The Dangers of Exposure to Asbestos Before it was banned asbestos was used in a myriad of commercial products. According to studies, exposure to asbestos can cause cancer and a host of other health issues. It is impossible to determine if a product contains asbestos by looking at it, and you won't be able to smell or taste it. Asbestos is only detectable when the substances that contain it are broken or drilled. Chrysotile At its peak, chrysotile made up for 90% of the asbestos produced. It was used in many industries, including construction insulation, fireproofing, and insulation. However, if workers were exposed to the toxic substance, they could develop mesothelioma and other asbestos-related diseases. Thankfully, the use of this harmful mineral has diminished dramatically since mesothelioma awareness began to grow in the 1960's. It is still present in a variety of products we use today. Chrysotile is safe to use provided you have a comprehensive safety and handling program in place. It has been discovered that at the present exposure levels, there isn't an unneeded risk to the people working with the substance. Inhaling airborne fibres is strongly linked to lung cancer and lung fibrosis. This has been confirmed both in terms of intensity (dose) as in the time of exposure. A study that looked at a facility that used nearly exclusively chrysotile to manufacture friction materials compared the mortality rates of this factory with national mortality rates. The study found that, after 40 years of converting low levels of chrysotile there was no significant rise in mortality rates at this facility. In contrast to other forms of asbestos, chrysotile fibers tend to be shorter. They can penetrate the lungs, and even enter the bloodstream. They are therefore more likely to cause health issues over longer fibres. When chrysotile is mixed into cement, it is very difficult for the fibres to become airborne and pose any health risks. Fibre cement products are extensively used in a variety of locations around the world, including schools and hospitals. Research has shown that amphibole asbestos such as amosite or crocidolite is less likely to cause disease. Amphibole types like these are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile and cement are mixed with cement, a tough and flexible product is created which is able to withstand the most extreme environmental hazards and weather conditions. It is also easy to clean after use. Asbestos fibres can be easily removed by a professional and then safely removed. Amosite Asbestos refers to a group of silicate minerals with fibrous structure that naturally occur in certain types of rock formations. It is classified into six groups which include amphibole (serpentine), the tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are composed of long, thin fibres that range in length, ranging from very fine to wide and straight to curled. They are found in nature in the form of individual fibrils or bundles with splaying edges called a fibril matrix. Asbestos can also be found in powder form (talc), or mixed with other minerals in order to create vermiculite or talcum powder. They are extensively used 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 for shipbuilding as well as insulation, fireproofing and various other construction materials. The majority of asbestos exposures for work were in the air, however some workers were also exposed to asbestos-bearing rock fragments and contaminated vermiculite. Exposures varied according to the type of industry, the time period and geographic location. Asbestos exposure in the workplace is mostly caused by inhalation. However there are workers who have been exposed via skin contact or by eating food items contaminated with asbestos. Asbestos can only be found in the environment due to natural weathering and degradation of contaminated products, such as ceiling and floor tiles as well as car brakes and clutches, as well as insulation. It is becoming increasingly apparent that non-commercial amphibole fibres may also be carcinogenic. These fibres are not tightly weaved like the fibrils that are found in amphibole and serpentine, they are loose elastic, flexible, and needle-like. These fibers are found in the mountains, sandstones and cliffs in a variety of countries. Asbestos gets into the environment primarily as airborne particles, but it can also be absorbed into soil and water. This happens both through natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination in ground and surface waters is primarily caused by natural weathering. However, it has also been caused by anthropogeny, such as through mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Airborne asbestos fibres are the primary reason for illness among those who are exposed to it during their job. Crocidolite Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can get into the lungs which can cause serious health issues. These include asbestosis and mesothelioma. Exposure to fibres can occur in other ways, too, such as contact with contaminated clothing or materials. This type of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite fibers are less dense and more fragile, making them easier to breathe. They also can get deeper into lung tissues. It has been associated with more mesothelioma cases than other asbestos types. The six major types are chrysotile as well as amosite. Chrysotile and amosite are the most commonly used types of asbestos. They comprise 95% of all asbestos used in commercial construction. The other four types haven't been as extensively used however they can be found in older buildings. They are less hazardous than chrysotile or amosite but can still be a risk when combined with other minerals or when mined close to other mineral deposits like talc and vermiculite. Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. However, the evidence is contradictory. Certain researchers have cited an SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers, and others have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for workers in chrysotile mines and mills. IARC, the International Agency for Research on Cancer, has classified all forms of asbestos carcinogenic. All types of asbestos can cause mesothelioma or other health issues, although the risks are different based on the amount of exposure that individuals are exposed to, the type of asbestos used as well as the length of their exposure, and the manner in the way that it is breathed in or consumed. IARC has stated that the best choice for people is to avoid all forms of asbestos. If you've been exposed to asbestos and are suffering from respiratory issues or mesothelioma condition, then you should consult your GP or NHS111. Amphibole Amphibole belongs to a group of minerals that form long prism or needle-like crystals. They are a kind of inosilicate mineral composed of double chains of SiO4 molecules. They typically possess a monoclinic crystal system however, some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains contain (Si, Al)O4 tetrahedrons linked together in a series of six tetrahedrons. Tetrahedrons may be separated by strips of octahedral site. Amphiboles are present in both igneous and metamorphic rock. They are usually dark-colored and tough. They are sometimes difficult to distinguish from pyroxenes due to their similar hardness and color. They also share a corresponding pattern of cleavage. However their chemistry allows a wide range of compositions. The various amphibole mineral groups are identified by their chemical compositions as well as crystal structures. Amphibole asbestos is comprised of chrysotile as well as the five types of asbestos amosite anthophyllite (crocidolite) amosite (actinolite), and amosite. Each type of asbestos comes with distinct characteristics. Crocidolite is the most hazardous asbestos type. long beach asbestos lawsuit is made up of sharp fibers that can be easily breathed into the lungs. Anthophyllite is brown to yellowish in color and is composed of iron and magnesium. The variety was used previously in cement and insulation materials. Amphibole minerals can be difficult to study because of their an intricate chemical structure and numerous substitutions. An in-depth analysis of the composition of amphibole mineral requires specialized techniques. The most commonly used methods to identify amphiboles are EDS, WDS, and XRD. These methods are only able to provide approximate identifications. These techniques, for instance can't distinguish between magnesio hornblende and hastingsite. In addition, these techniques can not distinguish between ferro hornblende and pargasite.
