The Dangers of Exposure to Asbestos Asbestos was used in thousands of commercial products before it was banned. According to research, asbestos exposure can cause cancer as well as other health problems. It is difficult to tell by looking at something if it is made of asbestos. It is also impossible to taste or smell it. Asbestos can only be detected when the materials that contain it are broken, drilled, or chipped. Chrysotile At its peak, chrysotile made the majority of asbestos production. It was employed in a variety of industries like construction, insulation, and fireproofing. If workers are exposed to asbestos, they could develop mesothelioma and other asbestos-related illnesses. Fortunately, the use of this dangerous mineral has decreased significantly since awareness of mesothelioma began to spread in the 1960's. However, trace amounts of it remain in products that we use today. Chrysotile is safe to use provided you have a comprehensive safety and handling program in place. Chrysotile handling workers aren't at risk of being exposed to a high degree of risk based on the current controlled exposure levels. Inhaling airborne fibers has been 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 facility that used a large proportion of chlorosotile to make friction materials and national death rates. The study revealed that after 40 years of manufacturing low levels of chrysotile, there was no significant increase in mortality rates at this facility. Chrysotile fibres tend to be shorter than other forms of asbestos. They can enter the lungs, and even enter the bloodstream. They are therefore more likely to cause health issues than fibres that are longer. When chrysotile gets mixed with cement, it is very difficult for the fibres to air-borne and pose health risks. Fibre cement products have been extensively used all over the world particularly in buildings like hospitals and schools. Research has revealed that amphibole asbestos, like amosite or crocidolite is not as likely than chrysotile in causing diseases. Amphibole asbestos kinds have been the main cause of mesothelioma and other asbestos-related diseases. When chrysotile is mixed in with cement, it forms an extremely durable and flexible building product that can withstand the most extreme weather conditions and other environmental dangers. It is also simple to clean after use. Asbestos fibres can be easily removed by a professional, and then eliminated. Amosite Asbestos refers to a set of silicate fibrous minerals that are found naturally in specific types of rock formations. It is divided into six groups: amphibole (serpentine) and tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are composed of long, thin fibers that range in length from fine to wide. They can be curled or straight. They are present in nature in the form of individual fibrils or bundles with splaying edges called a fibril matrix. 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 like baby powder, face powder and cosmetics. Asbestos was extensively used in the early 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 contaminated vermiculite or talc as well as to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied by industry, time and geographic location. The majority of asbestos exposures that workers were exposed to was due to inhalation, but some workers were also exposed through contact with skin or by eating food contaminated with asbestos. Asbestos is now only found in the environment due to natural weathering of mined ores and the degradation of contaminated products such as insulation, car brakes and clutches, as well as floor and ceiling tiles. There is evidence to suggest that non-commercial amphibole fibers could also be carcinogenic. These are the fibres 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 in a variety of countries. Asbestos can enter the environment in many ways, including as airborne particles. It can also leach out into soil or water. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing wastes in landfill sites) sources. Asbestos contamination of surface and ground water is mostly due to natural weathering. However, it has also been caused by human activities such as milling and mining demolition and dispersal asbestos-containing materials and the disposal of contaminated dumping soils in landfills (ATSDR, 2001). Airborne asbestos fibres are the main cause of illness in people exposed to it in their work. Crocidolite Inhalation exposure is the most frequent method of exposure to asbestos fibres. These fibres can infiltrate the lungs and cause serious health issues. These include mesothelioma and asbestosis. The exposure to asbestos fibres could be triggered in other ways, like contact with contaminated clothing or building materials. The dangers of exposure are more pronounced when crocidolite, a blue form of asbestos, is involved. Crocidolite has smaller, more fragile fibers that are easier to breathe and can be lodged deeper in lung tissue. It has been linked to a higher number of mesothelioma cases than any other type of asbestos. The six major types are chrysotile and amosite. Amosite and chrysotile are the most frequently used types of asbestos and account for 95% of all commercial asbestos in use. The other four have not been as popularly used however, they could be present in older buildings. They aren't as hazardous as chrysotile or amosite but can still be dangerous when mixed with other minerals, or when mined close to other mineral deposits, such as vermiculite and talc. Numerous studies have proven that there is a link between stomach cancer and asbestos exposure. However, the evidence is contradictory. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% CI: 0.7-3.6) for all asbestos-related workers and others have reported an SMR of 1.24 (95% CI: 0.76-2.5) for workers in chrysotile mines and mills. The International Agency for Research on Cancer (IARC) has classified all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma, however, the risk is dependent on how much exposure, the type of asbestos is involved and how long exposure lasts. The IARC has advised that avoid all forms of asbestos is the most important thing to do since this is the best option for people. If someone has been exposed to asbestos in the past and suffer from an illness such as mesothelioma, or other respiratory conditions it is recommended that they seek advice from their physician or NHS 111. Amphibole Amphibole is a class of minerals that form long prisms or needle-like crystals. They are a type of inosilicate mineral composed of double chains of molecules of SiO4. worcester asbestos attorney have a monoclinic structure in their crystals but some also have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains comprise (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. The tetrahedrons are separated from one another by strips of octahedral sites. Amphiboles are present in metamorphic and igneous rock. They are usually dark-colored and tough. Due to their similarity of hardness and color, they can be difficult for some people to differentiate from the pyroxenes. They also share a corresponding pattern of cleavage. However, their chemistry allows for the use of a variety of compositions. The various minerals within amphibole can be identified by their chemical compositions and crystal structures. Amphibole asbestos is comprised of chrysotile as well as the five asbestos types amosite anthophyllite (crocidolite), amosite (actinolite) and amosite. Each type of asbestos comes with distinct characteristics. Crocidolite is among the most dangerous asbestos kind. It has sharp fibers that are easily inhaled into the lung. Anthophyllite has a brownish to yellowish color and is made primarily of magnesium and iron. It was previously used in products such as cement and insulation materials. Amphiboles can be difficult to study because of their complex chemical structure and numerous substitutions. A thorough analysis of the composition of amphibole minerals is a complex process that requires specialized methods. The most common methods for identifying amphiboles are EDS, WDS, and XRD. These methods are only able to provide approximate identifications. For example, these techniques can't distinguish between magnesio hastingsite and magnesio-hornblende. In addition, these techniques can not distinguish between ferro-hornblende and pargasite.
