The Dangers of Exposure to Asbestos Asbestos was used in a variety of commercial products before it was banned. According to research, exposure to asbestos can cause cancer as well as other health issues. You cannot tell if something is asbestos-containing simply by looking at it and you cannot taste or smell it. Asbestos is only detected when materials containing it are broken or drilled. Chrysotile At its height, chrysotile was responsible for 90% of the asbestos produced. It was used by many industries, including construction insulation, fireproofing and insulation. If workers were exposed to this harmful substance, they could develop mesothelioma and other asbestos-related diseases. Thankfully, the use this toxic mineral has decreased significantly since mesothelioma awareness began to increase in the 1960's. It is still found in many products we use today. Chrysotile can be safely used in the event that a thorough safety and handling plan is put into place. It has been found that at the current controlled exposure levels, there is no unneeded risk to the people handling the substance. Inhaling airborne fibers has been strongly associated with lung fibrosis and lung cancer. This has been proven both for intensity (dose) as well as the duration of exposure. One study that studied a factory that used almost all chrysotile as its friction materials compared mortality rates in this factory with national death rates. It was found that, for 40 years of processing asbestos chrysotile in low levels of exposure, there was no significant additional mortality in this factory. Chrysotile fibres are usually shorter than other forms of asbestos. They can pass through the lungs and pass into the bloodstream. They are more likely to cause health problems than fibres with longer lengths. It is very difficult for chrysotile fibers to be inhaled or to pose a health risk when mixed with cement. Fibre cement products have been extensively used all over the world particularly in structures such as schools and hospitals. Research has proven that amphibole asbestos like amosite or crocidolite is less likely than chrysotile to cause disease. These amphibole types are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile is combined with cement, it creates a strong, flexible construction product that is able to withstand severe conditions in the weather and other environmental hazards. It is also easy to clean after use. Professionals can safely get rid of asbestos fibres after they have been removed. Amosite Asbestos is a term used to describe a class of silicate fibrous minerals that occur naturally in certain kinds of rock formations. It is divided into six groups including amphibole (serpentine), tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals consist of thin, long fibers that range in length from extremely thin to broad and straight to curled. They are found in nature in bundles, or as individual fibrils. Asbestos minerals can be found as a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite and are used in consumer products, such as baby powder cosmetics, face powder and other. Asbestos was widely used during the first two thirds of the 20th century for construction of ships as well as insulation, fireproofing and various other construction materials. The majority of asbestos-related exposures in the workplace occurred in the air, but some workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied by industry, time period and geographic location. Exposure to asbestos in the workplace is mainly due to inhalation. However certain workers have been exposed through contact with skin or eating contaminated foods. Asbestos is only found in the natural environment due to natural weathering and degrading of products that are contaminated like ceiling and floor tiles as well as car brakes and clutches as well as insulation. There is emerging evidence that amphibole fibres from non-commercial sources could also be carcinogenic. These are fibers that don't form the tightly knit fibrils of the amphibole and serpentine minerals but instead are flexible, loose and needle-like. These fibres are found in the mountains and cliffs of several countries. Asbestos may enter the environment in many ways, such as in airborne particles. It can also be absorbed into soil or water. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing wastes in landfill sites) sources. Asbestos contamination of ground and surface water is largely associated with natural weathering. However, it has also been caused by human activities such as mining and milling demolition and dispersal asbestos-containing material and the disposal of contaminated dumping ground in landfills (ATSDR 2001). Inhalation exposure to airborne asbestos fibres is still the primary cause of illness for people exposed to asbestos in the workplace. Crocidolite Inhalation exposure to asbestos is the most popular way people are exposed to harmful fibres. They can then be inhaled and cause serious health problems. Mesothelioma, asbestosis, and other diseases can be caused by asbestos fibres. The exposure to asbestos fibres could occur in different ways, such as contact with contaminated clothing or building materials. The dangers of exposure are heightened when crocidolite, the blue form of asbestos is involved. Crocidolite fibers are thinner and more fragile and therefore easier to inhale. They can also lodge deeper in lung tissue. It has been linked to a larger number of mesothelioma cases than any other type of asbestos. The six primary types are chrysotile, amosite and chrysotile. The most well-known forms of asbestos are epoxiemite and chrysotile, which together make up 95% all commercial asbestos used. The other four asbestos types aren't as prevalent, but could still be present in older structures. provo asbestos lawsuit are not as hazardous as chrysotile and amosite, but they could be a risk when mixed with other asbestos minerals, or when mined close to other mineral deposits, like vermiculite or talc. Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. However the evidence is not conclusive. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers. However, others have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for workers in chrysotile mills and mines. IARC The IARC, also known as the International Agency for Research on Cancer, has classified all forms of asbestos as carcinogenic. All kinds of asbestos may cause mesothelioma and other health issues, however 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 consumed. The IARC has recommended that avoid all forms of asbestos should be the highest priority because this is the most secure option for people. If you've been exposed to asbestos and are suffering 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 a kind of inosilicate mineral composed of double chains of SiO4 molecules. They have a monoclinic system of crystals, but some have an orthorhombic shape. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are made up of (Si,Al)O4 Tetrahedrons which are connected in rings of six. Tetrahedrons may be separated by strips of octahedral site. Amphiboles can be found in metamorphic and igneous rock. They are typically 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 cut. However their chemistry allows the use of a variety of compositions. The different amphibole mineral groups are identified by their chemical compositions as well as crystal structures. The five asbestos types in the amphibole family include amosite, anthophyllite, crocidolite, and actinolite. While the most popular asbestos type is chrysotile each type has its own unique characteristics. The most dangerous type of asbestos, crocidolite, is composed of sharp fibers that are easy to breathe into the lung. Anthophyllite is brown to yellowish in color and is made up of magnesium and iron. It was previously used in products such as cement and insulation materials. Amphibole minerals are challenging to study because of their an intricate chemical structure and many substitutions. A detailed analysis of the composition of amphibole minerals is a complex process that requires specialized methods. The most commonly used methods for identifying amphiboles is EDS, WDS, and XRD. However, these methods only provide approximate identifications. For instance, these techniques can't distinguish between magnesio-hornblende and hastingsite. Furthermore, these techniques do not distinguish between ferro hornblende and pargasite.
