The Dangers of Exposure to Asbestos Asbestos was a component in thousands of commercial products prior to when it was banned. According to research, exposure to asbestos can cause cancer as well as other health issues. It is difficult to tell if something includes asbestos simply by looking at it and you cannot taste or smell it. Asbestos can only be detected when the materials that contain it are broken, drilled, or chipped. Chrysotile At its height, chrysotile was responsible for 99% of the asbestos created. It was employed in a variety of industries, including construction, insulation, and fireproofing. If workers are exposed to asbestos, they could develop mesothelioma or other asbestos-related illnesses. Since the 1960s, when mesothelioma began to become a major concern asbestos use has been drastically reduced. However, traces of it are still present in common products that we use today. Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. It has been found that, at today's controlled exposure levels, there isn't an undue risk to the workers working with the substance. 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 the duration of exposure. One study that looked into the operation of a factory that utilized almost all chrysotile as its friction materials, compared mortality rates in this facility with national death rates. The study concluded that, after 40 years of converting low levels of chrysotile there was no significant increase in mortality in this factory. Chrysotile fibres are usually shorter than other types of asbestos. They can pass through the lungs and pass into the bloodstream. This makes them much more likely to cause ill-health consequences than longer fibres. When chrysotile is mixed into cement, it is extremely difficult for the fibres to breathe and cause health hazards. Fibre cement products are extensively used in various parts of the world, including schools and hospitals. Studies have shown that chrysotile has a lower chance to cause disease than amphibole asbestos such as crocidolite and amosite. Amphibole types like these are the primary cause of mesothelioma, and other asbestos-related diseases. When the cement and chrysotile are combined together, a strong and flexible material is created that is able to stand up to extreme weather conditions and environmental hazards. It is also easy to clean after use. Asbestos fibres can be easily removed by a professional, and then removed. Amosite Asbestos is a term used to describe a class of silicate minerals with fibrous structure which are found naturally in a variety of kinds of rock formations. It is divided into six groups: amphibole (serpentine) and tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are made up of long, thin fibers that vary in length from fine to broad. They can be curled or straight. They are found in nature in the form of individual fibrils or bundles that have splaying ends, referred to as a fibril matrix. Asbestos can also be found in powder form (talc), or mixed with other minerals in order to create vermiculite or talcum powder. They are extensively used in consumer products like baby powder, cosmetics and facial powder. Asbestos was heavily used in the early two-thirds of the 20th century to construct construction of ships, insulation, fireproofing, and other construction materials. The majority of asbestos exposures for work 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 geographic location. The exposure to asbestos at work is mostly caused by inhalation. However there have been instances of workers being exposed through contact with skin or eating food that is contaminated. Asbestos is currently only found in the air due to the natural weathering of mined minerals and the degrading of contaminated materials like insulation, car brakes, clutches and ceiling and floor tiles. It is becoming clear that non-commercial amphibole fibers could also be carcinogenic. These fibers aren't tightly knit like the fibrils found in amphibole or serpentine, but are instead loose, flexible, and needle-like. These fibers are found in the mountains and cliffs in a variety of countries. Asbestos is able to enter the environment in a variety ways, including through airborne particles. It can also be released into water or soil. This occurs both from 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 surface water is mostly due to natural weathering, but has also been caused by anthropogenic activities such as milling and mining demolition and dispersal asbestos-containing material and the disposal of contaminated dumping ground in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the main reason for illness among those who are exposed to it during their occupation. Crocidolite Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can get into the lungs, causing serious health problems. These include mesothelioma and asbestosis. hawthorne asbestos lawyer to fibers can occur in other ways, too like contact with contaminated clothing or materials. This kind 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 can get deeper into lung tissue. It has been linked to more mesothelioma-related cases than other asbestos types. The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite anthophyllite and actinolite. Chrysotile and amosite are among the most commonly used forms of asbestos. They comprise 95 percent of all commercial asbestos currently used. The other four asbestos types aren't as common, but may still be found in older structures. They are less dangerous than amosite or chrysotile however they could still be dangerous when combined with other minerals or when mined near other mineral deposits, such as talc and vermiculite. Numerous studies have shown the connection between stomach cancer and asbestos exposure. The evidence is contradictory. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, while others report an SMR of 1,24 (95% confidence interval: 0.76-2.5), for those working in chrysotile mines and mills. IARC The IARC, which is the International Agency for Research on Cancer, has classified all kinds of asbestos as carcinogenic. All types of asbestos can cause mesothelioma and other health issues, although the risks are different based on the amount of exposure people are exposed to, the kind of asbestos involved as well as the duration of exposure and the manner in which it is inhaled or ingested. The IARC has advised that the prevention of all asbestos types should be the highest priority, as this is the most secure option for those who are exposed. If you've been exposed in the past to asbestos and suffer from a respiratory disorder or mesothelioma, then you should consult your GP or NHS111. Amphibole Amphiboles are a grouping of minerals that create prism-like or needle-like crystals. They are an inosilicate mineral composed of double chains of SiO4 molecules. They usually possess a monoclinic crystal system, although some have an orthorhombic structure. 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 strips of octahedral sites. Amphiboles are present in both igneous and metamorphic rock. They are usually dark-colored and tough. They can be difficult to distinguish from pyroxenes since they share similar hardness and colors. They also have a similar Cleavage. However their chemistry permits a wide range of compositions. The chemical compositions and crystal structures of the different mineral groups found in amphibole may be used to determine their composition. Amphibole asbestos is comprised of chrysotile as well as the five types of asbestos amosite, anthophyllite (crocidolite) amosite (actinolite), and amosite. While the most commonly used asbestos type is chrysotile; each has its own unique characteristics. Crocidolite is among the most dangerous asbestos type. It is made up of sharp fibers that are easily breathed into the lung. Anthophyllite ranges from brown to yellowish in color and is composed of magnesium and iron. This kind of stone was used to create cement and insulation materials. Amphibole minerals are challenging to analyze due to their complex chemical structures and a variety of substitutions. Therefore, a detailed analysis of their composition requires special methods. The most commonly used methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods can only give approximate identifications. These techniques, for instance, cannot distinguish between magnesio hornblende and hastingsite. These techniques also cannot distinguish between ferro-hornblende and pargasite.
