The Dangers of Exposure to Asbestos Asbestos was found in thousands of commercial products prior to when it was banned. According to research, exposure to asbestos can cause cancer, as well as other health issues. It is not possible to tell by simply looking at something whether it contains asbestos. You cannot smell or taste it. It is only discovered in the event that asbestos-containing products are drilled, chipped or broken. Chrysotile At the height of its use, chrysotile made the majority of asbestos production. It was employed in many industries such as construction, fireproofing, and insulation. In the event that workers were exposed to the toxic material, they could contract mesothelioma as well as other asbestos related diseases. Fortunately, the use of this dangerous mineral has decreased significantly since mesothelioma awareness began to increase in the 1960's. However, trace amounts of it can still be found in products that we use today. Chrysotile is safe to use in the event that you have a complete safety and handling program in place. It has been proven that at the present exposure levels, there isn't an unneeded risk to the people working with the substance. ontario asbestos law firm , lung cancer and mesothelioma are all associated with breathing in airborne respirable fibres. This has been confirmed for both the intensity (dose) and the duration of exposure. In one study, mortality rates were compared between a factory that primarily used Chrysotile for the production of friction materials and the national death rate. It was concluded that for 40 years of processing asbestos chrysotile in low levels of exposure there was no signifi cant extra mortality in the factory. Chrysotile fibres are typically shorter than other types of asbestos. They can penetrate the lungs and enter the bloodstream. They are therefore more likely to cause health problems than longer fibres. When chrysotile is mixed into cement, it is very difficult for the fibres to air-borne and pose any health risk. Fibre cement products are extensively utilized in many areas of the world including hospitals and schools. Research has shown that amphibole asbestos like crocidolite or amosite is less likely than chrysotile to cause diseases. These amphibole varieties are the main cause of mesothelioma, and other asbestos-related diseases. When chrysotile gets mixed with cement, it forms a strong, flexible construction product that can withstand extreme weather conditions and other environmental hazards. It is also very easy to clean up after use. Professionals can safely remove asbestos fibres once they have been removed. Amosite Asbestos is a term used to describe a class of fibrous silicate minerals that occur naturally in certain kinds of rock formations. It is classified into six groups: amphibole (serpentine), the tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are composed of thin, long fibers that vary in length from extremely thin to broad and straight to curled. These fibers are found in nature in bundles or individual fibrils. Asbestos can also be found in a powder form (talc), or combined with other minerals to form vermiculite or talcum powder. These are widely used as consumer products, such as baby powder cosmetics, and even face powder. Asbestos was heavily used in the early two-thirds of the 20th century for construction of ships, insulation, fireproofing, and other construction materials. The majority of asbestos exposures for work were in the air, however certain workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied from industry industry, era era and even geographical location. Exposure to asbestos at work is mostly caused by inhalation. However there have been instances of workers being exposed via skin contact or through eating foods contaminated with asbestos. Asbestos is only present in the environment from natural weathering of mined ores and the degrading of contaminated materials like insulation, car brakes and clutches as well as ceiling and floor tiles. It is becoming apparent that amphibole fibers that are not commercially available could also be carcinogenic. These fibers aren't woven like the fibrils found in amphibole or serpentine, but are instead loose as well as flexible and needle-like. These fibres are found in the mountains and cliffs of several countries. Asbestos is able to enter the environment in a variety ways, such as in airborne particles. It can also be absorbed into soil or water. This is caused by both natural (weathering of asbestos-bearing rock) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground water is typically a result of natural weathering, but has also been caused by anthropogenic activities like milling and mining demolition and dispersal asbestos-containing materials, and the removal of contaminated dumping soil in landfills (ATSDR, 2001). Airborne asbestos fibres are the main reason for illness among those exposed to asbestos during their job. Crocidolite Inhalation exposure to asbestos is the most popular way people are exposed to the harmful fibres, which could be absorbed into the lungs and cause serious health problems. These include asbestosis and mesothelioma. Exposure to asbestos fibers can occur in different ways, including contact with contaminated clothes or building materials. This kind of exposure is particularly dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite is smaller and more fragile fibers that are easy to breathe in and may lodge deeper in lung tissue. It has been associated with more mesothelioma cancer cases than other asbestos types. The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. The most commonly used forms of asbestos are epoxiemite as well as chrysotile which together make up the majority of commercial asbestos employed. The other four forms haven't been as popularly used however, they could be found in older buildings. They are not as hazardous as amosite and chrysotile, but they could pose a threat when mixed with other asbestos minerals or when mined close to other mineral deposits, such as vermiculite or talc. Many studies have discovered an connection between exposure to asbestos and stomach cancer. Several studies have found a link between asbestos exposure and stomach. The evidence is contradictory. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95 percent 95% CI: 0.76-2.5) for workers working in chrysotile mining and mills. IARC, the International Agency for Research on Cancer has classified all types of asbestos as carcinogenic. All asbestos types can cause mesothelioma, but the risks vary depending on the amount of exposure is taken, what type of asbestos is involved and how long the exposure lasts. IARC has declared that the best choice for people is to avoid all types of asbestos. If you've been exposed to asbestos and are suffering from a respiratory disorder or mesothelioma condition, then you should consult your GP or NHS111. Amphibole Amphibole is a class of minerals that form long prism or needlelike crystals. They are a type inosilicate mineral composed of double chains of SiO4 molecules. They typically have a monoclinic crystal system, although some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are composed of (Si,Al)O4 Tetrahedrons that are joined in rings of six. The tetrahedrons are separated from each other by octahedral sites that are surrounded by strips. Amphiboles are present in metamorphic and igneous rock. They are typically dark and hard. They are sometimes difficult to differentiate from pyroxenes as they share similar hardness and colors. They also share a corresponding cleavage pattern. Their chemistry permits a wide variety of compositions. The chemical compositions and crystal structure of the various mineral groups found in amphibole may be used to determine their composition. The five types of asbestos belonging to the amphibole family are amosite, anthophyllite and chrysotile, crocidolite, and actinolite. Each variety of asbestos has its own distinct properties. The most dangerous type of asbestos, crocidolite, is composed of sharp fibers that are easy to breathe into the lung. Anthophyllite can range from yellow to brown in color and is made up of magnesium and iron. This kind of material was used to create cement and insulation materials. Amphiboles are difficult to analyze due to their complicated chemical structure and the numerous substitutions. Therefore, a thorough analysis of their composition requires specialized methods. EDS, WDS and XRD are the most widely used methods of identifying amphiboles. However, these methods can only give approximate identifications. For instance, these techniques are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro-hornblende and pargasite.
