The Dangers of Exposure to Asbestos

Before it was banned asbestos was used in a myriad of commercial products. According to research, asbestos exposure can cause cancer and many other health issues.

It is not possible to tell by simply looking at something whether it is made up of asbestos. You cannot taste or smell it. Asbestos is only detected when the materials that contain it are broken or drilled.

Chrysotile

At its peak, chrysotile made the majority of asbestos production. It was widely used in industries including construction, insulation, and fireproofing. Unfortunately, if workers were exposed to the toxic material, they could develop mesothelioma, as well as other asbestos-related diseases. Since the 1960s, when mesothelioma was first becoming a concern, the use of asbestos has been reduced significantly. However, it is still present in trace amounts. are still present in the products we use in the present.

Chrysotile is safe to use when you have a thorough safety and handling program in place. It has been determined that at the present exposure levels, there is no undue risk to the workers who handle it. The inhalation of airborne fibres has been strongly associated with lung fibrosis and lung cancer. This has been confirmed both for the intensity (dose) as well as the duration of exposure.

In one study, mortality rates were compared between a factory that primarily used Chrysotile for the production of friction materials and the national death rate. The study concluded that, after 40 years of processing at low levels of chrysotile, there was no significant increase in mortality rates in this factory.

Contrary to other types of asbestos, chrysotile fibers tend to be shorter. They can enter the lungs, and enter the bloodstream. This makes them more prone to causing health consequences than longer fibres.

When chrysotile gets mixed with cement, it's very difficult for the fibres to air-borne and pose health risks. Fibre cement products are utilized in many areas of the world, including schools and hospitals.

Research has revealed that amphibole asbestos such as amosite or crocidolite is less likely than chrysotile to cause diseases. Amphibole asbestos types have been the primary source of mesothelioma, as well as other asbestos-related diseases. When chrysotile is mixed in with cement, it creates a strong, flexible construction product that can withstand extreme 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 term used to describe a class of fibrous silicate minerals which are found naturally in a variety of types of rock formations. It is comprised of six main groups: amphibole, serpentine, tremolite, anthophyllite and crocidolite (IARC 1973).

Asbestos minerals are made up of thin, long fibers that vary in length from fine to wide. They can be curled or straight. They can be found in nature in bundles, or as individual fibrils. Asbestos can also be found in powder form (talc) or mixed with other minerals to create talcum powder or vermiculite. These are widely used in consumer products such as baby powder, cosmetics, and face powder.

asbestos attorney was widely used during the early two-thirds of the 20th century for shipbuilding insulation, fireproofing and various other construction materials. Most occupational exposures were asbestos fibres that were borne in the air, but certain workers were exposed to vermiculite or talc that was contaminated, and to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied from industry industry, from era to and even geographical location.

Exposure to asbestos in the workplace is mostly because of inhalation. However there have been instances of workers being exposed through skin contact or by eating food items contaminated with asbestos. Asbestos can only be found in the natural environment due to natural weathering and the degradation of contaminated products like ceiling and floor tiles, car brakes and clutches as well as insulation.

It is becoming clear that non-commercial amphibole fibres may also be carcinogenic. These fibres are not tightly weaved like the fibrils in amphibole or serpentine, they are loose and flexible, and needle-like. These fibres are found in the mountains and cliffs 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 the anthropogenic (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination of ground and surface water is mostly a result of natural weathering, but it has also been triggered by anthropogenic activities like milling and mining, asbestos attorney demolition and dispersal of asbestos-containing material and the disposal of contaminated soils for disposal in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary cause of illness in people exposed to asbestos during their work.

Crocidolite

Inhalation exposure to asbestos is the most common way people are exposed dangerous fibres, which can then get into the lungs and cause serious health issues. This includes asbestosis and mesothelioma. Exposure to fibres can occur in different ways too including contact with contaminated clothing or materials. This type of exposure is particularly dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is smaller and more fragile fibers that are easier to inhale and can lodge deeper in lung tissue. It has been associated with more mesothelioma cases than other asbestos types.

The six main types of asbestos are chrysotile, amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. Amosite and chrysotile are the most frequently used types of asbestos and account for 95 percent of all commercial asbestos currently used. The other four have not been as extensively used however they can be found in older buildings. They are less hazardous than chrysotile and amosite, but they can pose a risk when mixed with other asbestos minerals, or when mined in close proximity to other mineral deposits, such as talc or vermiculite.

Numerous studies have revealed an association between stomach cancer and Asbestos Attorney asbestos exposure. However the evidence is not conclusive. Certain 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 mines and mills.

IARC the International Agency for Research on Cancer has classified all kinds of asbestos carcinogenic. All asbestos types can cause mesothelioma however, the risk is dependent on the amount of exposure, what type of asbestos is involved, and how long exposure lasts. IARC has stated that the best choice for people is to stay clear of all types of asbestos. If someone has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma, or other respiratory ailments it is recommended that they seek advice from their GP or NHS 111.

Amphibole

Amphibole is a class of minerals that form long prism or needle-like crystals. They are a type inosilicate mineral that is composed of double chains of molecules of SiO4. They typically have a monoclinic structure in their crystals however, 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 series of six tetrahedrons. The tetrahedrons can be separated from one another with octahedral strips.

Amphiboles are present in both igneous and metamorphic rock. They are typically dark-colored and are hard. They are sometimes difficult to distinguish from pyroxenes as they share similar hardness and colors. They also share a similar design of cleavage. Their chemistry can allow for a variety of compositions. The various minerals within amphibole can be identified by their chemical compositions as well as crystal structures.

The five asbestos types that belong to the amphibole group include amosite, anthophyllite and chrysotile and crocidolite. They also include actinolite. Each kind of asbestos has distinct characteristics. Crocidolite is the most hazardous asbestos law type. It is made up of sharp fibers that can be easily inhaled into the lungs. Anthophyllite comes in a brownish-to yellowish hue and is made primarily of magnesium and iron. This kind of material was used to create cement and insulation materials.

Amphibole minerals are difficult to analyze because they have a complex chemical structures and many substitutions. Therefore, a detailed analysis of their composition requires special methods. EDS, WDS and XRD are the most common methods for identifying amphiboles. These methods can only provide approximate identifications. For instance, they are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. These techniques also cannot distinguish between ferro-hornblende as well as pargasite.
