The Dangers of Exposure to Asbestos
Before it was banned asbestos was used in thousands commercial products. Studies have shown that exposure to asbestos can cause cancer and other health issues.
It is not possible to tell by simply looking at a thing if it's made of asbestos. Neither can you taste or smell it. It is only visible when materials containing asbestos are drilled, chipped or broken.
Chrysotile
At its peak, chrysotile accounted for 95% of the asbestos produced. It was employed in many industries including construction insulation, fireproofing, as well as insulation. However, if workers were exposed to this toxic material, they may develop mesothelioma as well as other asbestos related diseases. Since the 1960s, when mesothelioma began to become an issue the use of asbestos has been reduced significantly. However, trace amounts of it remain in common products that we use in the present.
Chrysotile can be used in a safe manner when a thorough safety and handling plan is put into place. It has been discovered that, at today's controlled exposure levels, there is no unneeded risk to the people handling the substance. 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 the duration of exposure.
A study that looked at an industrial facility that used almost exclusively chrysotile for manufacturing friction materials, compared the mortality rates of this factory with national death rates. The study found that after 40 years of manufacturing low levels of chrysotile, there was no significant increase in mortality in this factory.
Chrysotile fibres are typically shorter than other forms of asbestos. They are able to penetrate the lungs and then enter the bloodstream. They are therefore more likely to cause health issues over longer fibres.
It is extremely difficult for chrysotile fibres be airborne or pose any health risk when mixed with cement. Fibre cement products are widely used in various parts of the world, including schools and hospitals.
Research has shown that chrysotile has a lower chance to cause disease than amphibole asbestos like amosite and crocidolite. Amphibole types like these are the primary cause of mesothelioma and other asbestos-related diseases. When cement and chrysotile mix with cement, a tough and flexible product is created that can withstand extreme environmental hazards and weather conditions. It is also easy to clean after use. Asbestos fibres are easily removed by a professional and then safely disposed of.
Amosite
Asbestos is a grouping of fibrous silicates that are found in certain types rock formations. It is classified into six groups that include amphibole (serpentine) and the tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.
Asbestos minerals consist of thin, long fibers that vary in length from fine to broad. They can be curled or straight. They are found in nature as individual fibrils or bundles with splaying edges called a fibril matrix. Asbestos can also be found in powder form (talc), or mixed with other minerals to form vermiculite or talcum powder. These are widely used as consumer goods, such as baby powder, cosmetics and facial powder.
The heaviest use of asbestos was in the early two-thirds of the 20th century, when it was used in insulation, shipbuilding, fireproofing and other construction materials. Most occupational exposures were to asbestos fibres in the air, however certain workers were exposed to contaminated vermiculite or talc and also to fragments of asbestos-bearing rocks (ATSDR 2001). Exposures varied from industry to industry, era to era and geographic location.
Exposure to asbestos in the workplace is mostly caused by inhalation. However, some workers have been exposed through skin contact or by eating food items contaminated with asbestos. Asbestos can only be found in the environment because of natural weathering and degrading of products that are contaminated, such as ceiling and floor tiles, car brakes and clutches, and insulation.
It is becoming increasingly apparent that non-commercial amphibole fibers could also be carcinogenic. These are fibres that do not have the tight weaved fibrils of serpentine and amphibole minerals, but instead are loose, flexible and needle-like. These fibers are found in mountain sandstones, cliffs and sandstones of many countries.
Asbestos can be absorbed into the environment in a variety ways, such as in airborne particles. It is also able to leach into soil or water. This can be caused by both natural (weathering of asbestos-bearing rock) and anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of surface and ground waters is primarily caused by natural weathering. However it is also caused by anthropogeny, such as through the mining and milling of asbestos-containing materials demolition and dispersal and the disposal of contaminated waste in landfills (ATSDR 2001). Inhalation exposure to asbestos fibers is the primary cause of illness among people exposed to it occupationally.
Crocidolite
Inhalation exposure is the most frequent method of exposure to asbestos fibres. These fibres can enter the lung which can cause serious health issues. These include asbestosis and mesothelioma. Exposure to asbestos fibres can occur in a variety of ways, for example, contact with contaminated clothing or materials. This type of exposure is particularly dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe in and may lodge deeper into lung tissue. It has been associated with a higher number of mesothelioma cases than any other type of asbestos.
The six major types of asbestos are chrysotile amosite, epoxiemite, tremolite anthophyllite and actinolite. The most commonly used asbestos types are epoxiemite and chrysotile which together comprise the majority of commercial asbestos used. The other four asbestos types are not as widespread, but they can still be present in older structures. They aren't as hazardous as amosite or chrysotile, but they can still be a danger when mixed with other minerals or when mined near other naturally occurring mineral deposits like talc and vermiculite.
Numerous studies have demonstrated an association between stomach cancer and asbestos exposure. The evidence is not conclusive. waterbury asbestos lawyer 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 and others have reported an SMR of 1.24 (95 percent CI: 0.76-2.5) for those who work in chrysotile mines and mills.
IARC The IARC, which is the International Agency for Research on Cancer, has classified all types of asbestos carcinogenic. All asbestos types can cause mesothelioma but the risk is different based on the amount of exposure, the type of asbestos is involved, and how long exposure lasts. IARC has declared that the best option for people is to stay clear of all forms of asbestos. If someone has been exposed to asbestos in the past and are suffering from a disease such as mesothelioma or other respiratory conditions, they should seek guidance from their doctor or NHS 111.
Amphibole
Amphibole is a group of minerals that form long prisms or needlelike crystals. They are an inosilicate mineral made up of double chains of SiO4 molecules. They have a monoclinic system of crystals, however some exhibit 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 can be separated by strips of octahedral sites.
Amphiboles are present in metamorphic and igneous rock. They are typically dark-colored and hard. Due to their similarity in hardness and color, they can be difficult for some to differentiate from pyroxenes. They also share a corresponding cleavage. Their chemistry allows for a variety of compositions. The chemical compositions and crystal structure of the different minerals in amphibole can be used to identify them.
The five asbestos types in the amphibole family include chrysotile, anthophyllite, amosite as well as crocidolite and actinolite. While the most popular form of asbestos is chrysotile each type has distinct characteristics. The most hazardous type of asbestos, crocidolite, is made up of sharp fibers that are easy to breathe into the lung. Anthophyllite is a brownish to yellowish hue and is made mostly of iron and magnesium. This type was used to make 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 specialized methods. The most commonly used methods for identifying amphiboles is EDS, WDS, and XRD. These methods can only provide approximate identifications. These techniques, for example, cannot distinguish between magnesio hornblende and magnesio hastingsite. These techniques also do not distinguish between ferro-hornblende and pargasite.
