The Dangers of Exposure to Asbestos Asbestos was used in thousands of commercial products before it was banned. According to research, asbestos exposure can cause cancer as well as other health issues. It is not possible to tell by simply taking a look at something if it contains asbestos. Also, bloomington asbestos attorneys cannot taste or smell it. Asbestos can only be identified when the substances that contain it are broken or drilled. Chrysotile At the height of its use, chrysotile made up 99% of the asbestos production. It was used in many industries like construction insulation, fireproofing, and insulation. If workers are exposed to asbestos, they can develop mesothelioma and other asbestos-related illnesses. Since the 1960s, when mesothelioma was first becoming a problem the use of asbestos has been reduced significantly. It is still present in many of the products we use today. Chrysotile is safe to use when a thorough safety and handling plan is put into place. It has been proven that at the current controlled exposure levels, there is no unneeded risk to the people working with it. Lung cancer, lung fibrosis and mesothelioma were all associated with breathing in airborne respirable fibres. This has been proven to be true for both the intensity (dose) and the duration of exposure. In one study mortality rates were compared between a manufacturing facility that used a large proportion of Chrysotile in the production of friction materials and national death rates. It was concluded that for the 40 years of processing asbestos chrysotile at a low level of exposure there was no signifi cant increase in mortality in this particular 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 likely to cause ill-health effects than fibrils with a longer length. It is extremely difficult for chrysotile fibers to be airborne or pose any health risk when mixed with cement. Fibre cement products are used in various parts of the world including hospitals and schools. Research has revealed that chrysotile is less likely to cause disease than amphibole asbestos, such as crocidolite and amosite. These amphibole types are the main source of mesothelioma as well as other asbestos-related diseases. When chrysotile and cement are mixed and cured, a tough, flexible product is created that is able to withstand extreme weather conditions and environmental hazards. It is also easy to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed. Amosite Asbestos is a term used to describe a class of silicate fibrous minerals which are found naturally in a variety of kinds of rock formations. It is classified into six groups: amphibole (serpentine), Tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are composed of thin, long fibers that vary in length from extremely fine to broad and straight to curled. These fibres can be found in nature as bundles or individual fibrils. Asbestos minerals can be found as a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder that are widely used in consumer products, such as baby powder cosmetics, face powder and baby powder. The heaviest asbestos use occurred during the first two-thirds of 20th century where it was used in shipbuilding, insulation, fireproofing, and other construction materials. The majority of asbestos exposures for work were in the air, however some workers also were exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied according to the industry, time frame and geographical location. Most of the asbestos-related exposures in the workplace were caused by inhalation, however some workers were also exposed through contact with skin or through eating contaminated food. Asbestos is currently only found in the environment due to the natural weathering of mined minerals and deterioration of contaminated products like insulation, car brakes, clutches, and floor and ceiling tiles. It is becoming apparent that amphibole fibers that are not commercially available could also be carcinogenic. These fibres are not tightly weaved like the fibrils in serpentine and amphibole, they are loose and flexible, and needle-like. These fibres can be found in mountains, sandstones, and cliffs in a variety of countries. Asbestos is able to enter the environment in many ways, including through airborne particles. It can also leach out into water or soil. This can be triggered by both natural (weathering of asbestos-bearing rock) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground waters is primarily due to natural weathering. However it is also caused by human activity, for instance through mining and milling of asbestos-containing materials demolition and dispersal and the disposal of contaminated waste in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the main cause of disease among those exposed to asbestos during their job. Crocidolite Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can enter the lungs and cause serious health problems. These include asbestosis and mesothelioma. The exposure to asbestos can happen in other ways as well including contact with contaminated clothing or construction materials. The risks of exposure are higher when crocidolite, the asbestos that is blue is involved. Crocidolite fibers are smaller and more fragile making them more palatable to breathe. They can also lodge deeper within lung tissues. It has been linked to a higher number of mesothelioma related cases than any other form of asbestos. The six primary types are chrysotile and amosite. The most common asbestos types are epoxiemite and chrysotile, which together comprise the majority of commercial asbestos employed. The other four types of asbestos haven't been as widely used however, they could be found in older buildings. They aren't as hazardous as amosite or chrysotile, but they can still be dangerous when mixed with other minerals or when mined close to other mineral deposits, such as talc and vermiculite. Numerous studies have proven that there is a link between stomach cancer and asbestos exposure. The evidence is contradictory. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all asbestos-related workers while other studies have reported an SMR of 1.24 (95 percent of the CI = 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 carcinogenic. All forms of asbestos could cause mesothelioma and other health issues, however the risk is dependent on the amount of exposure people are exposed to, the type of asbestos used as well as the length of their exposure and the method by which it is breathed in or consumed. The IARC has advised that avoid all forms of asbestos should be the highest priority, as this is the safest option for individuals. If you've been exposed in the past to asbestos and are suffering from a respiratory illness or mesothelioma condition, then you should see your physician or NHS111. Amphibole Amphibole is a group of minerals that form long prisms or needle-like crystals. They are a type inosilicate mineral made up of double chains of molecules of SiO4. They have a monoclinic system of crystals, but some have an orthorhombic shape. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. Double chains contain (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. Tetrahedrons are distinguished from each other by octahedral sites that are surrounded by strips. Amphiboles can be found in metamorphic and igneous rock. They are usually dark-colored and are hard. They can be difficult to distinguish from pyroxenes since they share similar hardness and colors. They also share a similar design of cleavage. Their chemistry permits a wide range of compositions. The different minerals within amphibole can be identified by their chemical compositions and crystal structures. The five asbestos types in the amphibole family include chrysotile, anthophyllite, amosite, crocidolite, and actinolite. While the most commonly used form of asbestos is chrysotile each type has its own distinct characteristics. Crocidolite is considered to be the most hazardous asbestos kind. It is composed of sharp fibers that can easily be breathed 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 can be difficult to study because of their an intricate chemical structure and numerous substitutions. A detailed analysis of the composition of amphibole mineral requires specialized techniques. EDS, WDS and XRD are the most popular methods of identifying amphiboles. These methods can only provide approximate identifications. For instance, these methods cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques also don't distinguish between ferro-hornblende as well as pargasite.
