The Dangers of Exposure to Asbestos
Before it was banned, asbestos was still used in a variety of commercial products. Research has shown that exposure to asbestos can cause cancer and other health problems.
It is impossible to determine if a product has asbestos just simply by looking at it and you won't be able to smell or taste it. It is only found when asbestos-containing materials are chipped, drilled or broken.
Chrysotile
At the height of its use, chrysotile made the majority of the asbestos produced. It was used by many industries including construction, fireproofing, and insulation. If workers are exposed to asbestos, they may develop mesothelioma as well as other asbestos-related illnesses. Thankfully, the use this hazardous mineral has declined significantly since awareness of mesothelioma began to spread in the 1960's. However, it is still present in trace amounts. remain in the products we use in the present.
Chrysotile is safe to use in the event that you have a complete safety and handling plan in place. It has been found that at the current controlled exposure levels, there is no unneeded risk to the people who handle it. Lung cancer, lung fibrosis and mesothelioma have been strongly linked to breathing in airborne respirable fibres. This has been proven both for intensity (dose) as well as duration of exposure.
In one study, mortality rates were compared among a factory which used largely Chrysotile for the production of friction materials and national death rates. The study concluded that, after 40 years of converting low levels of chrysotile, there was no significant rise in mortality rates at this facility.
Contrary to other types of asbestos, chrysotile fibers tend to be smaller. They are able to penetrate the lungs, and then pass through the bloodstream. They are more likely to cause health problems than fibres that are longer.
When chrysotile mixes with cement, it is extremely difficult for the fibres to become airborne and pose health risks. The fibre cement products are extensively used across the globe particularly in structures such as schools and hospitals.
Research has revealed that amphibole asbestos, such as amosite or crocidolite is not as likely than chrysotile in causing diseases. These amphibole types have been the most common source of mesothelioma, as well as other asbestos-related diseases. When chrysotile is mixed in with cement, it forms a strong, flexible building product that is able to withstand severe conditions in the weather and other environmental dangers. It is also simple to clean after use. Asbestos fibers can be easily removed by a professional and disposed of.
Amosite
Asbestos is a category of fibrous silicates that are found in certain types rock formations. It is comprised of six main groups: serpentine, amphibole, tremolite, anthophyllite and crocidolite (IARC, 1973).
Asbestos minerals consist of long, thin fibers that vary in length from fine to broad. They can also be curled or straight. These fibres can be found in nature in bundles or as individual fibrils. Asbestos is also found in powder form (talc) or mixed with other minerals in order to create vermiculite or talcum powder. These are widely used as consumer products, like baby powder, cosmetics, and even face powder.
The greatest asbestos use was during the early two-thirds of the 20th century, when it was used in insulation, shipbuilding, fireproofing, and other construction materials. The majority of asbestos exposures for work occurred in the air, but some workers also were exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied from industry industry, era to and even geographical location.
The exposure to asbestos in the workplace is mostly because of inhalation. However there are workers who have been exposed via skin contact or eating contaminated foods. Asbestos is only found in the air due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles cars, brakes and clutches as well as insulation.
It is becoming evident that non-commercial amphibole fibers could also be carcinogenic. These are fibres do not have the tight woven fibrils of the amphibole or serpentine minerals but instead are loose, flexible and needle-like. These fibres are found in the cliffs and mountains from a variety of countries.
Asbestos is absorbed into the environment mostly in the form of airborne particles, however it also leaches 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 wastes in landfill sites) sources. Asbestos contamination in ground and surface water is mostly caused by natural weathering. However it can also be caused by anthropogeny, such as through milling and mining of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated waste in landfills (ATSDR 2001). Airborne asbestos fibres are the primary reason for illness among those exposed to asbestos during their occupation.
Crocidolite
Inhalation exposure to asbestos is the most common way people are exposed to harmful fibres, which could then get into the lungs and cause serious health issues. Mesothelioma and asbestosis as well as other illnesses can be caused by asbestos fibres. Exposure to asbestos fibres can occur in other ways, too including contact with contaminated clothing, or building materials. This type of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are less dense and more fragile, making them easier to inhale. They can also get deeper in lung tissue. It has been linked to more mesothelioma-related cases than other asbestos types.
The six primary kinds are chrysotile and amosite. Amosite and chrysotile are two of the most frequently used types of asbestos and account for 95% of the commercial asbestos currently used. The other four asbestos types aren't as well-known, but can still be present in older structures. They are not as dangerous as chrysotile or amosite but can still be a danger when combined with other minerals or when mined near other mineral deposits such as talc and vermiculite.
Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. However the evidence isn't conclusive. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all asbestos compensation-related workers as well as an SMR of 1.24 (95% C.I. 0.76-2.5) for workers in chrysotile mines and mills.
The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All kinds of asbestos can cause mesothelioma or other health problems, but the risks are different based on how much exposure individuals are exposed to, the type of asbestos used, the duration of their exposure, and the manner in which it is inhaled or ingested. The IARC has advised that avoiding all forms of asbestos should be the top priority because this is the safest option for those who are exposed. If you have been exposed in the past to asbestos and suffer from a respiratory illness or mesothelioma then you should talk to your doctor or NHS111.
Amphibole
Amphiboles are a collection of minerals that can form prism-like or needle-like crystals. They are an inosilicate mineral that is composed of two chains of SiO4 molecules. They typically 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 contain (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. The tetrahedrons can be separated by octahedral strips.
Amphiboles can be found in metamorphic and igneous rock. They are usually dark-colored and hard. Due to their similarity of hardness and colour, they can be difficult for some to differentiate from Pyroxenes. They also share a corresponding the cleavage pattern. However, their chemistry allows for many different compositions. The chemical compositions and crystal structure of the various mineral groups found in amphibole may be used to identify them.
Amphibole asbestos consists of chrysotile, and the five types of asbestos: amosite, anthophyllite (crocidolite) amosite (actinolite), and amosite. Each type of asbestos comes with its own distinct properties. Crocidolite is considered to be the most hazardous asbestos type. It has sharp fibers that can be easily breathed into the lungs. Anthophyllite ranges from brown to yellowish in color and is made up of magnesium and iron. This type was used to make cement and insulation materials.
Amphiboles are difficult to analyse because of their complex chemical structure and numerous substitutions. A thorough analysis of composition of amphibole mineral requires specialized methods. The most common methods for identifying amphiboles are EDS, mesothelioma WDS, and XRD. These methods are only able to provide approximate identifications. For instance, these methods cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques also do not distinguish between ferro-hornblende and.
