The Dangers of Exposure to Asbestos
Before it was banned, asbestos was used in thousands commercial products. Research has shown that exposure to asbestos can cause cancer and other health problems.
It is difficult to tell by looking at something if it is made up of asbestos law. It is also impossible to taste or smell it. Asbestos can only be identified when the substances that contain it are broken, drilled, or chipped.
Chrysotile
At its peak, chrysotile accounted for 95% of the asbestos litigation made. It was widely used in industries including construction, fireproofing, and insulation. However, if workers were exposed to this harmful substance, they could develop mesothelioma or other asbestos related diseases. Fortunately, the use of this dangerous mineral has decreased dramatically since mesothelioma awareness began to grow in the 1960's. However, traces of it are still present in many of the products we use today.
Chrysotile is safe to use if you have a comprehensive safety and handling program in place. Workers handling chrysotile are not exposed to a significant amount of risk at the current controlled exposure levels. Inhaling airborne fibers has been linked with lung fibrosis and lung cancer. This has been confirmed for both intensity (dose) and the duration of exposure.
One study that studied a factory that used almost all chrysotile as its friction materials, compared the mortality rates of this factory with national death rates. It was found that, for 40 years of preparing asbestos chrysotile in low levels of exposure, there was no significant excess mortality in this factory.
Chrysotile fibers are generally shorter than other types of asbestos. They are able to penetrate the lungs and enter the bloodstream. This makes them more likely to cause health effects than fibrils with a longer length.
When chrysotile gets mixed with cement, it is very difficult for the fibres to be airborne and pose any health risk. Fibre cement products are used extensively throughout the world particularly in structures such as schools and hospitals.
Research has revealed that amphibole asbestos, such as crocidolite or amosite is less likely to cause disease. These amphibole types have been the primary cause of mesothelioma and various asbestos-related illnesses. When chrysotile gets mixed with cement, it forms an extremely durable and flexible building product that can withstand harsh weather conditions and other environmental dangers. 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 fibrous silicates found in certain types of rock formations. It is comprised of six general groups: amphibole, serpentine, tremolite, anthophyllite and crocidolite (IARC, 1973).
Asbestos minerals are made up of long, thin fibres that vary in length from very thin to broad and straight to curled. They are present in nature in the form of individual fibrils or bundles that have splaying ends, referred to as a fibril matrix. Asbestos is also found in a powder form (talc), or mixed with other minerals to make talcum powder or vermiculite. These are commonly used as consumer products, including baby powder, cosmetics and face powder.
The most extensive use of asbestos was in the first two-thirds period of the 20th century in the period when it was employed in shipbuilding, insulation, fireproofing and other construction materials. The majority of occupational exposures were asbestos fibres in the air, however certain workers were exposed to vermiculite or talc that was contaminated, and to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied according to industry, time and geographic location.
The majority of asbestos exposures at work were because of inhalation, but certain workers were exposed through skin contact or through eating contaminated food. Asbestos can only be found in the environment because of natural weathering and the degradation of contaminated products, such as ceiling and floor tiles automobile brakes and clutches, and insulation.
It is becoming evident that non-commercial amphibole fibers can also be carcinogenic. These fibres are not tightly weaved like the fibrils in amphibole or serpentine, but are instead loose elastic, flexible, and needle-like. These fibers are found in the mountains and cliffs of several countries.
Asbestos enters the environment mainly as airborne particles, but it can also leach into water and soil. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination of ground and surface water is largely associated with natural weathering, but has also been caused by human activities such as milling and mining demolition and dispersal of asbestos-containing material and the disposal of contaminated soils for [Redirect-302] disposal in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the most significant cause of illness in people who are exposed to it during their occupation.
Crocidolite
Inhalation exposure to asbestos is the most frequent way people are exposed to harmful fibres, which could be absorbed into the lungs and cause serious health issues. These include asbestosis and mesothelioma. Exposure to asbestos fibres can occur in a variety of ways including contact with contaminated clothing or materials. The dangers of exposure are heightened when crocidolite which is the asbestos' blue form, is involved. Crocidolite fibers are thinner and more fragile and therefore easier to inhale. They can also lodge deeper into lung tissues. It has been associated with more mesothelioma cancer cases than other asbestos types.
The six main types are chrysotile as well as amosite. The most well-known forms of asbestos are epoxiemite and chrysotile which together make up 95% all commercial asbestos employed. The other four have not been as widely utilized however, they could be present in older buildings. They are less hazardous than chrysotile or amosite but can still be a danger when combined with other minerals or when mined near other naturally occurring mineral deposits, such as talc and vermiculite.
Numerous studies have proven an association between stomach cancer and asbestos exposure. The evidence is contradictory. 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 workers working in chrysotile mining and mills.
The International Agency for Research on Cancer (IARC) has classed all asbestos types as carcinogenic. All asbestos types can cause mesothelioma however, the risk is dependent on the amount of exposure, the type of asbestos is involved and how long exposure lasts. IARC has declared that the best option for individuals is to stay clear of all forms of asbestos. If you have been exposed to asbestos and suffer from respiratory issues or mesothelioma, then you should consult your GP or NHS111.
Amphibole
Amphibole is one of the minerals that form long prism or needlelike crystals. They are a kind of inosilicate mineral made up of double chains of molecules of SiO4. They usually possess a monoclinic crystal system but some also have 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 that are linked in rings of six. The tetrahedrons are separated by octahedral strips.
Amphiboles can be found in metamorphic and igneous rock. They are typically dark and hard. Due to their similarity in strength and colour, they can be difficult for some to differentiate from Pyroxenes. They also have a comparable Cleavage. Their chemistry allows for a range of compositions. The chemical compositions and crystal structures of the different mineral groups in amphibole could be used to determine their composition.
Amphibole asbestos litigation comprises chrysotile and the five asbestos types amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. While the most popular form of asbestos is chrysotile, each variety is unique in its own way. The most dangerous form 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 composed of iron and magnesium. This kind of stone was used to create cement and insulation materials.
Amphiboles can be difficult to study because of their complex chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires specialized techniques. EDS, WDS and XRD are the most popular methods of identifying amphiboles. 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 and pargasite.
