The Dangers of Exposure to Asbestos

Asbestos was found in thousands of commercial products before it was banned. Research suggests that exposure to asbestos can cause cancer and other health problems.

You can't tell if something contains asbestos by looking at it and you cannot taste or smell it. asbestos lawsuit is only detectable when materials containing it are broken or drilled.

Chrysotile

At its peak, chrysotile made up for 90% of the asbestos made. It was utilized in a variety of industries, including construction insulation, fireproofing, as well as insulation. However, if workers were exposed to this toxic material, they could develop mesothelioma as well as other asbestos compensation (click the next page) related diseases. Thankfully, the use this hazardous mineral has declined significantly since mesothelioma awareness began to grow in the 1960's. It is still found in many products we use today.

Chrysotile can be safely used in the event that a thorough safety and handling plan is in place. It has been determined that at the present exposure levels, there is no undue risk to the workers working with it. The inhalation of airborne fibres has been linked with lung fibrosis and lung cancer. This has been confirmed both for the intensity (dose) as well as the duration of exposure.

One study that studied a factory that used almost exclusively chrysotile for manufacturing friction materials, compared the mortality rates of this factory with national death rates. It was found that over the course of 40 years, processing asbestos chrysotile at low levels of exposure there was no significant increase in mortality in this particular factory.

As opposed to other forms of asbestos case, chrysotile fibers tend to be smaller. They are able to penetrate the lungs and then enter the bloodstream. This makes them much more prone to cause negative effects than longer fibres.

When chrysotile is mixed with cement, it's extremely difficult for the fibres to become airborne and pose any health risk. Fibre cement products have been extensively used throughout the world, especially in buildings like hospitals and schools.

Research has proven that amphibole asbestos such as amosite or crocidolite is less likely than chrysotile in causing disease. These amphibole types have been the most common cause of mesothelioma and various asbestos-related illnesses. When chrysotile gets mixed with cement, it forms a strong, flexible building product that can withstand the most extreme weather conditions and other environmental hazards. It is also very easy to clean up after use. Professionals can safely get rid of asbestos fibres after they have been removed.

Amosite

Asbestos is a category of silicate mineral fibrous that occur naturally in certain types of rock formations. It is classified into six groups including amphibole (serpentine), tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals are composed of thin, long fibres that range in length from very fine to broad and straight to curled. They are found in nature as individual fibrils or as bundles that have splaying ends, referred to as a fibril matrix. Asbestos is also found in a powder form (talc), or combined with other minerals to make vermiculite or talcum powder. These are commonly used as consumer goods, such as baby powder, cosmetics, and even face powder.

The heaviest use of asbestos occurred in the early two-thirds of the 20th century, when it was used in insulation, shipbuilding, fireproofing and other construction materials. The majority of asbestos-containing exposures to the workplace occurred in the air, but some workers also were exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied according to industry, time, and geographic location.

The majority of occupational exposures to asbestos were because of inhalation, but certain workers were exposed through skin contact or by eating food contaminated with asbestos. Asbestos is found in the environment due to natural weathering and degrading of contaminated materials, such as ceiling and floor tiles, car brakes and clutches, and insulation.

It is becoming apparent that non-commercial amphibole fibers can also be carcinogenic. These are the fibres that are not the tightly knit fibrils of the serpentine and amphibole minerals, but instead are loose, flexible and needle-like. These fibers are found in the cliffs and mountains in a variety of countries.

Asbestos may enter the environment in many ways, including in the form of airborne particles. It can also be absorbed into soil or asbestos compensation water. This can be triggered by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is mostly due to natural weathering, but has also been caused by anthropogenic activities such as milling and mining demolition and dispersal asbestos-containing materials and the disposal of contaminated dumping ground in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary cause of disease among those exposed to asbestos in their work.

Crocidolite

Inhalation exposure is the most frequent method of exposure to asbestos law fibres. These fibres can get into the lung and cause serious health issues. These include asbestosis and mesothelioma. Exposure to fibres can occur in other ways as well like contact with contaminated clothing or construction materials. This kind of exposure is especially dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite has smaller, more fragile fibers that are easier to inhale and can lodge deeper in lung tissue. It has been linked to more mesothelioma-related cases than other asbestos types.

The six main kinds are chrysotile and amosite. The most popular forms of asbestos are epoxiemite and chrysotile which together make up the majority of commercial asbestos used. The other four types of asbestos haven't been as widely utilized but they can be present in older buildings. They are not as hazardous as chrysotile and amosite, but they may pose a danger when mixed with other asbestos minerals or when mined close to other naturally occurring mineral deposits, such as vermiculite or talc.

A number of studies have demonstrated an association between asbestos exposure and stomach cancer. Several studies have found a link between asbestos exposure and stomach. The evidence is contradictory. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95% 95% confidence interval: 0.7-3.6) for all workers exposed to asbestos as well as an SMR of 1.24 (95% of the CI = 0.76-2.5) for workers in chrysotile mines and mills.

IARC the International Agency for Research on Cancer has classified all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma but the risk is different based on the amount of exposure, what kind of asbestos is involved, and how long exposure lasts. IARC has stated that the best option for people is to avoid all forms of asbestos. If you have been exposed to asbestos and suffer from a respiratory illness or mesothelioma, you should talk to your doctor or NHS111.

Amphibole

Amphibole is a class of minerals that form long prism or needlelike crystals. They are a type of inosilicate mineral made up of two chains of SiO4 molecules. They usually have a monoclinic structure in their crystals however some may 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 that are joined in rings of six. The tetrahedrons are separated by octahedral strips.

Amphibole minerals are prevalent in igneous and metamorphic rocks. They are usually dark and hard. Due to their similarity in hardness and colour, they can be difficult for some to distinguish from Pyroxenes. They also share a similar cut. Their chemistry allows a wide variety of compositions. The various mineral groups within amphibole are identified by their chemical compositions and crystal structures.

The five types of asbestos that belong to the amphibole group include amosite, anthophyllite and chrysotile as well as crocidolite and actinolite. The most widely used asbestos compensation type is chrysotile each type is unique in its own way. The most dangerous form of asbestos, crocidolite is composed of sharp fibers that are easy to inhale into the lung. Anthophyllite can be found in a brownish or yellowish hue and is made primarily of magnesium and iron. This kind of material was used to create cement and insulation materials.

Amphibole minerals are hard to analyze due to their a complicated chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires special methods. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. These methods can only provide approximate identifications. For example, asbestos compensation these techniques cannot distinguish between magnesiohastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro-hornblende or pargasite.
