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 asbestos can cause cancer as well as other health issues.

It is difficult to tell by looking at something whether it contains asbestos. It is also impossible to taste or smell it. It can only be found when the asbestos-containing materials are chipped, drilled or broken.

Chrysotile

At its peak, chrysotile accounted for 99% of the asbestos lawsuit that was produced. It was widely used in industries including construction, fireproofing, and insulation. However, if workers were exposed to this harmful material, they could develop mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma became a problem, the use of asbestos has been reduced significantly. It is still found in a variety of 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. Lung cancer, lung fibrosis and mesothelioma are all linked to breathing airborne respirable fibres. 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 manufacture of friction materials and national death rates. It was discovered that, over the course of 40 years, processing asbestos chrysotile at a low level of exposure there was no significant excess mortality in this factory.

Chrysotile fibres are typically shorter than other forms of asbestos. They are able to enter the lungs and enter the bloodstream. They are more likely to cause health problems than longer fibres.

It is extremely difficult for chrysotile fibres to be a threat to the air or pose any health risk when mixed with cement. Fibre cement products are used in a variety of locations around the world, including schools and hospitals.

Research has revealed that amphibole asbestos such as amosite, crocidolite, or crocidolite, is less likely to cause disease. These amphibole forms have been the primary cause of mesothelioma and various asbestos-related diseases. When cement and chrysotile mix together, a strong and flexible product is created that is able to withstand extreme weather conditions and environmental hazards. It is also very easy to clean after use. Asbestos fibres can be easily removed by a professional and eliminated.

Amosite

Asbestos is a grouping of fibrous silicates found in various types of rock formations. It is comprised of six general groups: amphibole, serpentine, tremolite, anthophyllite and crocidolite (IARC, 1973).

Asbestos minerals are composed of thin, long fibers that range in length, ranging from very fine to broad and straight to curled. These fibers are found in nature as individual fibrils or bundles with splaying ends called a fibril matrix. Asbestos can also be found in a powder form (talc) or combined with other minerals to make talcum powder or vermiculite. They are extensively used as consumer products, like baby powder, cosmetics and facial powder.

Asbestos was heavily used in the first two thirds of the 20th century to construct shipbuilding as well as insulation, fireproofing and various other construction materials. The majority of asbestos-containing exposures to the workplace occurred in the air, however some workers also were exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied according to industry, time, and geographic location.

Exposure to asbestos at work is mostly due to inhalation. However there have been instances of workers being exposed via skin contact or through eating foods contaminated with asbestos. Asbestos can be found in the natural weathering of mined ores and the deterioration of products contaminated with asbestos like insulation, car brakes, asbestos litigation clutches, as well as floor and ceiling tiles.

It is becoming apparent that non-commercial amphibole fibres may also be carcinogenic. These fibres are not tightly woven like the fibrils found in serpentine and amphibole, they are loose as well as flexible and needle-like. These fibers are found in the mountains and cliffs of several countries.

Asbestos is able to enter the environment in a variety of ways, such as in airborne particles. It can also leach out into soil or water. This can be due to both natural (weathering of asbestos-bearing rocks) and anthropogenic causes (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination in surface and ground waters is primarily due to natural weathering. However it can also be caused anthropogenically, such as through mining and milling of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the most significant cause of disease among those exposed to asbestos during their occupation.

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 issues. Mesothelioma, asbestosis and other diseases are all caused by asbestos litigation (Read More Here) fibres. Exposure to fibres can occur in other ways as well like contact with contaminated clothing, or Asbestos Litigation building materials. This type of exposure is more dangerous when crocidolite (the blue asbestos legal form) is involved. Crocidolite fibers are smaller and more fragile and therefore easier to breathe in. They can also be lodged deeper into lung tissues. It has been linked to more mesothelioma cases than other asbestos law types.

The main types are chrysotile and amosite. Amosite and chrysotile are the most commonly used forms of asbestos. They comprise 95 percent of all asbestos used in commercial construction. The other four have not been as popularly used however they can be present in older buildings. They are not as dangerous as amosite or chrysotile, but they can still be a danger when combined with other minerals or when mined near other mineral deposits, such as vermiculite and talc.

Many studies have discovered an association between exposure to asbestos and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. However, the evidence is contradictory. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% 95% confidence interval: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95 percent CI: 0.76-2.5) for workers in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All kinds of asbestos can cause mesothelioma or other health issues, however the risk is dependent on the amount of exposure individuals are exposed to, the type of asbestos used, the duration of their exposure, and the manner in which it is inhaled or consumed. IARC has stated that the best option for people is to stay clear of all forms of asbestos. If you have been exposed in the past to asbestos and are suffering from a respiratory condition or mesothelioma then you should talk to your doctor or NHS111.

Amphibole

Amphiboles are a collection of minerals which can form prism-like or needle-like crystals. They are a type inosilicate mineral composed of double chains of SiO4 molecules. They have a monoclinic arrangement of crystals, however some have an orthorhombic shape. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains comprise (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. The tetrahedrons are separated from one another by octahedral sites in strips.

Amphiboles can be found in metamorphic and igneous rock. They are usually dark and hard. They can be difficult to distinguish from pyroxenes since they share similar hardness and color. They also share a similar pattern of cleavage. Their chemistry can allow for a 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 in the amphibole class include amosite, anthophyllite and crocidolite. They also include actinolite. Each type of asbestos has distinct characteristics. Crocidolite is considered to be the most hazardous asbestos type. It is composed of sharp fibers that can be easily inhaled into the lungs. Anthophyllite can range from yellow to brown in color and is composed of iron and magnesium. This type of stone was once used in cement and insulation materials.

Amphibole minerals are difficult to study because of their complex chemical structures and a variety of substitutions. A thorough analysis of the composition of amphibole mineral requires specialized methods. The most common methods of identifying amphiboles include EDS, WDS, and XRD. These methods can only provide approximate identifications. For instance, these techniques can't distinguish between magnesio hastingsite and magnesio-hornblende. These techniques also do not distinguish between ferro-hornblende and.
