The Dangers of Exposure to AsbestosAsbestos was used in a variety of commercial products prior to when it was banned. According to studies, exposure to asbestos can cause cancer and many other health issues.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 materials containing asbestos are chipped, drilled or broken.ChrysotileAt its peak, chrysotile made up for 99percent of the asbestos that was produced. It was employed in many industries including construction insulation, fireproofing, as well as insulation. If workers are exposed to asbestos, they could develop mesothelioma and other asbestos-related diseases. Thankfully, the use of this toxic mineral has decreased dramatically since mesothelioma awareness began to grow in the 1960's. However, trace amounts remain in the products we use today.Chrysotile is safe to use if you have a comprehensive safety and handling program in place. People who handle chrysotile do not exposed to a significant amount of risk at current controlled exposure levels. Inhaling airborne fibers is strongly linked to lung cancer and lung fibrosis. This has been confirmed in terms of intensity (dose) as and 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. The study revealed that after 40 years of manufacturing low levels of chrysotile there was no significant increase in mortality in this factory.In contrast to other forms of asbestos, chrysotile fibers tend to be smaller. They are able to enter the lungs and pass into the bloodstream. This makes them more prone to causing health effects than fibres with longer lengths.It is extremely difficult for chrysotile fibres be a threat to the air or pose any health risk when mixed with cement. federal way asbestos law firm are used in a variety of locations around the world including hospitals and schools.Research has shown that amphibole asbestos, like amosite or crocidolite is less likely than chrysotile to cause diseases. Amphibole types like these are the primary source of mesothelioma as well as other asbestos-related diseases. When chrysotile gets mixed with cement, it creates an extremely durable and flexible building product that can withstand the most extreme weather conditions and other environmental hazards. It is also very easy to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed.AmositeAsbestos is one of the groups of fibrous silicates found in certain types rock formations. It is classified into six groups: amphibole (serpentine), tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.Asbestos minerals comprise long, thin fibers that range in length from fine to broad. They can also be straight or curled. They are present in nature in the form of individual fibrils or bundles with splaying ends referred to as a fibril matrix. Asbestos minerals are also found in the form of a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite and are used in consumer products like baby powder cosmetics, face powder, and baby powder.Asbestos was heavily used in the first two thirds of the 20th century to construct shipbuilding, insulation, fireproofing, and other construction materials. The majority of asbestos-containing exposures to the workplace occurred in the air, however some workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied from industry to industry, era era, and geographical location.Most of the asbestos-related exposures in the workplace were due to inhalation, but some workers were also exposed by skin contact or through eating contaminated food. Asbestos is found in the environment because of natural weathering and degradation of contaminated products, such as ceiling and floor tiles, car brakes and clutches, as well as insulation.There is growing evidence that amphibole fibres from non-commercial sources could also be carcinogenic. These are fibres 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 the cliffs, mountains and sandstones of a variety of countries.Asbestos is absorbed into the environment mostly in the form of airborne particles, however it can also leach into soil and water. This can be caused by both natural (weathering of asbestos-bearing rock) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of ground and surface water is mostly due to natural weathering, but has also been caused by anthropogenic activities like mining and milling demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated soils for disposal in landfills (ATSDR 2001). Inhalation exposure to airborne asbestos fibres remains the main cause of illness for people exposed to asbestos at work.CrocidoliteExposure to asbestos through inhalation is the most frequent way people are exposed dangerous fibres, which can then be inhaled and cause serious health problems. These include asbestosis and mesothelioma. The exposure to asbestos fibres could also take place in other ways, such as contact with contaminated clothing or building materials. This kind of exposure is particularly dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite is smaller and more fragile fibers that are easy to breathe and can be lodged deeper in lung tissue. It has been linked to more mesothelioma-related cases than other asbestos types.The six primary types are chrysotile as well as amosite. Chrysotile and amosite are the most frequently used types of asbestos, and comprise 95% of the asbestos used in commercial construction. The other four asbestos types are not as widespread, but they can still be present in older structures. They are less hazardous than chrysotile and amosite, but they could pose a threat when combined with other asbestos minerals, or when mined close to other naturally occurring mineral deposits, such as vermiculite or talc.Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. However, the evidence is contradictory. Some researchers have cited a SMR (standardized death ratio) of 1.5 (95 percent 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 or chrysotile mills.IARC The IARC, also known as the International Agency for Research on Cancer, has classified all kinds of asbestos carcinogenic. All types of asbestos can cause mesothelioma or other health issues, but the risks differ based on the amount of exposure that individuals are exposed to, the kind of asbestos used, the duration of their exposure and the manner in the way it is inhaled or ingested. IARC has stated that the best option for people is to stay clear of all forms of asbestos. If you have been exposed to asbestos and suffer from a respiratory disorder or mesothelioma condition, then you should talk to your doctor or NHS111.AmphiboleAmphibole is a class of minerals that form long prisms or needle-like crystals. They are a type inosilicate mineral composed of double chains of molecules of SiO4. They have a monoclinic arrangement of crystals, but some have an orthorhombic shape. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 Tetrahedrons, which are connected in rings of six. The tetrahedrons are separated each other by octahedral sites in strips.Amphiboles are present in both igneous and metamorphic rock. They are usually dark-colored and tough. Because of their similar hardness and color, they may be difficult for some people to distinguish from Pyroxenes. They also share a corresponding cleavage. Their chemistry allows for a range of compositions. The chemical compositions and crystal structure of the various mineral groups in amphibole could be used to identify them.The five types of asbestos belonging to the amphibole family are amosite, anthophyllite and chrysotile, crocidolite, and actinolite. Each type of asbestos has distinct characteristics. The most dangerous form of asbestos, crocidolite, is composed of sharp fibers that are easy to inhale into the lungs. Anthophyllite comes in a brownish-to yellowish color and is composed mostly of iron and magnesium. This variety was used to make cement and insulation materials.Amphibole minerals are hard to analyze due to their an intricate chemical structure and numerous substitutions. A thorough analysis of the composition of amphibole minerals requires special techniques. The most commonly used methods to identify amphiboles are EDS, WDS, and XRD. However, these methods can only give approximate identifications. For instance, these techniques cannot differentiate between magnesio-hastingsite and magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro-hornblende or pargasite.
