The Dangers of Exposure to Asbestos

Asbestos was used in thousands of commercial products prior to when it was banned. Studies have shown that exposure to asbestos can cause cancer as well as other health issues.

It is difficult to tell by taking a look at something if it’s made of asbestos. It is also impossible to taste or smell it. It is only visible when asbestos-containing materials are chipped, drilled or broken.

Chrysotile

At its height, chrysotile comprised up 99% of Asbestos Attorney production. It was employed in a variety of industries including construction insulation, fireproofing, and insulation. Unfortunately, if workers were exposed for long periods to this toxic material, they may develop mesothelioma, as well as other asbestos-related diseases. Fortunately, the use of this dangerous mineral has decreased dramatically since mesothelioma awareness began to increase in the 1960’s. However, trace amounts of it remain in common products that we use today.

Chrysotile can be used safely if a thorough safety and handling plan is in place. Personnel handling chrysotile aren’t exposed to an unreasonable amount of risk at the current safe exposure levels. Lung cancer, lung fibrosis and mesothelioma were 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 among a factory that primarily used chlorosotile to make friction materials and the national death rate. It was discovered that, over the course of 40 years, processing chrysotile asbestos at low levels of exposure There was no significant increase in mortality in this particular factory.

Unlike some other forms of asbestos, chrysotile fibres tend to be shorter. They can pass through the lungs, and even enter the bloodstream. They are therefore more likely to cause health issues than fibres that are longer.

When chrysotile is mixed into cement, it’s very difficult for the fibres to breathe and pose any health risk. Fibre cement products are extensively used all over the world particularly in structures like hospitals and schools.

Research has proven that chrysotile has a lower chance to cause disease than amphibole asbestos like amosite and crocidolite. Amphibole types like these are the main cause of mesothelioma, and other asbestos-related diseases. When chrysotile gets mixed with cement, it creates an extremely durable and flexible building product that can withstand extreme conditions in the weather and other environmental dangers. It is also easy to clean after use. Professionals can safely dispose of asbestos fibres after they have been removed.

Amosite

Asbestos is a term used to describe a class of silicate mineral fibrous that occur naturally in certain kinds of rock formations. It consists of six general groups: serpentine, amphibole, tremolite, anthophyllite and crocidolite (IARC, 1973).

Asbestos minerals are made up of long, Asbestos Attorney thin fibers that vary in length from fine to wide. They can be curled or straight. They are found in nature in bundles, or as individual fibrils. Asbestos minerals are also found in powder form (talc) or mixed with other minerals and sold as vermiculite and talcum powder that are widely used in consumer products like baby powder cosmetics, face powder and other.

The largest use of asbestos occurred in the early two-thirds of the 20th century in the period when it was employed in shipbuilding, insulation, fireproofing, and other construction materials. The majority of asbestos exposures for work were in the air, however some workers were also exposed to asbestos-bearing rocks and vermiculite that was contaminated. Exposures varied from industry to industry, era to and also from geographical location.

Asbestos exposure in the workplace is mainly caused by inhalation. However there have been instances of workers being exposed through contact with skin or through eating foods contaminated with asbestos settlement. asbestos compensation is found in the environment due to natural weathering and degradation of contaminated products like ceiling and floor tiles automobile brakes and clutches, as well as insulation.

It is becoming increasingly apparent that non-commercial amphibole fibers can also be carcinogenic. These are fibres that are not the tightly weaved fibrils of amphibole or serpentine minerals but instead are flexible, loose and needle-like. These fibres can be found in cliffs, mountains and sandstones in a variety of countries.

Asbestos enters the environment mainly as airborne particles, Asbestos Attorney but it also leaches into water and soil. This is caused by both natural (weathering of asbestos-bearing rock) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground water is mostly due to natural weathering, but has also been caused by human activities such as mining and milling, demolition and dispersal of asbestos-containing material and the disposal of contaminated dumping soils in landfills (ATSDR 2001). Exposure to asbestos-containing airborne fibers is the primary cause of illness in people exposed to it occupationally.

Crocidolite

Inhalation exposure is the most commonly used method of exposure to asbestos fibres. These fibres can get into the lung and cause serious health problems. Mesothelioma, asbestosis, and other illnesses are caused by asbestos fibres. Exposure to asbestos fibers can be experienced in other ways, including contact with contaminated clothes or building materials. The risks of exposure are higher when crocidolite, the asbestos’ blue form, is involved. Crocidolite fibers are less dense and more fragile making them more palatable to breathe in. They can also be lodged deeper in lung tissue. It has been linked to a greater number of mesothelioma cases than any other form of asbestos.

The six major types are chrysotile as well as amosite. The most common forms of asbestos are chrysotile and epoxiemite, which together make up 95% all commercial asbestos used. The other four asbestos types aren’t as prevalent, but could still be found in older structures. They are not as hazardous as amosite and chrysotile, however they could be a risk when combined with other asbestos minerals or when mined in close proximity to other naturally occurring mineral deposits, like vermiculite or talc.

Many studies have discovered an association between exposure to asbestos and stomach cancer. Several studies have found a link between asbestos exposure and stomach. The evidence isn’t unanimous. Some researchers have cited a SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, while others have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for workers in mines and chrysotile mills.

IARC the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All types of asbestos can cause mesothelioma or other health issues, but the risks vary according to the amount of exposure individuals are exposed to, the kind of asbestos used as well as the length of their exposure and the method by the way it is inhaled or consumed. IARC has stated that the best choice for people is to avoid all forms of asbestos. If you’ve been exposed in the past to asbestos and suffer from a respiratory disorder or mesothelioma then you should consult your GP or NHS111.

Amphibole

Amphiboles are a grouping of minerals that can form prism-like or needle-like crystals. They are a type of inosilicate mineral made up of double chains of SiO4 molecules. They have a monoclinic structure of crystals, however certain crystals have an orthorhombic form. 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. The tetrahedrons can be separated by strips of octahedral site.

Amphiboles are found in metamorphic and igneous rock. They are usually dark-colored and are hard. Due to their similarity in hardness and color, they may be difficult for some to distinguish from pyroxenes. They also share a similar pattern of cleavage. However their chemistry permits many different compositions. The chemical compositions and crystal structures of the various mineral groups in amphibole could be used to determine their composition.

The five asbestos types in the amphibole class include amosite, anthophyllite, crocidolite, and actinolite. While the most commonly used asbestos type is chrysotile each type has its own unique characteristics. Crocidolite is considered to be the most hazardous asbestos kind. It is composed of sharp fibers that can be easily inhaled into the lungs. Anthophyllite is brown to yellowish in color and is made up of magnesium and iron. This type was used to make cement and insulation materials.

Amphiboles are difficult to analyze due to their complex chemical structure and the numerous substitutions. A detailed analysis of the composition of amphibole minerals requires special techniques. The most commonly used methods to identify amphiboles are EDS, WDS, and XRD. These methods are only able to provide approximate identifications. For instance, these techniques are unable to distinguish between magnesio-hastingsite from magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro-hornblende and pargasite.
