The Dangers of Exposure to Asbestos
Asbestos was used in thousands of commercial products before it was banned. According research, exposure to asbestos can cause cancer as well as other health issues.
You cannot tell by just looking at a thing if it contains asbestos. It is also impossible to taste or smell it. Asbestos is only detected when the material containing it is broken or drilled.
Chrysotile
At its peak, chrysotile made the majority of the asbestos produced. It was employed in a variety of industries like construction, insulation, and fireproofing. In the event that workers were exposed to this toxic material, they could contract mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma became a problem the use of asbestos has declined significantly. However, traces of it can still be found in common products that we use today.
Chrysotile can be used in a safe manner with a well-thought-out safety and handling plan is put in place. People who handle chrysotile do not at risk of being exposed to a high degree of risk based on the current limit of exposure. The inhalation of airborne fibres has been strongly associated with lung cancer and lung fibrosis. This has been proven to be true for both intensity (dose) and duration of exposure.
In one study, mortality rates were compared between a manufacturing facility that primarily used chrysotile in the manufacture of friction materials and national death rates. It was concluded that for 40 years of processing asbestos chrysotile in low levels of exposure, there was no significant increase in mortality in this particular factory.
In contrast to other forms of asbestos, chrysotile fibres tend to be shorter. They are able to penetrate the lungs and enter the bloodstream. They are more likely to cause health problems than fibres with longer lengths.
It is extremely difficult for chrysotile fibres to be a threat to the air or pose any health risk when mixed with cement. The fibre cement products are extensively used across the globe particularly in buildings like hospitals and schools.
Research has proven that chrysotile has a lower chance to cause illness than amphibole asbestos, such as amosite and crocidolite. Amphibole types like these are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile gets mixed with cement, it creates a strong, flexible building product that can withstand harsh weather conditions and other environmental hazards. It is also easy to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed.
Amosite
Asbestos is a grouping of fibrous silicates that are found in a variety of rock formations. It is classified into six groups which include amphibole (serpentine) and Tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.
Asbestos minerals consist of long, thin fibers that vary in length from fine to broad. They can also be straight or curled. They can be found in nature as bundles or individual fibrils. Asbestos minerals are also found in powder form (talc) or mixed with other minerals and sold as vermiculite and talcum powder which 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 of 20th century, when it was used in shipbuilding, insulation, fireproofing and other construction materials. The majority of occupational exposures involved asbestos fibres borne by air, but certain workers were exposed to vermiculite or talc that was contaminated as well as to fragments of asbestos-bearing rocks (ATSDR, 2001). Exposures varied according to industry, time and geographic location.
The exposure to asbestos at work is mostly caused by inhalation. However there have been instances of workers being exposed by contact with their skin or through eating foods contaminated with asbestos. Asbestos is only present in the environment due to natural weathering of mined ores and the deterioration of products contaminated with asbestos like insulation, car brakes and clutches and ceiling and floor tiles.
There is growing evidence that amphibole fibers that are not commercially available could also be carcinogenic. These are the fibres that are not the tightly woven fibrils of the serpentine and amphibole minerals, but instead are flexible, loose and needle-like. These fibres can be found in mountain sandstones, cliffs and sandstones in a variety of countries.
Asbestos enters the environment mainly in the form of airborne particles, however it can also be absorbed 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 and disposal in landfill sites). Asbestos contamination in ground and surface waters is primarily caused through natural weathering. However it can also be caused anthropogenically, such as by the milling and mining of asbestos-containing materials, demolition and dispersal, and the removal of contaminated dumping material in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary reason for illness among those exposed to it in their job.
Crocidolite
Inhalation exposure to asbestos - www.autogenmotors.com - is the most frequent way people are exposed dangerous fibres, which can be absorbed into the lungs and cause serious health problems. Mesothelioma, asbestosis, and other illnesses are caused by asbestos fibres. Exposure to fibers can occur in other ways, too like contact with contaminated clothing, or building materials. The dangers of this kind of exposure are higher when crocidolite (the asbestos in the blue form, is involved. Crocidolite is smaller and more fragile fibers that are easy to breathe in and may lodge deeper in lung tissue. It has been associated with a higher number of mesothelioma-related cases than any other form of asbestos.
The six main types are chrysotile and amosite. Amosite and chrysotile are the most commonly used types of asbestos, and comprise 95 percent of all commercial asbestos in use. The other four types haven't been as extensively used, but they may still be found in older buildings. They are less dangerous than amosite or chrysotile, but they can still be a risk when mixed with other minerals, or when mined close to other mineral deposits, such as vermiculite and talc.
Numerous studies have revealed the connection between stomach cancer and asbestos compensation exposure. However, the evidence is contradictory. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95% CI: 0.7-3.6) for all workers exposed to asbestos and others have reported an SMR of 1.24 (95% CI: 0.76-2.5) for those who work in chrysotile mines and mills.
IARC The IARC, also known as the International Agency for Research on Cancer has classified all types of asbestos as carcinogenic. All asbestos types can cause mesothelioma but the risks vary depending on the amount of exposure, the type of asbestos is involved and the length of time that exposure lasts. The IARC has recommended that avoiding all forms of asbestos should be the highest priority since this is the most safe option for people. However, if someone has been exposed to asbestos in the past and suffer from a condition such as mesothelioma and other respiratory ailments, they should seek guidance from their GP or NHS 111.
Amphibole
Amphiboles are groups of minerals that can create prism-like or needle-like crystals. They are a type inosilicate mineral made up of two chains of SiO4 molecules. They usually have a monoclinic crystal system, although some have an orthorhombic structure. 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. Tetrahedrons may be separated by strips of octahedral sites.
Amphibole minerals are found in metamorphic and igneous rocks. They are typically dark and hard. Due to their similarity in strength and color, they can be difficult for some people to distinguish from the pyroxenes. They also share a corresponding pattern of cleavage. However their chemistry allows an array of compositions. The various amphibole mineral groups are identified by their chemical compositions and asbestos crystal structures.
The five types of asbestos in the amphibole family include amosite, anthophyllite and chrysotile, crocidolite, and actinolite. Each type 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 a brownish to yellowish hue and is made primarily of magnesium and iron. This type was used to make cement and insulation materials.
Amphibole minerals are challenging to analyze due to their an intricate chemical structure and many substitutions. Therefore, a detailed analysis of their composition requires specialized techniques. The most popular methods to identify amphiboles are EDS, WDS, and XRD. However, these methods only provide approximate identifications. For instance, they cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques do not distinguish between ferro-hornblende and pargasite.
