The Dangers of Exposure to Asbestos Asbestos was found in thousands of commercial products before it was banned. According research, exposure to asbestos can cause cancer as well as other health problems. It is difficult to tell if something is asbestos-containing by looking at it and you can't taste or smell it. It is only visible when materials containing asbestos are chipped, drilled or broken. Chrysotile At its peak, chrysotile made up for 99percent of the asbestos that was produced. It was used in many industries including construction insulation, fireproofing, and insulation. In the event that workers were exposed to the toxic substance, they could develop mesothelioma or other asbestos related diseases. Thankfully, the use of this harmful mineral has diminished significantly since mesothelioma awareness began to grow in the 1960's. It is still found in many of the products we use in the present. Chrysotile is safe to use if a thorough safety and handling plan is in place. It has been found that at the present exposure levels, there is no unneeded risk to the people working with the substance. The inhalation of airborne particles has been found to be strongly linked with lung fibrosis and lung cancer. This has been proven to be true for both intensity (dose) and the duration of exposure. In one study mortality rates were compared between a manufacturing facility which used almost exclusively Chrysotile for the production of friction materials and the national death rate. It was concluded that for the 40 years of processing asbestos chrysotile at a low level of exposure there was no signifi cant extra mortality in the factory. As opposed to other forms of asbestos, chrysotile fibres tend to be smaller. They can pass through the lungs and then enter the bloodstream. They are therefore more likely to cause health problems than fibres that are longer. When chrysotile is mixed into cement, it's very difficult for the fibres to breathe and pose any health risk. Fibre cement products are utilized in many areas of the world including hospitals and schools. Research has shown that amphibole asbestos like amosite, crocidolite, or crocidolite, is less likely to cause diseases. These amphibole types are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile and cement are mixed with cement, a tough and flexible material is created that is able to 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 taken away. Amosite Asbestos refers to a group of silicate minerals with fibrous structure that naturally occur in certain kinds of rock formations. It is classified into six groups that include amphibole (serpentine) and the tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are composed of thin, long fibres that range in length from extremely thin to broad and straight to curled. These fibres are found in nature as individual fibrils or as bundles with splaying edges called fibril matrix. Asbestos is also found in powder form (talc), or combined with other minerals to form vermiculite or talcum powder. They are extensively used in consumer products, including baby powder, cosmetics, and face powder. Asbestos was widely used during the first two thirds of the 20th century for shipbuilding as well as insulation, fireproofing and various other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, but some workers were also exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied from industry to industry, era to and geographic location. Exposure to asbestos in the workplace is mainly due to inhalation. However there are workers who have been exposed through skin contact or by eating food items contaminated with asbestos. Asbestos is found in the environment because of natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles cars, brakes and clutches, and insulation. There is evidence emerging that amphibole fibres from non-commercial sources could also be carcinogenic. These are fibers that are not the tightly weaved fibrils of amphibole or serpentine minerals but instead are flexible, loose and needle-like. These fibers can be found in mountain sandstones, cliffs and sandstones in a variety of countries. Asbestos can be found in the environment in the form of airborne particles, however it can also be absorbed into soil and water. This occurs both from natural (weathering and erosion of asbestos-bearing rocks) and ananthropogenic (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination in surface and ground waters is primarily due to natural weathering. However, it has also been caused by anthropogeny, such as through milling and mining of asbestos-containing materials, demolition and dispersal, and the removal of contaminated dumping material in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the most significant cause of illness in people 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, causing serious health problems. These include mesothelioma and asbestosis. Exposure to asbestos fibres can occur in different ways, such as contact with contaminated clothes or building materials. This kind of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are softer and less brittle making them more palatable to breathe. They also can get deeper into lung tissues. It has been linked to a greater number of mesothelioma related cases than any other form of asbestos. The six primary types are chrysotile and amosite. The most commonly used forms of asbestos are epoxiemite and chrysotile which together comprise the majority of commercial asbestos employed. The other four types haven't been as widely utilized but they can be present in older buildings. They are less harmful than chrysotile and amosite, but they could pose a threat when mixed with other asbestos minerals, or when mined in close proximity to other mineral deposits, such as vermiculite or talc. Numerous studies have shown an association between stomach cancer and asbestos exposure. However the evidence isn't conclusive. Some researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% 95% confidence interval: 0.7-3.6) for all asbestos-related workers as well as an SMR of 1.24 (95% CI: 0.76-2.5) for workers in chrysotile mines and mills. IARC The IARC, which is the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All kinds of asbestos can cause mesothelioma and other health issues, but the risks vary according to the amount of exposure that people are exposed to, the type of asbestos used as well as the length of their exposure and the manner in which it is inhaled or ingested. IARC has stated that the best choice for people is to avoid all forms of asbestos. If you've been exposed in the past to asbestos and suffer from a respiratory disorder or mesothelioma, then you should see your physician or NHS111. Amphibole Amphiboles are groups of minerals which can form prism-like or needle-like crystals. vermont asbestos lawyer are an inosilicate minerals made of double chains of SiO4 molecules. They are 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 composed of (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. Tetrahedrons may be separated by strips of octahedral site. Amphibole minerals are common in metamorphic and igneous rocks. They are usually dark and hard. Due to their similarity in hardness and color, they can be difficult for some to differentiate from pyroxenes. They also share a similar the cleavage pattern. However their chemistry permits the use of a variety of compositions. The chemical compositions and crystal structure of the various minerals in amphibole can be used to identify them. The five types of asbestos that belong to the amphibole group include chrysotile, anthophyllite, amosite, crocidolite, and actinolite. The most widely used asbestos type is chrysotile, each variety is unique in its own way. The most dangerous type of asbestos, crocidolite is made up of sharp fibers that are easy to breathe into the lung. Anthophyllite has a brownish to yellowish color and is made mostly of iron and magnesium. It was previously used in cement-based products and insulation materials. Amphibole minerals are challenging to analyze due to their a complicated chemical structure and many substitutions. Therefore, a thorough analysis of their composition requires special methods. EDS, WDS and XRD are the most popular methods for identifying amphiboles. However, these methods can only provide approximate identifications. For instance, they are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. In addition, these techniques can not distinguish between ferro-hornblende or pargasite.
