The Dangers of Exposure to Asbestos Before it was banned asbestos was used in a myriad of commercial products. Research shows that exposure to asbestos can cause cancer and other health problems. You cannot tell if something is asbestos-containing simply by looking at it and you can't smell or taste it. Asbestos can only be detected when materials containing it are broken, drilled, or chipped. Chrysotile At its height, chrysotile was responsible for 99percent of the asbestos created. It was widely used in industries including construction insulation, fireproofing, as well as insulation. If workers are exposed to asbestos, they may develop mesothelioma or other asbestos-related illnesses. Since the 1960s, when mesothelioma began to become a concern the use of asbestos has declined significantly. However, trace amounts of it are still present in many of the products we use today. Chrysotile is safe to use when you have a thorough safety and handling plan in place. People who handle chrysotile do not at risk of being exposed to a high degree of risk at the current safe exposure levels. Lung fibrosis, lung cancer and mesothelioma have been strongly associated with breathing in airborne respirable fibres. This has been confirmed for the intensity (dose) as well as duration of exposure. In one study mortality rates were compared between a facility that used a large proportion of Chrysotile in the production of friction materials and national death rates. It was concluded that for 40 years of preparing chrysotile asbestos at low levels of exposure there was no significant additional mortality in this factory. Unlike some other forms of asbestos, chrysotile fibers tend to be smaller. They can pass through the lungs, and enter the bloodstream. They are therefore more likely to cause health problems over longer fibres. When chrysotile is mixed with cement, it is extremely difficult for the fibres to become airborne and pose any health risk. The fibre cement products are used extensively throughout the world, especially in buildings like hospitals and schools. Research has shown that amphibole asbestos such as amosite or crocidolite is less likely than chrysotile in causing disease. pasadena asbestos lawyer are the primary source of mesothelioma as well as other asbestos-related diseases. When chrysotile and cement are mixed with cement, a tough and flexible product is created which is able to withstand the most extreme weather conditions and environmental hazards. It is also simple to clean after use. Professionals can safely remove asbestos fibres once they have been removed. Amosite Asbestos is a category of silicate fibrous minerals which are found naturally in a variety of types of rock formations. It is classified into six groups: amphibole (serpentine) and the tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals comprise long, thin fibers that vary in length from fine to broad. They can also be curled or straight. They are present in nature as individual fibrils or bundles with splaying ends called fibril matrix. Asbestos can also be found in a powder form (talc) or mixed with other minerals to create vermiculite or talcum powder. They are extensively used in consumer products such as baby powder cosmetics, and face powder. The most extensive use of asbestos was in the first two-thirds of twentieth century when it was utilized in insulation, shipbuilding, fireproofing, and other construction materials. The majority of occupational exposures were asbestos fibres borne by air, but some workers were exposed vermiculite or talc that was contaminated and also to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied by industry, time period and geographic location. Most of the occupational exposures to asbestos were due to inhalation. However, certain workers were exposed by skin contact or through eating contaminated food. Asbestos can only be found in the environment because of natural weathering and degrading of contaminated materials like ceiling and floor tiles as well as car brakes and clutches as well as insulation. It is becoming apparent that non-commercial amphibole fibers could also be carcinogenic. These are fibers that don't form the tightly woven fibrils of the serpentine and amphibole minerals, but instead are flexible, loose and needle-like. These fibers are found in cliffs, mountains and sandstones in a variety of countries. Asbestos can enter the environment in many ways, including in the form of airborne particles. It can also be released into water or soil. This can be caused by both natural (weathering of asbestos-bearing rock) as well as anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is mostly due to natural weathering, but it 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). Inhalation exposure to asbestos fibres is the most common cause of illness in people exposed to asbestos at work. Crocidolite Inhalation exposure is the most commonly used method of exposure to asbestos fibres. These fibres can infiltrate the lung and cause serious health issues. These include mesothelioma and asbestosis. Exposure to asbestos fibers can occur in different ways, such as contact with contaminated clothes or building materials. The risks of exposure are higher when crocidolite (the asbestos' blue form is involved. Crocidolite is a smaller, more fragile fibers, which are easier to breathe in and can get deeper into lung tissue. It has been linked to a greater number of mesothelioma-related cancers than any other type of asbestos. The six main types are chrysotile and amosite. The most well-known forms of asbestos are chrysotile and epoxiemite, which together make up the majority of commercial asbestos employed. The other four asbestos types are not as common, but may still be present in older structures. They are not as dangerous as chrysotile or amosite but can still be a risk when mixed with other minerals, or when mined near other mineral deposits like talc and vermiculite. Several studies have found an association between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. The evidence is not conclusive. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all workers exposed to asbestos as well as an SMR of 1.24 (95% C.I. 0.76-2.5) for workers in chrysotile mines and 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 risks differ based on how much exposure, what type of asbestos is involved, and how long the exposure lasts. The IARC has advised that the prevention of all asbestos types is the most important thing to do as it is the most secure option for people. However, if someone has been exposed to asbestos in the past and are suffering from a condition such as mesothelioma or other respiratory ailments and require advice, they should seek out guidance from their doctor or NHS 111. Amphibole Amphiboles comprise a variety of minerals that form needle-like or prism-like crystals. They are a type inosilicate mineral made up of two chains of SiO4 molecules. They have a monoclinic system 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 linked together in a ring of six tetrahedrons. Tetrahedrons can be separated by octahedral strips. Amphibole minerals are found in metamorphic and igneous rocks. They are usually dark and hard. Due to their similarity in hardness and color, they can be difficult for some to differentiate from the pyroxenes. They also have a comparable cut. Their chemistry allows for a range of compositions. The various amphibole mineral groups are identified by their chemical compositions and crystal structures. Amphibole asbestos comprises chrysotile and the five asbestos types amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. Each variety of asbestos has its own distinct properties. The most hazardous type of asbestos, crocidolite, is composed of sharp fibers that are simple to inhale into the lung. Anthophyllite is yellowish to brown in color and is composed of iron and magnesium. It was previously used in products like cement and insulation materials. Amphibole minerals are hard to analyze because they have complex chemical structures and a variety of substitutions. A thorough analysis of composition of amphibole minerals requires special methods. The most common methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods only give approximate identifications. These methods, for instance can't distinguish between magnesio hornblende and magnesio hastingsite. Additionally, these techniques do not distinguish between ferro-hornblende as well as pargasite.
