The Dangers of Exposure to Asbestos

Before it was banned asbestos was used in thousands commercial products. According to studies, exposure to asbestos can cause cancer and many other health problems.

You cannot tell by just looking at something whether it contains asbestos. It is also impossible to smell or taste it. Asbestos is only detectable when the materials that contain it are broken or drilled.

Chrysotile

At its height, chrysotile was responsible for 99% of the yucaipa asbestos lawyer created. It was used in many industries like construction insulation, fireproofing, and insulation. If workers were exposed to this toxic material, they could contract mesothelioma and other asbestos-related diseases. Since the 1960s, when mesothelioma became an issue asbestos use has declined significantly. However, traces of it are still found in products that we use today.

Chrysotile can be safely used when a thorough safety and handling plan is put in place. Chrysotile handling workers aren't exposed to an undue amount of risk at the current limit of exposure. The inhalation of airborne fibres has been found to be strongly linked with lung cancer and lung fibrosis. This has been proven for the intensity (dose) as well as the duration of exposure.

In one study mortality rates were compared between a factory that primarily used chlorosotile to make friction materials and the national death rate. The study revealed that after 40 years of converting low levels of chrysotile, there was no significant rise in mortality rates in this factory.

In contrast to other forms of asbestos, chrysotile fibres tend to be shorter. They can pass through the lungs and then enter the bloodstream. This makes them much more likely to cause ill-health effects than longer fibres.

It is extremely difficult for chrysotile fibrous to be inhaled or to pose a health risk when mixed with cement. Fibre cement products are widely used in various parts of the world including hospitals and schools.

Research has revealed that chrysotile has a lower chance to cause disease than amphibole asbestos like crocidolite and amosite. These amphibole varieties are the primary source of mesothelioma as well as other asbestos-related diseases. When chrysotile is mixed in with cement, it forms a strong, flexible building product that can withstand extreme weather conditions and other environmental hazards. It is also easy to clean after use. Asbestos fibres can be easily removed by a professional, and then eliminated.

Amosite

Asbestos refers to a set of silicate minerals with fibrous structure which are found naturally in a variety of kinds of rock formations. It consists of six general groups: serpentine, amphibole anthophyllite, tremolite and crocidolite (IARC 1973).

Asbestos minerals consist of thin, long fibers that range in length from fine to broad. They can also be curled or straight. These fibres can be found in nature in bundles or individual fibrils. Asbestos minerals can also 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 baby powder.

The heaviest asbestos use occurred during the first two-thirds of twentieth century when it was utilized in shipbuilding, insulation, fireproofing and other construction materials. The majority of occupational exposures involved 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 from industry industry, era to and even geographical location.

The majority of asbestos exposures at work were due to inhalation. However, certain workers were exposed through skin contact or through eating contaminated food. Asbestos is only found in the air due to natural weathering and degrading of contaminated materials like ceiling and floor tiles automobile brakes and clutches, and insulation.

There is growing evidence that non-commercial amphibole fibers could also be carcinogenic. These are fibres that do not have the tight weaved fibrils of amphibole and serpentine minerals but instead are loose, Vimeo flexible and needle-like. These fibers can be found in the mountains and cliffs of several countries.

Asbestos enters the environment mainly as airborne particles, but it can also be absorbed into water and soil. This is caused by both natural (weathering of asbestos-bearing rock) and anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground waters is primarily caused through natural weathering. However it is also caused by human activity, for instance by the milling and mining of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Airborne asbestos fibres are the most significant cause of illness among people exposed to asbestos during their occupation.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can enter the lung and cause serious health problems. Mesothelioma and asbestosis as well as other illnesses can be caused by asbestos fibres. The exposure to asbestos can happen in other ways as well like contact with contaminated clothing or materials. This type of exposure is especially dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite is a smaller, more fragile fibers that are more easy to inhale and can lodge deeper into lung tissue. It has been associated with a higher number of mesothelioma cases than any other form of asbestos.

The six main types of hurricane asbestos lawsuit are chrysotile, amosite as well as epoxiemite. Tremolite is anthophyllite, and actinolite. Amosite and chrysotile are the most frequently used types of asbestos and make up 95% of the commercial asbestos currently used. The other four have not been as popularly used however they can be found in older buildings. They are less dangerous than amosite and chrysotile, but they can pose a risk when combined with other asbestos minerals or when mined close 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 reported an SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for Vimeo those working in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma but the risk is different based on the amount of exposure is taken, what type of asbestos is involved, and how long the exposure lasts. IARC has stated that the best choice for people is to avoid all forms of asbestos. However, if someone has been exposed to asbestos in the past and suffer from an illness, such as mesothelioma or any other respiratory illnesses it is recommended that they seek advice from their GP or NHS 111.

Amphibole

Amphibole is a class of minerals that form long prism or needle-like crystals. They are an inosilicate mineral made up of double chains of SiO4 molecules. They typically have a monoclinic crystal system but some also have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are composed of (Si,Al)O4 Tetrahedrons which are connected in rings of six. The tetrahedrons can be separated by octahedral strips.

Amphibole minerals are common in igneous and metamorphic rocks. They are typically dark and hard. They can be difficult to differentiate from pyroxenes since they share similar hardness and color. They also share a similar the cleavage. Their chemistry permits a wide range of compositions. The different minerals within amphibole can be identified by their chemical compositions as well as crystal structures.

The five types of asbestos belonging to the amphibole family are chrysotile, anthophyllite, amosite and crocidolite. They also include actinolite. The most widely used asbestos type is chrysotile, each variety has its own unique characteristics. The most dangerous form of asbestos, crocidolite is made up of sharp fibers that are simple to inhale into the lungs. Anthophyllite can be found in a brownish or yellowish hue and is made primarily of magnesium and iron. This type was used to make cement and insulation materials.

Amphiboles are difficult to analyze due to their complex chemical structure and numerous substitutions. Therefore, Vimeo a thorough analysis of their composition requires specialized methods. The most commonly used methods of identifying amphiboles include EDS, WDS, and XRD. However, these methods can only provide approximate identifications. These methods, for instance, cannot distinguish between magnesio hastingsite and magnesio hastingsite. These techniques also don't distinguish between ferro-hornblende as well as pargasite.
