The Dangers of Exposure to Asbestos
Before it was banned asbestos was widely used in commercial products. According to research, exposure to asbestos can cause cancer, as well as other health problems.
It is difficult to tell if something has asbestos just by looking at it, and you are unable to smell or taste it. Asbestos can only be identified when the materials that contain it are broken, drilled, or chipped.
Chrysotile
At its height, chrysotile comprised up 99% of asbestos production. It was utilized in a variety of industries like construction insulation, fireproofing, and insulation. Unfortunately, if workers were exposed to this harmful material, they may develop mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma first became a major concern the use of asbestos case has been reduced significantly. It is still present in a variety of products we use in the present.
Chrysotile can be used safely in the event that a thorough safety and handling plan is put into place. Chrysotile handling workers aren't exposed to an undue amount of risk at the present limit of exposure. Lung cancer, lung fibrosis and mesothelioma were all linked to breathing in airborne respirable fibres. This has been proven for both intensity (dose) and duration of exposure.
One study that studied a facility that used nearly all chrysotile as its friction materials, compared mortality rates in this facility with national death rates. It was found that, over the course of 40 years, processing chrysotile asbestos at low levels of exposure There was no significant additional mortality in this factory.
Unlike some other forms of asbestos, chrysotile fibres tend to be shorter. They can pass through the lungs and enter the bloodstream. This makes them more likely to cause ill-health consequences than longer fibres.
It is very difficult for chrysotile fibres be a threat to the air or pose any health risk when mixed with cement. Fibre cement products are widely used in various parts of the world including hospitals and schools.
Research has proven that amphibole asbestos like crocidolite or amosite is less likely to cause disease. These amphibole varieties are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile gets mixed with cement, it forms a strong, flexible construction product that can withstand the most extreme weather conditions and other environmental hazards. It is also easy to clean up after use. Asbestos fibres can easily be removed by a professional and removed.
Amosite
Asbestos is a term used to describe a class of silicate mineral fibrous which are found naturally in a variety of types of rock formations. It consists of six general groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC, 1973).
Asbestos minerals are composed of thin, long fibers that vary in length, ranging from very fine to wide and straight to curled. They are found in nature as individual fibrils or as bundles with splaying edges called a fibril matrix. Asbestos minerals are also found as a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite which are widely used in consumer products like baby powder cosmetics, face powder, and baby powder.
The most extensive asbestos use was during the first two-thirds period of the 20th 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, but certain workers were also exposed to asbestos-bearing rock fragments and contaminated vermiculite. Exposures varied according to industry, time and geographic location.
Exposure to asbestos in the workplace is usually because of inhalation. However there have been instances of workers being exposed by contact with their skin or eating food that is contaminated. Asbestos is found in the natural environment due to natural weathering and the degradation of contaminated products like ceiling and floor tiles automobile brakes and clutches, and insulation.
It is becoming evident that non-commercial amphibole fibers could also be carcinogenic. These are fibres are not the tightly interwoven fibrils that are found in the amphibole and serpentine minerals, but instead are loose, flexible and needle-like. These fibers are found in the cliffs and mountains in a variety of countries.
Asbestos enters the environment mainly in the form of airborne particles, however it can also be absorbed into soil and water. This is a result of both natural (weathering and erosion of asbestos-bearing rocks) and the anthropogenic (disintegration and disposal of asbestos-containing materials in landfill sites) sources. asbestos law (http://envtox.snu.ac.kr/) contamination in surface and ground waters is primarily due to natural weathering. However it can also be caused by anthropogeny, Asbestos Law such as by the milling and mining of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Inhalation exposure to asbestos fibers is the primary reason for illness among those exposed to it occupationally.
Crocidolite
Inhalation exposure to asbestos is the most popular way people are exposed harmful fibres. They can then enter the lungs and cause serious health problems. These include asbestosis and mesothelioma. Exposure to asbestos fibres can occur in other ways as well including contact with contaminated clothing or construction materials. The dangers of this kind of exposure are higher when crocidolite, the asbestos' blue form, is involved. Crocidolite is smaller and more fragile fibers, which are easier to breathe in and can get deeper in lung tissue. It has been linked to more mesothelioma-related cases than other types of asbestos.
The six major types of asbestos are chrysotile amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. Chrysotile and amosite are among the most commonly used forms of asbestos and make up 95% of asbestos used in commercial construction. The other four asbestos types aren't as prevalent, but could still be found in older structures. They are not as hazardous as chrysotile and amosite, but they may pose a danger when combined with other asbestos minerals, or when mined in close proximity to other mineral deposits, such as vermiculite or talc.
Numerous studies have proven that there is a link between stomach cancer and asbestos exposure. The evidence isn't unanimous. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% of the time CI: 0.7-3.6) for all workers exposed to asbestos as well as an SMR of 1.24 (95 percent 95% CI: 0.76-2.5) for those who work in chrysotile mines and mills.
The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All kinds of asbestos may cause mesothelioma as well as other health issues, but the risks are different based on the amount of exposure individuals are exposed to, the type of asbestos used, the duration of their exposure and the way in the way that it is breathed in or ingested. IARC has declared that the best option for people is to avoid all types of asbestos. If you've been exposed in the past to asbestos and are suffering from a respiratory condition or mesothelioma, you should see your physician or NHS111.
Amphibole
Amphiboles are a grouping of minerals which can form needle-like or prism-like crystals. They are a type of silicate mineral that is composed of double chains of SiO4 molecules. They usually have a monoclinic crystal system, although some have an orthorhombic structure. 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 joined in rings of six. Tetrahedrons are distinguished from each other by octahedral sites in strips.
Amphibole minerals are found in metamorphic and igneous rocks. They are usually dark-colored and hard. Due to their similarity in strength and color, they may be difficult for some to differentiate from the pyroxenes. They also share a corresponding Cleavage. However, asbestos law their chemistry allows for an array of compositions. The chemical compositions and crystal structure of the different mineral groups in amphibole could be used to determine their composition.
Amphibole asbestos includes chrysotile and the five types of asbestos amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. Each variety of asbestos has its own distinctive properties. The most dangerous form of asbestos, crocidolite, is made up of sharp fibers that are simple to inhale into the lungs. Anthophyllite is yellowish to brown in color and is made up of magnesium and iron. The variety was used previously in products like cement and insulation materials.
Amphiboles are difficult to analyse due to their complicated chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires special techniques. The most common methods for identifying amphiboles is EDS, WDS, and XRD. These methods can only provide approximate identifications. These techniques, for example, cannot distinguish between magnesio-hornblende and hastingsite. Moreover, these techniques do not distinguish between ferro hornblende and pargasite.
