The Dangers of Exposure to Asbestos

Before it was banned asbestos was still used in a variety of commercial products. According to studies, exposure to Spearfish asbestos attorney can cause cancer and a host of other health issues.

It is impossible to determine if a product includes asbestos by looking at it, and you can't smell or taste it. It is only visible in the event that asbestos-containing products are drilled, chipped or broken.

Chrysotile

At its height, chrysotile comprised the majority of asbestos production. It was employed in many industries, including construction insulation, fireproofing and insulation. If workers were exposed to this harmful material, they could contract mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma first became an issue asbestos use has been reduced significantly. It is still found in many products we use today.

Chrysotile is safe to use if you have a comprehensive safety and handling program in place. People who handle chrysotile do not exposed to a significant amount of risk at the current controlled exposure levels. Inhaling airborne fibers has been found to be strongly linked with lung cancer and lung fibrosis. This has been proven to be true for both the intensity (dose) and the duration of exposure.

A study that looked at a factory that used almost exclusively chrysotile in the production of friction materials, compared the mortality rates of this factory with national death rates. The study found that, after 40 years of converting low levels of chrysotile, there was no significant increase in mortality in this factory.

Chrysotile fibres are usually shorter than other forms of asbestos. They are able to penetrate the lungs and 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 inhaled or to pose a health risk when mixed with cement. Fibre cement products are widely used in various parts of the world including hospitals and schools.

Research has demonstrated that amphibole effingham asbestos attorney like amosite or crocidolite is not as likely than chrysotile in causing disease. These amphibole forms have been the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile gets mixed with cement, it forms a tough, flexible building product that can withstand harsh conditions in the weather and other environmental hazards. It is also easy to clean after use. Professionals can safely get rid of asbestos fibres after they have been removed.

Amosite

Asbestos is a class of fibrous silicates that are found in certain types rock formations. It is comprised of six general groups: serpentine, wake-upcenter.com amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC 1973).

Asbestos minerals are made up of long, thin fibers that vary in length from fine to wide. They can also be straight or curled. These fibres can be found in nature in bundles or individual fibrils. Asbestos can also be found in powder form (talc), or mixed with other minerals in order to create vermiculite or talcum powder. These are widely used as consumer goods, such as baby powder cosmetics, and face powder.

The largest use of asbestos was in the first two-thirds of twentieth century in the period when it was employed in insulation, shipbuilding, fireproofing, and other construction materials. The majority of occupational exposures involved asbestos fibres that were borne in the air, but some workers were exposed to vermiculite or talc that was contaminated and also to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied from industry industry, era to era and also from geographical location.

Most asbestos-related exposures in the workplace were because of inhalation, but certain workers were exposed by skin contact or by eating food contaminated with asbestos. Asbestos is only present in the environment from the natural weathering of mined minerals and the degradation of contaminated products such as insulation, car brakes, clutches, and floor and ceiling tiles.

There is evidence to suggest that amphibole fibers that are not commercially available could also be carcinogenic. These fibers aren't weaved like the fibrils that are found in serpentine and amphibole, but are instead loose and flexible, and needle-like. These fibers can be found in the cliffs and mountains of several countries.

Asbestos can be absorbed into the environment in a variety ways, such as in airborne particles. It is also able to leach into soil or water. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination in ground and surface waters is primarily caused through natural weathering. However it can also be caused anthropogenically, such as through mining and milling of asbestos-containing materials, demolition and dispersal, and the removal of contaminated dumping material in landfills (ATSDR 2001). Airborne asbestos fibres are the primary cause of illness among people exposed to asbestos in their work.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can get into the lungs and cause serious health issues. Mesothelioma, asbestosis, and other diseases are caused by asbestos fibres. Exposure to asbestos fibers can be triggered in other ways, including contact with contaminated clothing or building materials. This kind of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is a smaller, more fragile fibers that are easy to inhale and can lodge deeper in lung tissue. It has been linked to a higher number of mesothelioma related cases than any other type of asbestos.

The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite anthophyllite, and actinolite. The most popular forms of asbestos are epoxiemite and chrysotile which together comprise the majority of commercial asbestos employed. The other four asbestos types are not as prevalent, but could still be found in older structures. They are less hazardous than amosite or chrysotile but still pose a threat when combined with other minerals or when mined close to other mineral deposits such as talc and vermiculite.

Numerous studies have revealed that there is a link between stomach cancer and asbestos exposure. However there is no conclusive evidence. Some researchers have cited a SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers, and 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.

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 problems, but the risks are different based on the amount of exposure people are exposed to, the type of asbestos used, the duration of their exposure and the way in the way that it is breathed in or consumed. The IARC has recommended that avoiding all forms of asbestos should be the top priority, as this is the most safe option for individuals. However, if people have been exposed to asbestos in the past and are suffering from an illness such as mesothelioma and other respiratory conditions it is recommended that they seek advice from their GP or NHS 111.

Amphibole

Amphiboles are a grouping of minerals that can form needle-like or prism-like crystals. They are an inosilicate mineral that is composed of two chains of SiO4 molecules. They are a monoclinic system of crystals, however certain crystals have an orthorhombic form. 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. The tetrahedrons can be separated from one another by octahedral sites that are surrounded by strips.

Amphiboles are present in both igneous and metamorphic rock. They are usually dark and hard. Due to their similarity of hardness and color, they may be difficult for some to distinguish from the pyroxenes. They also share a similar pattern of cleavage. Their chemistry allows for a range of compositions. The different mineral groups within amphibole are identified by their chemical compositions and crystal structures.

The five asbestos types belonging to the amphibole family are amosite, anthophyllite and crocidolite. They also include actinolite. Each type of asbestos has its own distinct properties. The most dangerous form of asbestos, crocidolite is made up of sharp fibers that are easy to inhale into the lung. Anthophyllite can range from yellow to brown in color and is made up of magnesium and iron. The variety was used previously in products such as cement and insulation materials.

Amphiboles can be difficult to study due to their complex chemical structure and the numerous substitutions. Therefore, a detailed analysis of their composition requires special methods. EDS, WDS and XRD are the most commonly used methods of identifying amphiboles. These methods are only able to provide approximate identifications. For instance, these techniques can't distinguish between magnesio hornblende and magnesio hastingsite. These techniques also cannot differentiate between ferro-hornblende or pargasite.
