The Dangers of Exposure to Asbestos

Asbestos was a component in thousands of commercial products prior to when it was banned. According to research, exposure to asbestos can cause cancer as well as other health issues.

It is impossible to tell just by looking at a thing if it contains asbestos. You cannot smell or taste it. Asbestos can only be identified when the material containing it is broken, drilled, or chipped.

Chrysotile

At its peak, chrysotile accounted for the majority of the wheaton asbestos lawyer production. It was used in many industries, including construction insulation, fireproofing, and insulation. Unfortunately, if workers were exposed to this toxic substance, they could develop mesothelioma as well as other asbestos related diseases. Fortunately, the use this hazardous mineral has declined significantly since mesothelioma awareness began to spread in the 1960's. However, trace amounts of it remain in many of 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 found that, at today's controlled exposure levels, there isn't an danger to the people handling the substance. The inhalation of airborne fibres has been strongly associated with 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 facility that used a large proportion of Chrysotile in the production of friction materials and the national death rate. It was found that for 40 years of preparing asbestos chrysotile in low levels of exposure there was no signifi cant increase in mortality in this particular factory.

In contrast to other forms of asbestos, chrysotile fibers tend to be shorter. They can penetrate the lungs and then enter the bloodstream. This makes them much more prone to causing health effects than fibrils with a longer length.

It is very difficult for chrysotile fibres to be in the air or pose a health risk when mixed with cement. Fibre cement products have been extensively used throughout the world particularly in buildings such as schools and hospitals.

Studies have shown that chrysotile is less prone to cause illness than amphibole asbestos like amosite and crocidolite. These amphibole types are the main cause of mesothelioma, and other asbestos-related diseases. When chrysotile gets mixed with cement, it forms an extremely durable and flexible building product that is able to withstand severe conditions in the weather and other environmental dangers. It is also easy to clean after use. Asbestos fibres can easily be removed by a professional and taken away.

Amosite

Asbestos is a term used to describe a class of silicate fibrous minerals which are found naturally in a variety of types of rock formations. It is classified into six groups which include amphibole (serpentine), Tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals comprise thin, long fibers that vary in length from fine to broad. They can also be curled or straight. These fibers are found in nature in bundles, or as individual fibrils. Asbestos minerals can be found as a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder, which have been widely used in consumer products like baby powder cosmetics, face powder and other.

Asbestos was widely used during the first two thirds of the 20th century for shipbuilding insulation, fireproofing and other construction materials. The majority of occupational exposures were asbestos fibres that were borne in the air, but some workers were exposed to contaminated vermiculite or talc, and to fragments of asbestos-bearing rocks (ATSDR 2001). 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. However, certain workers were exposed through skin contact or through eating contaminated food. Asbestos can be found in the natural environment due to natural weathering and degrading of contaminated materials like ceiling and floor tiles as well as car brakes and clutches, and insulation.

It is becoming evident that amphibole fibers that are not commercially available could also be carcinogenic. They are not tightly woven like the fibrils found in amphibole and serpentine, they are loose, flexible, and needle-like. They can be found in mountains, sandstones and cliffs in a variety of countries.

Asbestos gets into the environment primarily as airborne particles, but it can also be absorbed into water and soil. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination in surface and ground waters is primarily caused by natural weathering. However, it has also been caused anthropogenically, such as through milling and mining of asbestos-containing materials, Clayton Asbestos Attorney demolition and dispersal, and the removal of contaminated dumping material in landfills (ATSDR 2001). Airborne asbestos fibres are the most significant reason for illness among those exposed to it in their work.

Crocidolite

Inhalation exposure is the most commonly used method of exposure to asbestos fibres. These fibres can infiltrate the lungs and cause serious health problems. This includes asbestosis and mesothelioma. Exposure to fibres can occur in other ways, too, such as contact with contaminated clothing, or building materials. The risks of exposure are heightened when crocidolite, the blue form of asbestos is involved. Crocidolite fibers are less dense and more fragile, making them easier to inhale. They can also get deeper into lung tissues. It has been associated with a higher number of mesothelioma-related cancers 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 and chrysotile, which together make up the majority of commercial asbestos employed. The other four asbestos types are not as common, but may still be found in older structures. They aren't as hazardous as amosite or chrysotile however they could still be dangerous when mixed with other minerals, or when mined near other mineral deposits such as talc and vermiculite.

Numerous studies have shown that there is a link between stomach cancer and asbestos exposure. The evidence is contradictory. Some researchers have cited a SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all clayton asbestos attorney workers, and others have reported an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those working in chrysotile mills and mines.

IARC The IARC, also known as the International Agency for Research on Cancer, has classified all kinds of asbestos as carcinogenic. All kinds of asbestos can cause mesothelioma and other health issues, but the risks are different based on the amount of exposure individuals are exposed to, the kind of asbestos involved, the duration of their exposure and the way in the way it is inhaled or consumed. IARC has declared that the best option for people is to avoid 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 and other respiratory conditions it is recommended that they seek advice from their physician or NHS 111.

Amphibole

Amphiboles comprise a variety of minerals that form prism-like or needle-like crystals. They are an inosilicate mineral that is composed of two chains of SiO4 molecules. They usually have a monoclinic crystal system, although 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 which are connected in rings of six. The tetrahedrons are separated one another with octahedral strips.

Amphiboles can be found in both igneous and metamorphic rock. They are typically dark-colored and hard. Because of their similar hardness and colour, they can be difficult for some to distinguish from Pyroxenes. They also share a similar the cleavage pattern. Their chemistry can allow for a range of compositions. The chemical compositions and crystal structures of the different mineral groups found in amphibole may be used to determine their composition.

Amphibole asbestos consists of chrysotile, and the five types of meadville asbestos attorney: amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. Each type of arkansas asbestos has its own unique properties. The most hazardous type of asbestos, crocidolite, is made up of sharp fibers that are simple to breathe into the lung. Anthophyllite ranges from brown to yellowish in color and is made up of magnesium and iron. This variety was once used in cement and insulation materials.

Amphibole minerals are difficult to study because of their a complicated chemical structure and a variety of substitutions. Therefore, a detailed analysis of their composition requires specialized methods. EDS, WDS and XRD are the most common methods of identifying amphiboles. These methods are only able to provide approximate identifications. For instance, these techniques can't distinguish between magnesio hastingsite and magnesio-hornblende. In addition, these techniques can not distinguish between ferro-hornblende or pargasite.
