The Dangers of Exposure to Asbestos
Asbestos was used in a variety of commercial products before it was banned. According to studies, exposure to asbestos can cause cancer as well as other health problems.
It is impossible to tell just by looking at a thing if it contains asbestos. Neither can you taste or smell it. Asbestos is only detected when the material containing it is broken or drilled.
Chrysotile
At its peak, chrysotile made up 99% of asbestos production. It was used in many industries, including construction insulation, fireproofing, and insulation. However, if workers were exposed for long periods to this toxic substance, they could develop mesothelioma, as well as other asbestos-related diseases. Thankfully, the use of this dangerous mineral has decreased dramatically since mesothelioma awareness began to grow in the 1960's. However, trace amounts of it can still be found in many of the products we use today.
Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. It has been proven that, at today's controlled exposure levels, there is no danger to the people handling it. The inhalation of airborne particles has been linked with lung cancer and lung fibrosis. This has been proven for both intensity (dose) and time span of exposure.
In one study, mortality rates were compared between a manufacturing facility that primarily used Chrysotile in the production of friction materials and the national death rate. It was found that, for the 40 years of processing chrysotile asbestos at low levels of exposure, there was no significant excess mortality in this factory.
Chrysotile fibres are typically shorter than other types of asbestos. They can pass through the lungs, and enter the bloodstream. They are more likely to cause health issues than longer fibres.
When chrysotile gets mixed with cement, it is extremely difficult for the fibres to become airborne and pose any health risk. Fibre cement products are extensively used throughout the world particularly in buildings such as schools and hospitals.
Research has demonstrated that amphibole asbestos, such as crocidolite or amosite is less likely than chrysotile to cause diseases. Amphibole asbestos types have been the most common source of mesothelioma, as well as other asbestos-related diseases. When chrysotile is combined with cement, it forms a tough, flexible building product that can withstand harsh weather conditions and other environmental hazards. It is also simple to clean after use. Asbestos fibres can easily be removed by a professional and disposed of.
Amosite
Asbestos is a class of fibrous silicates found in certain types rock formations. It is composed of six general groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC, 1973).
Asbestos minerals are made up of thin, long fibres that range in length from extremely thin to broad and straight to curled. These fibers are found in nature in bundles or as individual fibrils. Asbestos minerals can also be found as a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder that are widely used in consumer products such as baby powder cosmetics, face powder and baby powder.
Asbestos was widely used during the early two-thirds of the 20th century for shipbuilding, insulation, fireproofing, and various other construction materials. The majority of asbestos exposures for work occurred in the air, however some workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied according to the type of industry, the time period and geographic location.
Most of the asbestos exposures that workers were exposed to was due to inhalation. However, some workers were also exposed by skin contact or through eating contaminated food. Asbestos is only present in the environment from natural weathering of mined ores and the degrading of contaminated materials like insulation, car brakes, clutches as well as ceiling and floor tiles.
There is growing evidence that non-commercial amphibole fibres may also be carcinogenic. These are the fibres that don't form the tightly woven fibrils of the amphibole and serpentine minerals, but instead are loose, flexible and needle-like. These fibres can be found in the mountains, sandstones and cliffs from a variety of nations.
Asbestos can be absorbed into the environment in many ways, such as in airborne particles. It can also leach out into soil or water. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and the anthropogenic (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination of ground and surface water is mostly a result of natural weathering, but it has also been caused by anthropogenic activities like milling and mining, demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated dumping ground in landfills (ATSDR 2001). Airborne asbestos fibres are the main cause of disease among those exposed to asbestos in their work.
Crocidolite
Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can infiltrate the lung, causing serious health problems. These include asbestosis and mesothelioma. Exposure to fibers can occur in a variety of ways including contact with contaminated clothing or building materials. This kind of exposure is particularly dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are softer and less brittle making them more palatable to breathe. They can also be lodged deeper inside lung tissue. It has been linked to a greater number of mesothelioma-related cases than any other form of asbestos.
The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. The most popular asbestos Attorney types are epoxiemite as well as chrysotile which together comprise the majority of commercial asbestos used. The other four asbestos types aren't as common, but may still be present in older structures. They are less dangerous than chrysotile or amosite but can still be a danger when mixed with other minerals, or when mined near other mineral deposits such as vermiculite and talc.
Many studies have discovered an association between exposure to asbestos 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 have reported an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for those who work in mines and chrysotile mills.
The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All asbestos types can cause mesothelioma but the risk is different based on how much exposure, what type of asbestos legal is involved, and how long the exposure lasts. The IARC has recommended that avoid all forms of asbestos should be the highest priority as it is the most secure option for individuals. If you have been exposed to asbestos and suffer from a respiratory disorder or mesothelioma condition, then you should consult your GP or NHS111.
Amphibole
Amphiboles are a grouping of minerals which can form prism-like or needle-like crystals. They are a type of silicate mineral that is composed of double chains of SiO4 molecules. They have a monoclinic system of crystals, but certain crystals have an orthorhombic form. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 Tetrahedrons which are connected in rings of six. Tetrahedrons can be separated by octahedral strips.
Amphiboles are present in both igneous and metamorphic rock. They are usually dark-colored and are hard. Due to their similarity of hardness and colour, they can be difficult for some to distinguish from Pyroxenes. They also share a corresponding cut. However their chemistry permits the use of a variety of compositions. The chemical compositions and crystal structures of the different mineral groups in amphibole could be used to identify them.
Amphibole asbestos consists of chrysotile, and the five types of asbestos: amosite anthophyllite (crocidolite), amosite (actinolite), and amosite. The most widely used asbestos type is chrysotile. Each variety has distinct characteristics. Crocidolite is the most hazardous asbestos type. It contains sharp fibers that can be easily breathed into the lung. Anthophyllite is a brownish to yellowish color and is composed primarily of magnesium and iron. This variety was once used in cement and insulation materials.
Amphiboles are a challenge to analyze due to their complicated chemical structure and the 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 for identifying amphiboles. However, these methods can only provide approximate identifications. For instance, these techniques, cannot distinguish between magnesio hastingsite and magnesio hastingsite. These techniques do not distinguish between ferro-hornblende and.
