The Dangers of Exposure to Asbestos

Asbestos was found in thousands of commercial products prior to when it was banned. Research has shown that exposure to asbestos can cause cancer and other health problems.

It is difficult to tell by taking a look at something 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 height, chrysotile comprised up 99% of the asbestos produced. It was widely used in industries, including construction insulation, fireproofing and insulation. If workers were exposed to this harmful substance, they could develop mesothelioma, as well as other asbestos-related diseases. Fortunately, the use of this hazardous mineral has declined dramatically since mesothelioma awareness began to spread in the 1960's. However, traces of it are still present in many of the products we use today.

Chrysotile is safe to use in the event that you have a complete safety and handling plan in place. Workers handling chrysotile are not at risk of being exposed to a high degree of risk at the present limits of exposure. Lung cancer, lung fibrosis and mesothelioma are all associated with breathing in airborne respirable fibres. This has been proven for both the intensity (dose) and time span of exposure.

In one study mortality rates were compared between a manufacturing facility that primarily used chrysotile in the manufacture of friction materials and the national death rate. The study concluded that, after 40 years of processing at low levels of chrysotile, there was no significant rise in mortality rates in this factory.

As opposed to other forms of asbestos, chrysotile fibres tend to be shorter. They can pass through the lungs and enter the bloodstream. This makes them much more prone to cause negative effects than fibrils with a longer length.

It is extremely difficult for chrysotile fibers to be in the air or pose a health risk when mixed with cement. Fibre cement products have been extensively used across the globe, especially in buildings such as schools and hospitals.

Research has proven that amphibole asbestos, such as amosite or crocidolite is not as likely to cause diseases. These amphibole varieties are the main cause of mesothelioma, and other asbestos-related diseases. When cement and chrysotile are mixed and cured, a tough and flexible material is created that is able to withstand extreme weather conditions and environmental hazards. It is also easy to clean after use. Professionals can safely remove asbestos fibres once they have been removed.

Amosite

Asbestos is a category of fibrous silicates that are found in various types of rock formations. It consists of six general groups: serpentine, amphibole anthophyllite, tremolite, anthophyllite, crocidolite (IARC 1973).

Asbestos minerals are made up of long, thin fibers that vary in length, ranging from very fine to broad and straight to curled. They are found in nature as individual fibrils or bundles that have splaying ends, referred to as fibril matrix. Asbestos minerals are also found in powder form (talc) or mixed with other minerals and sold as talcum powder and asbestos lawsuit vermiculite which are widely used in consumer products such as baby powder, face powder and cosmetics.

Asbestos was used extensively in the first two thirds of the 20th century for construction of ships, insulation, fireproofing, and various other construction materials. Most occupational exposures were asbestos fibres that were borne in the air, but some workers were exposed toxic talc or vermiculite, and to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied according to the type of industry, the time period and geographical location.

The majority of occupational exposures to asbestos were because of inhalation, but some workers were also exposed through skin contact or by eating food contaminated with asbestos. Asbestos is found in the air due to natural weathering and degrading of contaminated materials, such as ceiling and floor tiles cars, brakes and clutches, as well as insulation.

It is becoming clear that amphibole fibers that are not commercially available could also be carcinogenic. These are fibres are not the tightly interwoven fibrils that are found in the amphibole or serpentine minerals but instead are loose, flexible and needle-like. These fibres can be found in the mountains, sandstones and cliffs from a variety of nations.

Asbestos is able to enter the environment in a variety of ways, such as in airborne particles. It is also able to leach into soil or water. This is caused by both natural (weathering of asbestos-bearing rocks) and anthropogenic sources (disintegration of asbestos lawsuit; similar web page,-containing wastes as well as 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 mining and milling, demolition and dispersal of asbestos lawyer-containing materials, and the removal of contaminated dumping soil in landfills (ATSDR, 2001). The inhalation of asbestos fibers is the primary cause of illness in people exposed to asbestos at work.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos law fibres. These fibres can get into the lungs and cause serious health issues. These include mesothelioma and asbestosis. Exposure to asbestos fibres can occur in different ways too including contact with contaminated clothing or construction materials. This type of exposure is more hazardous when crocidolite (the blue form of asbestos) is involved. Crocidolite is a smaller, more fragile fibers that are easy to breathe in and may lodge deeper in lung tissue. It has been associated with more mesothelioma cancer cases than other types of asbestos.

The six main types are chrysotile, amosite and chrysotile. The most popular asbestos types are chrysotile and epoxiemite, which together make up the majority of commercial asbestos used. The other four forms haven't been as widely utilized however, they could be present in older buildings. They are less hazardous than chrysotile and amosite, but they can pose a risk when mixed with other asbestos minerals, or when mined close to other mineral deposits, like vermiculite or talc.

Numerous studies have proven that there is a link between stomach cancer and asbestos exposure. The evidence isn't conclusive. Some researchers have reported an overall SMR (standardized mortality ratio) of 1.5 (95% 95% confidence interval: 0.7-3.6) for all asbestos-related workers, while others have reported an SMR of 1.24 (95% CI: 0.76-2.5) for those working in chrysotile mines and mills.

IARC The IARC, also known as the International Agency for Research on Cancer has classified all forms of asbestos carcinogenic. All types of asbestos claim can cause mesothelioma and other health issues, however the risk is dependent on the amount of exposure that individuals are exposed to, the type of asbestos involved as well as the length of their exposure and the way in the way it is inhaled or ingested. IARC has declared that the best choice for people is to avoid all types of asbestos. However, if someone has been exposed to asbestos in the past and suffer from a disease such as mesothelioma and other respiratory illnesses it is recommended that they seek advice from their doctor or NHS 111.

Amphibole

Amphibole is one of the minerals that form long prism or needle-like crystals. They are a kind of inosilicate mineral composed of double chains of SiO4 molecules. They have 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, which are connected in rings of six. Tetrahedrons are distinguished from each other with octahedral strips.

Amphibole minerals are found in metamorphic and igneous rocks. They are typically dark-colored and tough. They are sometimes difficult to distinguish from pyroxenes because they have similar hardness and color. They also share a corresponding pattern of cleavage. However their chemistry allows many different compositions. The chemical compositions and crystal structure of the various mineral groups found in amphibole may be used to identify them.

The five asbestos types that belong to the amphibole group include amosite, anthophyllite as well as crocidolite and actinolite. While the most commonly used asbestos type is chrysotile. Each variety is unique in its own way. The most dangerous form of asbestos, crocidolite, is made up of sharp fibers that are easy to breathe into the lungs. Anthophyllite is a brownish to yellowish hue and is made mostly of iron and magnesium. This kind of stone was used to create cement and insulation materials.

Amphiboles can be difficult to study because of their complex chemical structure and the numerous substitutions. An in-depth analysis of the composition of amphibole minerals requires specialized techniques. EDS, WDS and XRD are the most commonly used methods for identifying amphiboles. However, these methods can only provide approximate identifications. These techniques, for instance cannot differentiate between magnesio-hornblende and hastingsite. Moreover, these techniques do not distinguish between ferro-hornblende as well as pargasite.
