The Dangers of Exposure to Asbestos

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

You can't tell if something has asbestos just by looking at it, and you won't be able to smell or taste it. Asbestos is only detectable when the materials that contain it are broken or Vimeo drilled.

Chrysotile

At its height, chrysotile comprised up 99% of the asbestos production. It was used by many industries which included construction insulation, fireproofing and insulation. If workers are exposed to asbestos, they are likely to develop mesothelioma as well as other asbestos-related illnesses. Since the 1960s, when mesothelioma began to become an issue asbestos use has decreased significantly. However, trace amounts are still present in common products that we use today.

Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. People who handle chrysotile do not exposed to an unreasonable amount of risk at the present limits of exposure. Lung cancer, lung fibrosis and mesothelioma have been strongly linked to breathing in airborne respirable fibres. This has been proven for both the intensity (dose) and the duration of exposure.

A study that looked at the operation of a factory that utilized almost exclusively chrysotile for manufacturing friction materials, compared mortality rates at this factory with national mortality rates. The study found that after 40 years of manufacturing low levels of chrysotile there was no significant increase in mortality rates in this factory.

Chrysotile fibres tend to be shorter than other forms of asbestos. They can penetrate the lungs and enter the bloodstream. They are more likely to cause health problems than longer fibres.

It is very difficult for chrysotile fibres be inhaled or to pose a health risk when mixed with cement. Fibre cement products are extensively used in various parts of the world including hospitals and schools.

Research has shown that amphibole asbestos, like crocidolite or amosite is less likely to cause disease. These amphibole types are the primary source of mesothelioma as well as other asbestos-related diseases. When cement and chrysotile mix and cured, a tough and flexible product is created that is able to withstand extreme weather conditions and environmental hazards. It is also easy to clean after use. Asbestos fibers can be easily removed by a professional, and then disposed of.

Amosite

Asbestos is a class of fibrous silicates that are found in certain types rock formations. It is composed of six general groups: serpentine, amphibole anthophyllite, tremolite and crocidolite (IARC 1973).

Asbestos minerals are composed of long, thin fibers that range in length from fine to broad. They can be curled or straight. They are found in nature in bundles or as individual fibrils. Asbestos minerals can be found in the form of a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder that are widely used in consumer products like baby powder cosmetics, face powder and baby powder.

Asbestos was extensively used in the early two-thirds of the 20th century for construction of ships, insulation, fireproofing, and various other construction materials. Most occupational exposures were airborne asbestos fibres, but certain workers were exposed to toxic talc or vermiculite and also to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied from industry industry, era to and even geographical location.

Most asbestos-related exposures in the workplace were due to inhalation, but some workers were also exposed through contact with skin or through eating contaminated food. Asbestos is only present in the environment from the natural weathering of mined ore and the deterioration of products contaminated with asbestos such as insulation, car brakes, clutches as well as ceiling and floor tiles.

There is emerging evidence that amphibole fibers that are not commercially available could also be carcinogenic. These are the fibres that don't form the tightly interwoven fibrils that are found in the amphibole and serpentine minerals but instead are flexible, loose and needle-like. These fibres are found in the cliffs and mountains of several countries.

Asbestos is absorbed into the environment mostly as airborne particles, but it can also leach into water and soil. This is caused by both natural (weathering of st louis asbestos lawyer-bearing rocks) and anthropogenic causes (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of surface and ground water is largely associated with natural weathering, however it has also been caused by human activities such as mining and milling demolition and dispersal of asbestos-containing material and the disposal of contaminated soils for disposal in landfills (ATSDR 2001). The inhalation of mesquite asbestos lawyer fibres is still the primary cause of illness in people exposed to it occupationally.

Crocidolite

Exposure to asbestos through inhalation is the most popular way people are exposed to the harmful fibres. They can then be inhaled and cause serious health problems. Mesothelioma, asbestosis and other diseases are all caused by asbestos fibres. The exposure to asbestos can happen in a variety of ways like contact with contaminated clothing, or building materials. The dangers of exposure are more pronounced when crocidolite (the asbestos that is blue, is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe in and can get deeper into lung tissue. It has been linked to more mesothelioma-related cases than other types of asbestos.

The six main types of asbestos are chrysotile amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. The most common asbestos types are epoxiemite and chrysotile, which together comprise the majority of commercial asbestos employed. The other four have not been as popularly used but they can be present in older buildings. They aren't as hazardous as amosite or chrysotile however they could still pose a threat when combined with other minerals or when mined near other naturally occurring mineral deposits like talc and vermiculite.

A number of studies have demonstrated an association between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. However, the evidence is contradictory. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95 percent CI: 0.76-2.5) for those who work in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All types of asbestos can cause mesothelioma and other health issues, although the risks differ based on the amount of exposure that individuals are exposed to, the kind of asbestos used and the duration of their exposure and the manner in which it is inhaled or ingested. The IARC has advised that the prevention of all asbestos types should be the highest priority as it is the best option for people. If you have been exposed in the past to kokomo Asbestos Attorney and are suffering from a respiratory disorder or mesothelioma then you should talk to your doctor or NHS111.

Amphibole

Amphiboles comprise a variety of minerals that can form needle-like or prism-like crystals. They are a kind of inosilicate mineral composed of double chains of SiO4 molecules. They typically have a monoclinic crystal structure however some may 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 rings of six tetrahedrons. The tetrahedrons are separated from each other by octahedral sites in strips.

Amphibole minerals are common in metamorphic and igneous rocks. They are typically dark and hard. Due to their similarity in hardness and color, they could be difficult for some to differentiate from the pyroxenes. They also have a similar the cleavage. However their chemistry allows the use of a variety of compositions. The chemical compositions and crystal structure of the different minerals in amphibole can be used to determine their composition.

The five asbestos types that belong to the amphibole group include chrysotile, anthophyllite, amosite, crocidolite, and actinolite. The most widely used form of asbestos is chrysotile each type has its own unique characteristics. Crocidolite is considered to be the most hazardous asbestos kind. It is made up of sharp fibers that can be easily inhaled into the lung. Anthophyllite ranges from brown to yellowish in color and is made up of iron and magnesium. This type was used to make cement and insulation materials.

Amphiboles are difficult to analyse due to their complex chemical structure and numerous substitutions. An in-depth analysis of the composition of amphibole mineral requires specialized techniques. EDS, WDS and XRD are the most popular methods of identifying amphiboles. However, these methods only give approximate identifications. These methods, for instance, cannot distinguish between magnesio hornblende and hastingsite. Additionally, these techniques do not distinguish between ferro-hornblende and pargasite.
