The Dangers of Exposure to AsbestosAsbestos was found in thousands of commercial products prior to when it was banned. Research shows that exposure to asbestos can cause cancer and other health issues.It is difficult to tell if something contains asbestos by looking at it and you won’t be able to taste or smell it. Asbestos can only be identified when the material containing it is broken or drilled.ChrysotileAt its height, chrysotile provided for 95% of the asbestos created. It was used by many industries which included construction insulation, fireproofing and insulation. If workers were exposed to this toxic material, they could contract mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma was first becoming a concern, the use of asbestos has been drastically reduced. However, trace amounts are still found in many of the products we use in the present.Chrysotile is safe to use if you have a comprehensive safety and handling plan in place. It has been found that at the current controlled exposure levels, there is no undue risk to the workers working with it. Lung cancer, lung fibrosis and mesothelioma have been strongly linked to breathing airborne respirable fibres. This has been proven to be true for both intensity (dose) and time of exposure.In one study mortality rates were compared between a manufacturing facility which used largely Chrysotile for the production of friction materials and the national death rate. The study concluded that, after 40 years of manufacturing low levels of chrysotile there was no significant increase in mortality rates at this facility.Chrysotile fibres are typically shorter than other forms of asbestos. They can penetrate the lungs and then enter the bloodstream. They are more likely to cause health problems over longer fibres.When chrysotile is mixed into cement, it’s extremely difficult for the fibres to become airborne and pose any health risk. Fibre cement products are extensively utilized in many areas of the world, including schools and hospitals.Research has shown that chrysotile is less prone to cause illness than amphibole asbestos such as crocidolite and amosite. These amphibole types have been the primary cause of mesothelioma as well as other asbestos-related diseases. When the cement and chrysotile are combined with cement, a tough, flexible product is created that can withstand extreme weather conditions and environmental hazards. It is also easy to clean after use. Professionals can safely remove asbestos fibres once they have been removed.AmositeAsbestos refers to a group of silicate mineral fibrous that occur naturally in certain types of rock formations. It is divided into six groups: amphibole (serpentine) and Tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.Asbestos minerals comprise thin, long fibers that range in length from fine to wide. They can be curled or straight. They are found in nature in bundles, or as individual fibrils. Asbestos can also be found in a powder form (talc) or combined with other minerals in order to create vermiculite or talcum powder. They are used extensively in consumer products such as baby powder, cosmetics, and even face powder.Asbestos was widely used during the early two-thirds of the 20th century to construct construction of ships insulation, fireproofing, insulation and various other construction materials. Most occupational exposures were asbestos fibres borne by air, but some workers were exposed to vermiculite and talc that had been contaminated, and to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied from industry industry, era to and even geographical location.The majority of asbestos-related exposures in the workplace were due to inhalation. However, el monte asbestos attorney were also exposed via skin contact or by eating food contaminated with asbestos. Asbestos is only found in the natural environment due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles as well as car brakes and clutches as well as insulation.It is becoming evident that non-commercial amphibole fibres may also be carcinogenic. They are not tightly knit like the fibrils found in serpentine and amphibole, but are instead loose, flexible, and needle-like. They can be found in mountains, sandstones and cliffs in a variety of countries.Asbestos can enter the environment in a variety ways, including through airborne particles. It can also leach out into water or soil. This can be due to both natural (weathering of asbestos-bearing rock) and anthropogenic causes (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination in ground and surface waters is primarily caused through 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 disposal of contaminated waste in landfills (ATSDR 2001). The inhalation of asbestos fibres is the most common cause of illness for people exposed to asbestos at work.CrocidoliteInhalation exposure to asbestos is the most common way people are exposed to harmful fibres that can then get into the lungs and cause serious health issues. These include mesothelioma and asbestosis. Exposure to fibers can occur in other ways as well like contact with contaminated clothing, or building materials. This kind of exposure is more dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is a smaller, more fragile fibers that are easier to breathe and can be lodged deeper into lung tissue. It has been associated with a higher number of mesothelioma cases than any other form of asbestos.The six main types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. Amosite and chrysotile are two of the most commonly used types of asbestos, and comprise 95% of all commercial asbestos currently used. The other four asbestos types are not as common, but may still be present in older structures. They are less dangerous than amosite or chrysotile, but they can still be a danger when combined with other minerals or when mined near other mineral deposits like vermiculite and talc.Numerous studies have revealed an association between asbestos exposure and stomach cancer. A number of studies have confirmed that asbestos exposure is linked to stomach. The evidence isn’t unanimous. Some researchers have reported an SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95% C.I. 0.76-2.5) for workers working in chrysotile mining and mills.IARC The IARC, also known as the International Agency for Research on Cancer has classified all forms of asbestos carcinogenic. All asbestos types can cause mesothelioma but the risk is different based on how much exposure, what kind of asbestos is involved and the length of time that exposure lasts. IARC has stated that the best choice for individuals is to stay clear of all types of asbestos. If you’ve been exposed to asbestos and suffer from a respiratory disorder or mesothelioma, then you should seek advice from your physician or NHS111.AmphiboleAmphibole is one of the minerals that form long prisms or needlelike crystals. They are a type of inosilicate mineral composed of double chains of molecules of SiO4. They have a monoclinic arrangement 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 which are connected in rings of six. The tetrahedrons are separated one another by octahedral sites in strips.Amphiboles are found in metamorphic and igneous rock. They are typically dark-colored and hard. They can be difficult to distinguish from pyroxenes since they share similar hardness and color. They also have a comparable the cleavage. Their chemistry permits a wide variety of compositions. The chemical compositions and crystal structure of the different mineral groups found in amphibole may be used to identify them.Amphibole asbestos comprises chrysotile and the five asbestos types amosite anthophyllite (crocidolite), amosite (actinolite), and amosite. Each variety of asbestos has its own distinctive properties. Crocidolite is the most dangerous asbestos type. It contains sharp fibers that are easily inhaled into the lungs. Anthophyllite is brown to yellowish in color and is composed of iron and magnesium. This type of stone was once used in cement-based products and insulation materials.Amphiboles are difficult to analyze due to their complex chemical structure and the numerous substitutions. A thorough analysis of composition of amphibole mineral requires specialized techniques. EDS, WDS and XRD are the most common methods for identifying amphiboles. However, these methods only provide approximate identifications. For instance, they cannot differentiate between magnesio-hastingsite and magnesio-hornblende. In addition, these techniques can not distinguish between ferro hornblende and pargasite.
