The Dangers of Exposure to asbestos Attorney

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

It is not possible to tell by simply taking a look at something if it contains asbestos. It is also impossible to smell or taste it. Asbestos can only be detected when materials containing it are broken, drilled, or chipped.

Chrysotile

At its peak, chrysotile accounted for 90% of the asbestos that was produced. It was widely used in industries such as construction insulation, fireproofing, as well as insulation. If workers were exposed to this toxic substance, they could develop mesothelioma and other asbestos-related diseases. Fortunately, the use of this hazardous mineral has declined dramatically since mesothelioma awareness began 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 you have a thorough safety and handling program in place. It has been found that at the present exposure levels, there is no danger to those who handle the substance. The inhalation of airborne particles is strongly linked to lung fibrosis and lung cancer. This has been confirmed both for the intensity (dose) as in the time of exposure.

In one study mortality rates were compared between a facility which used largely chrysotile in the manufacture of friction materials and national death rates. The study revealed that after 40 years of processing at low levels of chrysotile, there was no significant increase in mortality rates at this facility.

Chrysotile fibres tend to be shorter than other forms of asbestos. They are able to enter the lungs and enter the bloodstream. They are more likely to cause health issues than fibres that are longer.

When chrysotile gets mixed with cement, it is extremely difficult for the fibres to breathe and pose any health risks. Fibre cement products have been used extensively throughout the world particularly in structures like hospitals and schools.

Research has proven that amphibole asbestos, such as amosite or crocidolite is not as likely than chrysotile in causing disease. Amphibole asbestos types have been the most common cause of mesothelioma and various asbestos-related illnesses. When chrysotile is combined with cement, it creates a tough, flexible building product that can withstand extreme conditions in the weather and other environmental hazards. It is also easy to clean up after use. Asbestos fibres can be easily removed by a professional and taken away.

Amosite

Asbestos refers to a set of silicate mineral fibrous that occur naturally in certain kinds of rock formations. It consists of six general groups: serpentine, amphibole anthophyllite, tremolite and crocidolite (IARC 1973).

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

The most extensive asbestos use occurred during the early two-thirds of the twentieth century in the period when it was employed in insulation, shipbuilding, fireproofing and other construction materials. Most occupational exposures were to asbestos fibres borne by air, but some workers were exposed to vermiculite and talc that had been contaminated, and to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied by the industry, time frame and geographical location.

Asbestos exposure at work is mostly because of inhalation. However, some workers have been exposed through skin contact or through eating foods contaminated with asbestos. Asbestos is currently only found in the the natural weathering of mined minerals and the deterioration of products contaminated with asbestos such as insulation, car brakes and clutches, and 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 interwoven fibrils that are found in the amphibole and serpentine minerals but instead are loose, flexible and needle-like. These fibres are found in the mountains and cliffs from a variety of countries.

Asbestos can be found in the environment in the form of airborne particles, however it can also be absorbed into soil and water. This can be triggered by both natural (weathering of asbestos-bearing rocks) and anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination in ground and surface water is mostly caused by natural weathering. However it can also be caused by anthropogeny, such as through the mining and milling of asbestos-containing materials demolition and dispersal and the disposal of contaminated waste in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary cause of illness in people exposed to asbestos claim in their work.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. The fibres can penetrate the lungs and cause serious health issues. These include asbestosis and mesothelioma. The exposure to asbestos fibres could be experienced in other ways, including contact with contaminated clothing or building materials. The risks of exposure are higher when crocidolite which is the asbestos in the blue form, is involved. Crocidolite is smaller and more fragile fibers, which are easier to inhale and can lodge deeper in lung tissue. It has been linked to a higher number of mesothelioma cases than any other type of asbestos.

The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite and actinolite. The most commonly used asbestos types are epoxiemite as well as chrysotile which together comprise the majority of commercial asbestos used. The other four asbestos types are not as common, but may still be present in older structures. They are less harmful than chrysotile and amosite, but they can pose a risk when mixed with other asbestos minerals or mined in close proximity to other naturally occurring mineral deposits, such as vermiculite or talc.

Numerous studies have revealed the connection between stomach cancer and asbestos exposure. However, the evidence is contradictory. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, whereas others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those working in chrysotile mines or chrysotile mills.

IARC The IARC, which is the International Agency for Research on Cancer, has classified all kinds of asbestos as carcinogenic. All asbestos types can cause mesothelioma however the risks differ based on the amount of exposure, what kind of asbestos is involved, and the length of time that exposure lasts. IARC has stated that the best choice for people is to avoid all forms of asbestos. If you have been exposed to asbestos and suffer from a respiratory disorder or mesothelioma then you should see your physician or NHS111.

Amphibole

Amphibole is a group of minerals that form long prisms or needlelike crystals. They are a type inosilicate mineral made up of two chains of molecules of SiO4. They typically possess a monoclinic crystal system however, some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are made up of (Si,Al)O4 Tetrahedrons, which are connected in rings of six. The tetrahedrons can be separated from one another with octahedral strips.

Amphiboles are found in metamorphic and igneous rock. They are usually dark-colored and are hard. Due to their similarity of hardness and color, they could be difficult for some to differentiate from the pyroxenes. They also have a similar cut. However their chemistry permits an array of compositions. The chemical compositions and crystal structure of the different minerals in amphibole can be used to identify them.

The five types of asbestos 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 type has its own distinct characteristics. The most dangerous form of asbestos, crocidolite is composed of sharp fibers that are simple to inhale into the lung. Anthophyllite is a brownish to yellowish color and is made mostly of iron and magnesium. This variety was used to make cement and insulation materials.

Amphibole minerals are challenging to analyze because they have a an intricate chemical structure and numerous substitutions. A thorough analysis of composition of amphibole minerals requires specialized techniques. The most commonly used methods of identifying amphiboles include EDS, WDS, and XRD. These methods can only provide approximate identifications. For instance, these methods cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques also cannot distinguish between ferro-hornblende and.
