The Dangers of Exposure to Asbestos
Asbestos was used in thousands of commercial products before it was banned. Research shows that exposure to asbestos can cause cancer and other health problems.
It is impossible to determine if a product has asbestos just by looking at it, and you cannot taste or smell it. It is only discovered when asbestos-containing materials are drilled, chipped or broken.
Chrysotile
At its peak, chrysotile made up for 99% of the asbestos made. It was utilized in a variety of industries like construction insulation, fireproofing, and insulation. If workers are exposed to asbestos, they could develop mesothelioma and other asbestos-related diseases. Since the 1960s, when mesothelioma began to become an issue, the use of asbestos has declined significantly. However, traces of it can still be found in products that we use today.
Chrysotile is safe to use when you have a thorough safety and handling program in place. It has been proven that at the current controlled exposure levels, there is no danger to the people who handle the substance. Lung fibrosis, lung cancer and mesothelioma have been strongly linked to breathing airborne respirable fibres. This has been confirmed both in terms of intensity (dose) as well as duration of exposure.
In one study, mortality rates were compared between a factory that used a large proportion of chlorosotile to make friction materials and national death rates. The study concluded that, after 40 years of processing at low levels of chrysotile there was no significant rise in mortality rates in this factory.
Contrary to other types of asbestos, chrysotile fibres tend to be smaller. They can enter the lungs, and even enter the bloodstream. This makes them more likely to cause ill-health effects than fibres with longer lengths.
When chrysotile is mixed into cement, it is extremely difficult for the fibres to air-borne and pose health risks. Fibre cement products are widely used in many parts of the world, including schools and hospitals.
Research has revealed that amphibole asbestos, like amosite or crocidolite is not as likely than chrysotile in causing diseases. Amphibole types like these are the main cause of mesothelioma, and other asbestos lawyer-related diseases. When chrysotile is mixed in with cement, it creates a tough, flexible building product that can withstand extreme conditions in the weather and other environmental dangers. It is also simple to clean after use. Professionals can safely dispose of asbestos fibres after they have been removed.
Amosite
Asbestos is a class of fibrous silicates that are found in certain types of rock formations. It consists of six general groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC 1973).
Asbestos minerals are made up of long, thin fibres that range in length from extremely fine to broad and straight to curled. They are found in nature as individual fibrils or bundles with splaying ends referred to as a fibril matrix. Asbestos minerals are also found in the form of 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, face powder and cosmetics.
asbestos Case - Http://62.99.192.212/ - was widely used during the first two thirds of the 20th century to construct shipbuilding, insulation, fireproofing, and Asbestos case other construction materials. The majority of asbestos-related exposures in the workplace were in the air, but certain workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied according to the type of industry, the time period and geographical location.
Most of the occupational exposures to asbestos were due to inhalation, but some workers were also exposed through contact with skin or by eating food contaminated with asbestos. Asbestos is currently only found in the environment due to the natural weathering of mined ore and deterioration of contaminated products such as insulation, car brakes, clutches, and floor and ceiling tiles.
There is emerging evidence that non-commercial amphibole fibres may also be carcinogenic. They are not tightly knit like the fibrils found in serpentine and amphibole, but are instead loose as well as flexible and needle-like. These fibers can be found in the cliffs and mountains of several countries.
Asbestos can be found in the environment in the form of airborne particles, however it also leaches into water and soil. This is a result of both natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination of ground and Asbestos Case surface water is mostly due to natural weathering, however it has also been caused by human activities like milling and mining, demolition and dispersal of asbestos-containing material and the disposal of contaminated dumping soils in landfills (ATSDR 2001). Airborne asbestos legal fibres are the primary cause of disease among those exposed to asbestos during their occupation.
Crocidolite
Inhalation exposure is the most commonly used method of exposure to asbestos fibres. The fibres can penetrate the lungs which can cause serious health issues. These include asbestosis and mesothelioma. Exposure to fibres can occur in other ways as well including contact with contaminated clothing or materials. The dangers of this kind of exposure are more pronounced when crocidolite which is the asbestos' blue form is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe in and can get deeper into lung tissue. It has been linked to a greater number of mesothelioma cases than any other type of asbestos.
The six main types of asbestos are chrysotile, amosite as well as epoxiemite. Tremolite is anthophyllite, and actinolite. Chrysotile and amosite are among the most commonly used types of asbestos, and comprise 95% of the commercial asbestos that is used. The other four have not been as widely utilized however they can be present in older buildings. They are not as dangerous as amosite or chrysotile but still be a danger when combined with other minerals or when mined near other mineral deposits like talc and vermiculite.
Numerous studies have proven an association between stomach cancer and asbestos exposure. The evidence isn't conclusive. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95 percent 95% confidence interval: 0.7-3.6) for all asbestos-related workers 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.
IARC The IARC, also known as the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All forms of asbestos could cause mesothelioma or other health issues, but the risk is dependent on the amount of exposure individuals are exposed to, the type of asbestos used, the duration of their exposure, and the manner in which it is inhaled or ingested. The IARC has recommended that abstaining from all asbestos forms is the most important thing to do as it is the most secure option for people. If you've been exposed in the past to asbestos claim and suffer from a respiratory condition or mesothelioma, you should see your physician or NHS111.
Amphibole
Amphiboles are a grouping of minerals that can create prism-like or needle-like crystals. They are a type of inosilicate mineral made up 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 comprise (Si, Al)O4 tetrahedrons linked together by tetrahedron rings made of six. The tetrahedrons can be separated from each other by strips of octahedral sites.
Amphiboles are present in both igneous and metamorphic rock. They are usually dark and hard. They are sometimes difficult to distinguish from pyroxenes due to their similar hardness and color. They also share a corresponding cleavage. Their chemistry permits a wide range of compositions. The chemical compositions and crystal structure of the various mineral groups found in amphibole may be used to determine their composition.
The five asbestos types in the amphibole class include chrysotile, anthophyllite, amosite and crocidolite. They also include actinolite. Each variety of asbestos has its own unique properties. Crocidolite is considered to be the most hazardous asbestos type. It is made up of sharp fibers that can be easily inhaled into the lungs. Anthophyllite is a brownish to yellowish color and is composed mostly of iron and magnesium. This type of stone was once used in products such as cement and insulation materials.
Amphibole minerals are difficult to analyze because they have a an intricate chemical structure and many substitutions. A thorough analysis of the composition of amphibole minerals is a complex process that requires specialized techniques. The most common methods of identifying amphiboles include EDS, WDS, and XRD. These methods are only able to provide approximate identifications. For instance, these techniques can't distinguish between magnesio-hornblende and hastingsite. Furthermore, these techniques do not distinguish between ferro-hornblende and pargasite.
