The Dangers of Exposure to Asbestos

Asbestos was a component in thousands of commercial products prior to when it was banned. According to studies, exposure to asbestos can cause cancer, as well as other health problems.

It is difficult to tell if something contains asbestos by looking at it and you won't be able to smell or taste it. It is only visible when the asbestos-containing materials are chipped, drilled or broken.

Chrysotile

At its peak, chrysotile made the majority of the asbestos production. It was employed in a variety of industries, including construction insulation, fireproofing, and insulation. If workers were exposed to this toxic material, they could develop mesothelioma, as well as other asbestos legal-related diseases. Thankfully, the use of this harmful mineral has diminished significantly since awareness of mesothelioma began to increase in the 1960's. It is still present in a variety of products we use today.

Chrysotile is safe to use provided you have a comprehensive safety and handling program in place. Chrysotile handling workers aren't exposed to an unreasonable amount of risk at the present limits of exposure. Inhaling airborne fibres is strongly linked to lung cancer and lung fibrosis. This has been proven to be true for both intensity (dose) and time span of exposure.

One study that looked into a factory that used almost exclusively chrysotile in the production of friction materials, compared mortality rates in this factory with national death rates. It was discovered that, for 40 years of processing asbestos chrysotile at a low level of exposure, there was no significant additional mortality in this factory.

Contrary to other types of asbestos, chrysotile fibres tend to be smaller. They can penetrate the lungs and then enter the bloodstream. They are more likely to cause health issues than fibres with longer lengths.

When chrysotile gets mixed with cement, it's extremely difficult for the fibres to become airborne and cause health hazards. Fibre cement products have been extensively used throughout the world particularly in structures such as schools and hospitals.

Research has proven that amphibole asbestos, like amosite, crocidolite, or crocidolite, is less likely than chrysotile to cause disease. These amphibole types have been the primary cause of mesothelioma and other asbestos-related illnesses. When chrysotile mixes with cement, it forms a strong, flexible construction product that can withstand harsh conditions in the weather and other environmental hazards. It is also simple to clean after use. Professionals can safely get rid of asbestos fibres after they have been removed.

Amosite

Asbestos is a term used to describe a class of silicate fibrous minerals that are found naturally in specific kinds of rock formations. It is comprised of six general groups: amphibole, serpentine, tremolite, anthophyllite and crocidolite (IARC 1973).

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

The most extensive asbestos use was during the first two-thirds of twentieth century in the period when it was employed in shipbuilding, insulation, fireproofing and other construction materials. The majority of occupational exposures involved asbestos fibres that were borne in the air, but certain workers were exposed to vermiculite or talc that was contaminated and to pieces of asbestos-bearing rocks (ATSDR, 2001). Exposures varied from industry to industry, era to, and geographical location.

Most asbestos exposures that workers were exposed to was because of inhalation, but some workers were also exposed through contact with skin or by eating food contaminated with asbestos. Asbestos is 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.

There is evidence to suggest that amphibole fibers that are not commercially available could also be carcinogenic. These are fibers that do not have the tight weaved fibrils of amphibole or serpentine minerals but instead are flexible, loose and needle-like. These fibers are found in the cliffs and mountains from a variety of countries.

Asbestos Attorney is able to enter the environment in a variety of ways, including in the form of airborne particles. It is also able to leach into soil or water. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination in ground and surface waters is primarily caused through natural weathering. However it is also caused by humans, 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). Asbestos fibres that are emitted from the air are the primary cause of illness among people exposed to asbestos in their occupation.

Crocidolite

Inhalation exposure to asbestos is the most frequent method by which people are exposed to harmful fibres that can then get into the lungs and cause serious health issues. Mesothelioma and asbestosis as well as other diseases can be caused by asbestos fibres. The exposure to asbestos fibres could occur in different ways, including contact with contaminated clothing or building materials. This type of exposure is particularly dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are less dense and more fragile and therefore easier to inhale. They can also lodge deeper into lung tissue. It has been linked to more mesothelioma cases than other types of asbestos.

The six main types of asbestos are chrysotile amosite, epoxiemite, tremolite anthophyllite and actinolite. The most well-known forms of asbestos are epoxiemite and chrysotile which together comprise 95% all commercial asbestos used. The other four have not been as popularly used, but they may still be found in older buildings. They aren't as hazardous as amosite or chrysotile, but they can still be a danger when mixed with other minerals, or when mined near other naturally occurring mineral deposits such as talc and vermiculite.

Numerous studies have revealed an association between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. However, the evidence is contradictory. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, whereas others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for workers in chrysotile mills and mines.

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 issues, although the risks vary according to how much exposure individuals are exposed to, the kind of asbestos used and the duration of their exposure, and the manner in the way it is inhaled or ingested. The IARC has recommended that avoiding all forms of asbestos is the best option as it is the most safe option for individuals. If you have been exposed to asbestos and suffer from respiratory issues or mesothelioma, then you should consult your GP or NHS111.

Amphibole

Amphibole belongs to a group of minerals that form long prism or needle-like crystals. They are a type of inosilicate mineral made up of double chains of SiO4 molecules. They typically possess a monoclinic crystal system however, some 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 linked together in a ring of six tetrahedrons. The tetrahedrons can be separated from each other with octahedral strips.

Amphiboles can be found in metamorphic and igneous rock. They are usually dark-colored and tough. Because of their similar hardness and color, they may be difficult for some people to differentiate from Pyroxenes. They also have a similar the cleavage. Their chemistry permits a wide range of compositions. The different minerals within amphibole can be identified by their chemical compositions as well as crystal structures.

The five types of asbestos belonging to the amphibole family are amosite, anthophyllite and chrysotile and crocidolite. They also include actinolite. Each type of asbestos has distinct characteristics. The most dangerous type of asbestos, crocidolite, is composed of sharp fibers that are easy to inhale into the lungs. Anthophyllite is a brownish to yellowish color and is composed mostly of iron and magnesium. This variety was used to make cement and insulation materials.

Amphiboles are difficult to analyze due to their complicated chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires specialized methods. EDS, WDS and XRD are the most popular methods of identifying amphiboles. These methods are only able to provide approximate identifications. For instance, they cannot differentiate between magnesio-hastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro-hornblende and pargasite.
