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 as well as other health issues.

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

Chrysotile

At the height of its use, chrysotile made the majority of posen asbestos lawyer production. It was employed in many industries such as construction insulation, fireproofing and insulation. If workers are exposed to asbestos, they may develop mesothelioma as well as other asbestos-related illnesses. Fortunately, the use of this harmful mineral has diminished dramatically since mesothelioma awareness began to increase in the 1960's. However, traces of it remain in the products we use today.

Chrysotile is safe to use provided you have a comprehensive safety and handling program in place. It has been discovered that, at today's controlled exposure levels, there is no undue risk to the workers handling it. Inhaling airborne fibers has been found to be strongly linked with lung cancer and lung fibrosis. This has been confirmed for both the intensity (dose) and the duration of exposure.

One study that studied an industrial facility that used almost exclusively chrysotile to manufacture friction materials, compared mortality rates in this factory with national mortality rates. It was discovered that, over the course of 40 years, processing asbestos chrysotile at low levels of exposure there was no signifi cant extra mortality in the factory.

Chrysotile fibres tend to be shorter than other types of asbestos. They can pass through the lungs and then enter the bloodstream. They are therefore more likely to cause health issues than fibres with longer lengths.

When chrysotile gets mixed with cement, it is very difficult for the fibres to become airborne and cause health hazards. The fibre cement products are extensively used all over the world particularly in structures like hospitals and schools.

Research has proven that chrysotile is less prone to cause illness than amphibole asbestos, such as amosite and crocidolite. These amphibole types are the primary cause of mesothelioma and other asbestos-related diseases. When chrysotile gets mixed with cement, it forms an extremely durable and flexible building product that can withstand the most extreme conditions in the weather and other environmental dangers. It is also easy to clean after use. Professionals can safely get rid of asbestos fibres after they have been removed.

Amosite

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

Asbestos minerals are made up of thin, long fibers that vary in length from extremely thin to broad and straight to curled. They are found in nature as individual fibrils or as bundles with splaying ends referred to as fibril matrix. Asbestos can also be found in powder form (talc) or combined with other minerals to create vermiculite or talcum powder. These are widely used as consumer goods, like baby powder, cosmetics and facial powder.

Asbestos was extensively used in the first two thirds of the 20th century to construct shipbuilding as well as insulation, fireproofing and various other construction materials. The majority of asbestos-containing exposures to the workplace occurred in the air, however some workers also were exposed to vicksburg asbestos law firm-bearing rocks and vermiculite that was contaminated. Exposures varied according to the industry, time frame and posen asbestos Lawyer geographical location.

Most asbestos exposures that workers were exposed to was because of inhalation, but certain workers were exposed through skin contact or through eating contaminated food. Asbestos can only be found in the natural environment due to natural weathering and degrading of contaminated materials, posen asbestos Lawyer such as ceiling and floor tiles, car brakes and clutches, and insulation.

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

Asbestos enters the environment mainly in the form of airborne particles, however it can also be absorbed into soil and water. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and anthropogenic (disintegration and disposal of asbestos-containing wastes in landfill sites) sources. Asbestos contamination of ground and surface water is mostly a result of natural weathering, however it has also been caused by anthropogenic activities like milling and mining, demolition and dispersal of asbestos-containing materials as well as the disposal of contaminated dumping soils in landfills (ATSDR 2001). Airborne oak harbor asbestos lawsuit fibres are the main cause of disease among those exposed to asbestos during their work.

Crocidolite

Inhalation exposure is the most common method of exposure to asbestos fibres. These fibres can infiltrate the lungs, causing serious health problems. Mesothelioma, asbestosis, and other diseases are caused by asbestos fibres. Exposure to asbestos fibres can occur in different ways, including contact with contaminated clothing or building materials. This kind of exposure is more dangerous when crocidolite (the blue form of asbestos) is involved. Crocidolite fibers are less dense and more fragile which makes them more difficult to breathe in. They can also get deeper in lung tissues. It has been associated with a higher number of mesothelioma-related cancers than any other form of asbestos.

The main types are chrysotile, amosite and chrysotile. The most well-known asbestos types are chrysotile and epoxiemite, which together make up the majority of commercial asbestos used. The other four have not been as widely utilized however they can be present in older buildings. They are less dangerous than amosite or chrysotile but still be a risk when combined with other minerals or when mined near other mineral deposits such as vermiculite and talc.

Numerous studies have revealed an association between stomach cancer and asbestos exposure. However, the evidence is contradictory. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95% range of CI: 0.7-3.6) for all asbestos-related workers and others have reported an SMR of 1.24 (95% of the CI = 0.76-2.5) for workers in chrysotile mines and mills.

IARC the International Agency for Research on Cancer, has classified all types of asbestos as carcinogenic. All asbestos types can cause mesothelioma, but the risks vary depending on how much exposure is taken, what type of asbestos is involved and how long the exposure lasts. The IARC has advised that abstaining from all asbestos forms should be the top priority because this is the safest option for individuals. If you've been exposed in the past to asbestos and are suffering from a respiratory condition or mesothelioma, you should consult your GP or NHS111.

Amphibole

Amphibole belongs to a group of minerals that form long prism or needle-like crystals. They are an inosilicate minerals made of double chains of SiO4 molecules. They usually have a monoclinic structure in their crystals however, 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 rings of six tetrahedrons. The tetrahedrons can be separated by strips of octahedral sites.

Amphibole minerals are found in metamorphic and igneous rocks. They are usually dark and hard. Because of their similar hardness and color, they may be difficult for some to distinguish from Pyroxenes. They also share a similar cleavage pattern. Their chemistry permits a wide range of compositions. The different amphibole mineral groups are identified by their chemical compositions and crystal structures.

The five types of asbestos in the amphibole family include amosite, anthophyllite and chrysotile and crocidolite. They also include actinolite. Each kind of asbestos has its own distinctive properties. Crocidolite is among the most dangerous asbestos type. It is made up of sharp fibers that can easily be breathed into the lung. Anthophyllite is yellowish to brown in color and is made up of iron and magnesium. This type was used to make cement and insulation materials.

Amphibole minerals can be difficult to study because of their complex chemical structures and a variety of substitutions. A thorough analysis of composition of amphibole minerals is a complex process that requires specialized techniques. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods only give approximate identifications. For instance, they cannot differentiate between magnesio-hastingsite and magnesio-hornblende. These techniques also don't distinguish between ferro-hornblende and.
