The Dangers of Exposure to Asbestos

Asbestos was used in a variety of commercial products prior to when it was banned. According to research, Edgewater asbestos lawsuit asbestos exposure can cause cancer and a host of other health problems.

It is difficult to tell if something has asbestos just by looking at it and you are unable to taste or smell it. It is only found when the asbestos-containing materials are drilled, chipped or broken.

Chrysotile

At its peak, chrysotile accounted for 99percent of the asbestos produced. It was used in many industries including construction insulation, fireproofing, and insulation. If workers are exposed to asbestos, they may develop mesothelioma and other beaumont asbestos lawsuit-related diseases. Fortunately, the use of this toxic mineral has decreased drastically since mesothelioma awareness started to increase in the 1960's. However, it is still present in trace amounts. can still be found in many of the products we use today.

Chrysotile is safe to use in the event that you have a complete safety and handling program in place. Chrysotile handling workers aren't at risk of being exposed to a high degree of risk at current limits of exposure. Lung cancer, lung fibrosis and mesothelioma have all been found to be strongly linked to breathing in airborne respirable fibres. This has been proven for both the intensity (dose) and time span of exposure.

A study that looked at a facility that used nearly exclusively chrysotile for manufacturing friction materials compared the mortality rates of this factory with national mortality rates. It was found that, for 40 years of preparing chrysotile asbestos at low levels of exposure There was no significant extra mortality in the factory.

Contrary to other types of asbestos, chrysotile fibers tend to be shorter. They can penetrate the lungs and enter the bloodstream. This makes them much more prone to causing health effects than fibrils with a longer length.

When chrysotile is mixed into cement, it's extremely difficult for the fibres to air-borne and pose any health risk. Fibre cement products are used in a variety of locations around the world, including schools and hospitals.

Studies have shown that chrysotile is less prone to cause disease than amphibole asbestos such as amosite and crocidolite. These amphibole types have been the primary cause of mesothelioma as well as other asbestos-related illnesses. When chrysotile is mixed in with cement, it forms a tough, 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 eliminate asbestos fibres when they have been removed.

Amosite

Asbestos is one of the groups of fibrous silicates found in certain types rock formations. It is comprised of six general groups: serpentine, amphibole as well as tremolite, anthophyllite, and crocidolite (IARC, 1973).

Asbestos minerals are made up of long, thin fibers that range in length from fine to wide. They can also be straight or curled. These fibers are found in nature as individual fibrils or as bundles that have splaying ends, referred to as fibril matrix. Asbestos minerals can be found in the form of a powder (talc) or mixed with other minerals and sold as vermiculite and talcum powder and are used in consumer products, such as baby powder cosmetics, face powder, and baby powder.

The greatest use of asbestos occurred in the first two-thirds period of the 20th century in the period when it was employed in insulation, shipbuilding, fireproofing and other construction materials. Most occupational exposures were to airborne asbestos fibres, but some workers were exposed toxic talc or vermiculite and also to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied by industry, time period and geographical location.

The exposure to asbestos in the workplace is usually because of inhalation. However there have been instances of workers being exposed through skin contact or eating food that is contaminated. Asbestos can be found in the environment from the natural weathering of mined ore and deterioration of contaminated products like insulation, car brakes and clutches, and floor and ceiling tiles.

There is evidence emerging that amphibole fibers that are not commercially available could also be carcinogenic. These fibers aren't tightly knit like the fibrils found in amphibole and serpentine, they are loose, flexible, and needle-like. These fibers are found in cliffs, mountains and sandstones of many countries.

Asbestos gets into the environment primarily in the form of airborne particles, however it can also be absorbed into water and soil. This can be triggered by both natural (weathering of asbestos-bearing rocks) as well as anthropogenic sources (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination in surface and ground water is mostly caused by natural weathering. However it is also caused anthropogenically, such as through the mining and milling of asbestos-containing materials, demolition and dispersal, and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary cause of disease among those exposed to asbestos during their work.

Crocidolite

Inhalation exposure is the most popular method of exposure to asbestos fibres. The fibres can penetrate the lungs, causing serious health problems. These include mesothelioma and asbestosis. The exposure to asbestos can happen in other ways, too including contact with contaminated clothing or building materials. This kind of exposure is more hazardous when crocidolite (the blue asbestos form) is involved. Crocidolite is a smaller, more fragile fibers that are more easy to inhale and can lodge deeper in lung tissue. It has been associated with more mesothelioma cancer cases than other asbestos types.

The six major types are chrysotile and amosite. The most commonly used forms of asbestos are epoxiemite and chrysotile which together comprise 95% all commercial asbestos used. The other four forms haven't been as widely utilized, but they may still be found in older buildings. They are less harmful than amosite and chrysotile, however they may pose a danger when combined with other asbestos minerals or Loudon asbestos mined close to other mineral deposits, like talc or vermiculite.

Numerous studies have proven an association between stomach cancer and asbestos exposure. The evidence isn't conclusive. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95% confidence interval: 0.7-3.6), for all asbestos workers, whereas others report an SMR of 1,24 (95 percent confidence interval: 0.76-2.5), for workers in chrysotile mines or chrysotile mills.

IARC The IARC, also known as the International Agency for Research on Cancer has classified all kinds of asbestos as carcinogenic. All asbestos types can cause mesothelioma however, the risk is dependent on the amount of exposure, the type of asbestos is involved and how long the exposure lasts. The IARC has recommended that avoid all forms of asbestos is the most important thing to do since this is the most secure option for people. If you've been exposed to asbestos and suffer from a respiratory illness or mesothelioma condition, then you should consult your GP or NHS111.

Amphibole

Amphiboles are a collection of minerals that may create prism-like or needle-like crystals. They are a kind of inosilicate mineral that is composed of double chains of molecules of SiO4. They usually have a monoclinic crystal structure, although some have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains comprise (Si, Al)O4 tetrahedrons linked together in a series of six tetrahedrons. The tetrahedrons can be separated by strips of octahedral site.

Amphiboles can be found in metamorphic and igneous rock. They are usually dark-colored and tough. They are sometimes difficult to differentiate from pyroxenes because they have similar hardness and colors. They also share a corresponding cleavage. Their chemistry allows for a variety of compositions. The chemical compositions and crystal structure of the different mineral groups found in amphibole may be used to identify them.

The five asbestos types belonging to the amphibole family are amosite, anthophyllite and crocidolite. They also include actinolite. Each type of asbestos has its own distinctive properties. The most harmful type of Rockwall asbestos, crocidolite, is made up of sharp fibers that are simple to inhale into the lung. Anthophyllite ranges from brown to yellowish in color and is composed of magnesium and iron. This kind of material was used to create cement and insulation materials.

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