The Dangers of Exposure to Asbestos

Asbestos was found in thousands of commercial products prior to when it was banned. According to research, exposure to asbestos can cause cancer, as well as other health problems.

It is impossible to tell just by looking at something whether it is made up of asbestos. Also, salida asbestos attorney you cannot taste or smell it. It is only visible in the event that asbestos-containing products are drilled, chipped or broken.

Chrysotile

At its peak, chrysotile accounted for 99% of the asbestos made. It was employed in many industries which included construction insulation, fireproofing, and construction. Unfortunately, if workers were exposed to the toxic substance, they could develop mesothelioma or other asbestos related diseases. Fortunately, the use of this toxic mineral has decreased significantly since mesothelioma awareness began to increase in the 1960's. However, trace amounts are still present in products that we use today.

Chrysotile is safe to use if you have a comprehensive safety and handling program in place. Chrysotile handling workers aren't at risk of being exposed to a high degree of risk at the current safe exposure levels. Lung fibrosis, lung cancer and mesothelioma have been strongly associated with breathing in airborne respirable fibres. This has been proven both for the intensity (dose) as well as the duration of exposure.

A study that looked at the operation of a factory that utilized almost exclusively chrysotile for manufacturing friction materials compared the mortality rates of this factory with national mortality rates. The study concluded that, after 40 years of processing at low levels of chrysotile there was no significant increase in mortality at this factory.

Chrysotile fibers are generally shorter than other types of asbestos. They can enter the lungs, and enter the bloodstream. They are more likely to cause health problems over longer fibres.

It is extremely difficult for chrysotile fibres to be inhaled or to pose a health risk when mixed with cement. Fibre cement products have been extensively used all over the world particularly in buildings like hospitals and schools.

Research has shown that amphibole asbestos such as amosite or crocidolite is less likely than chrysotile to cause disease. These amphibole types are the main cause of mesothelioma and other asbestos-related diseases. When chrysotile and cement are mixed together, a strong, flexible product is created which is able to withstand the most extreme weather conditions and environmental hazards. It is also easy to clean after use. Asbestos fibers can be easily removed by a professional, and then removed.

Amosite

Asbestos is a category of silicate mineral fibrous which are found naturally in a variety of kinds of rock formations. It is comprised of six main groups: serpentine, amphibole anthophyllite, tremolite and crocidolite (IARC, 1973).

Asbestos minerals are composed of thin, long fibers that vary in length from very fine to broad and straight to curled. They are present in nature as individual fibrils or as bundles with splaying ends referred to as fibril matrix. Asbestos is also found in powder form (talc) or mixed with other minerals to create vermiculite or talcum powder. They are extensively used in consumer products such as baby powder, cosmetics, and even face powder.

Asbestos was widely used during the first two thirds of the 20th century for shipbuilding insulation, fireproofing and various other construction materials. The majority of occupational exposures were airborne asbestos fibres, but certain workers were exposed to vermiculite and talc that had been contaminated and also to fragments of asbestos-bearing rocks (ATSDR, 2001). Exposures varied according to the industry, time frame, and geographic location.

The majority of asbestos exposures that workers were exposed to was due to inhalation, but some workers were also exposed through skin contact or by eating food contaminated with asbestos. Asbestos is only found in the environment due to natural weathering and degradation of contaminated products, such as ceiling and floor tiles, car brakes and clutches as well as insulation.

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

Asbestos can enter the environment in many ways, including as airborne particles. It can also be absorbed into soil or water. This can be 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 in ground and surface waters is primarily caused through natural weathering. However, it has also been caused anthropogenically, such as by the milling and mining of asbestos-containing materials demolition and dispersal and the disposal of contaminated dumping materials in landfills (ATSDR 2001). Inhalation exposure to airborne asbestos fibres is still the primary cause of illness in people who are exposed to asbestos on a daily basis.

Crocidolite

Inhalation exposure is the most common method of exposure to kuna asbestos lawsuit fibres. The fibres can penetrate the lungs which can cause serious health issues. Mesothelioma as well as asbestosis and other illnesses can be caused by asbestos fibres. Exposure to fibres can occur in a variety of ways like contact with contaminated clothing, or building materials. This kind of exposure is more hazardous when crocidolite (the blue form of asbestos) is involved. Crocidolite has smaller, more fragile fibers that are easier to breathe in and can get deeper in lung tissue. It has been linked to a larger number of mesothelioma related cases than any other type of tecumseh asbestos lawyer.

The six primary types are chrysotile, amosite and chrysotile. Amosite and chrysotile are the most commonly used types of asbestos, and comprise 95 percent of all asbestos used in commercial construction. The other four have not been as popularly used however, they could be present in older buildings. They are not as dangerous as amosite or chrysotile but still be dangerous when mixed with other minerals, or when mined close to other mineral deposits, such as vermiculite and talc.

Numerous studies have demonstrated the connection between stomach cancer and asbestos exposure. However the evidence isn't conclusive. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95 percent 95% confidence interval: 0.7-3.6) for all workers exposed to asbestos while other studies have reported an SMR of 1.24 (95% C.I. 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 wheat ridge asbestos carcinogenic. All asbestos types can cause mesothelioma however the risks differ based on the amount of exposure, what type of asbestos is involved, and how long the exposure lasts. The IARC has advised that avoid all forms of asbestos should be the top priority since this is the most safe option for those who are exposed. However, if a person has been exposed to asbestos in the past and are suffering from an illness such as mesothelioma, or other respiratory diseases and require advice, they should seek out guidance from their GP or NHS 111.

Amphibole

Amphibole is a group of minerals that form long prism or needlelike crystals. They are a type inosilicate mineral composed of double chains of molecules of SiO4. They have a monoclinic arrangement of crystals, however some exhibit an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains are composed of (Si,Al)O4 Tetrahedrons, which are connected in rings of six. The tetrahedrons can be separated by strips of octahedral site.

Amphibole minerals can be found in metamorphic and igneous rocks. They are typically dark-colored and are hard. They are sometimes difficult to distinguish from pyroxenes as they share similar hardness and color. They also share a similar Cleavage. Their chemistry can allow for a range of compositions. The various mineral groups in amphibole can be identified by their chemical compositions as well as crystal structures.

Amphibole asbestos includes chrysotile and the five types of asbestos: amosite anthophyllite (crocidolite), amosite (actinolite), and amosite. Each kind of asbestos has its own distinct properties. Crocidolite is the most dangerous asbestos kind. It contains sharp fibers which are easily breathed into the lung. Anthophyllite is a brownish to yellowish color and is made primarily of magnesium and iron. This variety was used to make cement and insulation materials.

Amphiboles are difficult to analyse due to their complicated chemical structure and the numerous substitutions. Therefore, a detailed analysis of their composition requires special methods. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. However, these methods only provide approximate identifications. For instance, these methods can't distinguish between magnesio hastingsite and magnesio-hornblende. Additionally, these techniques do not distinguish between ferro-hornblende and pargasite.
