The Dangers of Exposure to Asbestos

Asbestos was used in thousands of commercial products before it was banned. Research suggests that exposure to asbestos can cause cancer and other health issues.

You can't tell if something is munford asbestos lawsuit-containing simply by looking at it and you won't be able to smell or taste it. It is only found when the asbestos-containing materials are drilled, chipped or broken.

Chrysotile

At the height of its use, chrysotile made up 99% of the asbestos production. It was used in many industries like construction insulation, fireproofing, and insulation. If workers were exposed to this toxic substance, they could develop mesothelioma or other asbestos related diseases. Since the 1960s, when mesothelioma first became a problem, the use of asbestos has been reduced significantly. However, trace amounts of it can still be found in many of the products we use in the present.

Chrysotile can be safely used if a thorough safety and handling plan is in place. Workers handling chrysotile are not at risk of being exposed to a high degree of risk at the present controlled exposure levels. Lung cancer, lung fibrosis and mesothelioma were all linked to breathing airborne respirable fibres. This has been proven for both intensity (dose) and time of exposure.

In one study, mortality rates were compared between a factory that used a large proportion of chlorosotile to make friction materials and national death rates. The study found that, after 40 years of processing at low levels of chrysotile there was no significant rise in mortality rates at this facility.

Chrysotile fibres are usually shorter than other forms of asbestos. They are able to penetrate the lungs and pass into the bloodstream. This makes them more prone to causing health effects than fibres with longer lengths.

When chrysotile gets mixed with cement, it's extremely difficult for the fibres to breathe and pose any health risks. The fibre cement products are extensively used across the globe particularly in buildings like hospitals and schools.

Research has revealed that chrysotile is less likely to cause illness than amphibole asbestos such as amosite and crocidolite. These amphibole types have been the most common cause of mesothelioma and other asbestos-related illnesses. When the cement and chrysotile are combined together, a strong, flexible product is created that is able to stand up to extreme environmental hazards and weather conditions. It is also easy to clean after use. Professionals can safely eliminate asbestos fibres when they have been removed.

Amosite

Asbestos is a grouping 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 consist of thin, long fibers that vary in length from very fine to broad and straight to curled. They can be found in nature in bundles or as individual fibrils. Asbestos can also be found in a powder form (talc), or mixed with other minerals to make talcum powder or vermiculite. They are extensively used as consumer goods, like baby powder, cosmetics, and face powder.

The greatest use of asbestos occurred in the first two-thirds of twentieth century in the period when it was employed in insulation, shipbuilding, fireproofing and other construction materials. Most occupational exposures were asbestos fibres in the air, however some workers were exposed to contaminated vermiculite or talc, and to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied according to the industry, time frame, and geographic location.

The majority of occupational exposures to asbestos were due to inhalation. However, certain workers were exposed through skin contact or through eating contaminated food. Asbestos is only present in the environment from natural weathering of mined ores and the degrading of contaminated materials like insulation, car brakes, clutches, as well as floor and ceiling tiles.

There is evidence to suggest that non-commercial amphibole fibres may also be carcinogenic. They are not tightly weaved like the fibrils that are found in amphibole and serpentine but are instead loose elastic, flexible, and needle-like. They can be found in the mountain sandstones, cliffs and sandstones from a variety of nations.

Asbestos is able to enter the environment in a variety ways, including as airborne particles. It is also able to leach into water or soil. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and disposal of asbestos-containing materials in landfill sites) sources. Asbestos contamination of surface and ground waters is primarily due to 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 dumping material in landfills (ATSDR 2001). The inhalation of asbestos fibres is still the primary reason for illness among those exposed to asbestos at work.

Crocidolite

Inhalation exposure to asbestos is the most common way people are exposed harmful fibres, which could then get into the lungs and cause serious health issues. Mesothelioma, asbestosis, and other illnesses are caused by asbestos fibres. Exposure to fibers can occur in a variety of ways like contact with contaminated clothing or materials. This kind of exposure is more hazardous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are smaller and more fragile making them more palatable to inhale. They can also get deeper within lung tissues. It has been linked to a higher number of mesothelioma related cases than any other form of asbestos.

The six major types are chrysotile as well as amosite. Amosite and chrysotile are the most commonly used types of asbestos. They comprise 95% of all commercial chester asbestos lawsuit that is used. The other four forms haven't been as widely used but they can be found in older buildings. They are not as dangerous as chrysotile or amosite but can still pose a threat when mixed with other minerals, or when mined near other naturally occurring mineral deposits such as talc and vermiculite.

Several studies have found an connection between exposure to asbestos and stomach cancer. Numerous studies have shown a link between asbestos exposure and stomach. The evidence is not conclusive. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95 percent CI: 0.7-3.6) for all asbestos-related workers and munford asbestos Lawsuit others have reported an SMR of 1.24 (95% C.I. 0.76-2.5) for those who work in chrysotile mines and mills.

The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All types of asbestos can cause mesothelioma and other health issues, but the risks are different based on the amount of exposure that individuals are exposed to, the type of cleveland asbestos attorney involved as well as the length of their exposure and the way in the way that it is breathed in or consumed. IARC has declared that the best choice for people is to stay clear of all forms of asbestos. If someone has been exposed to asbestos in the past and suffer from a disease such as mesothelioma or other respiratory conditions it is recommended that they seek advice from their physician or NHS 111.

Amphibole

Amphiboles are groups of minerals which can create prism-like or needle-like crystals. They are an inosilicate mineral made up of double chains of SiO4 molecules. They usually possess a monoclinic crystal system however, 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 linked in rings of six. The tetrahedrons are separated one another with octahedral strips.

Amphiboles are present in metamorphic and igneous rock. They are typically dark and hard. They are sometimes difficult to differentiate from pyroxenes due to their similar hardness and color. They also share a similar cut. Their chemistry can allow for a range of compositions. The chemical compositions and crystal structure of the different minerals in amphibole can be used to determine their composition.

The five types of asbestos belonging to the amphibole family are amosite, anthophyllite as well as crocidolite and actinolite. While the most frequently used asbestos type is chrysotile each type has its own distinct characteristics. Crocidolite is considered to be the most hazardous asbestos kind. It contains sharp fibers that are easily breathed into the lungs. Anthophyllite ranges from brown to yellowish in color and is composed of magnesium and iron. This type of stone was once used in products like cement and insulation materials.

Amphibole minerals can be difficult to analyze because they have complex chemical structures and many substitutions. Therefore, a thorough analysis of their composition requires special methods. EDS, WDS and XRD are the most widely used methods of identifying amphiboles. However, these methods can only give approximate identifications. For instance, these methods cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques also don't distinguish between ferro-hornblende as well as pargasite.
