The Dangers of Exposure to Asbestos

Asbestos was a component in thousands of commercial products before it was banned. Research has shown that exposure to asbestos claim can cause cancer as well as other health issues.

You can't tell if something includes asbestos simply by looking at it and you can't smell or taste it. It can only be found when asbestos-containing materials are chipped, drilled or broken.

Chrysotile

At its height, chrysotile comprised the majority of the asbestos production. It was used in many industries, including construction, insulation, and fireproofing. If workers were exposed to this harmful material, they could develop mesothelioma or other asbestos related diseases. Fortunately, the use of this toxic mineral has decreased drastically since mesothelioma awareness started to spread in the 1960's. It is still found in many of the products we use in the present.

Chrysotile is safe to use when a thorough safety and handling plan is put into place. Personnel handling chrysotile aren't exposed to an undue amount of risk at the present limits of exposure. Inhaling airborne fibers has been found to be strongly linked with lung cancer and lung fibrosis. This has been proven both in terms of intensity (dose) as well as 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 death rates. It was discovered that, for 40 years of processing asbestos chrysotile at a low level of exposure There was no significant extra mortality in the factory.

Chrysotile fibres are usually shorter than other forms of asbestos. They can enter the lungs and enter the bloodstream. This makes them more likely to cause ill-health effects than longer fibres.

When chrysotile gets mixed with cement, it is very difficult for the fibres to air-borne and pose health risks. Fibre cement products are widely used in many parts of the world, including schools and Asbestos litigation hospitals.

Research has shown that chrysotile has a lower chance to cause disease than amphibole asbestos like amosite and crocidolite. Amphibole asbestos forms have been the primary cause of mesothelioma and other asbestos-related diseases. When cement and chrysotile mix and cured, a tough, flexible product is created that can withstand extreme environmental hazards and weather conditions. It is also easy to clean after use. Professionals can safely dispose of asbestos fibres after they have been removed.

Amosite

Asbestos refers to a set of fibrous silicate minerals that are found naturally in specific kinds of rock formations. It is divided into six groups that include amphibole (serpentine), tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals are made up of thin, long fibers that vary in length from fine to broad. They can also be curled or straight. They are present in nature as individual fibrils or as bundles with splaying ends called a fibril matrix. Asbestos minerals are also found in the form of a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite, which have been widely used in consumer products, such as baby powder cosmetics, face powder, and baby powder.

The greatest asbestos use occurred during the first two-thirds of twentieth century when it was utilized in shipbuilding, insulation, fireproofing, and other construction materials. The majority of occupational exposures were airborne asbestos fibres, but some workers were exposed to vermiculite and talc that had been contaminated, and to fragments of asbestos-bearing rocks (ATSDR, 2001). Exposures varied from industry industry, era to era, and geographical location.

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

It is becoming increasingly apparent that amphibole fibers that are not commercially available could also be carcinogenic. These are fibres do not form the tightly weaved fibrils of serpentine and amphibole minerals, but instead are flexible, loose and needle-like. These fibers can be found in the mountains, sandstones and cliffs of a variety of countries.

Asbestos enters the environment mainly as airborne particles, but it also leaches into water and soil. This can be due to both natural (weathering of asbestos-bearing rocks) and anthropogenic sources (disintegration of asbestos attorney-containing wastes and disposal in landfill sites). Asbestos contamination in surface and ground waters is primarily caused through natural weathering. However, it has also been caused by anthropogeny, such as through the mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated dumping material in landfills (ATSDR 2001). Airborne asbestos fibres are the main cause of illness in people who are exposed to it during their work.

Crocidolite

Exposure to asbestos through inhalation is the most frequent method by which people are exposed to dangerous fibres, which can then get into the lungs and cause serious health issues. These include asbestosis and mesothelioma. Exposure to asbestos fibers can occur in different ways, like contact with contaminated clothing or building materials. This type of exposure is especially dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are thinner and more fragile and therefore easier to breathe in. They can also be lodged deeper inside lung tissues. It has been associated with more mesothelioma cancer cases than other asbestos types.

The six primary types are chrysotile and amosite. Amosite and chrysotile are the most commonly used types of asbestos, and comprise 95% of all commercial asbestos currently used. The other four have not been as popularly used, but they may still be found in older buildings. They are less hazardous than amosite and chrysotile, however they may pose a danger when combined with other asbestos minerals or when mined close to other naturally occurring mineral deposits, like vermiculite or talc.

Many studies have discovered an association between exposure to asbestos and stomach cancer. A number of studies have confirmed that asbestos exposure is linked to stomach. However there is no conclusive evidence. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95 percent 95% confidence interval: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95% of the CI = 0.76-2.5) for workers working in chrysotile mining and mills.

IARC The IARC, also known as the International Agency for Research on Cancer has classified all kinds of asbestos litigation (https://tw.ipdrivers.Com/) carcinogenic. All asbestos types can cause mesothelioma however, the risk is dependent on how much exposure, the type of asbestos is involved and how long exposure lasts. IARC has stated that the best choice for individuals is to stay clear of all types of asbestos. However, if a person has been exposed to asbestos in the past and are suffering from a condition such as mesothelioma and other respiratory ailments it is recommended that they seek advice from their physician or NHS 111.

Amphibole

Amphiboles are a grouping of minerals that form prism-like or needle-like crystals. They are an inosilicate minerals made of double chains of SiO4 molecules. They typically have a monoclinic structure in their crystals but some also have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains comprise (Si, Al)O4 tetrahedrons linked together by tetrahedron rings made of six. Tetrahedrons are distinguished from each other by octahedral sites in strips.

Amphiboles are present in both igneous and metamorphic rock. They are usually dark-colored and are hard. Due to their similarity in hardness and color, they can be difficult for some to distinguish from Pyroxenes. They also share a corresponding cleavage pattern. However their chemistry allows the use of a variety of compositions. The various mineral groups in amphibole can be identified by their chemical compositions as well as crystal structures.

Amphibole asbestos includes chrysotile and the five types of asbestos case: amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. While the most commonly used form of asbestos is chrysotile. Each variety has its own distinct characteristics. The most dangerous type of asbestos, crocidolite is composed of sharp fibers that are simple to breathe into the lung. Anthophyllite can range from yellow to brown in color and is made up of magnesium and iron. This kind of material was used to create cement and insulation materials.

Amphibole minerals are hard to analyze because they have a an intricate chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires specialized techniques. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. However, these methods can only provide approximate identifications. These techniques, for example, cannot distinguish between magnesio hornblende and hastingsite. These techniques also cannot distinguish between ferro-hornblende and pargasite.
