The Dangers of Exposure to Asbestos

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

You cannot tell by just looking at something if it contains asbestos. Also, you cannot smell or taste it. Asbestos is only detected when materials containing it are broken, drilled, or chipped.

Chrysotile

At its height, chrysotile provided for 90% of the asbestos produced. It was used in many industries, including construction, insulation, and fireproofing. If workers are exposed to asbestos, they are likely to develop mesothelioma or asbestos attorney other asbestos-related diseases. Since the 1960s, when mesothelioma was first becoming a concern asbestos use has declined significantly. It is still present in many products we use today.

Chrysotile is safe to use provided you have a comprehensive safety and handling plan in place. People who handle chrysotile do not exposed to a significant amount of risk at the present safe exposure levels. Inhaling airborne fibres is strongly linked to lung fibrosis and lung cancer. This has been confirmed for both intensity (dose) and time of exposure.

In one study, mortality rates were compared between a factory which used almost exclusively Chrysotile for the production of friction materials and the national death rate. It was discovered that, for 40 years of preparing asbestos chrysotile in low levels of exposure there was no significant extra mortality in the factory.

Unlike some other forms of asbestos, chrysotile fibres tend to be smaller. They are able to enter the lungs and then enter the bloodstream. They are therefore more likely to cause health problems over longer fibres.

When chrysotile is mixed into cement, it is extremely difficult for the fibres to air-borne and cause health hazards. Fibre cement products are used in various parts of the world including hospitals and schools.

Research has demonstrated that amphibole asbestos like amosite or crocidolite is less likely to cause diseases. Amphibole asbestos forms have been the primary cause of mesothelioma and other asbestos-related illnesses. When chrysotile gets mixed with cement, it creates a strong, flexible building product that can withstand extreme weather conditions and other environmental hazards. It is also very easy to clean after use. Asbestos fibres can be easily removed by a professional, and then taken away.

Amosite

Asbestos is a category of fibrous silicates found in various types of rock formations. It is divided into six groups: amphibole (serpentine), Tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals are composed of long, thin fibers that vary in length from fine to broad. They can also be curled or straight. They can be found in nature in bundles or as individual fibrils. Asbestos is also found in powder form (talc), or mixed with other minerals to create talcum powder or vermiculite. They are used extensively in consumer products such as baby powder cosmetics, and even face powder.

Asbestos Attorney was extensively used in the first two thirds of the 20th century to construct construction of ships insulation, fireproofing and various other construction materials. The majority of asbestos-containing exposures to the workplace were in the air, however some workers also were exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied according to industry, time period and geographic location.

Most of the occupational exposures to asbestos claim were due to inhalation. However, some workers were also exposed via skin contact or by eating food contaminated with asbestos. Asbestos can only be found in the environment due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles automobile brakes and clutches as well as insulation.

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

Asbestos enters the environment mainly in the form of airborne particles, however it can also leach into water and soil. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination of ground and surface water is typically a result of natural weathering. However, it has also been triggered by anthropogenic activities such as mining and milling, demolition and dispersal of asbestos claim-containing materials and the disposal of contaminated dumping ground in landfills (ATSDR, 2001). Exposure to asbestos-containing airborne fibres is the most common cause of illness for people exposed to asbestos in the workplace.

Crocidolite

Exposure to asbestos through inhalation is the most common way people are exposed harmful fibres that can be absorbed into the lungs and cause serious health problems. This includes asbestosis and mesothelioma. The exposure to asbestos fibres could be triggered in other ways, like contact with contaminated clothing or building materials. This kind of exposure is more hazardous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are less dense and more fragile, making them easier to breathe in. They can also be lodged deeper within lung tissues. It has been associated with more mesothelioma cancer cases than other types of asbestos.

The six main types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. Amosite and chrysotile are the most commonly used forms of asbestos and account for 95% of the commercial asbestos in use. The other four forms haven't been as popularly used however they can be present in older buildings. They are less hazardous than amosite or chrysotile however they could still be a risk when mixed with other minerals or when mined close to other mineral deposits, such as talc and vermiculite.

A number of studies have demonstrated an connection between asbestos exposure and stomach cancer. The evidence isn't conclusive. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers, whereas others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those who work in chrysotile mines and mills.

IARC The IARC, which is the International Agency for Research on Cancer, has classified all kinds of asbestos carcinogenic. All asbestos types can cause mesothelioma but the risks vary depending on the amount of exposure, what kind of asbestos is involved and how long exposure lasts. The IARC has advised that the prevention of all asbestos types should be the highest priority because this is the best option for people. If you've been exposed to asbestos and suffer from a respiratory condition or mesothelioma, you should seek advice from your physician or NHS111.

Amphibole

Amphiboles are a grouping of minerals that can create prism-like or needle-like crystals. They are a kind of inosilicate mineral made up of double chains of SiO4 molecules. They usually have a monoclinic structure in their crystals however, some have 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 a ring of six tetrahedrons. The tetrahedrons are separated each other by strips of octahedral sites.

Amphibole minerals are found in metamorphic and igneous rocks. They are usually dark and hard. Because of their similar hardness and colour, they can be difficult for some people to differentiate from pyroxenes. They also share a corresponding design of cleavage. Their chemistry allows a wide range of compositions. The chemical compositions and crystal structures of the different minerals in amphibole can be used to identify them.

The five asbestos types in the amphibole class include amosite, anthophyllite and crocidolite. They also include actinolite. While the most frequently used form of asbestos is chrysotile, each variety has its own distinct characteristics. The most hazardous type of asbestos, crocidolite is composed of sharp fibers that are easy to breathe into the lung. Anthophyllite can be found in a brownish or yellowish hue and is made mostly of iron and magnesium. This kind of material was used to create cement and insulation materials.

Amphiboles can be difficult to study due to their complex chemical structure and numerous substitutions. Therefore, a thorough analysis of their composition requires specialized techniques. The most popular methods to identify amphiboles are EDS, WDS, and XRD. However, these methods can only give approximate identifications. For instance, these techniques can't distinguish between magnesio hastingsite and magnesio hastingsite. In addition, these techniques can not distinguish between ferro-hornblende and pargasite.
