The Dangers of Exposure to Asbestos

Before it was banned asbestos was used in a myriad of commercial products. According to studies, exposure to asbestos can cause cancer as well as other health issues.

You cannot tell by just looking at something whether it is made up of asbestos. Also, you cannot smell or taste it. Asbestos can only be identified when the materials that contain it are broken or drilled.

Chrysotile

At its height, chrysotile comprised up 99% of the asbestos produced. It was widely used in industries including construction, insulation, and fireproofing. If workers were exposed to the toxic material, they could contract mesothelioma and other asbestos-related diseases. Since the 1960s, when mesothelioma first became a problem the use of asbestos has been reduced significantly. It is still found in many products we use today.

Chrysotile is safe to use when you have a thorough safety and handling plan in place. Personnel handling chrysotile aren't exposed to an undue amount of risk based on the current controlled exposure levels. Lung cancer, lung fibrosis and mesothelioma have been strongly linked to breathing airborne respirable fibres. This has been confirmed for intensity (dose) as well as duration of exposure.

One study that looked into a facility that used nearly exclusively chrysotile in the production of friction materials compared mortality rates in this facility with national death rates. It was found that, for the 40 years of processing asbestos chrysotile at low levels of exposure, there was no significant increase in mortality in this particular factory.

Chrysotile fibres tend to be shorter than other forms of asbestos. They are able to enter the lungs and then enter the bloodstream. This makes them much more likely to cause health effects than fibrils with a longer length.

It is extremely difficult for chrysotile fibres to be in the air or pose a health risk when mixed with cement. Fibre cement products are used in many parts of the world including hospitals and schools.

Research has shown that chrysotile is less likely to cause illness than amphibole asbestos, such as crocidolite and amosite. These amphibole forms have been the primary cause of mesothelioma as well as other charlottesville asbestos attorney-related diseases. When chrysotile gets mixed with cement, it forms a tough, flexible building product that is able to withstand severe weather conditions and other environmental dangers. It is also very easy to clean up after use. Professionals can safely get rid of asbestos fibres after they have been removed.

Amosite

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

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

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

The exposure to asbestos in the workplace is mainly because of inhalation. However, some workers have been exposed by contact with their skin or through eating foods contaminated with asbestos. lemoore asbestos lawyer is found in the air due to natural weathering and degradation of contaminated products, such as ceiling and floor tiles as well as car brakes and clutches, and insulation.

It is becoming clear that non-commercial amphibole fibers could also be carcinogenic. These are fibres that don't form the tightly knit fibrils of the serpentine and amphibole minerals, but instead are flexible, loose and needle-like. These fibres are found in the mountains and cliffs of several countries.

Asbestos may enter the environment in a variety of ways, including in the form of airborne particles. It can also be absorbed into soil or water. This can be triggered by both natural (weathering of asbestos-bearing rock) as well as 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 asbestos-containing materials as well as the disposal of contaminated dumping soil in landfills (ATSDR, 2001). The inhalation of asbestos fibres remains the main cause of illness among people exposed to it occupationally.

Crocidolite

Inhalation exposure to asbestos is the most common way people are exposed harmful fibres that can then be inhaled and cause serious health issues. Mesothelioma as well as asbestosis and other diseases can be caused by asbestos fibres. Exposure to fibres can occur in different ways too including contact with contaminated clothing, or building materials. This type of exposure is particularly dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are thinner and more fragile which makes them more difficult to breathe in. They can also lodge deeper inside lung tissues. It has been associated with more mesothelioma cancer cases than other types of asbestos.

The six main types of Bluffton 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 comprise 95 percent of all commercial asbestos that is used. The other four have not been as widely used however they can be present in older buildings. They are less hazardous than amosite or chrysotile but still be dangerous when mixed with other minerals or when mined close to other mineral deposits like vermiculite and talc.

A number of studies have demonstrated an association between asbestos exposure and stomach cancer. Several studies have found a link between asbestos exposure and stomach. However the evidence is not conclusive. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, and others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those working in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All types of asbestos can cause mesothelioma as well as other health problems, but the risk is dependent on the amount of exposure that people are exposed to, the kind of asbestos used and the duration of their exposure and the manner in which it is breathed in or ingested. IARC has stated that the best choice for individuals is to stay clear of all types of asbestos. If you've been exposed to asbestos and are suffering from a respiratory condition or mesothelioma condition, then you should talk to your doctor or NHS111.

Amphibole

Amphiboles comprise a variety of minerals which can form prism-like or needle-like crystals. They are an inosilicate mineral composed of double chains of SiO4 molecules. They are a monoclinic system of crystals, but some exhibit an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 Tetrahedrons that are joined in rings of six. Tetrahedrons can be separated by strips of octahedral site.

Amphiboles can be found in both igneous and metamorphic rock. They are usually dark-colored and tough. Because of their similar hardness and color, they can be difficult for some people to differentiate from the pyroxenes. They also share a corresponding the cleavage pattern. However their chemistry permits a wide range of compositions. The different amphibole mineral groups are identified by their chemical compositions and crystal structures.

The five asbestos types belonging to the amphibole family are amosite, anthophyllite and chrysotile and Bluffton Asbestos crocidolite. They also include actinolite. While the most popular form of asbestos is chrysotile, each variety has its own unique characteristics. The most dangerous type of asbestos, crocidolite is composed of sharp fibers that are easy to breathe into the lungs. Anthophyllite is a brownish to yellowish color and is composed mostly of iron and magnesium. This type was used to make cement and insulation materials.

Amphibole minerals are difficult to study because of their an intricate chemical structure and many substitutions. Therefore, a thorough analysis of their composition requires specialized methods. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods only provide approximate identifications. For instance, these techniques, cannot distinguish between magnesio-hornblende and hastingsite. These techniques also don't differentiate between ferro-hornblende or pargasite.
