The Dangers of Exposure to Asbestos Before it was banned asbestos was still used in a variety of commercial products. Research shows 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 won't be able to taste or smell it. It is only visible in the event that asbestos-containing products are drilled, chipped or broken. Chrysotile At its height, chrysotile comprised up 99% of the asbestos produced. It was used by many industries which included construction insulation, fireproofing, and construction. If workers are exposed to asbestos, they are likely to develop mesothelioma as well as other asbestos-related illnesses. Since the 1960s, when mesothelioma became an issue asbestos use has decreased significantly. It is still present in many of the products we use today. Chrysotile is safe to use provided you have a comprehensive safety and handling program in place. Personnel handling chrysotile aren't exposed to an undue amount of risk based on the current controlled exposure levels. Lung cancer, lung fibrosis and mesothelioma have all been found to be strongly linked to breathing in airborne respirable fibres. This has been proven in terms of intensity (dose) as well as duration of exposure. One study that studied an industrial facility that used almost exclusively chrysotile in the production of friction materials compared mortality rates at this factory with national mortality rates. The study concluded that, after 40 years of processing low levels of chrysotile, there was no significant increase in mortality at this factory. In contrast to other forms of asbestos, chrysotile fibers tend to be smaller. They can penetrate the lungs and then enter the bloodstream. This makes them more likely to cause health effects than fibres with longer lengths. It is extremely difficult for chrysotile fibrous to be a threat to the air or pose any health risk when mixed with cement. Fibre cement products are extensively used in a variety of locations around the world including hospitals and schools. Research has revealed that amphibole asbestos like amosite or crocidolite is less likely than chrysotile in causing diseases. These amphibole varieties are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile is mixed in with cement, it forms a strong, flexible construction product that can withstand the most extreme conditions in the weather and other environmental dangers. It is also easy to clean up after use. Professionals can safely remove asbestos fibres once they have been removed. Amosite Asbestos is one of the groups of fibrous silicates that are found in certain types 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 fine to wide. They can also be curled or straight. These fibers are found in nature as individual fibrils or as bundles with splaying ends referred to as fibril matrix. Asbestos is also found in powder form (talc) or mixed with other minerals to form vermiculite or talcum powder. They are used extensively as consumer products, like baby powder, cosmetics, and even face powder. The largest asbestos use was during the early two-thirds of the 20th century, when it was used in insulation, shipbuilding, 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 contaminated vermiculite. Exposures varied by industry, time period and geographical location. The majority of asbestos-related exposures in the workplace were due to inhalation. However, some workers were also exposed through contact with skin or by eating food contaminated with asbestos. Asbestos is currently only found in the air due to the natural weathering of mined minerals and the degrading of contaminated materials like insulation, car brakes, clutches as well as ceiling and floor tiles. It is becoming clear that non-commercial amphibole fibres may also be carcinogenic. These fibers aren't tightly weaved like the fibrils in amphibole and serpentine they are loose as well as flexible and needle-like. These fibers are found in the cliffs and mountains in a variety of countries. Asbestos can be absorbed into the environment in many ways, including in the form of airborne particles. It can also be released into water or soil. This is caused by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination in surface and ground water is mostly caused by natural weathering. However it is also caused anthropogenically, such as through milling and mining of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated dumping material in landfills (ATSDR 2001). Inhalation exposure to airborne asbestos fibres is the most common reason for illness among those exposed to asbestos at work. Crocidolite Inhalation exposure to asbestos is the most frequent method by which people are exposed to the harmful fibres that can then be inhaled and cause serious health problems. Mesothelioma, asbestosis, and other diseases are all caused by asbestos fibres. Exposure to asbestos fibres can occur in different ways, including contact with contaminated clothes or building materials. The dangers of this kind of exposure are heightened when crocidolite (the asbestos that is blue, is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe in and can get deeper into lung tissue. It has been associated with a higher number of mesothelioma related cases than any other form of asbestos. The six main types of asbestos are chrysotile, amosite and tremolite. They are epoxiemite, tremol anthophyllite, and actinolite. The most well-known asbestos types are chrysotile and epoxiemite, which together make up the majority of commercial asbestos used. The other four types haven't been as popularly used, but they may still be found in older buildings. They are less hazardous than amosite and chrysotile, however they could be a risk when combined with other asbestos minerals, or when mined close to other naturally occurring mineral deposits, like vermiculite or talc. Several studies have found an connection between asbestos exposure and stomach cancer. The evidence isn't unanimous. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% 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 those working in chrysotile mines and mills. IARC, the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All asbestos types can cause mesothelioma, but the risk is different based on how much exposure is taken, what type of asbestos is involved and the length of time that exposure lasts. The IARC has recommended that abstaining from all asbestos forms is the best option since this is the safest option for people. If someone has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma or any other respiratory illnesses it is recommended that they seek advice from their physician or NHS 111. Amphibole Amphibole is a class of minerals that form long prism or needle-like crystals. They are a type of inosilicate mineral made up of double chains of SiO4 molecules. They usually have a monoclinic structure in their crystals however, some have 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 by tetrahedron rings made of six. The tetrahedrons are separated from each other by strips of octahedral sites. Amphibole minerals can be found in metamorphic and igneous rocks. They are typically dark-colored and tough. Due to their similarity of hardness and color, they can be difficult for some people to differentiate from Pyroxenes. They also have a comparable cleavage. However their chemistry permits many different compositions. The chemical compositions and crystal structures of the different mineral groups found in amphibole may be used to determine their composition. The five asbestos types belonging to the amphibole family are amosite, anthophyllite as well as crocidolite and actinolite. Each type of asbestos comes with its own unique properties. upland asbestos attorney is considered to be the most hazardous asbestos type. It is composed of sharp fibers which are easily inhaled into the lungs. Anthophyllite is yellowish to brown in color and is made up of magnesium and iron. This type of stone was once used in products like cement and insulation materials. Amphiboles are difficult to analyze due to their complex chemical structure and numerous substitutions. A thorough analysis of the composition of amphibole mineral requires specialized methods. The most commonly used methods for identifying amphiboles are EDS, WDS, and XRD. However, these methods only give approximate identifications. These techniques, for example cannot differentiate between magnesio hornblende and magnesio hastingsite. These techniques also don't distinguish between ferro-hornblende and.
