The Dangers of Exposure to Asbestos
Asbestos was a component in thousands of commercial products before it was banned. Research suggests that exposure to asbestos can cause cancer and other health problems.
alhambra asbestos lawyer is difficult to tell by taking a look at something if it is made of asbestos. You cannot smell or taste it. It is only visible when asbestos-containing materials are drilled, chipped or broken.
Chrysotile
At its height, chrysotile comprised the majority of the asbestos produced. It was used in many industries including construction, insulation, and fireproofing. If workers are exposed to asbestos, they may develop mesothelioma as well as other asbestos-related diseases. Fortunately, the use this hazardous mineral has declined drastically since mesothelioma awareness started to spread in the 1960’s. It is still found in many products we use today.
Chrysotile can be safely used in the event that a thorough safety and handling plan is in place. It has been determined that at the present exposure levels, there isn’t an undue risk to the workers handling it. Lung fibrosis, lung cancer and mesothelioma have been strongly connected to breathing in airborne respirable fibres. This has been proven to be true for both the intensity (dose) and time of exposure.
One study that examined a factory that used almost exclusively chrysotile in the production of friction materials compared mortality rates in this factory with national death 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.
As opposed to other forms of asbestos, chrysotile fibers tend to be shorter. They are able to enter the lungs, and then pass through the bloodstream. They are therefore more likely to cause health problems than longer fibres.
When chrysotile is mixed into cement, it’s very difficult for the fibres to air-borne and cause health hazards. Fibre cement products have been extensively used across the globe particularly in structures such as schools and hospitals.
Research has revealed that amphibole asbestos such as amosite or crocidolite is less likely to cause disease. These amphibole forms have been the primary source of mesothelioma, as well as other asbestos-related diseases. When chrysotile and cement are mixed, a durable product is produced which is able to withstand the most extreme environmental hazards and weather conditions. It is also easy to clean up after use. Asbestos fibers can be easily removed by a professional and then safely taken away.
Amosite
Asbestos refers to a group of silicate mineral fibrous which are found naturally in a variety of kinds of rock formations. It is comprised of six general groups: amphibole, serpentine, tremolite, anthophyllite and crocidolite (IARC, 1973).
Asbestos minerals are made up of thin, long fibers that range in length, ranging from very fine to broad and straight to curled. These fibres are found in nature as individual fibrils or bundles that have splaying ends, referred to as a fibril matrix. Asbestos minerals are also found in powder form (talc) or mixed with other minerals and sold as talcum powder and vermiculite that are widely used in consumer products, such as baby powder cosmetics, face powder, and baby powder.
The heaviest use of asbestos was in the first two-thirds period of the twentieth century where it was used in shipbuilding, insulation, fireproofing, and other construction materials. Most occupational exposures were to asbestos fibres borne by air, but some workers were exposed to contaminated vermiculite or talc as well as to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied from industry industry, era era and geographic location.
Exposure to asbestos in the workplace is mostly due to inhalation. However there have been instances of workers being exposed through contact with skin or eating food that is contaminated. Asbestos can only be found in the natural environment due to natural weathering and degrading of contaminated materials like ceiling and floor tiles, car brakes and clutches as well as insulation.
It is becoming clear that non-commercial amphibole fibers could also be carcinogenic. These are the fibres that do not have the tight interwoven fibrils that are found in the amphibole or serpentine minerals but instead are loose, flexible and needle-like. These fibers can be found in mountain sandstones, cliffs and sandstones of a variety of countries.
Asbestos is able to enter the environment in a variety ways, including through airborne particles. It can also leach out into soil or water. This is caused by both natural (weathering of asbestos-bearing rock) as well as anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of ground and surface water is mostly a result of natural weathering, however it has also been caused by human activities such as milling and mining demolition and dispersal of 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 among people exposed to it in their occupation.
Crocidolite
Exposure to asbestos through inhalation is the most frequent way people are exposed to dangerous fibres, which can then be inhaled and cause serious health problems. These include mesothelioma and asbestosis. Exposure to asbestos fibres can occur in different ways, including contact with contaminated clothes or building materials. This type of exposure is more dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite is smaller and more fragile fibers that are easy to breathe in and can get deeper in lung tissue. It has been linked to more mesothelioma-related cases than other types of asbestos.
The six main types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. The most commonly used asbestos types are chrysotile and epoxiemite, which together make up 95% all commercial asbestos employed. The other four asbestos types are not as widespread, but they can still be found in older structures. They are less hazardous than amosite and chrysotile, however they could be a risk when combined with other asbestos minerals or when mined in close proximity to other mineral deposits, such as talc or vermiculite.
Numerous studies have revealed an association between stomach cancer and asbestos exposure. The evidence isn’t unanimous. Certain researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all asbestos-related workers as well as an SMR of 1.24 (95 percent C.I. 0.76-2.5) for those working in chrysotile mines and mills.
The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All kinds of asbestos may cause mesothelioma and other health issues, however the risks vary according to how much exposure people are exposed to, the type of asbestos used, the duration of their exposure, and the manner in the way that it is breathed in or consumed. The IARC has advised that avoiding all forms of asbestos should be the highest priority since this is the safest option for those who are exposed. If someone has been exposed to asbestos in the past and are suffering from an illness such as mesothelioma, or other respiratory conditions it is recommended that they seek advice from their doctor or NHS 111.
Amphibole
Amphibole is a group of minerals that form long prism or needlelike crystals. They are a type inosilicate mineral made up of double chains of SiO4 molecules. They usually have a monoclinic crystal structure however some may have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains consist of (Si,Al)O4 Tetrahedrons, which are connected in rings of six. The tetrahedrons can be separated by strips of octahedral sites.
Amphiboles are found in both igneous and metamorphic rock. They are usually dark and hard. Due to their similarity of hardness and colour, they can be difficult for some to differentiate from pyroxenes. They also have a similar Cleavage. However their chemistry permits the use of a variety of compositions. The chemical compositions and crystal structures of the different mineral groups in amphibole could be used to determine their composition.
Amphibole asbestos includes chrysotile and the five types of asbestos: amosite, anthophyllite (crocidolite) amosite (actinolite) and amosite. While the most commonly used asbestos type is chrysotile; each has its own unique characteristics. The most dangerous type of asbestos, crocidolite is composed of sharp fibers that are simple to breathe into the lung. Anthophyllite is a brownish to yellowish color and is made mostly of iron and magnesium. This kind of stone was used to create cement and insulation materials.
Amphiboles are a challenge to analyze due to their complicated chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires special techniques. The most common methods of identifying amphiboles include EDS, WDS, and XRD. These methods can only provide approximate identifications. For instance, these techniques are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. These techniques also cannot distinguish between ferro-hornblende and pargasite.
