The Dangers of Exposure to Asbestos Before it was banned, asbestos was widely used in commercial products. Studies have shown that exposure to asbestos can cause cancer and other health problems. You cannot tell if something has asbestos just simply by looking at it and you can't smell or taste it. It is only found when the asbestos-containing materials are drilled, chipped or broken. Chrysotile At its height, chrysotile was responsible for 99% of the asbestos made. It was employed in many industries, including construction insulation, fireproofing and insulation. If workers were exposed to the toxic material, they may develop mesothelioma and other asbestos-related diseases. Thankfully, the use of this harmful mineral has diminished dramatically since mesothelioma awareness began to grow in the 1960's. It is still present in a variety of products we use in the present. Chrysotile can be used safely when a thorough safety and handling plan is in place. It has been proven that at the present exposure levels, there isn't an danger to those working with the substance. Inhaling airborne fibers has been found to be strongly linked with lung cancer and lung fibrosis. This has been proven for the intensity (dose) as well as the duration of exposure. In one study, mortality rates were compared between a manufacturing facility which used largely Chrysotile for the production of friction materials and the national death rate. It was found that over the course of 40 years, processing asbestos chrysotile at a low level of exposure there was no significant extra mortality in the factory. In contrast to other forms of asbestos, chrysotile fibres tend to be shorter. They can enter the lungs and enter the bloodstream. This makes them more likely to cause health effects than fibres with longer lengths. When chrysotile is mixed into cement, it is extremely difficult for the fibres to air-borne and pose any health risk. Fibre cement products are used extensively throughout the world particularly in structures like hospitals and schools. fort smith asbestos attorney has shown that amphibole asbestos such as crocidolite or amosite is less likely than chrysotile to cause diseases. These amphibole kinds have been the main source of mesothelioma, as well as other asbestos-related illnesses. When chrysotile and cement are mixed with cement, a tough and flexible product is created that can withstand extreme weather conditions and environmental hazards. It is also easy to clean up after use. Professionals can safely get rid of asbestos fibres after they have been removed. Amosite Asbestos is one of the groups of fibrous silicates found in a variety of rock formations. It is divided into six groups including amphibole (serpentine), the tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are made up of thin, long fibers that range in length from extremely fine to wide and straight to curled. They are found in nature in bundles, or as individual fibrils. Asbestos can also be found in powder form (talc) or combined with other minerals to form vermiculite or talcum powder. They are extensively used as consumer goods, such as baby powder, cosmetics, and even face powder. The most extensive use of asbestos occurred in the first two-thirds of the 20th century when it was utilized in insulation, shipbuilding, fireproofing and other construction materials. The majority of asbestos-containing exposures to the workplace were in the air, but some workers also were exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied from industry to industry, era to era and geographic location. Asbestos exposure in the workplace is mainly because of inhalation. However certain workers have been exposed by contact with their skin or by eating food items contaminated with asbestos. Asbestos is only found in the environment because of natural weathering and degrading of products that are contaminated like ceiling and floor tiles, car brakes and clutches, as well as insulation. There is emerging evidence that non-commercial amphibole fibres may also be carcinogenic. These fibers aren't tightly woven like the fibrils found in serpentine and amphibole, but are instead loose as well as flexible and needle-like. They can be found in the mountains, sandstones and cliffs of many countries. Asbestos is absorbed into the environment mostly as airborne particles, but it can also leach into soil and water. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination in surface and ground waters is primarily caused through natural weathering. However, it has also been caused by humans, such as 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 most significant reason for illness among those exposed to it in their job. Crocidolite Inhalation exposure to asbestos is the most popular way people are exposed to the harmful fibres. They can be absorbed into the lungs and cause serious health issues. These include asbestosis and mesothelioma. Exposure to asbestos fibers can be triggered in other ways, including contact with contaminated clothes or building materials. This kind of exposure is more hazardous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are thinner and more fragile, making them easier to breathe. They also can get deeper inside lung tissue. It has been linked to more mesothelioma cases than other types of asbestos. The six major types of asbestos are chrysotile amosite as well as epoxiemite. Tremolite is anthophyllite and actinolite. The most common asbestos types are epoxiemite as well as chrysotile which together comprise 95% all commercial asbestos used. The other four asbestos types are not as widespread, but they can still be present in older structures. They are not as dangerous as amosite or chrysotile but still be a danger when mixed with other minerals or when mined near other naturally occurring mineral deposits like talc and vermiculite. Numerous studies have demonstrated the connection between stomach cancer and asbestos exposure. However the evidence is not conclusive. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, whereas others have reported an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those working in chrysotile mines or chrysotile mills. The International Agency for Research on Cancer (IARC) has classed all forms of asbestos 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 exposure lasts. The IARC has recommended that avoiding all forms of asbestos is the most important thing to do because this is the best option for people. However, if a person has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma and other respiratory diseases They should seek advice from their physician or NHS 111. Amphibole Amphibole is one of the minerals that form long prisms or needlelike crystals. They are a type of silicate mineral made up of double chains of molecules of SiO4. They have a monoclinic structure of crystals, but certain crystals have an orthorhombic form. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are made up of (Si,Al)O4 Tetrahedrons which are connected in rings of six. The tetrahedrons are separated from each other by octahedral sites in strips. Amphiboles are present in metamorphic and igneous rock. They are typically dark and hard. Due to their similarity in strength and color, they could be difficult for some people to distinguish from the pyroxenes. They also share a similar cut. However their chemistry allows a wide range of compositions. The different mineral groups within amphibole are identified by their chemical compositions as well as crystal structures. Amphibole asbestos comprises chrysotile and the five types of asbestos: amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. Each type of asbestos has its own distinctive properties. Crocidolite is the most dangerous asbestos type. It is composed of sharp fibers that can easily be breathed into the lung. Anthophyllite is a brownish to yellowish color and is made mostly of iron and magnesium. This type of stone was once used in products such as cement and insulation materials. Amphibole minerals are hard to analyze because they have a complex chemical structures and numerous substitutions. An in-depth analysis of the composition of amphibole minerals is a complex process that requires specialized methods. The most commonly used methods to identify amphiboles are EDS, WDS, and XRD. These methods can only provide approximate identifications. For instance, these methods cannot distinguish between magnesiohastingsite and magnesio-hornblende. In addition, these techniques can not distinguish between ferro-hornblende or pargasite.
