The Dangers of Exposure to Asbestos

Asbestos was used in thousands of commercial products before it was banned. Studies have shown that exposure to asbestos can cause cancer as well as other health issues.

It is impossible to determine if a product contains asbestos by looking at it and you won't be able to taste or smell it. It is only discovered when asbestos-containing materials are drilled, chipped or broken.

Chrysotile

At its peak, chrysotile accounted for 95% of the asbestos produced. It was used by many industries including construction insulation, fireproofing, as well as insulation. If workers are exposed to asbestos, they could develop mesothelioma or other asbestos-related illnesses. Fortunately, the use this hazardous mineral has declined drastically since mesothelioma awareness started to grow in the 1960's. It is still present in many products we use today.

Chrysotile can be used in a safe manner when a thorough safety and handling plan is in place. Chrysotile handling workers aren't exposed to an undue amount of risk at the current safe exposure levels. The inhalation of airborne fibres is strongly linked to lung fibrosis and lung cancer. This has been confirmed for both the intensity (dose) and duration of exposure.

One study that studied the operation of a factory that utilized almost exclusively chrysotile for manufacturing friction materials, compared the mortality rates of this factory with national mortality rates. The study concluded that, after 40 years of manufacturing 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 smaller. They can pass through the lungs and then enter the bloodstream. They are more likely to cause health problems 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 have been extensively used all over the world, especially in buildings like hospitals and schools.

Studies have shown that chrysotile is less prone to cause illness than amphibole asbestos, such as amosite and crocidolite. These amphibole varieties are the main source of mesothelioma as well as other asbestos-related diseases. When the cement and chrysotile are combined and cured, a tough and flexible material is created that can withstand extreme environmental hazards and weather conditions. It is also simple to clean after use. washington asbestos attorney fibers can be easily removed by a professional, and then taken away.

Amosite

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

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

Asbestos was widely used during the first two thirds of the 20th century to construct construction of ships insulation, fireproofing and various other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, but certain workers were also exposed to Asbestos Litigation-bearing rock fragments and vermiculite that was contaminated. Exposures varied from industry to industry, era to era and geographic location.

The exposure to asbestos at work is mostly caused by inhalation. However certain workers have been exposed through skin contact or by eating food items contaminated with asbestos. Asbestos is currently only found in the environment due to the natural weathering of mined ore and the degrading of contaminated materials like insulation, car brakes and clutches, as well as floor and ceiling tiles.

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

Asbestos is absorbed into the environment mostly in the form of airborne particles, however it also leaches into water and soil. This can be due to both natural (weathering of asbestos-bearing rock) and anthropogenic causes (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is typically a result of natural weathering, but it has also been triggered by anthropogenic activities such as milling and mining, demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated dumping soils in landfills (ATSDR, 2001). Exposure to asbestos-containing airborne fibres is still the primary cause of illness in people exposed to asbestos in the workplace.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can get into the lung, causing serious health problems. Mesothelioma as well as asbestosis and other illnesses can be caused by asbestos fibres. Exposure to asbestos fibers can be triggered in other ways, such as contact with contaminated clothing or building materials. The dangers of this kind of exposure are higher when crocidolite, the asbestos that is blue, is involved. Crocidolite fibers are less dense and more fragile which makes them more difficult to inhale. They also can get deeper into lung tissue. It has been linked to a larger number of mesothelioma-related cancers than any other type of asbestos.

The six main kinds are chrysotile and amosite. The most commonly used asbestos types are epoxiemite as well as chrysotile which together make up the majority of commercial asbestos used. The other four types haven't been as popularly used however they can be present in older buildings. They are less harmful than amosite and chrysotile. However, asbestos litigation they can pose a risk when combined with other asbestos minerals or when mined close to other mineral deposits, like talc or vermiculite.

Numerous studies have revealed an connection between asbestos exposure and stomach cancer. Several studies have found a link between asbestos exposure and stomach. However the evidence isn't conclusive. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% of the time CI: 0.7-3.6) for all asbestos-related workers and others have reported an SMR of 1.24 (95% C.I. 0.76-2.5) for those working in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All asbestos types can cause mesothelioma, however the risks differ based on how much exposure, what kind of asbestos is involved and how long the exposure lasts. IARC has declared that the best option for individuals is to avoid all forms of asbestos. If you've been exposed to asbestos and are suffering from a respiratory disorder or mesothelioma, you should consult your GP or NHS111.

Amphibole

Amphiboles are a collection of minerals that can form needle-like or prism-like crystals. They are a type of inosilicate mineral composed of double chains of molecules of SiO4. They usually have a monoclinic structure in their crystals, although some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains comprise (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. The tetrahedrons are separated from each other by octahedral sites in strips.

Amphiboles can be found in metamorphic and Asbestos litigation igneous rock. They are usually dark and hard. They are sometimes difficult to differentiate from pyroxenes because they have similar hardness and colors. They also have a comparable Cleavage. Their chemistry can allow for a range of compositions. The various minerals within amphibole can be identified by their chemical compositions as well as crystal structures.

Amphibole asbestos consists of chrysotile, and the five asbestos types: amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. While the most popular form of asbestos is chrysotile; each is unique in its own way. The most dangerous form of asbestos, crocidolite, is made up of sharp fibers that are simple to breathe into the lungs. Anthophyllite ranges from brown to yellowish in color and is composed of iron and magnesium. This kind of stone was used to create cement and insulation materials.

Amphiboles are difficult to analyze due to their complex chemical structure and the numerous substitutions. Therefore, a thorough analysis of their composition requires special techniques. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. However, these methods only provide approximate identifications. For instance, these techniques cannot distinguish between magnesiohastingsite and magnesio-hornblende. These techniques also cannot differentiate between ferro-hornblende or pargasite.
