The Dangers of Exposure to Asbestos
Before it was banned, asbestos was widely used in commercial products. According to research, exposure to asbestos can cause cancer and many other health issues.
It is not possible to tell by simply looking at something whether it's made of asbestos legal. It is also impossible to smell or taste it. It is only visible in the event that asbestos-containing products are drilled, chipped or broken.
Chrysotile
At its peak, chrysotile accounted for 99% of the asbestos made. It was employed in many industries which included construction insulation, fireproofing, and construction. In the event that workers were exposed to this toxic substance, they could develop mesothelioma and other asbestos-related diseases. Thankfully, the use this harmful mineral has diminished dramatically since mesothelioma awareness began to increase in the 1960's. However, it is still present in trace amounts. are still present in products that we use today.
Chrysotile is safe to use in the event that a thorough safety and handling plan is put into place. It has been discovered that at the present exposure levels, there isn't an danger to those handling it. Lung fibrosis, lung cancer and mesothelioma are all connected to breathing in airborne respirable fibres. This has been proven to be true for both intensity (dose) and duration of exposure.
In one study, mortality rates were compared between a facility which used almost exclusively Chrysotile in the production of friction materials and the national death rate. The study found that after 40 years of converting low levels of chrysotile, there was no significant rise in mortality at this factory.
Chrysotile fibres are usually 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.
It is very difficult for chrysotile fibrous to be in the air or pose a health risk when mixed with cement. The fibre cement products are extensively used across the globe particularly in buildings such as schools and hospitals.
Research has shown that amphibole asbestos such as amosite, crocidolite, or crocidolite, is less likely than chrysotile in causing diseases. Amphibole asbestos forms have been the primary source of mesothelioma, as well as other asbestos-related illnesses. When chrysotile mixes with cement, it creates a strong, flexible building product that can withstand extreme conditions in the weather and other environmental hazards. It is also easy to clean after use. Professionals can safely dispose of asbestos fibres after they have been removed.
Amosite
Asbestos refers to a set of silicate mineral fibrous that are found naturally in specific types of rock formations. It is classified into six groups including amphibole (serpentine) and tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.
Asbestos minerals are made up of thin, long fibers that range in length from fine to broad. They can be curled or straight. These fibres can be found in nature in bundles, or as individual fibrils. Asbestos is also found in a powder form (talc), or mixed with other minerals to form talcum powder or vermiculite. They are extensively used in consumer products such as baby powder, cosmetics and facial powder.
Asbestos was widely used during the first two thirds of the 20th century for shipbuilding, insulation, fireproofing, and other construction materials. The majority of occupational exposures to asbestos fibres occurred in the air, but certain workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied from industry to industry, era era, and geographical location.
The exposure to asbestos in the workplace is usually caused by inhalation. However, some workers have been exposed through contact with skin or through eating foods contaminated with asbestos. Asbestos is now only found in the environment due to natural weathering of mined ores and deterioration of contaminated products like insulation, car brakes and clutches and ceiling and floor tiles.
There is emerging evidence that amphibole fibers that are not commercially available could also be carcinogenic. These are fibers that do not form the tightly woven fibrils of the serpentine and amphibole minerals, but instead are flexible, loose and asbestos needle-like. These fibers are found in the cliffs, mountains and sandstones of many countries.
Asbestos can enter the environment in a variety of ways, including through airborne particles. It can also leach out into water or soil. This is a result of both natural (weathering and erosion of asbestos-bearing rocks) and anthropogenic (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination of surface and ground water is mostly a result of natural weathering, but has also been caused by human activities such as mining and milling demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated dumping soil in landfills (ATSDR, 2001). Asbestos fibres that are emitted from the air are the primary cause of illness among people exposed to asbestos in their work.
Crocidolite
Inhalation 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 problems. Mesothelioma, asbestosis, and other diseases are caused by asbestos fibres. The exposure to asbestos can happen in different ways too including contact with contaminated clothing or building materials. The dangers of this kind of exposure are more pronounced when crocidolite, the asbestos that is blue is involved. Crocidolite is smaller and more fragile fibers, which are easier to breathe in and can get deeper in lung tissue. It has been linked to more mesothelioma cases than other asbestos types.
The six major types are chrysotile as well as amosite. The most popular forms of asbestos are chrysotile and epoxiemite, which together make up 95% all commercial asbestos used. The other four asbestos types aren't as well-known, but can still be found in older structures. They are less harmful than amosite and chrysotile. However, they could be a risk when combined with other asbestos minerals or when mined close to other naturally occurring mineral deposits, like talc or vermiculite.
Many studies have discovered an connection between asbestos case exposure and stomach cancer. Several studies have found a link between asbestos exposure and stomach. However there is no conclusive evidence. Some 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 those who work in chrysotile mines and mills.
The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All types of asbestos can cause mesothelioma as well as other health issues, however the risks are different based on the amount of exposure that people are exposed to, the kind of asbestos involved as well as the duration of exposure and the way in which it is inhaled or ingested. The IARC has recommended that avoid all forms of asbestos should be the top priority, as this is the safest option for those who are exposed. If you have been exposed to asbestos and suffer from a respiratory illness or mesothelioma, then you should seek advice from your physician or NHS111.
Amphibole
Amphiboles comprise a variety of minerals that may create prism-like or needle-like crystals. They are a type inosilicate mineral made up of double chains of SiO4 molecules. They usually have a monoclinic structure in their crystals however some may 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 which are connected in rings of six. The tetrahedrons are separated one another by octahedral sites that are surrounded by strips.
Amphiboles are found in metamorphic and igneous rock. They are typically dark and hard. Due to their similarity in hardness and colour, they can be difficult for some people to differentiate from Pyroxenes. They also share a similar design of cleavage. Their chemistry permits a wide variety of compositions. The various mineral groups within amphibole are identified by their chemical compositions and crystal structures.
The five asbestos types in the amphibole family include chrysotile, anthophyllite, amosite, crocidolite, and actinolite. Each variety of asbestos has its own unique properties. The most dangerous type of asbestos, crocidolite, is composed of sharp fibers that are easy to inhale into the lung. Anthophyllite is yellowish to brown in color and is composed of magnesium and iron. This type of stone was once used in products such as cement and insulation materials.
Amphibole minerals are challenging to analyze due to their a complicated chemical structure and a variety of substitutions. Therefore, a detailed analysis of their composition requires special techniques. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods only give approximate identifications. For instance, they can't distinguish between magnesio hastingsite and magnesio-hornblende. These techniques also do not distinguish between ferro-hornblende and pargasite.
