The Dangers of Exposure to Asbestos

Before it was banned asbestos was used in a myriad of commercial products. Research suggests that exposure to asbestos can cause cancer and other health issues.

It is impossible to tell just by looking at something if it contains asbestos. It is also impossible to smell or taste it. Asbestos can only be identified when the materials that contain it are broken, drilled, or chipped.

Chrysotile

At its height, chrysotile comprised up 99% of the asbestos production. It was used in many industries including construction, insulation, and fireproofing. If workers were exposed to this harmful material, they may develop mesothelioma or other asbestos related diseases. Fortunately, the use this dangerous mineral has decreased significantly since awareness of mesothelioma began to grow in the 1960's. It is still present in many products we use today.

Chrysotile can be used safely in the event that a thorough safety and handling plan is in place. It has been discovered that, at today's controlled exposure levels, there is no danger to those handling it. Inhaling airborne fibers has been found to be strongly linked with lung cancer and lung fibrosis. This has been confirmed for intensity (dose) as in the time of exposure.

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

In contrast to other forms of asbestos, chrysotile fibers tend to be smaller. They can enter the lungs and enter the bloodstream. They are more likely to cause health issues than longer fibres.

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

Research has revealed that amphibole asbestos like crocidolite or amosite is less likely than chrysotile in causing disease. These amphibole kinds have been the main source of mesothelioma, as well as other asbestos-related diseases. When chrysotile is combined with cement, it forms a strong, flexible construction product that can withstand the most extreme weather conditions and other environmental hazards. It is also easy to clean after use. Asbestos fibres are easily removed by a professional and removed.

Amosite

Asbestos is a category of fibrous silicates that are found in a variety of rock formations. It is classified into six groups which include amphibole (serpentine) and tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals comprise long, thin fibers that vary in length from fine to wide. They can also be straight or curled. These fibres can be found in nature in bundles or individual fibrils. Asbestos is also found in a powder form (talc) or mixed with other minerals to make talcum powder or vermiculite. They are used extensively as consumer goods, such as baby powder, cosmetics and face powder.

The greatest use of asbestos was in the first two-thirds period of the twentieth century in the period when it was employed in shipbuilding, insulation, fireproofing, and other construction materials. The majority of asbestos-related exposures in the workplace were in the air, but some workers were also exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied according to industry, time and geographical location.

Exposure to asbestos at work is mostly due to inhalation. However there are workers who have been exposed via skin contact or by eating food items contaminated with asbestos. Asbestos is found in the natural environment due to natural weathering and degrading of products that are contaminated like ceiling and floor tiles, car brakes and clutches, and insulation.

It is becoming increasingly apparent that non-commercial amphibole fibers could also be carcinogenic. These fibers aren't tightly woven like the fibrils found in amphibole and serpentine they are loose as well as flexible and needle-like. These fibers can be found in the mountains and cliffs of several countries.

Asbestos is absorbed into the environment mostly as airborne particles, but it also leaches into water and soil. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and the anthropogenic (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination of ground and surface water is largely associated with natural weathering, but has also been caused by human activities such as mining and milling demolition and dispersal asbestos-containing materials, and the removal of contaminated dumping soils in landfills (ATSDR, 2001). Asbestos fibres that are emitted from the air are the main reason for illness among those who are exposed to it during their work.

Crocidolite

Exposure to asbestos through inhalation is the most common way people are exposed to dangerous fibres, which can be absorbed into the lungs and cause serious health issues. Mesothelioma, asbestosis, and other diseases are all caused by asbestos fibres. Exposure to the fibres can occur in different ways, such as contact with contaminated clothes or building materials. The risks of exposure are heightened when crocidolite, a asbestos compensation in the blue form is involved. Crocidolite is a smaller, more fragile fibers, which are easier to breathe in and may lodge deeper into lung tissue. It has been linked to a higher number of mesothelioma related cases than any other type of asbestos.

The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite anthophyllite and actinolite. Chrysotile and amosite are the most commonly used forms of asbestos. They comprise 95% of the commercial asbestos that is used. The other four have not been as extensively used however they can be present in older buildings. They aren't as hazardous as amosite or chrysotile, but they can still be a risk when mixed with other minerals or when mined near other naturally occurring mineral deposits like vermiculite and talc.

Many studies have discovered an association between asbestos exposure and stomach cancer. However there is no conclusive evidence. Some researchers have cited an overall SMR (standardized mortality ratio) of 1.5 (95 percent range of CI: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for Asbestos law workers working in chrysotile mining and mills.

IARC The IARC, which is the International Agency for Research on Cancer, has classified all forms of asbestos law; Going in Xn Oy 2b 33di 2g 89d 2d 53r 6oyika, as carcinogenic. All forms of asbestos could cause mesothelioma or other health issues, but the risk is dependent on the amount of exposure that individuals are exposed to, the kind of asbestos used, the duration of their exposure and the manner in the way it is inhaled or ingested. IARC has declared that the best choice for people is to stay clear of all types of asbestos. If you've been exposed to asbestos and are suffering from a respiratory disorder or mesothelioma, then you should see your physician or NHS111.

Amphibole

Amphiboles are groups of minerals which can create prism-like or needle-like crystals. They are an inosilicate mineral made up 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 contain (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. Tetrahedrons are distinguished from one another by octahedral sites that are surrounded by strips.

Amphiboles occur in both igneous and metamorphic rock. They are usually dark and hard. Due to their similarity in strength and color, they can be difficult for some to differentiate from pyroxenes. They also share a similar cleavage. Their chemistry allows a wide variety of compositions. The chemical compositions and crystal structure of the different mineral groups in amphibole can be used to determine their composition.

Amphibole asbestos consists of chrysotile, and the five asbestos types amosite anthophyllite (crocidolite), amosite (actinolite), asbestos Law and amosite. While the most frequently used asbestos type is chrysotile; each has distinct characteristics. Crocidolite is the most dangerous asbestos kind. It is composed of sharp fibers that are easily inhaled into the lungs. Anthophyllite ranges from brown to yellowish in color and is composed of magnesium and iron. 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 a variety of substitutions. A detailed analysis of the composition of amphibole minerals requires special methods. The most commonly used methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods only provide approximate identifications. For instance, these techniques, cannot distinguish between magnesio hornblende and hastingsite. These techniques also do not differentiate between ferro-hornblende or pargasite.
