The Dangers of Exposure to Asbestos

Asbestos was used in a variety of commercial products before it was banned. Research has shown that exposure to asbestos can cause cancer and other health problems.

You cannot tell if something includes asbestos simply by looking at it and you cannot taste or smell it. It is only discovered in the event that asbestos-containing products are drilled, chipped or broken.

Chrysotile

At its height, chrysotile provided for 99percent of the asbestos produced. It was used by many industries including construction, fireproofing, and insulation. If workers are exposed to grosse pointe farms asbestos lawsuit, they can develop mesothelioma along with other asbestos-related diseases. Since the 1960s, when mesothelioma first became an issue the use of asbestos has decreased significantly. It is still present in many products we use in the present.

Chrysotile can be safely used in the event that a thorough safety and handling plan is put into place. People who handle chrysotile do not exposed to an unreasonable amount of risk at the present safe exposure levels. Lung fibrosis, lung cancer and mesothelioma are all associated with breathing in airborne respirable fibres. This has been confirmed for both the intensity (dose) and duration of exposure.

In one study, mortality rates were compared between a factory that used a large proportion of Chrysotile in the production of friction materials and national death rates. The study concluded that, after 40 years of manufacturing low levels of chrysotile there was no significant increase in mortality rates at this facility.

Chrysotile fibres tend to be shorter than other types of asbestos. They are able to enter the lungs, and then pass through the bloodstream. They are therefore more likely to cause health issues than fibres with longer lengths.

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

Research has shown that chrysotile is less likely to cause illness than amphibole asbestos such as crocidolite and amosite. Amphibole types like these are the main cause of mesothelioma and other asbestos-related diseases. When chrysotile is mixed in with cement, it creates an extremely durable and flexible building product that can withstand extreme conditions in the weather and other environmental dangers. It is also easy to clean up after use. Professionals can safely remove asbestos fibres once they have been removed.

Amosite

Asbestos is a class of fibrous silicates found in certain types rock formations. It is classified into six groups which include amphibole (serpentine), tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals comprise long, thin fibers that vary in length from fine to broad. They can also be curled or straight. They are present in nature in the form of individual fibrils or bundles with splaying edges called a fibril matrix. Asbestos minerals are also found in powder form (talc) or mixed with other minerals and sold as vermiculite and talcum powder that are widely used in consumer products, such as baby powder cosmetics, face powder and baby powder.

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 in the air, however some workers were exposed to toxic talc or vermiculite as well as to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied according to the type of industry, the time period, and geographic location.

Most asbestos-related exposures in the workplace were caused by inhalation, however certain workers were exposed by skin contact or through eating contaminated food. Asbestos is now only found in the air due to the natural weathering of mined ore and the deterioration of products contaminated with asbestos like insulation, car brakes and clutches, and floor and ceiling tiles.

There is emerging evidence that amphibole fibres from non-commercial sources could also be carcinogenic. These are fibres that don't form the tightly weaved fibrils of amphibole and serpentine minerals, but instead are loose, flexible and needle-like. These fibers can be found in the cliffs, mountains and sandstones of many countries.

Asbestos can be absorbed into the environment in a variety ways, including through airborne particles. It can also leach out into water or soil. This can be due to both natural (weathering of asbestos-bearing rock) and anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of surface and ground water is mostly due to natural weathering, however it has also been caused by anthropogenic activities such as milling and mining demolition and dispersal of asbestos-containing material and the disposal of contaminated dumping soils in landfills (ATSDR 2001). Inhalation exposure to asbestos fibres remains the main cause of illness in people exposed to it occupationally.

Crocidolite

Inhalation exposure is the most frequent method of exposure to asbestos fibres. These fibres can get into the lungs and cause serious health issues. This includes asbestosis and mesothelioma. Exposure to asbestos fibers can also take place in other ways, like contact with contaminated clothing or building materials. This type of exposure is especially dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite is smaller and more fragile fibers, which are easier to breathe in and can get deeper into lung tissue. It has been linked to a greater number of mesothelioma related cases than any other type of asbestos.

The six major types of asbestos are chrysotile, amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. Amosite and chrysotile are the most commonly used types of asbestos and account for 95 percent of all commercial asbestos in use. The other four fairview Asbestos lawyer types are not as prevalent, but could still be present in older structures. They are less hazardous than amosite and chrysotile, but they may pose a danger when combined with other asbestos minerals or when mined in close proximity to other naturally occurring mineral deposits, like talc or vermiculite.

Numerous studies have proven an association between stomach cancer and asbestos exposure. However there is no conclusive evidence. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, and others have reported an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for workers in chrysotile mines or chrysotile mills.

The International Agency for Research on Cancer (IARC) 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 type of asbestos is involved and how long exposure lasts. The IARC has advised that avoid all forms of asbestos is the best option since this is the best option for those who are exposed. If you've been exposed in the past to asbestos and suffer from a respiratory illness or mesothelioma condition, then you should consult your GP or Vimeo NHS111.

Amphibole

Amphiboles are groups of minerals that form prism-like or needle-like crystals. They are a type of silicate mineral composed of double chains of SiO4 molecules. They have a monoclinic system of crystals, however some have an orthorhombic shape. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are composed of (Si,Al)O4 tetrahedrons that are linked in rings of six. The tetrahedrons are separated from each other by octahedral sites that are surrounded by strips.

Amphiboles occur in both igneous and metamorphic rock. They are usually dark and hard. Because of their similar hardness and color, they could be difficult for some to distinguish from pyroxenes. They also share a similar cleavage pattern. Their chemistry can allow for a range of compositions. The chemical compositions and crystal structure of the various mineral groups found in amphibole may be used to identify them.

Amphibole asbestos comprises chrysotile and the five asbestos types amosite anthophyllite (crocidolite), amosite (actinolite) and amosite. While the most popular asbestos type is chrysotile, each variety is unique in its own way. The most harmful type of asbestos, crocidolite, is made up of sharp fibers that are simple to inhale into the lung. Anthophyllite comes in a brownish-to yellowish hue and is made mostly of iron and magnesium. This type was used to make cement and insulation materials.

Amphibole minerals are difficult to analyze because they have a an intricate chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires specialized techniques. The most commonly used methods for identifying amphiboles are EDS, WDS, and XRD. However, these methods only give approximate identifications. For instance, these techniques cannot distinguish between magnesiohastingsite and magnesio-hornblende. In addition, these techniques can not distinguish between ferro hornblende and pargasite.
