as dangerous as amosite or chrysotile, but they can still be dangerous when mixed with other minerals or when mined near other mineral deposits such as talc and vermiculite. Many studies have discovered an connection between asbestos exposure and stomach cancer. Several studies have found a link between asbestos exposure and stomach. However there is no conclusive evidence. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95 percent 95% confidence interval: 0.7-3.6) for all asbestos-related workers while other studies have reported an SMR of 1.24 (95% C.I. 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 asbestos types can cause mesothelioma however, the risk is dependent on the amount of exposure, what kind of asbestos is involved, and how long the exposure lasts. IARC has stated that the best choice for individuals is to avoid all types of asbestos. If someone has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma, or other respiratory diseases They should seek advice from their doctor or NHS 111. hialeah asbestos lawsuit is a group of minerals that form long prism or needlelike crystals. They are a type of inosilicate mineral made up of two chains of SiO4 molecules. They have a monoclinic arrangement of crystals, but 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, which are connected in rings of six. The tetrahedrons can be separated from one another by octahedral sites in strips. Amphiboles occur in metamorphic and igneous rock. They are usually dark and hard. Due to their similarity in strength and color, they may be difficult for some people to distinguish from Pyroxenes. They also have a comparable cleavage. Their chemistry can allow for a range of compositions. The chemical compositions and crystal structures of the various mineral groups in amphibole could be used to determine their composition. The five types of asbestos belonging to the amphibole family are chrysotile, anthophyllite, amosite and crocidolite. They also include actinolite. Each type of asbestos comes with its own distinct properties. Crocidolite is the most hazardous asbestos kind. It contains sharp fibers that are easily inhaled into the lungs. Anthophyllite is a brownish to yellowish hue and is made mostly of iron and magnesium. This type of stone was once used in products like cement and insulation materials. Amphiboles are a challenge to analyze due to their complicated chemical structure and the numerous substitutions. A thorough analysis of composition of amphibole minerals requires specialized techniques. The most popular methods of identifying amphiboles include EDS, WDS, and XRD. However, these methods can only provide approximate identifications. For instance, these techniques can't distinguish between magnesio hastingsite and magnesio-hornblende. These techniques also cannot distinguish between ferro-hornblende as well as pargasite.
