The Dangers of Exposure to Asbestos

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

It is impossible to determine if a product includes asbestos by looking at it, and you cannot taste or smell it. It is only found when the asbestos-containing materials are chipped, drilled or broken.

Chrysotile

At its height, chrysotile provided for Asbestos Attorney 90% of the asbestos that was produced. It was widely used in industries, including construction, insulation, and fireproofing. If workers were exposed to this harmful material, they may develop mesothelioma, as well as other asbestos-related diseases. Thankfully, the use of this hazardous mineral has declined drastically since mesothelioma awareness started to spread in the 1960's. It is still present in a variety of products we use in the present.

Chrysotile can be used in a safe manner in the event that a thorough safety and handling plan is put in place. Personnel handling chrysotile aren't exposed to an undue amount of risk at the current safe exposure levels. Lung cancer, lung fibrosis and mesothelioma have been strongly connected to breathing in airborne respirable fibres. This has been confirmed for both intensity (dose) and the duration of exposure.

In one study mortality rates were compared between a manufacturing facility which used largely Chrysotile for the production of friction materials and the national death rate. It was concluded that over the course of 40 years, processing asbestos chrysotile at low levels of exposure there was no signifi cant additional mortality in this factory.

As opposed to other forms of asbestos litigation, chrysotile fibers tend to be shorter. They can pass through the lungs and enter the bloodstream. They are more likely to cause health issues than fibres that are longer.

When chrysotile is mixed with cement, it's very difficult for the fibres to become airborne and pose any health risks. Fibre cement products have been extensively used across the globe particularly in buildings such as schools and hospitals.

Research has revealed that amphibole asbestos such as amosite or crocidolite is not as likely to cause diseases. Amphibole asbestos types have been the primary source of mesothelioma, as well as other asbestos-related diseases. When chrysotile is combined with cement, it forms a tough, flexible building product that can withstand extreme weather conditions and other environmental hazards. It is also easy to clean after use. Asbestos fibres are easily removed by a professional and then safely removed.

Amosite

Asbestos is a category of silicate fibrous minerals that naturally occur in certain types of rock formations. It is comprised of six main groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC 1973).

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

The greatest asbestos use occurred during the early two-thirds of the 20th century where it was used in shipbuilding, insulation, fireproofing, and other construction materials. Most occupational exposures were to airborne asbestos fibres, but some workers were exposed contaminated vermiculite or talc as well as to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied by the industry, time frame, and geographic location.

The majority of occupational exposures to asbestos were because of inhalation, but some workers were also exposed via skin contact or through eating contaminated food. Asbestos can only be found in the environment due to natural weathering and degrading of contaminated materials like ceiling and floor tiles cars, brakes and clutches, and insulation.

There is evidence emerging that amphibole fibers that are not commercially available could also be carcinogenic. These fibers aren't tightly knit like the fibrils found in amphibole and serpentine, they are loose, flexible, and needle-like. These fibers are found in the mountains and cliffs from a variety of countries.

Asbestos gets into the environment primarily in the form of airborne particles, however it also leaches into water and soil. This is a result of both natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos attorney contamination of surface and ground water is typically a result of natural weathering, however it has also been caused by anthropogenic activities like mining and milling, demolition and dispersal of asbestos-containing materials, and the removal of contaminated dumping soils in landfills (ATSDR, 2001). Asbestos fibres that are emitted from the air are the main cause of disease among those exposed to asbestos in their work.

Crocidolite

Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can infiltrate the lungs and cause serious health issues. These include asbestosis and mesothelioma. Exposure to fibers can occur in other ways, too, such as contact with contaminated clothing, or building materials. This kind of exposure is particularly dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is a smaller, more fragile fibers that are easy to breathe and can be lodged deeper in lung tissue. It has been linked to a larger number of mesothelioma-related cases than any other form of asbestos.

The six main types of asbestos are chrysotile amosite, epoxiemite, tremolite anthophyllite, and actinolite. The most popular asbestos types are chrysotile and epoxiemite, which together comprise the majority of commercial asbestos employed. The other four asbestos types aren't as widespread, but they can still be found in older structures. They are less hazardous than amosite and chrysotile. However, they could be a risk when mixed with other asbestos minerals or when mined in close proximity to other naturally occurring mineral deposits, like vermiculite or talc.

Numerous studies have revealed an association between stomach cancer and asbestos exposure. However there is no conclusive evidence. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers. However, others have reported an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those who work in mines and chrysotile mills.

IARC, the International Agency for Research on Cancer, has classified all kinds of asbestos carcinogenic. All forms of asbestos could cause mesothelioma or other health issues, but the risks are different based on how much exposure individuals are exposed to, the kind of asbestos involved and the duration of their exposure and the way in which it is inhaled or ingested. IARC has declared that the best choice for people is to avoid all forms of asbestos. However, if people have been exposed to asbestos in the past and are suffering from a condition such as mesothelioma or any other respiratory conditions and require advice, they should seek out guidance from their physician or NHS 111.

Amphibole

Amphibole belongs to a group of minerals that form long prism or needlelike crystals. They are a type of inosilicate mineral composed of double chains of SiO4 molecules. 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 linked together in a ring of six tetrahedrons. Tetrahedrons can be separated by strips of octahedral sites.

Amphibole minerals can be found in igneous and metamorphic rocks. They are usually dark and hard. They can be difficult to distinguish from pyroxenes because they have similar hardness and color. They also share a corresponding Cleavage. Their chemistry permits a wide variety of compositions. The different mineral groups in amphibole can be identified by their chemical compositions as well as crystal structures.

Amphibole asbestos comprises chrysotile and the five types of asbestos amosite anthophyllite (crocidolite), amosite (actinolite), and amosite. Each kind of asbestos has its own distinctive properties. The most dangerous type of asbestos, crocidolite, is made up of sharp fibers that are simple to inhale into the lungs. Anthophyllite can range from yellow to brown in color and is composed of iron and magnesium. This kind of stone was used to create 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 special methods. The most common methods of identifying amphiboles include EDS, WDS, and XRD. These methods are only able to provide approximate identifications. These techniques, for example, cannot distinguish between magnesio hastingsite and magnesio hastingsite. Additionally, these techniques do not distinguish between ferro-hornblende and pargasite.
