    The Dangers of Exposure to Asbestos

    Before it was banned, asbestos was used in thousands commercial products. According to research, asbestos exposure can cause cancer and a host of other health problems.

    You can't tell if something includes asbestos simply by looking at it and you won't be able to taste or smell it. It is only found when the asbestos-containing materials are drilled, chipped or broken.

    Chrysotile

    At its height, chrysotile provided for 99percent of the asbestos created. It was used by many industries, including construction insulation, fireproofing and insulation. 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 drastically since mesothelioma awareness started to grow in the 1960's. However, it is still present in trace amounts. are still found in many of the products we use today.

    Chrysotile is safe to use when you have a thorough safety and handling plan in place. Personnel handling chrysotile aren't exposed to a significant amount of risk based on the current controlled exposure levels. The inhalation of airborne particles is strongly linked to lung cancer and lung fibrosis. This has been confirmed for intensity (dose) as well as duration of exposure.

    A study that looked at a facility that used nearly exclusively chrysotile in the production of friction materials, compared mortality rates in this facility with national mortality rates. It was found that for 40 years of processing west jordan asbestos chrysotile at low levels of exposure there was no significant extra mortality in the factory.

    Unlike some other forms of asbestos, chrysotile fibres tend to be shorter. They are able to enter the lungs and pass into the bloodstream. They are more likely to cause health problems than longer fibres.

    It is extremely difficult for chrysotile fibrous to be inhaled or to pose a health risk when mixed with cement. Fibre cement products are used in a variety of locations around the world including hospitals and schools.

    Research has demonstrated that amphibole asbestos, like amosite or crocidolite is less likely to cause disease. These amphibole types have been the primary cause of mesothelioma as well as other asbestos-related diseases. When chrysotile is combined with cement, it creates a strong, flexible construction product that is able to withstand severe weather conditions and other environmental hazards. It is also easy to clean after use. Professionals can safely remove asbestos fibres once they have been removed.

    Amosite

    Asbestos refers to a set of silicate minerals with fibrous structure that occur naturally in certain types of rock formations. It is comprised of six general groups: amphibole, serpentine as well as tremolite, anthophyllite, and crocidolite (IARC 1973).

    Asbestos minerals consist of long, thin fibers that range in length from extremely fine to broad and straight to curled. They can be found in nature in bundles, or as individual fibrils. Asbestos minerals are also found in the form of a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite that are widely used in consumer products such as baby powder, face powder and cosmetics.

    Asbestos was widely used during the first two thirds of the 20th century to construct shipbuilding insulation, fireproofing, insulation and other construction materials. The majority of asbestos exposures for work occurred in the air, but certain workers were also exposed to asbestos-bearing rock fragments and vermiculite that was contaminated. Exposures varied according to the type of industry, the time period and geographic location.

    Asbestos exposure in the workplace is mainly caused by inhalation. However, some workers have been exposed via skin contact or through eating foods contaminated with asbestos. Asbestos can be found in the environment from natural weathering of mined ores and the degradation of contaminated products such as insulation, car brakes and clutches as well as ceiling and floor tiles.

    It is becoming clear that non-commercial amphibole fibers can also be carcinogenic. These are fibres are not the tightly woven fibrils of the serpentine and amphibole minerals, but instead are loose, flexible and needle-like. These fibers are found in mountains, sandstones and cliffs of a variety of countries.

    Asbestos is able to enter the environment in a variety ways, including through airborne particles. It is also able to leach into soil or water. This can be caused by both natural (weathering of asbestos-bearing rocks) 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 such as milling and mining demolition and dispersal asbestos-containing materials as well as the disposal of contaminated soils for disposal in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the most significant cause of illness in people who are exposed to it during their work.

    Crocidolite

    Exposure to asbestos through inhalation is the most frequent way people are exposed harmful fibres, which could be absorbed into the lungs and cause serious health problems. This includes asbestosis and mesothelioma. Exposure to asbestos fibres 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 a smaller, more fragile fibers that are easy to breathe in and may lodge deeper into lung tissue. It has been linked to more mesothelioma-related cases than other types of asbestos.

    The six major types are chrysotile, amosite and chrysotile. The most well-known Northampton Asbestos Lawyer types are epoxiemite as well as chrysotile which together make up the majority of commercial asbestos employed. The other four have not been as popularly used, but they may still be found in older buildings. They are less hazardous than chrysotile or amosite but can still be dangerous when mixed with other minerals, or when mined near other naturally occurring mineral deposits, such as talc and vermiculite.

    Numerous studies have proven the connection between stomach cancer and asbestos exposure. However there is no conclusive evidence. Some researchers have cited an overall SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all asbestos-related workers and others have reported an SMR of 1.24 (95% C.I. 0.76-2.5) for those who work in chrysotile mines and mills.

    The International Agency for Research on Cancer (IARC) has classed all asbestos types as carcinogenic. All types of asbestos can cause mesothelioma or other health problems, but the risk is dependent on the amount of exposure individuals are exposed to, the type of asbestos used as well as the duration of exposure and the method by which it is breathed in or consumed. IARC has declared that the best choice for individuals is to stay clear of all forms of asbestos. However, if a person has been exposed to asbestos in the past and suffer from an illness such as mesothelioma or other respiratory ailments it is recommended that they seek advice from their physician or NHS 111.

    Amphibole

    Amphiboles comprise a variety of minerals that can form needle-like or prism-like crystals. They are a type of inosilicate mineral made up of double chains of SiO4 molecules. They typically 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 are composed of (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. The tetrahedrons are separated by strips of octahedral site.

    Amphibole minerals are common in igneous and metamorphic rocks. They are typically dark-colored and northampton asbestos lawyer hard. They are sometimes difficult to distinguish from pyroxenes due to their similar hardness and colors. They also share a similar cleavage. Their chemistry permits a wide variety of compositions. The chemical compositions and crystal structure of the various minerals in amphibole can be used to determine their composition.

    The five types of rochester asbestos lawyer in the amphibole class include amosite, anthophyllite and chrysotile as well as crocidolite and actinolite. Each type of asbestos has its own distinct properties. Crocidolite is the most hazardous asbestos type. It is composed of sharp fibers that can easily be inhaled into the lungs. Anthophyllite is yellowish to brown in color and is composed of magnesium and iron. This type was used to make cement and insulation materials.

    Amphiboles are difficult to analyse due to their complicated chemical structure and the numerous substitutions. A thorough analysis of the composition of amphibole minerals requires specialized techniques. EDS, WDS and XRD are the most common methods of identifying amphiboles. However, these methods can only give approximate identifications. For instance, these techniques cannot differentiate between magnesio-hastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro hornblende and pargasite.
