The Dangers of Exposure to Asbestos Before it was banned, asbestos was used in a myriad of commercial products. Research has shown that exposure to asbestos can cause cancer as well as other health issues. It is impossible to determine if a product is asbestos-containing by looking at it, and you are unable to taste or smell it. Asbestos can only be detected when the substances that contain it are broken or drilled. Chrysotile At its peak, chrysotile made the majority of asbestos production. It was widely used in industries, including construction insulation, fireproofing, and insulation. If workers were exposed to this toxic substance, they could develop mesothelioma or other asbestos related diseases. Thankfully, the use this toxic mineral has decreased drastically since mesothelioma awareness started to spread in the 1960's. It is still present in a variety of products we use today. Chrysotile can be used in a safe manner with a well-thought-out safety and handling plan is put in place. Personnel handling chrysotile aren't at risk of being exposed to a high degree of risk based on the current safe exposure levels. Lung fibrosis, lung cancer and mesothelioma are all linked to breathing airborne respirable fibres. This has been confirmed for both the intensity (dose) and duration of exposure. In one study, mortality rates were compared between a factory which used almost exclusively chlorosotile to make friction materials and national death rates. It was concluded that for 40 years of preparing asbestos chrysotile at a low level of exposure there was no significant extra mortality in the factory. In contrast to other forms of asbestos, chrysotile fibres tend to be smaller. They are able to enter the lungs and then enter the bloodstream. They are therefore more likely to cause health issues than longer fibres. When chrysotile is mixed into cement, it's very difficult for the fibres to air-borne and pose any health risks. Fibre cement products are extensively used throughout the world, especially in buildings such as schools and hospitals. Studies have shown that chrysotile has a lower chance to cause disease than amphibole asbestos, such as crocidolite and amosite. Amphibole asbestos kinds have been the main cause of mesothelioma as well as other asbestos-related illnesses. When chrysotile gets mixed with cement, it creates a tough, flexible building product that can withstand the most extreme weather conditions and other environmental hazards. It is also simple to clean after use. Asbestos fibres are easily removed by a professional and then safely removed. Amosite Asbestos refers to a group of silicate fibrous minerals that are found naturally in specific kinds of rock formations. It is comprised of six general groups: amphibole, serpentine, tremolite, anthophyllite and crocidolite (IARC 1973). Asbestos minerals are made up of thin, long fibers that range in length from fine to wide. They can also be straight or curled. These fibres can be found in nature in bundles or individual fibrils. Asbestos is also found in a powder form (talc) or mixed with other minerals in order to create vermiculite or talcum powder. These are widely used in consumer products like baby powder, cosmetics and facial powder. The most extensive asbestos use was during the first two-thirds period of the 20th century in the period when it was employed in insulation, shipbuilding, fireproofing, and other construction materials. Most occupational exposures were asbestos fibres in the air, however certain workers were exposed to vermiculite or talc that was contaminated and also to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied according to the type of industry, the time period and geographical location. Asbestos exposure in the workplace is mainly because of inhalation. However there have been instances of workers being exposed by contact with their skin or eating contaminated foods. Asbestos is found in the environment due to natural weathering and degrading of contaminated materials like ceiling and floor tiles cars, brakes and clutches, and insulation. It is becoming increasingly apparent that non-commercial amphibole fibers can also be carcinogenic. san francisco asbestos lawyer are not tightly woven like the fibrils found in serpentine and amphibole, they are loose as well as flexible and needle-like. These fibers are found in the mountains and cliffs of several countries. Asbestos can be found in the environment as airborne particles, but it can also leach into soil and water. This can be triggered by both natural (weathering of asbestos-bearing rocks) and anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground water is mostly a result of natural weathering, however it has also been caused by anthropogenic activities such as mining and milling demolition and dispersal of asbestos-containing material and the disposal of contaminated dumping soil in landfills (ATSDR, 2001). Airborne asbestos fibres are the primary cause of illness among people exposed to asbestos during their job. Crocidolite Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can enter the lungs and cause serious health issues. Mesothelioma and asbestosis as well as other diseases are all caused by asbestos fibres. Exposure to asbestos fibers can be experienced in other ways, such as contact with contaminated clothes or building materials. This kind of exposure is particularly dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are thinner and more fragile, making them easier to breathe in. They can also get deeper within lung tissue. It has been linked to a higher number of mesothelioma related cases than any other form of asbestos. The six major types are chrysotile, amosite and chrysotile. The most well-known forms of asbestos are chrysotile and epoxiemite, which together make up the majority of commercial asbestos employed. The other four asbestos types aren't as prevalent, but could still be found in older structures. They are not as hazardous as amosite and chrysotile, however they may pose a danger when mixed with other asbestos minerals, or when mined in close proximity to other mineral deposits, like talc or vermiculite. Several studies have found an connection between exposure to asbestos and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. However there is no conclusive evidence. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% of the time CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95% 95% CI: 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 types of asbestos carcinogenic. All types of asbestos can cause mesothelioma or other health issues, but the risks vary according to the amount of exposure people are exposed to, the kind of asbestos involved as well as the length of their exposure and the manner in the way that it is breathed in or ingested. The IARC has advised that avoid all forms of asbestos should be the top priority since this is the most safe option for individuals. However, if someone has been exposed to asbestos in the past and are suffering from a condition such as mesothelioma and other respiratory ailments and require advice, they should seek out guidance from their physician or NHS 111. Amphibole Amphiboles are groups of minerals which can form needle-like or prism-like crystals. They are an inosilicate minerals made of double chains of SiO4 molecules. They are a monoclinic system of crystals, however 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. Tetrahedrons may be separated by strips of octahedral site. Amphibole minerals can be found in igneous and metamorphic rocks. They are usually dark-colored and tough. They can be difficult to differentiate from pyroxenes because they have similar hardness and color. They also share a similar design of cleavage. However their chemistry allows a wide range of compositions. The chemical compositions and crystal structure of the various minerals in amphibole can be used to determine their composition. Amphibole asbestos consists of chrysotile, and the five asbestos types amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. While the most popular form of asbestos is chrysotile; each has its own distinct characteristics. The most dangerous form of asbestos, crocidolite is made up of sharp fibers that are simple to inhale into the lung. Anthophyllite ranges from brown to yellowish in color and is composed of iron and magnesium. This kind of stone was used to create cement and insulation materials. Amphibole minerals are difficult to analyze because they have a a complicated chemical structure and a variety of substitutions. An in-depth analysis of the composition of amphibole mineral requires specialized techniques. The most widely used methods of identifying amphiboles include EDS, WDS, and XRD. However, these methods can only give approximate identifications. These methods, for instance cannot differentiate between magnesio hornblende and magnesio hastingsite. These techniques also do not differentiate between ferro-hornblende or pargasite.
