The Dangers of Exposure to Asbestos Before it was banned, asbestos was widely used in commercial products. According to studies, exposure to asbestos can cause cancer and a host of other health problems. It is difficult to tell by looking at something whether it is made up of asbestos. Also, you cannot smell or taste it. Asbestos can only be identified when the material containing it is broken or drilled. Chrysotile At its height, chrysotile comprised up 99% of the asbestos produced. It was employed in many industries, including construction insulation, fireproofing and insulation. In the event that workers were exposed for long periods to this toxic material, they could contract mesothelioma and other asbestos-related diseases. Thankfully, the use of this dangerous mineral has decreased significantly since awareness of mesothelioma began to increase in the 1960's. However, trace amounts of it are still present in many of the products we use in the present. Chrysotile is safe to use when you have a thorough safety and handling plan in place. Chrysotile handling workers aren't exposed to an undue amount of risk at the current limit of exposure. Lung cancer, lung fibrosis and mesothelioma were all linked to breathing airborne respirable fibres. This has been confirmed in terms of intensity (dose) as and the duration of exposure. One study that looked into an industrial facility that used almost exclusively chrysotile for manufacturing friction materials compared mortality rates at this factory with national death rates. The study revealed that after 40 years of processing low levels of chrysotile, there was no significant increase in mortality at this factory. Chrysotile fibers are generally shorter than other types of asbestos. They are able to enter the lungs and then enter the bloodstream. They are more likely to cause health issues than fibres that are longer. When chrysotile is mixed into cement, it's extremely difficult for the fibres to be airborne and pose health risks. Fibre cement products are used extensively throughout the world particularly in structures like hospitals and schools. Research has demonstrated that amphibole asbestos, like amosite, crocidolite, or crocidolite, is less likely than chrysotile in causing diseases. Amphibole types like these are the main cause of mesothelioma, and other asbestos-related diseases. When chrysotile is mixed in with cement, it forms a tough, flexible building product that is able to withstand severe conditions in the weather and other environmental hazards. It is also easy to clean up after use. Professionals can safely get rid of asbestos fibres after they have been removed. Amosite Asbestos is a category of fibrous silicates found in various types of rock formations. It is classified into six groups including amphibole (serpentine) and Tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are made up of thin, long fibres that vary in length, ranging from very fine to broad and straight to curled. They are found in nature as individual fibrils or bundles with splaying ends referred to as a fibril matrix. Asbestos can also be found in a powder form (talc) or combined with other minerals to create vermiculite or talcum powder. They are extensively used in consumer products such as baby powder cosmetics and facial powder. The most extensive use of asbestos was in the first two-thirds of 20th century where it was used in shipbuilding, insulation, fireproofing, and other construction materials. The majority of occupational exposures were airborne asbestos fibres, but some workers were exposed contaminated vermiculite or talc and to pieces of asbestos-bearing rock (ATSDR 2001). Exposures varied according to industry, time period and geographical location. The majority of asbestos exposures that workers were exposed to was because of inhalation, but certain workers were exposed via skin contact or through eating contaminated food. Asbestos can be found in the environment from natural weathering of mined ores and deterioration of contaminated products such as insulation, car brakes, clutches, and floor and ceiling tiles. It is becoming increasingly apparent that non-commercial amphibole fibres may also be carcinogenic. These are fibres that do not form the tightly weaved fibrils of amphibole and serpentine minerals, but instead are loose, flexible and needle-like. These fibers are found in mountain sandstones, cliffs and sandstones of many countries. Asbestos gets into the environment primarily as airborne particles, but it also leaches into water and soil. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing wastes in landfill sites) sources. Asbestos contamination of surface and ground water is mostly a result of natural weathering, but it has also been caused by human activities like mining and milling demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated dumping soils in landfills (ATSDR, 2001). Airborne asbestos fibres are the primary cause of illness in people exposed to asbestos in their work. Crocidolite Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can infiltrate the lung, causing serious health problems. This includes asbestosis and mesothelioma. The exposure to asbestos can happen in other ways, too including contact with contaminated clothing, or building materials. The risks of exposure are more pronounced when crocidolite, the blue form of asbestos, is involved. Crocidolite fibers are smaller and more fragile, making them easier to breathe. They can also be lodged deeper within lung tissue. It has been associated with more mesothelioma cases than other types of asbestos. The six major types are chrysotile and amosite. The most well-known asbestos types are epoxiemite and chrysotile, which together comprise 95% all commercial asbestos used. The other four asbestos types are not as well-known, but can still be present in older structures. They are less harmful than amosite and chrysotile. However, they could be a risk when mixed with other asbestos minerals or mined in close proximity to other naturally occurring 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 the evidence is not conclusive. 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 have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for those working in chrysotile mines or chrysotile mills. The International Agency for Research on Cancer (IARC) has classified all asbestos types as carcinogenic. All kinds of asbestos may cause mesothelioma and other health issues, although the risks differ based on the amount of exposure people are exposed to, the type of asbestos used, the duration of their exposure and the manner in the way that it is breathed in or consumed. IARC has declared that the best option for people is to stay clear of all forms of asbestos. However, if people have been exposed to asbestos in the past and suffer from a condition such as mesothelioma, or other respiratory conditions, they should seek guidance from their physician or NHS 111. Amphibole Amphibole belongs to a group of minerals that form long prisms or needle-like crystals. They are an inosilicate mineral made up of double chains of SiO4 molecules. They have a monoclinic arrangement of crystals, but certain crystals have an orthorhombic form. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are made up of (Si,Al)O4 Tetrahedrons that are joined in rings of six. lorain asbestos lawsuit can be separated from one another by strips of octahedral sites. Amphibole minerals are common in metamorphic and igneous rocks. They are typically dark-colored and hard. They are sometimes difficult to differentiate from pyroxenes due to their similar hardness and colors. They also share a corresponding design of cleavage. Their chemistry allows for a variety of compositions. The chemical compositions and crystal structures of the various mineral groups in amphibole could be used to identify them. Amphibole asbestos comprises chrysotile and the five types of asbestos amosite, anthophyllite (crocidolite), amosite (actinolite), and amosite. Each type of asbestos has its own distinctive properties. Crocidolite is among the most dangerous asbestos type. It has sharp fibers that can easily be inhaled into the lung. Anthophyllite is brown to yellowish in color and is composed of iron and magnesium. This type of stone was once used in products like cement and insulation materials. Amphibole minerals are hard to analyze due to their complex chemical structures and many substitutions. A thorough analysis of composition of amphibole mineral requires specialized techniques. EDS, WDS and XRD are the most commonly used methods of identifying amphiboles. These methods can only provide approximate identifications. For example, these techniques cannot distinguish between magnesiohastingsite and magnesio-hornblende. These techniques also don't differentiate between ferro-hornblende or pargasite.
