The Dangers of Exposure to Asbestos

Before it was banned, asbestos was used in a myriad of commercial products. According to research, asbestos compensation asbestos exposure can cause cancer as well as other health issues.

It is difficult to tell by looking at a thing if it's made of asbestos. Also, you cannot taste or smell it. Asbestos is only detectable when the material containing it is broken or drilled.

Chrysotile

At its peak, chrysotile accounted for 99percent of the asbestos made. It was widely used in industries, including construction insulation, fireproofing, as well as insulation. If workers are exposed to asbestos, they may develop mesothelioma along with other asbestos-related illnesses. Fortunately, the use of this hazardous mineral has declined significantly since mesothelioma awareness began to increase in the 1960's. However, trace amounts can still be found in the products we use in the present.

Chrysotile is safe to use provided you have a comprehensive safety and handling plan in place. It has been determined that at the current controlled exposure levels, there is no danger to those working with the substance. Inhaling airborne fibers has been linked with lung cancer and lung fibrosis. This has been confirmed both for the intensity (dose) as well as duration of exposure.

One study that examined the operation of a factory that utilized almost all chrysotile as its friction materials compared the mortality rates of this factory with national mortality rates. The study found that, after 40 years of processing low levels of chrysotile there was no significant increase in mortality in this factory.

As opposed to other forms of asbestos, chrysotile fibers tend to be smaller. They are able to enter the lungs and then enter the bloodstream. They are therefore more likely to cause health issues than fibres with longer lengths.

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

Research has revealed that amphibole asbestos like amosite or crocidolite is less likely than chrysotile in causing disease. These amphibole forms have been the primary source of mesothelioma, as well as other asbestos lawsuit-related diseases. When cement and chrysotile mix and cured, a tough, flexible product is created which is able to withstand the most extreme weather conditions and environmental hazards. It is also easy to clean up after use. Professionals can safely dispose of asbestos fibres after they have been removed.

Amosite

Asbestos is a term used to describe a class of silicate mineral fibrous that are found naturally in specific types of rock formations. It is classified into six groups including amphibole (serpentine) and the tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals are composed of long, thin fibers that range in length from fine to wide. They can be curled or straight. They are found in nature in bundles or as individual fibrils. Asbestos can also be found in a powder form (talc), or mixed with other minerals to form vermiculite or talcum powder. They are extensively used in consumer products such as baby powder, cosmetics and facial powder.

Asbestos was extensively used in the first two thirds of the 20th century for shipbuilding insulation, fireproofing and other construction materials. The majority of occupational exposures were asbestos fibres in the air, however some workers were exposed toxic talc or vermiculite as well as to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied according to industry, time and geographic location.

Asbestos exposure in the workplace is mostly caused by inhalation. However certain workers have been exposed via skin contact or through eating foods contaminated with asbestos. asbestos attorney is currently only found in the environment from the natural weathering of mined minerals and the deterioration of products contaminated with asbestos compensation (This Web site) like insulation, car brakes and clutches, as well as floor and ceiling tiles.

There is emerging evidence that amphibole fibers that are not commercially available could also be carcinogenic. These are fibers that do not have the tight weaved fibrils of amphibole or serpentine minerals but instead are loose, flexible and needle-like. These fibers are found in mountains, sandstones, and cliffs of a variety of countries.

Asbestos is absorbed into the environment mostly as airborne particles, but it can also be absorbed into water and soil. This happens both through natural (weathering and Asbestos Compensation erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination of ground and surface water is mostly due to natural weathering, but it has also been triggered by anthropogenic activities such as mining and milling demolition and dispersal asbestos-containing materials and the disposal of contaminated dumping soil in landfills (ATSDR, 2001). Airborne asbestos fibres are the main cause of illness in people exposed to asbestos during their occupation.

Crocidolite

Inhalation exposure to asbestos is the most popular way people are exposed to the harmful fibres that can then get into the lungs and cause serious health issues. Mesothelioma, asbestosis and other illnesses are caused by asbestos fibres. Exposure to asbestos fibres can occur in different ways too, such as contact with contaminated clothing or construction materials. The dangers of this kind of exposure are heightened when crocidolite, a blue form of asbestos is involved. Crocidolite fibers are less dense and more fragile and therefore easier to breathe. They also can get deeper inside lung tissue. It has been associated with more mesothelioma cancer cases than other asbestos types.

The six main types are chrysotile, amosite and chrysotile. The most commonly used forms of asbestos are chrysotile and epoxiemite, which together comprise the majority of commercial asbestos employed. The other four have not been as widely utilized but they can be present in older buildings. They are less harmful than amosite and chrysotile, however they may pose a danger when mixed with other asbestos minerals, or when mined in close proximity to other naturally occurring mineral deposits, such as talc or vermiculite.

Numerous studies have shown an association between stomach cancer and asbestos exposure. However there is no conclusive evidence. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95% 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 forms of asbestos could cause mesothelioma or other health problems, but the risks are different based on the amount of exposure people are exposed to, the kind of asbestos involved, the duration of their exposure, and the manner in the way it is inhaled or ingested. IARC has stated that the best option for individuals is to avoid all forms of asbestos. However, if a person has been exposed to asbestos in the past and suffer from a condition such as mesothelioma or other respiratory conditions it is recommended that they seek advice from their physician or NHS 111.

Amphibole

Amphiboles are groups of minerals which can create prism-like or needle-like crystals. They are an inosilicate mineral that is composed of two chains of SiO4 molecules. They have a monoclinic system of crystals, however certain crystals have an orthorhombic form. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. Double chains contain (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. The tetrahedrons can be separated from each other by octahedral sites in strips.

Amphibole minerals are found in igneous and metamorphic rocks. They are usually dark-colored and tough. They can be difficult to distinguish from pyroxenes since they share similar hardness and color. They also share a corresponding the cleavage. Their chemistry allows for a variety of compositions. The chemical compositions and crystal structures of the different mineral groups in amphibole can be used to identify them.

Amphibole asbestos is comprised of chrysotile as well as the five asbestos types amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. The most widely used form of asbestos is chrysotile, each variety is unique in its own way. The most hazardous type of asbestos, crocidolite is made up of sharp fibers that are simple to breathe into the lung. Anthophyllite is yellowish to brown in color and is composed of iron and magnesium. This kind of stone was used to create cement and insulation materials.

Amphiboles are a challenge to analyze due to their complicated chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires specialized methods. The most popular methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods only give approximate identifications. For instance, these techniques are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. These techniques also don't distinguish between ferro-hornblende and pargasite.
