The Dangers of Exposure to Asbestos Before it was banned asbestos was used in thousands commercial products. Studies have shown that exposure to asbestos can cause cancer and other health problems. It is impossible to determine if a product is asbestos-containing by looking at it, and you are unable to smell or taste it. It can only be found when asbestos-containing materials are chipped, drilled or broken. Chrysotile At its height, chrysotile was responsible for 95% of the asbestos created. It was utilized in a variety of industries including construction insulation, fireproofing, and construction. If workers are exposed to asbestos, they are likely to develop mesothelioma along with other asbestos-related diseases. Thankfully, the use of this toxic mineral has decreased dramatically since mesothelioma awareness began to increase in the 1960's. However, it is still present in trace amounts. are still present in products that we use in the present. Chrysotile is safe to use when you have a thorough safety and handling program in place. It has been discovered that, at the present controlled exposure levels, there isn't an undue risk to the workers who handle it. Lung cancer, lung fibrosis and mesothelioma have been strongly linked to breathing airborne respirable fibres. This has been proven to be true for both intensity (dose) and the duration of exposure. One study that looked into a facility that used nearly exclusively chrysotile in the production of friction materials compared the mortality rates of this factory with national mortality rates. It was found that, for 40 years of preparing asbestos chrysotile at a low level of exposure there was no signifi cant excess mortality in this factory. Contrary to other types of asbestos, chrysotile fibers tend to be shorter. They are able to penetrate the lungs and pass into the bloodstream. They are therefore more likely to cause health issues than longer fibres. 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 schools and hospitals. Research has shown that amphibole asbestos, such as crocidolite or amosite is less likely than chrysotile to cause disease. These amphibole types have been the most common source of mesothelioma, as well as other asbestos-related illnesses. When chrysotile mixes with cement, it forms a strong, flexible building product that can withstand the most extreme weather conditions and other environmental dangers. It is also easy to clean after use. Professionals can safely remove asbestos fibres once they have been removed. Amosite Asbestos is a class of fibrous silicates found in certain types rock formations. It is classified into six groups which include amphibole (serpentine) and the tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are composed of long, thin fibers that range in length from fine to broad. They can also be straight or curled. They are present in nature as individual fibrils, or as bundles that have splaying ends, referred to as a fibril matrix. Asbestos minerals can also be found in powder form (talc) or mixed with other minerals and sold as talcum powder and vermiculite, which have been widely used in consumer products such as baby powder, face powder and cosmetics. glendale asbestos attorneys was widely used during the first two thirds of the 20th century for construction of ships insulation, fireproofing, insulation and other construction materials. The majority of occupational exposures involved asbestos fibres borne by air, but certain workers were exposed to toxic talc or vermiculite and also to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied from industry to industry, era to era, and geographical location. The exposure to asbestos in the workplace is mostly caused by inhalation. However, some workers have been exposed through contact with skin or eating food that is contaminated. Asbestos is only found in the environment due to natural weathering and degradation of contaminated products, such as ceiling and floor tiles as well as car brakes and clutches, and insulation. There is evidence emerging that amphibole fibers that are not commercially available could also be carcinogenic. These fibers aren't tightly knit like the fibrils found in amphibole and serpentine they are loose elastic, flexible, and needle-like. These fibers can be found in mountains, sandstones, and cliffs of many countries. Asbestos is able to enter the environment in many ways, including through airborne particles. It can also be absorbed into water or soil. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing wastes in landfill sites) sources. Asbestos contamination of surface and ground water is largely associated with natural weathering, however it has also been caused by anthropogenic activities such as mining and milling, demolition and dispersal of asbestos-containing materials, and the removal of contaminated dumping soil in landfills (ATSDR, 2001). Inhalation exposure to airborne asbestos fibres remains the main cause of illness in people exposed to it occupationally. Crocidolite Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can infiltrate the lungs and cause serious health issues. These include mesothelioma and asbestosis. Exposure to asbestos fibres can be triggered in other ways, such as contact with contaminated clothing or building materials. The dangers of this kind of exposure are heightened when crocidolite which is the asbestos' blue form is involved. Crocidolite fibers are less dense and more fragile which makes them more difficult to inhale. They can also get deeper inside lung tissues. It has been linked to more mesothelioma cases than other types of asbestos. The six main types of asbestos are chrysotile amosite, epoxiemite, tremolite, anthophyllite and actinolite. Chrysotile and amosite are among the most frequently used types of asbestos and account for 95% of the commercial asbestos currently used. The other four types haven't been as widely utilized but they can be found in older buildings. They are less hazardous than amosite or chrysotile but still be a danger when combined with other minerals or when mined close to other mineral deposits, such as talc and vermiculite. Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. However the evidence is not conclusive. Some researchers have reported an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, whereas others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those working in chrysotile mines and mills. The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All kinds of asbestos may cause mesothelioma and other health problems, but the risks vary according to the amount of exposure individuals are exposed to, the type of asbestos involved and the duration of their exposure and the method by which it is breathed in or ingested. IARC has stated that the best choice for people is to avoid all types of asbestos. However, if someone 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 doctor or NHS 111. Amphibole Amphibole is one of the minerals that form long prisms or needlelike crystals. They are a type of silicate mineral composed of double chains of SiO4 molecules. They have a monoclinic structure of crystals, but some have an orthorhombic structure. 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. The tetrahedrons can be separated by strips of octahedral site. Amphiboles are found in metamorphic and igneous rock. They are usually dark-colored and are hard. Due to their similarity of hardness and color, they can be difficult for some people to distinguish from pyroxenes. They also have a comparable Cleavage. Their chemistry allows for a variety of compositions. The various amphibole mineral groups are identified by their chemical compositions and crystal structures. The five types of asbestos that belong to the amphibole group include amosite, anthophyllite and crocidolite. They also include actinolite. Each type of asbestos has its own distinctive properties. Crocidolite is considered to be the most hazardous asbestos kind. It is made up of sharp fibers that are easily breathed into the lung. Anthophyllite is brown to yellowish in color and is made up of iron and magnesium. This kind of material was used to create cement and insulation materials. Amphiboles are a challenge to analyze because of their complex chemical structure and the numerous substitutions. Therefore, a thorough analysis of their composition requires specialized techniques. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods only provide approximate identifications. For example, these techniques cannot distinguish between magnesiohastingsite and magnesio-hornblende. These techniques also cannot distinguish between ferro-hornblende and pargasite.
