The Dangers of Exposure to Asbestos Asbestos was used in thousands of commercial products before it was banned. According research, exposure to asbestos can cause cancer as well as other health problems. You can't tell if something has asbestos just by looking at it and you won't be able to taste or smell it. Asbestos can only be detected when materials containing it are broken or drilled. Chrysotile At its peak, chrysotile made up for 99percent of the asbestos created. It was employed in a variety of industries like construction insulation, fireproofing, and insulation. Unfortunately, if workers were exposed for long periods to this toxic substance, they could develop mesothelioma as well as other asbestos related diseases. Fortunately, the use of this harmful mineral has diminished drastically since mesothelioma awareness started to increase in the 1960's. It is still found in many of the products we use today. Chrysotile is safe to use provided you have a comprehensive safety and handling plan in place. It has been discovered that at the current controlled exposure levels, there is no danger to the people working with the substance. The inhalation of airborne fibres has been strongly associated with lung fibrosis and lung cancer. This has been proven to be true for both intensity (dose) and time of exposure. In one study mortality rates were compared between a facility that used a large proportion of Chrysotile for the production of friction materials and national death rates. The study found that, after 40 years of converting low levels of chrysotile there was no significant rise in mortality rates in this factory. Chrysotile fibres are typically shorter than other forms of asbestos. They can penetrate the lungs and enter the bloodstream. They are therefore more likely to cause health issues over longer fibres. When chrysotile mixes with cement, it is extremely difficult for the fibres to become airborne and pose any health risk. Fibre cement products are extensively used in various parts of the world, including schools and hospitals. Research has revealed that amphibole asbestos, such as amosite, crocidolite, or crocidolite, is less likely than chrysotile in causing disease. Amphibole asbestos kinds have been the main cause of mesothelioma and other asbestos-related illnesses. When chrysotile is mixed in with cement, it creates an extremely durable and flexible building product that can withstand harsh weather conditions 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 refers to a set of silicate minerals with fibrous structure that occur naturally in certain kinds of rock formations. It is divided into six groups that include amphibole (serpentine) and the tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite. federal way asbestos lawyer consist of thin, long fibers that range in length from fine to broad. They can be curled or straight. They are found in nature in the form of individual fibrils or bundles with splaying ends referred to as a fibril matrix. Asbestos can also be found in a powder form (talc), or mixed with other minerals in order to create talcum powder or vermiculite. 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 other construction materials. Most occupational exposures were airborne asbestos fibres, but certain workers were exposed to toxic talc or vermiculite and to pieces of asbestos-bearing rock (ATSDR, 2001). Exposures varied according to industry, time and geographical location. Most asbestos exposures that workers were exposed to was caused by inhalation, however certain workers were exposed through contact with skin or by eating food contaminated with asbestos. Asbestos is only found in the environment because of natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles, car brakes and clutches as well as insulation. There is evidence emerging that amphibole fibers that are not commercially available could also be carcinogenic. These fibres are not tightly weaved like the fibrils that are found in amphibole and serpentine but are instead loose, flexible, and needle-like. These fibres are found in the mountains and cliffs of several countries. Asbestos gets into the environment primarily in the form of airborne particles, however it can also be absorbed into water and soil. This can be caused by 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 largely associated with natural weathering. However, it has also been caused by anthropogenic activities like milling and mining demolition and dispersal asbestos-containing materials and the disposal of contaminated dumping ground in landfills (ATSDR 2001). Inhalation exposure to airborne asbestos fibres remains the main cause of illness among people who are exposed to asbestos on a daily basis. Crocidolite Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can infiltrate the lung, causing serious health problems. These include mesothelioma and asbestosis. The exposure to asbestos fibres could be experienced in other ways, like contact with contaminated clothing or building materials. This kind of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is smaller and more fragile fibers that are easier to inhale and can lodge deeper in lung tissue. It has been linked to a larger number of mesothelioma related cases than any other form of asbestos. The six major types of asbestos are chrysotile amosite and tremolite. They are epoxiemite, tremol anthophyllite and actinolite. Chrysotile and amosite are the most commonly used forms of asbestos, and comprise 95% of commercial asbestos currently used. The other four types of asbestos haven't been as extensively used, but they may still be present in older buildings. They aren't as hazardous as amosite or chrysotile, but they can still be dangerous when combined with other minerals or when mined near other naturally occurring mineral deposits such as talc and vermiculite. Numerous studies have revealed an connection between asbestos exposure and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. The evidence is not conclusive. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95% C.I. 0.76-2.5) for workers working in chrysotile mining and mills. The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma but the risks vary depending on how much exposure, what type of asbestos is involved and how long exposure lasts. The IARC has advised that the prevention of all asbestos types is the most important thing to do, as this is the safest option for people. However, if a person has been exposed to asbestos in the past and suffer from a condition such as mesothelioma, or other respiratory ailments, they should seek guidance from their GP or NHS 111. Amphibole Amphibole is a group of minerals that form long prisms or needlelike crystals. They are a type of inosilicate mineral made up of double chains of SiO4 molecules. They have a monoclinic system of crystals, however 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, which are connected in rings of six. The tetrahedrons are separated each other by octahedral sites that are surrounded by strips. Amphibole minerals are found 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 people 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 different minerals in amphibole can be used to determine their composition. The five types of asbestos in the amphibole family include amosite, anthophyllite and crocidolite. They also include actinolite. Each type of asbestos has its own unique properties. Crocidolite is the most hazardous asbestos type. It has sharp fibers that can be easily inhaled into the lung. Anthophyllite is yellowish to brown in color and is composed of iron and magnesium. The variety was used previously in products such as cement and insulation materials. Amphiboles are a challenge to analyze due to their complicated chemical structure and numerous substitutions. An in-depth analysis of the composition of amphibole mineral requires specialized techniques. EDS, WDS and XRD are the most widely used methods of identifying amphiboles. These methods can only provide approximate identifications. These methods, for instance can't distinguish between magnesio hornblende and hastingsite. Furthermore, these techniques do not distinguish between ferro-hornblende as well as pargasite.
