The Dangers of Exposure to Asbestos

Asbestos was found in thousands of commercial products before it was banned. According to studies, exposure to asbestos can cause cancer as well as other health issues.

It is difficult to tell if something is asbestos-containing by looking at it and you are unable to smell or taste it. It can only be found when asbestos-containing materials are drilled, chipped or broken.

Chrysotile

At its height, chrysotile provided for 99percent of the asbestos that was produced. It was used in many industries like construction insulation, fireproofing, and insulation. If workers are exposed to asbestos lawsuit, they are likely to develop mesothelioma as well as other asbestos-related diseases. Fortunately, the use this toxic mineral has decreased drastically since mesothelioma awareness started to increase in the 1960's. However, trace amounts are still found in common products that we use today.

Chrysotile is safe to use in the event that you have a complete safety and handling program in place. It has been proven that at the current controlled exposure levels, there isn't an undue risk to the workers working with it. Inhaling airborne fibers is strongly linked to lung cancer and lung fibrosis. This has been confirmed both for the intensity (dose) as well as duration of exposure.

In one study mortality rates were compared between a factory that primarily used Chrysotile in the production of friction materials and the national death rate. It was discovered that, for 40 years of preparing asbestos chrysotile at a low level of exposure There was no significant additional mortality in this factory.

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

When chrysotile is mixed with cement, it is very difficult for the fibres to air-borne and pose health risks. Fibre cement products are used extensively throughout the world particularly in structures such as schools and hospitals.

Research has revealed that amphibole asbestos, like amosite or crocidolite is not as likely than chrysotile to cause disease. These amphibole varieties are the main source of mesothelioma as well as other asbestos-related diseases. When cement and chrysotile are mixed, a durable, flexible product is created that is able to withstand extreme weather conditions and environmental hazards. It is also very easy to clean up after use. Asbestos fibres can easily be removed by a professional and then safely taken away.

Amosite

Asbestos refers to a group of silicate minerals with fibrous structure that naturally occur in certain types of rock formations. It is comprised of six general groups: amphibole, serpentine anthophyllite, tremolite, anthophyllite, crocidolite (IARC, 1973).

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

Asbestos was extensively used in the first two thirds of the 20th century to construct construction of ships, insulation, fireproofing, and various other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, however some workers were also exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied by the type of industry, the time period and geographic location.

Most asbestos exposures that workers were exposed to was due to inhalation, but certain workers were exposed through skin contact or through eating contaminated food. Asbestos is only present in the environment from the natural weathering of mined minerals and the deterioration of products contaminated with asbestos like insulation, car brakes, clutches, and floor and ceiling tiles.

It is becoming evident that non-commercial amphibole fibers can also be carcinogenic. These are fibres that are not the tightly knit fibrils of the amphibole or serpentine minerals but instead are loose, flexible and needle-like. These fibres can be found in mountain sandstones, cliffs and sandstones in a variety of countries.

Asbestos is able to enter the environment in a variety ways, including as airborne particles. It can also be absorbed into water or soil. This can be caused by both natural (weathering of asbestos-bearing rock) and anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination in ground and surface water is mostly caused by natural weathering. However it is also caused by humans, 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). Asbestos fibres that are emitted from the air are the most significant reason for illness among those who are exposed to it during their job.

Crocidolite

Exposure to asbestos through inhalation is the most common way people are exposed to dangerous fibres, which can then get into the lungs and cause serious health problems. These include mesothelioma and asbestosis. Exposure to Asbestos Attorney fibres can occur in other ways as well, such as contact with contaminated clothing or construction materials. This kind of exposure is more hazardous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are smaller and more fragile making them more palatable to inhale. They also can get deeper inside lung tissue. It has been associated with a higher number of mesothelioma-related cases than any other form of asbestos.

The six primary types are chrysotile, amosite and chrysotile. Chrysotile and amosite are among the most commonly used types of asbestos, and comprise 95 percent of all commercial asbestos in use. The other four forms haven't been as popularly used, but they may still be found in older buildings. They are not as hazardous as amosite and chrysotile, however they could be a risk when mixed with other asbestos minerals or when mined close to other naturally occurring mineral deposits, such as vermiculite or talc.

Numerous studies have revealed an association between asbestos exposure and stomach cancer. A number of studies have confirmed that asbestos exposure is linked to stomach. However the evidence isn't conclusive. Some researchers have cited an overall SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for those who work in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classed all asbestos types as carcinogenic. All types of asbestos can cause mesothelioma as well as other health problems, but the risk is dependent on the amount of exposure that people are exposed to, the kind of asbestos involved as well as the length of their exposure and the way in which it is inhaled or consumed. IARC has declared that the best option for individuals is to stay clear of all types of asbestos. If you have been exposed to asbestos and suffer from a respiratory condition or mesothelioma, you should see your physician or NHS111.

Amphibole

Amphiboles comprise a variety of minerals that may form needle-like or prism-like crystals. They are a type of inosilicate mineral made up of double chains of molecules of SiO4. They have a monoclinic system of crystals, but some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 tetrahedrons that are linked in rings of six. Tetrahedrons may be separated by octahedral strips.

Amphiboles are present in metamorphic and igneous rock. They are usually dark and hard. They can be difficult to distinguish from pyroxenes due to their similar hardness and colors. They also have a similar the cleavage. However their chemistry allows a wide range of compositions. The chemical compositions and crystal structures of the various mineral groups found in amphibole may be used to determine their composition.

The five types of asbestos compensation that belong to the amphibole group include chrysotile, anthophyllite, amosite and crocidolite. They also include actinolite. While the most popular form of asbestos is chrysotile; each has its own distinct characteristics. The most dangerous type of asbestos, crocidolite, is made up of sharp fibers that are simple to breathe into the lungs. Anthophyllite comes in a brownish-to yellowish hue and is comprised primarily of magnesium and iron. This kind of material was used to create cement and insulation materials.

Amphibole minerals are difficult to study because of their complex chemical structures and numerous substitutions. Therefore, a detailed analysis of their composition requires specialized methods. EDS, WDS and asbestos Attorney XRD are the most widely used methods of identifying amphiboles. However, these methods only provide approximate identifications. These techniques, for example, cannot distinguish between magnesio hastingsite and magnesio hastingsite. These techniques do not differentiate between ferro-hornblende or pargasite.
