The Dangers of Exposure to Asbestos Before it was banned asbestos was used in a myriad of commercial products. According to research, exposure to asbestos can cause cancer and a host of other health problems. It is impossible to tell just by looking at a thing if it contains asbestos. You cannot taste or smell it. Asbestos is only detectable when the substances that contain it are broken, drilled, or chipped. Chrysotile At its peak, chrysotile accounted for the majority of the asbestos production. It was utilized in a variety of industries such as construction insulation, fireproofing, and construction. If workers were exposed for long periods to this toxic material, they could develop mesothelioma as well as other asbestos related diseases. Thankfully, the use this toxic mineral has decreased drastically since mesothelioma awareness started to increase in the 1960's. It is still found in a variety of products we use in the present. Chrysotile is safe to use in the event that a thorough safety and handling plan is put into place. It has been proven that at the present exposure levels, there isn't an unneeded risk to the people working with it. Lung cancer, lung fibrosis and mesothelioma are all linked to breathing airborne respirable fibres. This has been proven both for intensity (dose) as well as duration of exposure. In one study, mortality rates were compared between a manufacturing facility that used a large proportion of chlorosotile to make friction materials and the national death rate. The study revealed that after 40 years of converting 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 can penetrate the lungs and enter the bloodstream. This makes them much more likely to cause health effects than longer fibres. It is very difficult for chrysotile fibres to be inhaled or to pose a health risk when mixed with cement. The fibre cement products are extensively used all over the world particularly in buildings like hospitals and schools. Research has shown that amphibole asbestos like amosite or crocidolite is not as likely to cause disease. These amphibole types are the main cause of mesothelioma and other asbestos-related diseases. When chrysotile is combined with cement, it forms a tough, flexible building product that can withstand the most extreme conditions in the weather and other environmental dangers. It is also very easy to clean up after use. Professionals can safely eliminate asbestos fibres when they have been removed. Amosite Asbestos is a class of fibrous silicates that are found in a variety of rock formations. It is divided into six groups: amphibole (serpentine) and Tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are made up of long, thin fibers that range in length from fine to broad. They can also be curled or straight. They are found in nature in bundles or as individual fibrils. Asbestos minerals can also be found in powder form (talc) or mixed with other minerals and sold as talcum powder and vermiculite and are used in consumer products such as baby powder cosmetics, face powder and baby powder. The greatest use of asbestos occurred in the first two-thirds of the twentieth century when it was utilized in insulation, shipbuilding, fireproofing, and other construction materials. The majority of occupational exposures to asbestos fibres were in the air, however certain workers were also exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied by the industry, time frame, and geographic location. Asbestos exposure at work is mostly due to inhalation. However there are workers who have been exposed by contact with their skin or through eating foods contaminated with asbestos. Asbestos is currently only found in the air due to natural weathering of mined ores and deterioration of contaminated products such as insulation, car brakes, clutches, and floor and ceiling tiles. There is evidence emerging that amphibole fibres from non-commercial sources could also be carcinogenic. pittsburgh asbestos law firm are fibres that are not the tightly woven fibrils of the serpentine and amphibole minerals, but instead are flexible, loose and needle-like. They can be found in cliffs, mountains and sandstones from a variety of nations. Asbestos may enter the environment in a variety of ways, including through airborne particles. It can also leach out into water or soil. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination of surface and ground waters is primarily caused by natural weathering. However it can also be caused anthropogenically, such as by the milling and mining of asbestos-containing materials demolition and dispersal and the removal of contaminated dumping material in landfills (ATSDR 2001). Exposure to asbestos-containing airborne fibres is the most common cause of illness for people who are exposed to asbestos on a daily basis. Crocidolite Exposure to asbestos through inhalation is the most popular way people are exposed to the harmful fibres, which could then get into the lungs and cause serious health problems. These include mesothelioma and asbestosis. Exposure to asbestos fibres can be triggered in other ways, including contact with contaminated clothing or building materials. The dangers of this kind of exposure are higher when crocidolite, the asbestos' blue form, is involved. Crocidolite fibers are less dense and more fragile and therefore easier to inhale. They can also get deeper inside lung tissue. It has been linked to a greater number of mesothelioma related cases than any other type of asbestos. The six main types of asbestos are chrysotile amosite, epoxiemite, tremolite anthophyllite and actinolite. Amosite and chrysotile are two of the most commonly used forms of asbestos and make up 95% of commercial asbestos in use. The other four asbestos types aren't as prevalent, but could still be found in older structures. They are less hazardous than amosite or chrysotile but still be a risk when mixed with other minerals or when mined near other mineral deposits such as talc and vermiculite. Numerous studies have demonstrated an association between stomach cancer and asbestos exposure. However, the evidence is contradictory. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95 percent 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 who work in chrysotile mines and mills. IARC The IARC, also known as the International Agency for Research on Cancer has classified all kinds of asbestos carcinogenic. All kinds of asbestos may cause mesothelioma and other health issues, but the risks vary according to the amount of exposure that individuals are exposed to, the type of asbestos involved and the duration of their exposure and the manner in the way that it is breathed in or consumed. The IARC has advised that avoid all forms of asbestos should be the highest priority since this is the most secure option for individuals. If you have been exposed in the past to asbestos and suffer from a respiratory illness or mesothelioma, you should talk to your doctor or NHS111. Amphibole Amphiboles are a collection of minerals which can form prism-like or needle-like crystals. They are an inosilicate minerals made 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 consist of (Si,Al)O4 Tetrahedrons which are connected in rings of six. The tetrahedrons are separated one another with octahedral strips. Amphibole minerals are common in igneous and metamorphic rocks. They are typically dark-colored and hard. They are sometimes difficult to distinguish from pyroxenes since they share similar hardness and color. They also have a similar cut. However, their chemistry allows for many different compositions. The chemical compositions and crystal structure of the different mineral groups in amphibole can be used to determine their composition. The five asbestos types in the amphibole family include amosite, anthophyllite and chrysotile, crocidolite, and actinolite. Each type of asbestos has its own distinct properties. Crocidolite is considered to be the most hazardous asbestos kind. It is made up of sharp fibers that can easily be inhaled into the lung. Anthophyllite can range from yellow to brown in color and is composed of magnesium and iron. This variety was used to make cement and insulation materials. Amphiboles are difficult to analyse due to their complex chemical structure and the numerous substitutions. A thorough analysis of the composition of amphibole minerals requires special techniques. The most widely used methods for identifying amphiboles are EDS, WDS, and XRD. These methods are only able to provide approximate identifications. For example, these techniques can't distinguish between magnesio hastingsite and magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro-hornblende or pargasite.
