The Dangers of Exposure to AsbestosBefore it was banned, asbestos was widely used in commercial products. Studies have shown that exposure to asbestos can cause cancer and other health problems.It is difficult to tell if something has asbestos just by looking at it, and you can’t taste or smell it. Asbestos is only detected when the substances that contain it are broken, drilled, or chipped.ChrysotileAt its height, chrysotile provided for 99% of the asbestos created. It was used by many industries which included construction insulation, fireproofing, and construction. If workers were exposed to this toxic substance, they could develop mesothelioma or other asbestos related diseases. Since the 1960s, when mesothelioma first became a problem the use of asbestos has declined significantly. It is still present in a variety of products we use in the present.Chrysotile is safe to use provided you have a comprehensive safety and handling plan in place. It has been discovered that, at the present controlled exposure levels, there is no undue risk to the workers working with the substance. The inhalation of airborne particles has been strongly associated with lung fibrosis and lung cancer. This has been confirmed both for intensity (dose) as well as duration of exposure.A study that looked at an industrial facility that used almost exclusively chrysotile to manufacture 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 rise in mortality rates at this facility.Chrysotile fibres are usually shorter than other forms of asbestos. 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 fibers to be in the air or pose a health risk when mixed with cement. The fibre cement products are extensively used across the globe, especially in buildings such as schools and hospitals.Research has revealed that chrysotile is less prone to cause disease than amphibole asbestos like crocidolite and amosite. These amphibole varieties are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile and cement are mixed with cement, a tough, flexible product is created that is able to withstand extreme environmental hazards and weather conditions. It is also easy to clean after use. Professionals can safely get rid of asbestos fibres after they have been removed.AmositeAsbestos is one of the groups of fibrous silicates that are found in a variety of rock formations. It is divided into six groups: amphibole (serpentine), tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.Asbestos minerals consist of long, thin fibers that vary in length from extremely fine to broad and straight to curled. These fibers are found in nature in bundles or individual fibrils. Asbestos minerals are also found in the form of a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder, which have been widely used in consumer products such as baby powder cosmetics, face powder and other.The most extensive use of asbestos occurred in the first two-thirds of 20th century in the period when it was employed in insulation, shipbuilding, fireproofing, and other construction materials. Most occupational exposures were asbestos fibres that were borne in the air, but some workers were exposed to vermiculite or talc that was contaminated, and to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied by industry, time period, and geographic location.The majority of asbestos-related exposures in the workplace were because of inhalation, but some workers were also exposed via skin contact or by eating food contaminated with asbestos. Asbestos can only be found in the natural environment due to natural weathering and degradation of contaminated products, such as ceiling and floor tiles as well as car brakes and clutches as well as insulation.There is growing evidence that non-commercial amphibole fibers could also be carcinogenic. They are not tightly woven like the fibrils found in amphibole or serpentine, they are loose, flexible, and needle-like. These fibers can be found in the cliffs and mountains of several countries.Asbestos is absorbed into the environment mostly in the form of airborne particles, however it can also be absorbed into soil and water. This can be due to both natural (weathering of asbestos-bearing rocks) and anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is largely associated with natural weathering, however it has also been triggered by anthropogenic activities like mining and milling demolition and dispersal of asbestos-containing materials and the disposal of contaminated dumping soil in landfills (ATSDR, 2001). Asbestos fibres that are emitted from the air are the primary cause of illness among people exposed to asbestos in their work.CrocidoliteInhalation exposure is the most frequent method of exposure to asbestos fibres. These fibres can infiltrate the lung which can cause serious health issues. Mesothelioma, asbestosis, and other diseases can be caused by asbestos fibres. Exposure to fibres can occur in other ways, too, for example, contact with contaminated clothing or materials. The dangers of exposure are heightened when crocidolite which is the asbestos that is blue is involved. Crocidolite is smaller and more fragile fibers that are more easy to inhale and can lodge deeper in lung tissue. It has been linked to more mesothelioma-related cases than other types of asbestos.The six main types of asbestos are chrysotile, amosite, epoxiemite, tremolite anthophyllite, and actinolite. The most well-known forms of asbestos are epoxiemite and chrysotile which together make up the majority of commercial asbestos employed. The other four types of asbestos haven’t been as widely used however, they could be present in older buildings. They are less dangerous than chrysotile and amosite, but they could be a risk when combined with other asbestos minerals or mined close to other naturally occurring mineral deposits, like vermiculite or talc.Many studies have discovered an connection between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. However there is no conclusive evidence. Some researchers have cited a SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, while others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those working in mines and chrysotile mills.The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma, however the risks differ based on the amount of exposure, what type of asbestos is involved and how long exposure lasts. The IARC has recommended that avoiding all forms of asbestos should be the top priority since this is the safest option for individuals. If you’ve been exposed to asbestos and are suffering from a respiratory condition or mesothelioma, you should talk to your doctor or NHS111.AmphiboleAmphiboles comprise a variety of minerals that form prism-like or needle-like crystals. They are an inosilicate minerals made of double chains of SiO4 molecules. They have a monoclinic arrangement of crystals, however some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. ann arbor asbestos lawsuit consist of (Si,Al)O4 Tetrahedrons, which are connected in rings of six. The tetrahedrons can be separated by strips of octahedral sites.Amphibole minerals are common in igneous and metamorphic rocks. They are usually dark and hard. Due to their similarity in hardness and colour, they can be difficult for some people to differentiate from Pyroxenes. They also have a similar cleavage. However, their chemistry allows for many different compositions. The chemical compositions and crystal structure of the various mineral groups in amphibole can be used to determine their composition.Amphibole asbestos consists of chrysotile, and the five asbestos types amosite, anthophyllite (crocidolite) amosite (actinolite) and amosite. While the most frequently used form of asbestos is chrysotile; each has distinct characteristics. The most harmful type of asbestos, crocidolite, is made up of sharp fibers that are easy to breathe into the lung. Anthophyllite comes in a brownish-to yellowish hue and is made primarily of magnesium and iron. This type of stone was once used in products like cement and insulation materials.Amphiboles can be difficult to study due to their complicated chemical structure and numerous substitutions. A thorough analysis of composition of amphibole minerals requires specialized techniques. The most common methods of identifying amphiboles include EDS, WDS, and XRD. However, these methods only provide approximate identifications. For instance, they can’t distinguish between magnesio hastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro-hornblende and pargasite.
