The Dangers of Exposure to Asbestos Asbestos was used in a variety of commercial products before it was banned. Studies have shown that exposure to asbestos can cause cancer and other health issues. You can't tell if something is asbestos-containing by looking at it, and you can't smell or taste it. It can only be found when asbestos-containing materials are chipped, drilled or broken. Chrysotile At its peak, chrysotile accounted for 90% of the asbestos made. It was employed in many industries, including construction insulation, fireproofing, and construction. If workers are exposed to asbestos, they are likely to develop mesothelioma and other asbestos-related diseases. Fortunately, the use this harmful mineral has diminished drastically since mesothelioma awareness started to increase in the 1960's. It is still present in many products we use today. Chrysotile can be safely used in the event that a thorough safety and handling plan is put into place. People who handle chrysotile do not exposed to an unreasonable amount of risk at the present limit of exposure. The inhalation of airborne fibres is strongly linked to lung cancer and lung fibrosis. This has been proven for both intensity (dose) and time of exposure. In one study, mortality rates were compared among a factory which used largely chrysotile in the manufacture of friction materials and national death rates. It was concluded that for 40 years of preparing asbestos chrysotile at low levels of exposure, there was no significant additional mortality in this factory. Chrysotile fibres are usually shorter than other forms of asbestos. They can penetrate the lungs and enter the bloodstream. They are more likely to cause health problems over longer fibres. It is extremely difficult for chrysotile fibres to be in the air or pose a health risk when mixed with cement. Fibre cement products are extensively used throughout the world particularly in buildings like hospitals and schools. Research has shown that chrysotile is less likely to cause illness than amphibole asbestos like crocidolite and amosite. These amphibole types have been the primary source of mesothelioma, as well as other asbestos-related diseases. When chrysotile mixes with cement, it creates a tough, flexible building product that can withstand harsh weather conditions and other environmental hazards. It is also easy to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed. Amosite Asbestos is a category of silicate fibrous minerals that naturally occur in certain types of rock formations. It is classified into six groups: amphibole (serpentine), Tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are made up of long, thin fibers that vary in length from fine to wide. They can be curled or straight. They are present in nature as individual fibrils or as bundles that have splaying ends, referred to as fibril matrix. Asbestos minerals can be found in the form of a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder that are widely used in consumer products like baby powder cosmetics, face powder and other. Asbestos was extensively used in the early two-thirds of the 20th century for shipbuilding as well as insulation, fireproofing and various other construction materials. The majority of asbestos-containing exposures to the workplace were in the air, but some workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied according to the industry, time frame and geographic location. The majority of asbestos exposures that workers were exposed to was because of inhalation, but some workers were also exposed through contact with skin or by eating food contaminated with asbestos. Asbestos can be found in the natural environment due to natural weathering and the degradation of contaminated products like ceiling and floor tiles cars, brakes and clutches, and insulation. There is evidence emerging that amphibole fibres from non-commercial sources could also be carcinogenic. These fibres are not tightly knit like the fibrils found in amphibole and serpentine, but are instead loose elastic, flexible, and needle-like. These fibers can be found in the mountains and cliffs in a variety of countries. Asbestos is absorbed into the environment mostly as airborne particles, but it can also be absorbed into soil and water. This can be triggered 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 in surface and ground waters is primarily due to natural weathering. However it can also be caused by anthropogeny, such as through the mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated dumping materials in landfills (ATSDR 2001). The inhalation of asbestos fibres remains the main cause of illness among people exposed to it occupationally. Crocidolite Exposure to asbestos through inhalation is the most common way people are exposed to the dangerous fibres, which can then enter the lungs and cause serious health issues. These include mesothelioma and asbestosis. The exposure to asbestos can happen in other ways, too, for example, contact with contaminated clothing or construction materials. This kind of exposure is particularly dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are thinner and more fragile which makes them more difficult to breathe in. They can also get deeper within lung tissues. It has been associated with a higher number of mesothelioma-related cases than any other form of asbestos. The six major types of asbestos are chrysotile, amosite as well as epoxiemite. Tremolite is anthophyllite and actinolite. Amosite and chrysotile are the most frequently used types of asbestos. They comprise 95% of the commercial asbestos in use. The other four types of asbestos haven't been as extensively used however, they could be present in older buildings. They are less hazardous than amosite or chrysotile however they could still pose a threat when mixed with other minerals or when mined close to other mineral deposits such as talc and vermiculite. Numerous studies have proven the connection between stomach cancer and asbestos exposure. The evidence isn't unanimous. Some researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% 95% confidence interval: 0.7-3.6) for all workers exposed to asbestos, while others have reported an SMR of 1.24 (95 percent CI: 0.76-2.5) for those who work in chrysotile mines and mills. IARC, the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All types of asbestos can cause mesothelioma as well as other health problems, but the risks differ based on the amount of exposure people are exposed to, the kind of asbestos involved and the duration of their exposure, and the manner in which it is breathed in or consumed. The IARC has recommended that avoid all forms of asbestos should be the top priority since this is the most secure option for people. If you've been exposed to asbestos and are suffering from a respiratory illness or mesothelioma condition, then you should consult your GP or NHS111. Amphibole Amphiboles are groups of minerals that can create prism-like or needle-like crystals. canton asbestos lawyer are a type of inosilicate mineral made up of double chains of SiO4 molecules. They are a monoclinic system of crystals, but some exhibit 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 in a series of six tetrahedrons. The tetrahedrons are separated by strips of octahedral sites. Amphibole minerals are common in metamorphic and igneous rocks. They are usually dark-colored and are hard. Due to their similarity in hardness and color, they may be difficult for some people to distinguish from the pyroxenes. They also share a corresponding pattern of cleavage. Their chemistry allows a wide range of compositions. The various mineral groups within amphibole are identified by their chemical compositions and crystal structures. Amphibole asbestos consists of chrysotile, and the five asbestos types: amosite, anthophyllite (crocidolite) amosite (actinolite), and amosite. While the most commonly used form of asbestos is chrysotile each type has its own unique characteristics. The most dangerous type of asbestos, crocidolite, is composed of sharp fibers that are easy to inhale into the lungs. Anthophyllite is brown to yellowish in color and is composed of magnesium and iron. The variety was used previously in cement and insulation materials. Amphibole minerals are difficult to analyze due to their a complicated chemical structure and a variety of substitutions. Therefore, a detailed analysis of their composition requires special techniques. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. These methods are only able to provide approximate identifications. For instance, these methods are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. These techniques also cannot distinguish between ferro-hornblende as well as pargasite.
