The Dangers of Exposure to Asbestos Before it was banned, asbestos was used in thousands commercial products. Research suggests that exposure to asbestos can cause cancer and other health problems. It is not possible to tell by simply looking at something whether it is made up of asbestos. It is also impossible to 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 made up for 99% of the asbestos made. It was utilized in a variety of industries including construction insulation, fireproofing and insulation. If workers were exposed to the toxic material, they may develop mesothelioma, as well as other asbestos-related diseases. Since the 1960s, when mesothelioma was first becoming a major concern, the use of asbestos has declined significantly. However, trace amounts remain in the products we use in the present. Chrysotile can be used in a safe manner when a thorough safety and handling plan is put into place. Chrysotile handling workers aren't exposed to a significant amount of risk at current limit of exposure. Lung cancer, lung fibrosis and mesothelioma have been strongly connected to breathing in airborne respirable fibres. This has been proven to be true for both intensity (dose) and the duration of exposure. One study that examined the operation of a factory that utilized almost exclusively chrysotile to manufacture friction materials compared mortality rates at this factory with national mortality rates. The study revealed that after 40 years of processing at low levels of chrysotile, there was no significant rise in mortality rates in this factory. phoenix asbestos attorneys are usually 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 with longer lengths. It is extremely difficult for chrysotile fibres be in the air or pose a health risk when mixed with cement. Fibre cement products are widely used in a variety of locations around the world including hospitals and schools. Research has proven that chrysotile is less prone to cause disease than amphibole asbestos like crocidolite and amosite. Amphibole asbestos forms have been the primary cause of mesothelioma and other asbestos-related diseases. When cement and chrysotile are mixed with cement, a tough and flexible material is created that is able to withstand extreme weather conditions and environmental hazards. It is also easy to clean up after use. Asbestos fibres are easily removed by a professional and disposed of. Amosite Asbestos is one of the groups of fibrous silicates that are found in various types of rock formations. It consists of six general groups: serpentine, amphibole, tremolite, anthophyllite and crocidolite (IARC, 1973). Asbestos minerals are made up of long, thin fibers that range in length from fine to wide. They can also be curled or straight. They can be found in nature in bundles, or as individual fibrils. Asbestos can also be found in a powder form (talc), or mixed with other minerals to make vermiculite or talcum powder. These are commonly used as consumer goods, including baby powder, cosmetics and face powder. Asbestos was used extensively in the early two-thirds of the 20th century to construct shipbuilding as well as insulation, fireproofing and other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, however some workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied from industry to industry, era to and geographic location. Most asbestos exposures at work were caused by inhalation, however some workers were also exposed by skin contact or by eating food contaminated with asbestos. Asbestos is only found in the air due to natural weathering and degrading of contaminated materials, such as ceiling and floor tiles cars, brakes and clutches, and insulation. It is becoming clear that non-commercial amphibole fibers can also be carcinogenic. These are the fibres that don't form the tightly weaved fibrils of amphibole and serpentine minerals but instead are loose, flexible and needle-like. These fibers can be found in the mountains, sandstones and cliffs of a variety of countries. Asbestos gets into the environment primarily as airborne particles, but it can also be absorbed into soil and water. This can be due to both natural (weathering of asbestos-bearing rocks) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of ground and surface water is mostly due to natural weathering, however it has also been caused by anthropogenic activities like milling and mining demolition and dispersal asbestos-containing materials as well as the disposal of contaminated dumping soil in landfills (ATSDR, 2001). Airborne asbestos fibres are the most significant reason for illness among those exposed to asbestos in their occupation. Crocidolite Inhalation exposure is the most frequent method of exposure to asbestos fibres. These fibres can enter the lungs which can cause serious health issues. These include mesothelioma and asbestosis. Exposure to the fibres can also take place in other ways, such as contact with contaminated clothing or building materials. The dangers of this kind of exposure are greater when crocidolite, a asbestos in the blue form, is involved. Crocidolite fibers are thinner and more fragile and therefore easier to inhale. They can also get deeper within lung tissues. It has been linked to more mesothelioma cases than other types of asbestos. The six major types of asbestos are chrysotile amosite, epoxiemite, tremolite, anthophyllite, and actinolite. The most commonly used asbestos types are epoxiemite and chrysotile which together comprise the majority of commercial asbestos used. The other four have not been as widely used however, they could be present in older buildings. They are less hazardous than amosite and chrysotile. However, they can pose a risk when mixed with other asbestos minerals or when mined close to other mineral deposits, such as vermiculite or talc. A number of studies have demonstrated an connection between exposure to asbestos and stomach cancer. Several studies have found a link between asbestos exposure and stomach. However the evidence isn't conclusive. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers, and others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for workers in chrysotile mines and mills. The International Agency for Research on Cancer (IARC) has classed all asbestos types as carcinogenic. All asbestos types can cause mesothelioma however the risks differ based on how much exposure, the type of asbestos is involved, and the length of time that exposure lasts. The IARC has recommended that the prevention of all asbestos types is the most important thing to do because this is the safest option for those who are exposed. If you've been exposed in the past to asbestos and suffer from a respiratory illness or mesothelioma, then you should see your physician or NHS111. Amphibole Amphiboles are groups of minerals that form prism-like and needle-like crystals. They are a type of silicate mineral that is composed of double chains of molecules of SiO4. They typically 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 series of six tetrahedrons. The tetrahedrons can be separated by octahedral strips. Amphiboles occur in both igneous and metamorphic rock. They are usually dark and hard. They can be difficult to differentiate from pyroxenes due to their similar hardness and colors. They also share a similar cut. However their chemistry allows many different compositions. The chemical compositions and crystal structure of the different mineral groups in amphibole can be used to determine their composition. Amphibole asbestos is comprised of chrysotile as well as the five asbestos types amosite, anthophyllite (crocidolite) amosite (actinolite), and amosite. While the most commonly used form of asbestos is chrysotile. Each variety is unique in its own way. Crocidolite is considered to be the most hazardous asbestos kind. It has sharp fibers that can be easily breathed into the lung. Anthophyllite ranges from brown to yellowish in color and is made up of magnesium and iron. This kind of material was used to create cement and insulation materials. Amphiboles are a challenge to analyze due to their complicated chemical structure and numerous substitutions. A detailed analysis of the composition of amphibole mineral requires specialized techniques. The most commonly used methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods can only give approximate identifications. For instance, these techniques, cannot distinguish between magnesio hastingsite and magnesio hastingsite. These techniques do not distinguish between ferro-hornblende and pargasite.
