The Dangers of Exposure to Asbestos Asbestos was a component in thousands of commercial products prior to when it was banned. According to research, asbestos exposure can cause cancer, as well as other health issues. It is impossible to tell just by looking at a thing if it's made of asbestos. You cannot smell or taste it. Asbestos can only be detected when the materials that contain it are broken, drilled, or chipped. Chrysotile At its peak, chrysotile accounted for 99percent of the asbestos made. It was used in many industries, including construction, insulation, and fireproofing. However, if workers were exposed to this toxic material, they could contract mesothelioma as well as other asbestos related diseases. Fortunately, the use of this harmful mineral has diminished dramatically since mesothelioma awareness began to spread in the 1960's. It is still present in many of the products we use today. Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. Personnel handling chrysotile aren't at risk of being exposed to a high degree of risk based on the current limit of exposure. Lung cancer, lung fibrosis and mesothelioma have all been found to be strongly connected to breathing in airborne respirable fibres. This has been proven to be true for both intensity (dose) and time of exposure. One study that studied the operation of a factory that utilized almost exclusively chrysotile to manufacture friction materials, compared mortality rates in this facility with national mortality rates. The study found that after 40 years of converting low levels of chrysotile there was no significant rise in mortality at this factory. Contrary to other types of asbestos, chrysotile fibers tend to be shorter. They can pass through the lungs and pass into the bloodstream. They are more likely to cause health problems than fibres that are longer. It is extremely difficult for chrysotile fibres be a threat to the air or pose any health risk when mixed with cement. Fibre cement products are extensively utilized in many areas of the world, including schools and hospitals. Research has demonstrated that amphibole asbestos, such as amosite or crocidolite is not as likely than chrysotile to cause disease. Amphibole asbestos types have been the most common cause of mesothelioma as well as other asbestos-related diseases. When cement and chrysotile mix, a durable product is produced that can withstand extreme environmental hazards and weather conditions. It is also simple to clean after use. Asbestos fibers can be easily removed by a professional and then safely eliminated. Amosite Asbestos is a grouping of fibrous silicates that are found in certain types rock formations. It is comprised of six general groups: amphibole, serpentine anthophyllite, tremolite, anthophyllite, crocidolite (IARC, 1973). Asbestos minerals are composed of thin, long fibers that range in length from fine to wide. They can also be curled or straight. They are present in nature in the form of individual fibrils or bundles with splaying edges called fibril matrix. Asbestos can also be found in a powder form (talc), or mixed with other minerals to create talcum powder or vermiculite. These are commonly used as consumer goods, including baby powder, cosmetics and face powder. Asbestos was used extensively in the first two thirds of the 20th century for construction of ships as well as insulation, fireproofing and other construction materials. The majority of occupational exposures were asbestos fibres borne by air, but some workers were exposed to contaminated vermiculite or talc and also to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied by the industry, time frame, and geographic location. Most asbestos-related exposures in the workplace were because of inhalation, but certain workers were exposed through skin contact or through eating contaminated food. Asbestos is found in the natural environment due to natural weathering and degradation of contaminated products, such as ceiling and floor tiles cars, brakes and clutches, and insulation. It is becoming apparent that amphibole fibers that are not commercially available could also be carcinogenic. These are fibres that are not the tightly interwoven fibrils that are found in the amphibole and serpentine minerals, but instead are flexible, loose and needle-like. These fibers can be found in the cliffs and mountains of several countries. Asbestos is absorbed into the environment mostly as airborne particles, but it can also leach into water and soil. This can be triggered by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground water is largely associated with natural weathering, however it has also been triggered by anthropogenic activities like mining and milling, demolition and dispersal of asbestos-containing materials, and the removal of contaminated dumping soil in landfills (ATSDR, 2001). Airborne asbestos fibres are the most significant cause of illness among people exposed to asbestos during their occupation. Crocidolite Inhalation exposure is the most commonly used method of exposure to asbestos fibres. These fibres can enter the lungs and cause serious health problems. Mesothelioma, asbestosis, and other illnesses can be caused by asbestos fibres. Exposure to asbestos fibres can occur in a variety of ways, such as contact with contaminated clothing or materials. This type of exposure is especially dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite is a smaller, more fragile fibers that are easier to inhale and can lodge deeper into lung tissue. It has been linked to a larger number of mesothelioma related cases than any other type of asbestos. The main types are chrysotile as well as amosite. Amosite and chrysotile are two of the most frequently used types of asbestos, and comprise 95% of all asbestos used in commercial construction. The other four types of asbestos haven't been as widely used but they can be present in older buildings. They are less dangerous than amosite and chrysotile, however they can pose a risk when mixed with other asbestos minerals or when mined in close proximity to other naturally occurring mineral deposits, like talc or vermiculite. Several studies have found an connection between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. The evidence is contradictory. Some researchers have cited a 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 working in chrysotile mills and mines. The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All kinds of asbestos can cause mesothelioma or other health issues, but the risks vary according to the amount of exposure that people are exposed to, the type of asbestos used, the duration of their exposure and the way in the way it is inhaled or consumed. IARC has declared that the best option for people is to avoid all types of asbestos. If someone has been exposed to asbestos in the past and are suffering from an illness, such as mesothelioma and other respiratory diseases, they should seek guidance from their doctor or NHS 111. Amphibole Amphiboles comprise a variety of minerals that may form needle-like or prism-like crystals. They are a type of silicate mineral that is composed of double chains of SiO4 molecules. They have a monoclinic arrangement of crystals, but 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. The tetrahedrons can be separated from one another by strips of octahedral sites. Amphiboles are present in metamorphic and igneous rock. They are usually dark-colored and are hard. Due to their similarity in hardness and colour, they can be difficult for some people to distinguish from Pyroxenes. They also share a similar design of cleavage. Their chemistry permits a wide variety of compositions. chico asbestos lawyer in amphibole can be identified by their chemical compositions and crystal structures. Amphibole asbestos consists of chrysotile, and the five types of asbestos amosite anthophyllite (crocidolite), amosite (actinolite), and amosite. The most widely used form of asbestos is chrysotile, each variety has distinct characteristics. The most hazardous type of asbestos, crocidolite, is composed of sharp fibers that are simple to inhale into the lungs. Anthophyllite is yellowish to brown in color and is made up of magnesium and iron. This variety was used to make cement and insulation materials. Amphiboles are a challenge to analyze due to their complicated chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires specialized techniques. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods can only provide approximate identifications. These techniques, for example can't distinguish between magnesio hornblende and hastingsite. In addition, these techniques can not distinguish between ferro-hornblende and pargasite.
