The Dangers of Exposure to Asbestos

Before it was banned, asbestos was widely used in commercial products. Research has shown that exposure to asbestos can cause cancer and other health problems.

It is impossible to determine if a product contains asbestos by looking at it, and you are unable to smell or taste it. It is only visible when asbestos-containing materials are drilled, chipped or broken.

Chrysotile

At the height of its use, chrysotile made up 99% of asbestos production. It was utilized in a variety of industries which included construction, fireproofing, and insulation. If workers are exposed to asbestos, they are likely to develop mesothelioma as well as other asbestos-related illnesses. Since the 1960s, when mesothelioma was first becoming a concern, the use of asbestos has been reduced significantly. However, traces of it are still found in common products that we use today.

Chrysotile is safe to use provided you have a comprehensive safety and handling program in place. It has been found that at the present exposure levels, there is no unneeded risk to the people who handle it. Lung fibrosis, lung cancer and mesothelioma have been strongly linked to breathing airborne respirable fibres. This has been confirmed for intensity (dose) as well as duration of exposure.

One study that examined the operation of a factory that utilized almost exclusively chrysotile to manufacture friction materials, compared mortality rates in this factory with national death rates. The study revealed that after 40 years of processing at low levels of chrysotile, there was no significant increase in mortality in this factory.

In contrast to other forms of asbestos, chrysotile fibres tend to be smaller. They can pass through the lungs and enter the bloodstream. They are more likely to cause health problems than longer fibres.

It is extremely difficult for chrysotile fibers to be airborne or pose any health risk when mixed with cement. Fibre cement products are used extensively throughout the world particularly in structures like hospitals and schools.

Research has proven that chrysotile is less likely to cause disease than amphibole asbestos such as crocidolite and amosite. These amphibole kinds have been the main cause of mesothelioma as well as other asbestos-related illnesses. When chrysotile is combined with cement, it forms an extremely durable and flexible building product that can withstand extreme weather conditions and other environmental dangers. It is also easy to clean after use. Asbestos fibres can easily be removed by a professional and then safely taken away.

Amosite

Asbestos is a term used to describe a class of fibrous silicate minerals that naturally occur in certain kinds of rock formations. It is divided into six groups which include amphibole (serpentine) and Tremolite (tremolite) anthophyllite (crocidolite) and anthophyllite.

Asbestos minerals are made up of thin, long fibres that vary in length, ranging from very fine to wide and straight to curled. These fibers are found in nature as individual fibrils or bundles with splaying ends referred to as fibril matrix. Asbestos can also be found in powder form (talc) or combined with other minerals in order to create talcum powder or vermiculite. They are used extensively in consumer products such as baby powder, cosmetics and face powder.

Asbestos was extensively used in the first two thirds of the 20th century to construct shipbuilding, insulation, fireproofing, and various other construction materials. The majority of asbestos exposures for work were in the air, however certain workers were also exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied according to the industry, time frame and geographic location.

Most of the asbestos exposures at work were because of inhalation, but some workers were also exposed by skin contact or by eating food contaminated with asbestos. Asbestos can only be found in the environment because of natural weathering and degrading of products that are contaminated like ceiling and floor tiles cars, brakes and clutches, and insulation.

There is evidence to suggest that amphibole fibres from non-commercial sources could also be carcinogenic. These are the fibres that do not have the tight woven fibrils of the amphibole or serpentine minerals but instead are loose, flexible and needle-like. These fibers can be found in the mountains and cliffs of several countries.

Asbestos enters the environment mainly in the form of airborne particles, however it can also leach into water and soil. This is a result of both natural (weathering and erosion of asbestos-bearing rocks) and anthropogenic (disintegration and disposal of asbestos-containing wastes at landfill sites) sources. Asbestos contamination of ground and surface water is largely associated with natural weathering, but it has also been triggered by anthropogenic activities such as mining and milling, demolition and fpcom.co.kr dispersal of platteville asbestos-containing materials as well as the disposal of contaminated dumping ground in landfills (ATSDR, 2001). Asbestos fibres that are emitted from the air are the main cause of illness in people exposed to asbestos in their work.

Crocidolite

Exposure to asbestos through inhalation is the most frequent method by which people are exposed harmful fibres that can then enter the lungs and cause serious health issues. This includes asbestosis and mesothelioma. Exposure to fibers can occur in a variety of ways, for example, contact with contaminated clothing or construction materials. The risks of exposure are greater when crocidolite which is the blue form of asbestos is involved. Crocidolite is smaller and more fragile fibers that are easy to breathe in and may lodge deeper into lung tissue. It has been associated with a higher number of mesothelioma-related cases than any other type of asbestos.

The six main types of asbestos are chrysotile amosite, epoxiemite, tremolite anthophyllite and actinolite. Amosite and chrysotile are two of the most frequently used types of asbestos. They comprise 95% of the asbestos used in commercial construction. The other four asbestos types are not as well-known, but can still be found in older structures. They are less dangerous than amosite and chrysotile, however they can pose a risk when mixed with other asbestos minerals or when mined in close proximity to other naturally occurring mineral deposits, like vermiculite or talc.

Numerous studies have proven the connection between stomach cancer and asbestos exposure. The evidence is contradictory. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95 percent of the time CI: 0.7-3.6) for all workers exposed to asbestos while other studies have reported an SMR of 1.24 (95 percent C.I. 0.76-2.5) for workers working in chrysotile mining and mills.

The International Agency for Research on Cancer (IARC) has classed all asbestos types as carcinogenic. All asbestos types can cause mesothelioma but the risk is different based on how much exposure is taken, what type of asbestos is involved, and the length of time that exposure lasts. IARC has declared that the best option for people is to avoid all types of asbestos. If you have been exposed to asbestos and suffer from a respiratory disorder or mesothelioma, you should seek advice from your physician or NHS111.

Amphibole

Amphibole is a group of minerals that form long prisms or needlelike crystals. They are a type inosilicate mineral composed of double chains of molecules of SiO4. They are a monoclinic system of crystals, but some 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 that are joined in rings of six. The tetrahedrons are separated each other by strips of octahedral sites.

Amphibole minerals are found in metamorphic and igneous rocks. They are usually dark and hard. They are sometimes difficult to differentiate from pyroxenes as they share similar hardness and color. They also share a similar Cleavage. Their chemistry permits a wide range of compositions. The various mineral groups within amphibole are identified by their chemical compositions and crystal structures.

The five types of asbestos belonging to the amphibole family are amosite, anthophyllite and chrysotile as well as crocidolite and actinolite. Each type of asbestos has its own unique properties. The most dangerous form of asbestos, crocidolite, is made up of sharp fibers that are easy to inhale into the lung. Anthophyllite ranges from brown to yellowish in color vimeo.com and is composed of magnesium and iron. This kind of material was used to create cement and insulation materials.

Amphibole minerals are hard to analyze due to their complex chemical structures and a variety of substitutions. A thorough analysis of composition of amphibole minerals requires special techniques. The most common methods of identifying amphiboles include EDS, WDS, and XRD. These methods are only able to provide approximate identifications. For example, these techniques can't distinguish between magnesio hastingsite and magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro hornblende and pargasite.
