The Dangers of Exposure to Asbestos Asbestos was found in thousands of commercial products prior to when it was banned. Studies have shown that exposure to asbestos can cause cancer and other health problems. You cannot tell if something is asbestos-containing by looking at it, and you are unable to taste or smell it. miami gardens asbestos law firm is only detected when the materials that contain it are broken or drilled. Chrysotile At its height, chrysotile was responsible for 99% of the asbestos created. It was used by many industries such as construction insulation, fireproofing and insulation. If workers are exposed to asbestos, they can develop mesothelioma along with other asbestos-related diseases. Thankfully, the use of this dangerous mineral has decreased significantly since awareness of mesothelioma began to spread in the 1960's. However, trace amounts of it remain in the products we use in the present. Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. Personnel handling chrysotile aren't at risk of being exposed to a high degree of risk at the present controlled exposure levels. Lung fibrosis, lung cancer and mesothelioma were all linked to breathing in airborne respirable fibres. This has been confirmed both in terms of intensity (dose) as well as the duration of exposure. One study that looked into an industrial facility that used almost exclusively chrysotile to manufacture friction materials, compared mortality rates at this factory with national death rates. The study revealed that after 40 years of processing at low levels of chrysotile, there was no significant increase in mortality in this factory. Chrysotile fibres tend to be shorter than other types of asbestos. They can enter the lungs and enter the bloodstream. This makes them much more likely to cause ill-health consequences than longer fibres. It is extremely difficult for chrysotile fibres to be in the air or pose a health risk when mixed with cement. Fibre cement products are widely used in many parts of the world, including schools and hospitals. Studies have shown that chrysotile is less likely to cause illness than amphibole asbestos like amosite and crocidolite. These amphibole varieties are the main cause of mesothelioma, and other asbestos-related diseases. When cement and chrysotile are mixed and cured, a tough and flexible material is created which is able to withstand the most extreme weather conditions and environmental hazards. It is also easy to clean up after use. Asbestos fibers can be easily removed by a professional and taken away. Amosite Asbestos is a term used to describe a class of fibrous silicate minerals that are found naturally in specific 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 vary in length, ranging from very fine to wide and straight to curled. 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 make talcum powder or vermiculite. These are commonly used in consumer products such as baby powder cosmetics and facial powder. Asbestos was widely used during the early two-thirds of the 20th century to construct construction of ships insulation, fireproofing, insulation and various other construction materials. Most occupational exposures were to asbestos fibres borne by air, but certain workers were exposed to vermiculite and talc that had been contaminated, and to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied from industry industry, from era to, and geographical location. Exposure to asbestos in the workplace is mostly caused by inhalation. However certain workers have been exposed by contact with their skin or eating contaminated foods. Asbestos is found in the natural environment due to natural weathering and degrading of products that are contaminated like ceiling and floor tiles as well as car brakes and clutches, as well as insulation. There is evidence emerging that non-commercial amphibole fibres may also be carcinogenic. These fibers aren't tightly weaved like the fibrils that are found in amphibole or serpentine, they are loose elastic, flexible, and needle-like. These fibers are found in the mountains and cliffs of several countries. Asbestos can enter the environment in a variety 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) and anthropogenic causes (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is largely associated with natural weathering, however it has also been caused by anthropogenic activities like mining and milling, demolition and dispersal of asbestos-containing materials and the disposal of contaminated dumping soils in landfills (ATSDR, 2001). Inhalation exposure to asbestos fibres is still the primary reason for illness among those exposed to asbestos at work. Crocidolite Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can enter the lung and cause serious health issues. Mesothelioma, asbestosis and other diseases are all caused by asbestos fibres. Exposure to asbestos fibres can occur in different ways, including contact with contaminated clothing or building materials. The dangers of exposure are heightened when crocidolite (the asbestos in the blue form is involved. Crocidolite is a smaller, more fragile fibers, which are easier to breathe and can be lodged deeper into lung tissue. It has been associated with more mesothelioma cases than other types of asbestos. The six main types of asbestos are chrysotile, amosite, epoxiemite, tremolite anthophyllite and actinolite. The most common forms of asbestos are epoxiemite and chrysotile which together make up 95% all commercial asbestos employed. The other four asbestos types are not as well-known, but can still be present in older structures. They are less hazardous than amosite and chrysotile. However, they may pose a danger when mixed with other asbestos minerals or mined close to other mineral deposits, such as talc or vermiculite. Numerous studies have revealed an association between exposure to asbestos and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. The evidence is not conclusive. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% CI: 0.7-3.6) for all asbestos-related workers and 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 forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma, however the risks differ based on how much exposure, what kind of asbestos is involved, and how long the exposure lasts. IARC has declared that the best choice for people is to avoid all forms of asbestos. If you have been exposed to asbestos and suffer from a respiratory illness or mesothelioma, then you should talk to your doctor or NHS111. Amphibole Amphiboles are groups of minerals that form prism-like or needle-like crystals. They are a type inosilicate mineral composed of double chains of molecules of SiO4. They usually have a monoclinic structure in their crystals but some also have 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. Tetrahedrons can be separated by octahedral strips. Amphiboles can be found in metamorphic and igneous rock. They are typically dark and hard. They can be difficult to distinguish from pyroxenes due to their similar hardness and color. They also have a similar cleavage. However their chemistry permits many different compositions. The various mineral groups within amphibole are identified by their chemical compositions as well as crystal structures. The five types of asbestos belonging to the amphibole family are amosite, anthophyllite, crocidolite, and actinolite. Each kind of asbestos has its own distinct properties. Crocidolite is the most hazardous asbestos kind. It is composed of sharp fibers that can be easily inhaled into the lung. Anthophyllite is yellowish to brown in color and is composed of iron and magnesium. This type was used to make cement and insulation materials. Amphibole minerals are hard to analyze due to their complex chemical structures and numerous substitutions. An in-depth analysis of the composition of amphibole minerals is a complex process that requires specialized techniques. The most popular methods for identifying amphiboles are EDS, WDS, and XRD. However, these methods only give approximate identifications. For instance, these methods cannot distinguish between magnesiohastingsite and magnesio-hornblende. These techniques do not distinguish between ferro-hornblende and pargasite.
