The Dangers of Exposure to Asbestos

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

You cannot tell by just looking at something whether it is made of asbestos. Neither can you taste or smell it. derby asbestos lawsuit can only be identified when the material containing it is broken, drilled, or chipped.

Chrysotile

At its peak, chrysotile made up for 99percent of the asbestos produced. It was utilized in a variety of industries, including construction, insulation, and fireproofing. Unfortunately, if workers were exposed to this harmful material, they could contract mesothelioma or Colby asbestos Lawyer other hartwell asbestos related diseases. Fortunately, the use this toxic mineral has decreased dramatically since mesothelioma awareness began to spread in the 1960's. It is still found in many of the products we use today.

Chrysotile can be used safely in the event that a thorough safety and handling plan is put in place. Workers handling chrysotile are not exposed to an unreasonable amount of risk at the current limit of exposure. The inhalation of airborne fibres is strongly linked to lung cancer and lung fibrosis. This has been confirmed for both intensity (dose) and duration of exposure.

One study that examined a facility that used nearly exclusively chrysotile to manufacture friction materials, compared mortality rates in this factory with national death rates. It was concluded that for the 40 years of processing asbestos chrysotile at low levels of exposure there was no signifi cant excess mortality in this factory.

Chrysotile fibres are usually shorter than other types of asbestos. They can pass through the lungs, and enter the bloodstream. They are therefore more likely to cause health problems than longer fibres.

It is very difficult for chrysotile fibres be in the air or pose a health risk when mixed with cement. The fibre cement products are used extensively throughout the world particularly in buildings such as schools and hospitals.

Research has shown that amphibole asbestos, like amosite or crocidolite is not as likely than chrysotile to cause diseases. These amphibole forms have been the primary cause of mesothelioma and various asbestos-related illnesses. When chrysotile is mixed in with cement, it creates a strong, flexible building product that can withstand harsh weather conditions and other environmental hazards. It is also easy to clean after use. Asbestos fibres can easily be removed by a professional, and then eliminated.

Amosite

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

Asbestos minerals are made up of thin, long fibers that range in length from fine to wide. They can be curled or straight. These fibres are found in nature as individual fibrils or as bundles with splaying ends called fibril matrix. Asbestos minerals can also be found as a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite and are used in consumer products, such as baby powder cosmetics, face powder and other.

The most extensive use of asbestos occurred in the early two-thirds of the 20th century where it was used in shipbuilding, insulation, fireproofing, and other construction materials. Most occupational exposures were asbestos fibres that were borne in the air, but certain workers were exposed to vermiculite or talc that was contaminated and also to fragments of asbestos-bearing rocks (ATSDR, 2001). Exposures varied from industry to industry, from era to and geographic location.

Most of the asbestos exposures at work were due to inhalation. However, certain workers were exposed via skin contact or by eating food contaminated with asbestos. Asbestos can be found in the environment from natural weathering of mined ores and deterioration of contaminated products such as insulation, car brakes, clutches and ceiling and floor tiles.

It is becoming evident that non-commercial amphibole fibers could also be carcinogenic. These fibers aren't tightly woven like the fibrils found in serpentine and amphibole, but are instead loose, flexible, and needle-like. These fibers can be found in the mountains and cliffs from a variety of countries.

Asbestos is able to enter the environment in many ways, such as in airborne particles. It is also able to leach into soil or water. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing wastes in landfill sites) sources. Asbestos contamination of surface and ground waters is primarily caused by natural weathering. However it is also caused by anthropogeny, such as by the milling and mining of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Inhalation exposure to airborne asbestos fibres is still the primary cause of illness for people who are exposed to asbestos on a daily basis.

Crocidolite

Exposure to asbestos through inhalation is the most frequent way people are exposed to dangerous fibres, which can then get into the lungs and cause serious health problems. Mesothelioma, asbestosis, and other illnesses are caused by asbestos fibres. Exposure to asbestos fibres can occur in different ways too including contact with contaminated clothing or materials. The dangers of exposure are greater when crocidolite, the asbestos' blue form is involved. Crocidolite fibers are less dense and more fragile making them more palatable to breathe. They can also lodge deeper into lung tissue. It has been associated with a higher number of mesothelioma related cases than any other type of asbestos.

The six major types of colby asbestos lawyer are chrysotile amosite as well as epoxiemite. Tremolite is anthophyllite, and actinolite. The most popular forms of asbestos are epoxiemite and chrysotile which together comprise 95% all commercial asbestos used. The other four asbestos types aren't as common, but may still be found in older structures. They are not as dangerous as amosite or chrysotile, but they can still be a danger when combined with other minerals or when mined close to other mineral deposits such as vermiculite and talc.

Numerous studies have demonstrated the connection between stomach cancer and asbestos exposure. The evidence is not conclusive. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95% of the time CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95 percent 95% CI: 0.76-2.5) for workers in chrysotile mines and mills.

IARC, the International Agency for Research on Cancer, has classified all kinds of asbestos as carcinogenic. All forms of asbestos could cause mesothelioma as well as other health problems, but the risks vary according to the amount of exposure that people are exposed to, the kind of asbestos used, the duration of their exposure and the method by the way it is inhaled or consumed. IARC has declared that the best option for individuals is to avoid all forms of asbestos. However, if someone has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma and other respiratory ailments They should seek advice from their physician or NHS 111.

Amphibole

Amphiboles comprise a variety of minerals that create prism-like or needle-like crystals. They are a type of silicate mineral made up of double chains of SiO4 molecules. They have a monoclinic system of crystals, however some exhibit an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. Double chains contain (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. Tetrahedrons may be separated by strips of octahedral sites.

Amphibole minerals are prevalent in metamorphic and igneous rocks. They are typically dark and hard. Due to their similarity of hardness and color, they may be difficult for some people to distinguish from pyroxenes. They also share a similar the cleavage. However their chemistry permits an array of compositions. The chemical compositions and crystal structure of the different mineral groups found in amphibole may be used to determine their composition.

Amphibole asbestos comprises chrysotile and the five asbestos types amosite anthophyllite (crocidolite), amosite (actinolite) and amosite. While the most commonly used asbestos type is chrysotile. Each variety has distinct characteristics. Crocidolite is the most hazardous asbestos type. It contains sharp fibers that are easily breathed into the lung. Anthophyllite is brown to yellowish in color and is made up of iron and magnesium. This variety was once used in products like cement and insulation materials.

Amphibole minerals are hard to analyze due to their a complicated chemical structure and a variety of substitutions. A thorough analysis of composition of amphibole minerals requires specialized techniques. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. These methods are only able to provide approximate identifications. For instance, they cannot differentiate between magnesio-hastingsite and magnesio-hornblende. Moreover, these techniques do not distinguish between ferro hornblende and pargasite.
