The Dangers of Exposure to Asbestos

Asbestos was found in thousands of commercial products before it was banned. According to research, asbestos exposure can cause cancer as well as other health issues.

You cannot tell by just looking at something whether it's made of asbestos. Also, you cannot smell or taste it. It is only visible in the event that asbestos-containing products are chipped, drilled or broken.

Chrysotile

At its peak, chrysotile made up 99% of the asbestos produced. It was used by many industries, including construction insulation, fireproofing and insulation. If workers are exposed to asbestos case, they may develop mesothelioma as well as other asbestos-related illnesses. Since the 1960s, when mesothelioma became an issue, the use of asbestos has been reduced significantly. It is still found in a variety of products we use today.

Chrysotile is safe to use when you have a thorough safety and handling plan in place. Workers handling chrysotile are not exposed to an unreasonable amount of risk at current controlled exposure levels. Inhaling airborne fibers has been found to be strongly linked with lung fibrosis and lung cancer. This has been confirmed in terms of intensity (dose) as well as duration of exposure.

In one study, mortality rates were compared between a facility which used largely chlorosotile to make friction materials and the national death rate. It was found that, over the course of 40 years, processing asbestos chrysotile in low levels of exposure there was no signifi cant excess mortality in this factory.

Chrysotile fibres are usually shorter than other forms of asbestos. They can pass through the lungs and then enter the bloodstream. They are more likely to cause health issues over longer fibres.

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

Research has proven that chrysotile's risk is lower to cause illness than amphibole asbestos, such as amosite and crocidolite. These amphibole varieties are the primary source of mesothelioma as well as other asbestos-related diseases. When cement and chrysotile mix and cured, a tough product is produced that can withstand extreme environmental hazards and weather conditions. It is also easy to clean up after use. Asbestos fibers can be easily removed by a professional and safely disposed of.

Amosite

Asbestos is a category of silicate minerals with fibrous structure that are found naturally in specific kinds of rock formations. It is classified into six groups that include amphibole (serpentine) and the tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals consist of long, thin fibres that vary in length, ranging from very fine to broad and straight to curled. They are present in nature as individual fibrils, or as bundles with splaying ends called fibril matrix. Asbestos is also found in a powder form (talc) or combined with other minerals to create talcum powder or vermiculite. They are extensively used as consumer products, such as baby powder, cosmetics, and face powder.

Asbestos was used extensively in the early two-thirds of the 20th century to construct construction of ships insulation, fireproofing, insulation and various other construction materials. The majority of asbestos exposures for work were in the air, but some workers were also exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied by industry, time and geographical location.

The exposure to asbestos at work is mostly due to inhalation. However, some workers have been exposed through skin contact or eating contaminated foods. asbestos lawsuit can be found in the the natural weathering of mined minerals and deterioration of contaminated products such as insulation, car brakes, clutches, and floor and ceiling tiles.

It is becoming apparent that amphibole fibers that are not commercially available could also be carcinogenic. These fibers aren't tightly weaved like the fibrils in amphibole or serpentine, but are instead loose, flexible, and needle-like. These fibers can be found in the mountains and cliffs of several countries.

Asbestos may enter the environment in many ways, including as airborne particles. It can also leach out into soil or water. This happens both through 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 surface and ground waters is primarily due to natural weathering. However it can also be caused by human activity, asbestos for instance through mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated waste in landfills (ATSDR 2001). Airborne asbestos fibres are the main cause of illness in people exposed to asbestos during their work.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can infiltrate the lung and cause serious health issues. Mesothelioma, asbestosis and other diseases can be caused by asbestos fibres. Exposure to the fibres can occur in different ways, like contact with contaminated clothing or building materials. This type of exposure is more hazardous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are thinner and more fragile making them more palatable to breathe in. They can also lodge deeper into lung tissue. It has been linked to more mesothelioma-related cases than other types of asbestos.

The six main types of asbestos are chrysotile amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. The most common asbestos types are epoxiemite and chrysotile which together make up the majority of commercial asbestos used. The other four have not been as extensively used but they can be found in older buildings. They are not as hazardous as chrysotile and amosite, but they could pose a threat when combined with other asbestos minerals, or when mined close to other naturally occurring mineral deposits, like vermiculite or talc.

Numerous studies have proven that there is a link between stomach cancer and asbestos exposure. The evidence isn't unanimous. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95 percent CI: 0.7-3.6) for all workers exposed to asbestos while other studies have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for those who work in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma, but the risks vary depending on the amount of exposure, what type of asbestos is involved, and how long exposure lasts. IARC has declared that the best choice for people is to avoid all forms of asbestos. However, if people have been exposed to asbestos in the past and suffer from an illness such as mesothelioma, or other respiratory conditions and require advice, they should seek out guidance from their physician or NHS 111.

Amphibole

Amphiboles comprise a variety of minerals that can form prism-like and needle-like crystals. They are a type of inosilicate minerals made of double chains of SiO4 molecules. They have a monoclinic arrangement of crystals, but certain crystals have an orthorhombic form. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are composed of (Si,Al)O4 tetrahedrons that are linked in rings of six. The tetrahedrons are separated each other with octahedral strips.

Amphiboles occur in both igneous and metamorphic rock. They are typically dark and hard. Due to their similarity in hardness and color, they could be difficult for some to differentiate from the pyroxenes. They also share a corresponding the cleavage. However their chemistry allows a wide range of compositions. The various amphibole mineral groups are identified by their chemical compositions as well as crystal structures.

Amphibole asbestos includes chrysotile and the five asbestos types amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. While the most popular form of asbestos is chrysotile, each variety has its own distinct characteristics. Crocidolite is the most dangerous asbestos kind. It is composed of sharp fibers that can easily be inhaled into the lungs. Anthophyllite can be found in a brownish or yellowish hue and is comprised mostly of iron and magnesium. This variety was used to make cement and insulation materials.

Amphiboles are difficult to analyze due to their complex chemical structure and numerous substitutions. A detailed analysis of the composition of amphibole minerals is a complex process that requires specialized methods. EDS, WDS and XRD are the most widely used methods of identifying amphiboles. These methods can only provide approximate identifications. For instance, they can't distinguish between magnesio hastingsite and magnesio-hornblende. These techniques do not distinguish between ferro-hornblende and pargasite.
