The Dangers of Exposure to Asbestos

Asbestos was used in a variety of commercial products before it was banned. Research suggests that exposure to asbestos can cause cancer and other health problems.

It is impossible to determine if a product is asbestos-containing by looking at it, and you won't be able to taste or smell it. Asbestos can only be detected when the substances that contain it are broken, drilled, or chipped.

Chrysotile

At the height of its use, chrysotile made the majority of the asbestos production. It was widely used in industries including construction insulation, fireproofing, and construction. If workers are exposed to asbestos, they are likely to develop mesothelioma as well as other asbestos-related diseases. Fortunately, the use this hazardous mineral has declined significantly since awareness of mesothelioma began to increase in the 1960's. It is still found in many products we use in the present.

Chrysotile can be safely used when a thorough safety and handling plan is put in place. Workers handling chrysotile are not exposed to an undue amount of risk at current limits of exposure. Lung fibrosis, lung cancer and mesothelioma have all been found to be strongly associated with breathing in airborne respirable fibres. This has been confirmed for both the intensity (dose) and time of exposure.

In one study, mortality rates were compared between a manufacturing facility that primarily used Chrysotile in the production of friction materials and the national death rate. The study concluded that, after 40 years of processing at low levels of chrysotile there was no significant increase in mortality rates in this factory.

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

It is extremely difficult for chrysotile fibers to be airborne or pose any health risk when mixed with cement. Fibre cement products are extensively used throughout the world particularly in buildings like hospitals and schools.

Research has shown that chrysotile is less likely to cause disease than amphibole asbestos, like amosite and crocidolite. Amphibole asbestos types have been the most common cause of mesothelioma as well as other asbestos-related diseases. When cement and chrysotile mix and cured, a tough product is produced which is able to withstand the most extreme environmental hazards and weather conditions. It is also very easy to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed.

Amosite

Asbestos refers to a group of silicate fibrous minerals that are found naturally in specific types of rock formations. It is composed of six general groups: amphibole, serpentine anthophyllite, tremolite, anthophyllite, crocidolite (IARC, 1973).

Asbestos minerals consist of thin, long fibers that range in length, ranging from very fine to broad and straight to curled. These fibres can be found in nature as bundles or individual fibrils. Asbestos minerals are also found in powder form (talc) or mixed with other minerals and sold as vermiculite and talcum powder, which have been widely used in consumer products, such as baby powder cosmetics, face powder, and baby powder.

The most extensive asbestos use was during the first two-thirds period of the 20th century when it was utilized in shipbuilding, insulation, fireproofing and other construction materials. Most occupational exposures were to asbestos fibres in the air, however some workers were exposed toxic talc or vermiculite, and to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied from industry to industry, era to era and also from geographical location.

Most of the asbestos exposures that workers were exposed to was due to inhalation. However, some workers were also exposed by skin contact or through eating contaminated food. Asbestos is currently only found in the the natural weathering of mined ore and deterioration of contaminated products like insulation, car brakes and clutches and ceiling and floor tiles.

There is evidence to suggest that non-commercial amphibole fibres may also be carcinogenic. These are 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 fibers are found in mountains, sandstones and cliffs from a variety of nations.

Asbestos can enter the environment in a variety ways, such as in airborne particles. It can also be released into water or soil. This can be caused by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination in surface and ground waters is primarily due to natural weathering. However it is also caused by human activity, for instance through mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated dumping material in landfills (ATSDR 2001). The inhalation of asbestos fibres is still the primary cause of illness in people who are exposed to asbestos on a daily basis.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can infiltrate the lung which can cause serious health issues. Mesothelioma, asbestosis and other illnesses can be caused by asbestos fibres. Exposure to fibres can occur in other ways as well, for example, contact with contaminated clothing or building materials. The dangers of this kind of exposure are higher when crocidolite (the asbestos' blue form is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe and can be lodged deeper into lung tissue. It has been linked to a greater number of mesothelioma cases than any other type of asbestos.

The six main types are chrysotile and amosite. Chrysotile and amosite are the most commonly used types of asbestos and account for 95% of all commercial asbestos currently used. The other four asbestos types aren't as widespread, but they can still be present in older structures. They aren't as hazardous as amosite or chrysotile, but they can still be dangerous when mixed with other minerals or when mined near other mineral deposits, such as vermiculite and talc.

A number of studies have demonstrated an association between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos claim (http://I60bm7tc0rxec.com/Bbs/board.php?Bo_table=302&wr_id=625064) exposure and stomach. The evidence isn't unanimous. 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 other studies have reported an SMR of 1.24 (95% CI: 0.76-2.5) for workers working in chrysotile mining and mills.

The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All asbestos attorney types can cause mesothelioma, however, the risk is dependent on how much exposure, what kind of asbestos is involved, and how long the exposure lasts. IARC has declared that the best option for people 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 an illness, such as mesothelioma or other respiratory conditions it is recommended that they seek advice from their GP or NHS 111.

Amphibole

Amphibole belongs to a group of minerals that form long prism or needlelike crystals. They are a type of silicate 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 contain (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. Tetrahedrons may be separated by octahedral strips.

Amphiboles can be found in metamorphic and igneous rock. They are usually dark and hard. They are sometimes difficult to differentiate from pyroxenes because they have similar hardness and colors. They also share a corresponding cleavage pattern. However their chemistry permits an array of compositions. The chemical compositions and crystal structure of the different minerals in amphibole can be used to determine their composition.

The five types of asbestos that belong to the amphibole group include amosite, anthophyllite and chrysotile as well as crocidolite and actinolite. While the most commonly used form of asbestos is chrysotile, each variety has its own distinct characteristics. Crocidolite is the most hazardous asbestos type. It is made up of sharp fibers which are easily breathed into the lungs. Anthophyllite ranges from brown to yellowish in color and is made up of magnesium and iron. This type of stone was once used in cement-based products and insulation materials.

Amphibole minerals can be difficult to study because of their complex chemical structures and numerous substitutions. A thorough analysis of composition of amphibole minerals is a complex process that requires specialized techniques. EDS, WDS and XRD are the most popular methods for identifying amphiboles. These methods can only provide approximate identifications. For instance, these methods can't distinguish between magnesio hastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro-hornblende and pargasite.
