The Dangers of Exposure to Asbestos Before it was banned, asbestos was still used in a variety of commercial products. Research shows that exposure to asbestos can cause cancer and other health issues. You cannot tell by just looking at something if it is made of asbestos. Also, you cannot taste or smell it. Asbestos can only be detected when materials containing it are broken, drilled, or chipped. Chrysotile At its peak, chrysotile made up for 99percent of the asbestos made. It was employed in a variety of industries, including construction, insulation, and fireproofing. However, if workers were exposed for long periods to this toxic material, they could develop mesothelioma and other asbestos-related diseases. Since the 1960s, when mesothelioma was first becoming a problem the use of asbestos has declined significantly. It is still present in a variety of products we use in the present. Chrysotile is safe to use in the event that you have a complete safety and handling program in place. It has been found that, at today's controlled exposure levels, there isn't an danger to those handling it. Lung cancer, lung fibrosis and mesothelioma have all been found to be strongly linked to breathing in airborne respirable fibres. This has been proven for both intensity (dose) and time span of exposure. In one study, mortality rates were compared among a factory that primarily used Chrysotile for the production of friction materials and national death rates. It was discovered that, for 40 years of preparing asbestos chrysotile at a low level of exposure There was no significant extra mortality in the factory. Chrysotile fibres are usually shorter than other types of asbestos. They can pass through the lungs, and then pass through the bloodstream. This makes them more prone to causing health consequences than longer fibres. It is extremely difficult for chrysotile fibrous to be airborne or pose any health risk when mixed with cement. The fibre cement products are used extensively throughout the world particularly in structures like hospitals and schools. Research has proven that amphibole asbestos, such as amosite or crocidolite is not as likely than chrysotile in causing diseases. Amphibole asbestos forms have been the primary cause of mesothelioma as well as other asbestos-related diseases. When the cement and chrysotile are combined, a durable product is produced that is able to stand up to extreme environmental hazards and weather conditions. It is also easy to clean after use. Asbestos fibres are easily removed by a professional and safely taken away. Amosite Asbestos refers to a group of silicate fibrous minerals that are found naturally in specific types of rock formations. It is divided into six groups: amphibole (serpentine), tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite. Asbestos minerals are made up of long, thin fibers that vary in length from extremely fine to wide and straight to curled. These fibres are found in nature as individual fibrils or as bundles with splaying edges called fibril matrix. Asbestos minerals are also found as a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder and are used in consumer products like baby powder, face powder and cosmetics. The largest asbestos use occurred during the first two-thirds of the twentieth century where it was used in shipbuilding, insulation, fireproofing, and other construction materials. richardson asbestos law firm of asbestos exposures for work were in the air, however certain 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 because of inhalation. However there have been instances of workers being exposed through skin contact or by eating food items contaminated with asbestos. Asbestos is found in the air due to natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles cars, brakes and clutches, as well as insulation. There is evidence emerging that amphibole fibers that are not commercially available could also be carcinogenic. They are not tightly weaved like the fibrils that are found in amphibole and serpentine they are loose elastic, flexible, and needle-like. They can be found in the cliffs, mountains and sandstones of many countries. Asbestos gets into the environment primarily in the form of airborne particles, however it can also leach into soil and water. This can be triggered by both natural (weathering of asbestos-bearing rock) as well as anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination in ground and surface waters is primarily caused by natural weathering. However it is also caused by humans, such as through milling and mining of asbestos-containing materials, demolition and dispersal, and the removal of contaminated dumping material in landfills (ATSDR 2001). The inhalation of asbestos fibres remains the main reason for illness among those exposed to it occupationally. Crocidolite Inhalation exposure is the most commonly used method of exposure to asbestos fibres. The fibres can penetrate the lungs, causing serious health problems. These include asbestosis and mesothelioma. Exposure to asbestos fibers can be experienced in other ways, including contact with contaminated clothing or building materials. The dangers of this kind of exposure are more pronounced when crocidolite which is the asbestos that is blue, is involved. Crocidolite is a smaller, more fragile fibers that are easy to breathe in and may lodge deeper in lung tissue. It has been linked to a larger number of mesothelioma-related cancers than any other type of asbestos. The six primary types are chrysotile as well as amosite. The most popular asbestos types are epoxiemite and chrysotile which together make up the majority of commercial asbestos used. The other four types of asbestos haven't been as widely used but they can be found in older buildings. They are less hazardous than amosite or chrysotile but still be dangerous when mixed with other minerals, or when mined close to other mineral deposits, such as vermiculite and talc. Numerous studies have revealed an connection between asbestos exposure and stomach cancer. The evidence is contradictory. Some researchers have reported an SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers. However, others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for workers in mines and chrysotile mills. IARC, the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All forms of asbestos could cause mesothelioma and other health issues, however the risks differ based on the amount of exposure individuals are exposed to, the kind of asbestos used and the duration of their exposure and the manner in the way that it is breathed in or consumed. The IARC has advised that abstaining from all asbestos forms is the most important thing to do because this is the most secure option for individuals. However, if a person has been exposed to asbestos in the past and suffer from a disease such as mesothelioma, or other respiratory ailments it is recommended that they seek advice from their physician or NHS 111. Amphibole Amphibole is one of the minerals that form long prism or needle-like crystals. They are a type of silicate mineral made up of two chains of molecules of SiO4. They have a monoclinic structure of crystals, however some have an orthorhombic shape. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are made up of (Si,Al)O4 Tetrahedrons, which are connected in rings of six. The tetrahedrons are separated from one another by octahedral sites that are surrounded by strips. Amphiboles are found in metamorphic and igneous rock. They are usually dark-colored and hard. They can be difficult to distinguish from pyroxenes due to their similar hardness and colors. They also share a corresponding Cleavage. Their chemistry can allow for a variety of compositions. The chemical compositions and crystal structures of the different mineral groups found in amphibole may be used to identify them. Amphibole asbestos includes chrysotile and the five asbestos types amosite anthophyllite (crocidolite), amosite (actinolite) and amosite. Each kind of asbestos has its own unique properties. Crocidolite is among the most dangerous asbestos type. It is composed of sharp fibers that can easily be breathed into the lungs. Anthophyllite is a brownish to yellowish hue and is comprised primarily of magnesium and iron. It was previously used in cement-based products and insulation materials. Amphibole minerals are challenging to study because of their an intricate chemical structure and numerous substitutions. An in-depth analysis of the composition of amphibole minerals requires specialized methods. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. However, these methods can only give approximate identifications. For instance, they cannot differentiate between magnesio-hastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro-hornblende as well as pargasite.
