The Dangers of Exposure to asbestos litigation (www.koreafurniture.com said in a blog post)

Before it was banned asbestos was used in a myriad of commercial products. According to research, exposure to asbestos can cause cancer and a host of other health issues.

It is impossible to determine if a product is asbestos-containing simply by looking at it and you can't smell or taste it. Asbestos can only be detected when the materials that contain it are broken, drilled, or chipped.

Chrysotile

At its peak, chrysotile made up for 99percent of the asbestos that was produced. It was utilized in a variety of industries, including construction insulation, fireproofing, and construction. If workers were exposed to this toxic substance, they could develop mesothelioma or other asbestos related diseases. Fortunately, the use this toxic mineral has decreased significantly since awareness of mesothelioma began to increase in the 1960's. It is still present in many of the products we use today.

Chrysotile is safe to use in the event that you have a complete safety and handling plan in place. It has been found that at the current controlled exposure levels, there is no unneeded risk to the people handling it. Lung cancer, lung fibrosis and mesothelioma have all been found to be strongly linked to breathing airborne respirable fibres. This has been confirmed both in terms of intensity (dose) as well as the duration of exposure.

One study that examined an industrial facility that used almost all chrysotile as its friction materials compared the mortality rates of this factory with national mortality rates. It was found that for the 40 years of processing asbestos chrysotile at a low level of exposure there was no significant excess mortality in this factory.

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

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

Research has revealed that chrysotile is less likely to cause illness than amphibole asbestos like amosite and crocidolite. These amphibole varieties are the main source of mesothelioma as well as other asbestos-related diseases. When chrysotile gets mixed with cement, it forms a tough, flexible building product that is able to withstand severe conditions in the weather and other environmental hazards. It is also very easy to clean after use. Asbestos fibres are easily removed by a professional and taken away.

Amosite

Asbestos refers to a set of silicate fibrous minerals that occur naturally in certain types of rock formations. It is divided into six groups including amphibole (serpentine), Tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.

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

The greatest asbestos use occurred during 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 asbestos-related exposures in the workplace occurred in the air, however some workers were also exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied according to the type of industry, the time period, and geographic location.

The majority of asbestos exposures that workers were exposed to was due to inhalation, but some workers were also exposed through contact with skin or through eating contaminated food. Asbestos is only present in the the natural weathering of mined minerals and the deterioration of products contaminated with asbestos like insulation, car brakes, clutches as well as ceiling and floor tiles.

There is emerging evidence that non-commercial amphibole fibers could also be carcinogenic. These fibers aren't weaved like the fibrils that are found in amphibole and serpentine they are loose as well as flexible and needle-like. They can be found in mountains, sandstones, and cliffs of many countries.

Asbestos is absorbed into the environment mostly in the form of airborne particles, however it also leaches into soil and water. This can be caused by both natural (weathering of asbestos-bearing rocks) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground waters is primarily caused through natural weathering. However it can also be caused anthropogenically, such as by the milling and mining of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping material in landfills (ATSDR 2001). Airborne asbestos fibres are the main cause of illness in people exposed to asbestos in their occupation.

Crocidolite

Inhalation exposure is the most popular method of exposure to asbestos fibres. The fibres can penetrate the lungs and cause serious health issues. These include asbestosis and mesothelioma. Exposure to asbestos fibres can occur in a variety of ways, for example, contact with contaminated clothing or materials. This type of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is smaller and more fragile fibers that are easy to breathe in and may lodge deeper in lung tissue. It has been associated with a higher number of mesothelioma related cases than any other type of asbestos.

The main types are chrysotile and amosite. The most well-known asbestos types are epoxiemite and chrysotile which together comprise 95% all commercial asbestos employed. The other four asbestos types are not as well-known, but can still be present in older structures. They aren't as hazardous as amosite or chrysotile but still be a risk when mixed with other minerals or when mined near other naturally occurring mineral deposits such as talc and vermiculite.

Numerous studies have demonstrated the connection between stomach cancer and asbestos exposure. The evidence isn't unanimous. Certain researchers have reported an 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% C.I. 0.76-2.5) for workers working in chrysotile mining and mills.

The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All types of asbestos can cause mesothelioma and other health issues, but the risks are different based on the amount of exposure that people are exposed to, the type of asbestos legal involved as well as the duration of exposure and the manner in the way that it is breathed in or consumed. The IARC has advised that abstaining from all asbestos forms is the most important thing to do since this is the most safe option for those who are exposed. If you've been exposed to asbestos and suffer from a respiratory condition or mesothelioma then you should talk to your doctor or NHS111.

Amphibole

Amphibole is one of the minerals that form long prism or needle-like crystals. They are a kind of inosilicate mineral made up of two chains of molecules of SiO4. They have a monoclinic structure of crystals, but 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 can be separated from one another by strips of octahedral sites.

Amphibole minerals are found in metamorphic and igneous rocks. They are usually dark and hard. They can be difficult to differentiate from pyroxenes since they share similar hardness and colors. They also have a comparable cut. Their chemistry allows a wide variety of compositions. The various minerals within amphibole can be identified by their chemical compositions as well as crystal structures.

Amphibole asbestos consists of chrysotile, and the five asbestos types: amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. Each kind of asbestos has its own unique properties. Crocidolite is the most dangerous asbestos kind. It is made up of sharp fibers that can be easily inhaled into the lung. Anthophyllite ranges from brown to yellowish in color and is made up of magnesium and iron. This variety was once used in products such as cement and insulation materials.

Amphiboles are a challenge to analyze because of their complex chemical structure and the numerous substitutions. A thorough analysis of the composition of amphibole minerals is a complex process that requires specialized methods. EDS, WDS and XRD are the most commonly used methods of identifying amphiboles. However, these methods can only provide approximate identifications. For instance, they cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques also do not distinguish between ferro-hornblende as well as pargasite.
