The Dangers of Exposure to Asbestos
Asbestos was found in thousands of commercial products prior to when it was banned. According research, exposure to asbestos can cause cancer as well as other health problems.
You can’t tell if something includes asbestos simply by looking at it and you are unable to smell or taste it. Asbestos can only be identified when the substances that contain it are broken or drilled.
Chrysotile
At the height of its use, chrysotile made up 99% of the asbestos production. It was utilized in a variety of industries, including construction insulation, fireproofing, and insulation. However, if workers were exposed to this toxic substance, they could develop mesothelioma or other asbestos litigation related diseases. Since the 1960s, when mesothelioma first became a problem asbestos use has declined significantly. However, trace amounts of it are still present in the products we use today.
Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. It has been proven that at the present exposure levels, there isn’t an danger to those handling it. Lung fibrosis, lung cancer and mesothelioma have been strongly linked to breathing in airborne respirable fibres. This has been confirmed for both the intensity (dose) and duration of exposure.
One study that examined a facility that used nearly exclusively chrysotile to manufacture friction materials compared mortality rates in this factory with national death rates. The study found that after 40 years of manufacturing low levels of chrysotile there was no significant increase in mortality rates in this factory.
Chrysotile fibres are usually shorter than other types of asbestos. They are able to penetrate the lungs, and then pass through the bloodstream. This makes them much more prone to causing health effects than fibrils with a longer length.
It is extremely difficult for chrysotile fibres to be inhaled or to pose a health risk when mixed with cement. Fibre cement products are extensively used across the globe, especially in buildings such as schools and hospitals.
Research has shown that amphibole asbestos, like amosite or crocidolite is less likely than chrysotile in causing diseases. These amphibole types are the main cause of mesothelioma, and other asbestos-related diseases. When chrysotile is mixed in with cement, it forms a tough, flexible building product that can withstand the most extreme weather conditions and other environmental hazards. It is also easy to clean after use. Asbestos attorney fibers can be easily removed by a professional and safely disposed of.
Amosite
Asbestos refers to a group of silicate mineral fibrous that naturally occur in certain types of rock formations. It is comprised of six general groups: serpentine, amphibole, tremolite, anthophyllite and crocidolite (IARC, 1973).
Asbestos minerals consist of thin, long fibers that vary in length from extremely thin to broad and straight to curled. These fibers are found in nature in the form of individual fibrils or bundles with splaying ends called a fibril matrix. Asbestos minerals can also be found as a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite which are widely used in consumer products, such as baby powder cosmetics, face powder, and baby powder.
The heaviest use of asbestos was in the first two-thirds of twentieth century where it was used in insulation, shipbuilding, fireproofing and other construction materials. The majority of occupational exposures to asbestos fibres were in the air, but some workers also were exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied according to industry, time, and geographic location.
Most of the asbestos-related exposures in the workplace were due to inhalation, but certain workers were exposed by skin contact or through eating contaminated food. Asbestos can be found in the environment due to natural weathering and the degradation of contaminated products like ceiling and floor tiles cars, brakes and clutches as well as insulation.
There is evidence to suggest that amphibole fibres from non-commercial sources could also be carcinogenic. These are the fibres that are not the tightly interwoven fibrils that are found in the amphibole or serpentine minerals but instead are flexible, loose and needle-like. These fibers are found in the mountains and cliffs from a variety of countries.
Asbestos gets into the environment primarily as airborne particles, but it can also leach into water and soil. This can be caused by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is typically a result of natural weathering, however it has also been caused by human activities such as milling and mining demolition and dispersal of asbestos-containing materials, and the removal of contaminated soils for disposal in landfills (ATSDR, 2001). The inhalation of asbestos fibres remains the main cause of illness among people exposed to asbestos in the workplace.
Crocidolite
Inhalation exposure is the most frequent method of exposure to asbestos fibres. The fibres can penetrate the lungs and cause serious health problems. This includes asbestosis and mesothelioma. The exposure to asbestos fibres could be triggered in other ways, such as contact with contaminated clothes or building materials. The risks of exposure are heightened when crocidolite, a blue form of asbestos, is involved. Crocidolite is smaller and more fragile fibers that are easy to breathe in and may lodge deeper in lung tissue. It has been linked to a larger number of mesothelioma cases than any other type of asbestos.
The six major types of asbestos are chrysotile amosite as well as epoxiemite. Tremolite is anthophyllite, asbestos Attorney and actinolite. Chrysotile and amosite are among the most frequently used types of asbestos and account for 95% of the asbestos used in commercial construction. The other four types haven’t been as popularly used but they can be present in older buildings. They are less harmful 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 talc or vermiculite.
Numerous studies have revealed an connection between asbestos exposure and stomach cancer. The evidence isn’t conclusive. Some researchers have cited an 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% confidence interval: 0.76-2.5), for workers in chrysotile mills and mines.
The International Agency for Research on Cancer (IARC) has classed all asbestos types as carcinogenic. All kinds of asbestos can cause mesothelioma or other health issues, but the risks are different based on the amount of exposure people are exposed to, the kind of asbestos used as well as the length of their exposure and the manner in which it is inhaled or consumed. IARC has declared that the best option for individuals is to avoid all types of asbestos. However, if a person has been exposed to asbestos in the past and suffer from an illness such as mesothelioma and other respiratory ailments, they should seek guidance from their physician or NHS 111.
Amphibole
Amphiboles are groups of minerals that may form prism-like and needle-like crystals. They are a type inosilicate mineral composed of double chains of SiO4 molecules. 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 are made up of (Si,Al)O4 tetrahedrons that are linked in rings of six. Tetrahedrons are distinguished from each other by octahedral sites in strips.
Amphibole minerals can be found in metamorphic and igneous rocks. They are usually dark-colored and hard. Due to their similarity in strength and colour, they can be difficult for some to distinguish from the pyroxenes. They also have a similar Cleavage. Their chemistry permits a wide variety of compositions. The chemical compositions and crystal structures of the various mineral groups in amphibole could be used to identify them.
Amphibole asbestos consists of chrysotile, and the five types of asbestos amosite anthophyllite (crocidolite) amosite (actinolite), and amosite. The most widely used asbestos type is chrysotile each type has its own distinct characteristics. The most harmful type of asbestos, crocidolite, is made up of sharp fibers that are simple to breathe into the lungs. Anthophyllite ranges from brown to yellowish in color and is made up of magnesium and iron. This variety was once used in cement and insulation materials.
Amphibole minerals are challenging to analyze because they have an intricate chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires special techniques. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. These methods are only able to provide approximate identifications. For instance, these methods cannot distinguish between magnesiohastingsite and magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro hornblende and pargasite.
