The Dangers of Exposure to Asbestos

Before it was banned asbestos was used in thousands commercial products. Research suggests that exposure to asbestos can cause cancer as well as other health issues.

You cannot tell if something has asbestos just by looking at it and you cannot taste or smell it. Asbestos is only detectable when materials containing it are broken or drilled.

Chrysotile

At the height of its use, chrysotile made the majority of the asbestos production. It was employed in a variety of industries including construction, insulation, and fireproofing. If workers are exposed to asbestos, they could develop mesothelioma along with other asbestos-related illnesses. Since the 1960s, when mesothelioma first became an issue asbestos use has been drastically reduced. However, trace amounts of it are still present in common products that we use in the present.

Chrysotile is safe to use with a well-thought-out safety and handling plan is put into place. Personnel handling chrysotile aren't exposed to an unreasonable amount of risk at the current safe exposure levels. The inhalation of airborne fibres has been linked with lung fibrosis and lung cancer. This has been confirmed for intensity (dose) as well as duration of exposure.

In one study, mortality rates were compared among a factory that used a large proportion of Chrysotile for the production of friction materials and the national death rate. The study revealed that after 40 years of manufacturing low levels of chrysotile, there was no significant increase in mortality in this factory.

Chrysotile fibers are generally shorter than other types of asbestos. They can penetrate the lungs and then enter the bloodstream. This makes them much more prone to causing health effects than fibrils with a longer length.

When chrysotile mixes with cement, it is extremely difficult for the fibres to be airborne and pose any health risk. Fibre cement products are used extensively throughout the world, especially in buildings such as schools and hospitals.

Research has shown that chrysotile is less likely to cause illness than amphibole asbestos such as amosite and crocidolite. These amphibole types are the main cause of mesothelioma and other asbestos-related diseases. When chrysotile mixes with cement, it forms a strong, flexible construction product that can withstand harsh weather conditions and other environmental dangers. It is also easy to clean after use. Asbestos fibres are easily removed by a professional and removed.

Amosite

Asbestos is a grouping of fibrous silicates that are found in various types of rock formations. It is classified into six groups including amphibole (serpentine) and tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals are made up of long, thin fibers that range in length from fine to broad. They can also be straight or curled. They are found in nature as bundles or individual fibrils. Asbestos minerals can also be found in powder form (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 heavily used in the first two thirds of the 20th century for construction of ships as well as insulation, fireproofing and other construction materials. Most occupational exposures were airborne asbestos fibres, but certain workers were exposed to vermiculite and talc that had been contaminated as well as to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied from industry industry, era era and also from geographical location.

The exposure to asbestos at work is mostly caused by inhalation. However there are workers who have been exposed through skin contact or eating food that is contaminated. Asbestos is only present in the air due to natural weathering of mined ores and the degradation of contaminated products like insulation, car brakes and clutches, and floor and ceiling tiles.

There is emerging evidence that non-commercial amphibole fibres may also be carcinogenic. These fibers aren't tightly weaved like the fibrils that are found in amphibole or serpentine, but are instead loose and flexible, and needle-like. These fibres are found in the mountains and cliffs of several countries.

Asbestos can be absorbed into the environment in a variety ways, including as airborne particles. It is also able to leach into soil or water. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and the anthropogenic (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination of ground and surface water is mostly a result of natural weathering. However, it has also been caused by human activities such as milling and mining, demolition and dispersal of asbestos-containing material and the disposal of contaminated dumping ground in landfills (ATSDR, 2001). Inhalation exposure to asbestos fibers is the primary cause of illness for people exposed to asbestos at work.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can infiltrate the lungs and cause serious health problems. These include mesothelioma and asbestosis. Exposure to asbestos fibers can be experienced in other ways, including contact with contaminated clothes or building materials. This type of exposure is more dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are less dense and more fragile making them more palatable to inhale. They also can get deeper in lung tissues. It has been associated with more mesothelioma cancer cases than other types of asbestos.

The six major types of asbestos are chrysotile amosite, epoxiemite, tremolite, anthophyllite and actinolite. Chrysotile and amosite are among the most frequently used types of Asbestos attorney. They comprise 95% of the asbestos used in commercial construction. The other four forms haven't been as widely used however, they could be present in older buildings. They are not as dangerous as amosite or chrysotile, asbestos attorney but they can still pose a threat when mixed with other minerals, or when mined near other naturally occurring mineral deposits such as talc and vermiculite.

Several studies have found an association between exposure to asbestos and stomach cancer. However, the evidence is contradictory. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% of the time CI: 0.7-3.6) for all asbestos-related workers as well as an SMR of 1.24 (95 percent of the CI = 0.76-2.5) for those who work in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All kinds of asbestos can cause mesothelioma and other health issues, although the risks are different based on the amount of exposure people are exposed to, the type of asbestos involved as well as the length of their exposure and the way in the way that it is breathed in or consumed. IARC has stated that the best option for individuals is to avoid all forms of asbestos. If someone has been exposed to asbestos in the past and suffer from an illness such as mesothelioma and other respiratory ailments, they should seek guidance from their physician or NHS 111.

Amphibole

Amphibole is a group of minerals that form long prism or needlelike crystals. They are an inosilicate minerals made of double chains of SiO4 molecules. They usually have a monoclinic crystal system however some may have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. Double chains contain (Si, Al)O4 tetrahedrons linked together in a series of six tetrahedrons. Tetrahedrons can be separated by octahedral strips.

Amphiboles can be found in metamorphic and igneous rock. They are typically dark-colored and hard. Due to their similarity in hardness and color, they can be difficult for Asbestos Attorney some to differentiate from Pyroxenes. They also share a similar the cleavage pattern. Their chemistry allows for a variety of compositions. The chemical compositions and crystal structure of the different mineral groups found in amphibole may be used to determine their composition.

The five types of asbestos that belong to the amphibole group include chrysotile, anthophyllite, amosite as well as crocidolite and actinolite. Each kind of asbestos has distinct characteristics. The most hazardous type of asbestos, crocidolite is made up of sharp fibers that are simple to inhale into the lung. Anthophyllite is a brownish to yellowish color and is composed primarily of magnesium and iron. This variety was once used in products like cement and insulation materials.

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