The Dangers of Exposure to Asbestos
Asbestos was a component in thousands of commercial products before it was banned. According research, exposure to asbestos can cause cancer and many other health problems.
It is difficult to tell by taking a look at something if it contains asbestos. You cannot taste or smell it. Asbestos can only be identified when the materials that contain it are broken or drilled.
Chrysotile
At its peak, chrysotile made up for 95% of the asbestos produced. It was widely used in industries, including construction insulation, fireproofing, as well as insulation. If workers are exposed to asbestos, they could develop mesothelioma along with other asbestos-related diseases. Since the 1960s, when mesothelioma first became a major concern asbestos use has been reduced significantly. However, trace amounts of it are still present in many of the products we use in the present.
Chrysotile is safe to use in the event that a thorough safety and handling plan is put in place. People who handle chrysotile do not exposed to an undue amount of risk at the present safe exposure levels. Inhaling airborne fibres is strongly linked to lung fibrosis and lung cancer. This has been confirmed for both the intensity (dose) and time of exposure.
In one study mortality rates were compared between a manufacturing facility that used a large proportion of chrysotile in the manufacture of friction materials and national death rates. The study found that, after 40 years of processing low levels of chrysotile, there was no significant increase in mortality rates in this factory.
Chrysotile fibres tend to be shorter than other types of asbestos. They can pass through the lungs and enter the bloodstream. They are therefore more likely to cause health problems than fibres that are longer.
It is extremely difficult for chrysotile fibers to be a threat to the air or pose any health risk when mixed with cement. Fibre cement products have been extensively used across the globe particularly in buildings such as schools and hospitals.
Research has demonstrated that amphibole asbestos like crocidolite or asbestos amosite is less likely than chrysotile to cause diseases. These amphibole types have been the most common cause of mesothelioma and various asbestos-related illnesses. When cement and chrysotile mix together, a strong product is produced that is able to stand up to extreme weather conditions and environmental hazards. It is also easy to clean after use. Professionals can safely dispose of asbestos fibres after they have been removed.
Amosite
Asbestos is a category of silicate minerals with fibrous structure that occur naturally in certain types of rock formations. It is classified into six groups: amphibole (serpentine), the tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.
Asbestos minerals are composed of long, thin fibers that vary in length from fine to broad. They can also be straight or curled. They can be found in nature in bundles or individual fibrils. Asbestos is also found in powder form (talc) or combined with other minerals in order to create talcum powder or vermiculite. They are used extensively as consumer goods, like baby powder, cosmetics and facial powder.
The most extensive use of asbestos occurred in the first two-thirds of the 20th century when it was utilized in insulation, shipbuilding, fireproofing and other construction materials. The majority of occupational exposures to asbestos fibres were in the air, but some workers were also exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied according to industry, time and geographic location.
Asbestos exposure in the workplace is mostly because of inhalation. However there have been instances of workers being exposed through skin contact or eating contaminated foods. Asbestos can only be found in the environment due to natural weathering and degrading of contaminated materials, such as ceiling and floor tiles cars, brakes and clutches, and insulation.
There is evidence to suggest that amphibole fibres from non-commercial sources could also be carcinogenic. These are fibers that do not have the tight woven fibrils of the amphibole or serpentine minerals but instead are loose, flexible and needle-like. These fibers can be found in the mountains and cliffs in a variety of countries.
Asbestos is able to enter the environment in many ways, including as airborne particles. It is also able to leach into soil or water. This can be triggered by both natural (weathering of asbestos-bearing rock) and anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is mostly a result of natural weathering, but has also been caused by anthropogenic activities such as milling and mining demolition and dispersal asbestos-containing materials, and the removal of contaminated dumping soils in landfills (ATSDR, 2001). Airborne asbestos fibres are the most significant cause of illness among people exposed to it in their work.
Crocidolite
Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can infiltrate the lungs and cause serious health problems. Mesothelioma and asbestosis as well as other illnesses are caused by asbestos fibres. Exposure to fibers can occur in a variety of ways, such as contact with contaminated clothing or building materials. This type of exposure is more dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are less dense and more fragile making them more palatable to inhale. They can also get deeper inside lung tissues. It has been linked to more mesothelioma cases than other asbestos types.
The six main types of asbestos [go!!] are chrysotile amosite and tremolite. They are epoxiemite, tremol anthophyllite, and actinolite. Chrysotile and amosite are the most commonly used types of asbestos and account for 95% of the commercial asbestos currently used. The other four asbestos types are not as common, but may still be found in older structures. They are less hazardous than amosite or chrysotile however they could still pose a threat when combined with other minerals or when mined near other mineral deposits, such as vermiculite and talc.
Numerous studies have demonstrated an association between stomach cancer and asbestos exposure. The evidence is contradictory. Some researchers have reported an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers. However, others report an SMR of 1,24 (95% confidence interval: 0.76-2.5), for those who work in chrysotile mills and mines.
The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All kinds of asbestos may cause mesothelioma as well as other health problems, but the risks vary according to the amount of exposure people are exposed to, the type of asbestos compensation used as well as the duration of exposure and the manner in which it is breathed in or ingested. IARC has declared that the best choice for people is to avoid all types of asbestos. If you've been exposed to asbestos and suffer from a respiratory condition or mesothelioma, then you should seek advice from your physician or NHS111.
Amphibole
Amphiboles are a grouping of minerals which can create prism-like or needle-like crystals. They are a type inosilicate mineral made up of two chains of SiO4 molecules. They usually have a monoclinic structure in their crystals however some may have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are composed of (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. Tetrahedrons may be separated by octahedral strips.
Amphibole minerals can be found in metamorphic and igneous rocks. They are usually dark and hard. Because of their similar hardness and color, they can be difficult for some to differentiate from the pyroxenes. They also share a similar pattern of cleavage. Their chemistry allows for a range of compositions. The various mineral groups within amphibole are identified by their chemical compositions and crystal structures.
The five types of asbestos in the amphibole family include amosite, anthophyllite as well as crocidolite and actinolite. Each type of asbestos has distinct characteristics. The most harmful type of asbestos, crocidolite is made up of sharp fibers that are simple to inhale into the lungs. Anthophyllite can be found in a brownish or yellowish hue and is comprised mostly of iron and magnesium. This variety was once used in cement and insulation materials.
Amphiboles are difficult to analyse due to their complicated chemical structure and numerous substitutions. A thorough analysis of the composition of amphibole minerals requires specialized methods. EDS, WDS and XRD are the most popular methods for identifying amphiboles. These methods can only provide approximate identifications. For instance, these methods are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. These techniques also don't distinguish between ferro-hornblende as well as pargasite.
