The Dangers of Exposure to Asbestos

Before it was banned wooster asbestos was used in a myriad of commercial products. According to studies, exposure to asbestos can cause cancer and many other health problems.

You cannot tell if something includes asbestos by looking at it and you won't be able to taste or smell it. It is only visible when asbestos-containing materials are drilled, chipped or broken.

Chrysotile

At its height, chrysotile provided for 99percent of the asbestos produced. It was employed in many industries such as construction insulation, fireproofing, and construction. If workers were exposed to this toxic material, they could contract mesothelioma or other asbestos related diseases. Since the 1960s, when mesothelioma was first becoming a major concern, the use of asbestos has decreased significantly. It is still present in many products we use in the present.

Chrysotile can be safely used in the event that a thorough safety and handling plan is in place. It has been determined that, at today's controlled exposure levels, there is no undue risk to the workers handling the substance. Inhaling airborne fibers is strongly linked to lung cancer and lung fibrosis. This has been confirmed for both the intensity (dose) and time of exposure.

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

Chrysotile fibres are typically shorter than other forms of asbestos. They can enter the lungs and then enter the bloodstream. This makes them much more likely to cause ill-health effects than fibres with longer lengths.

When chrysotile is mixed with cement, it's extremely difficult for the fibres to breathe and pose any health risks. Fibre cement products have been extensively used throughout the world particularly in structures such as schools and hospitals.

Research has revealed that amphibole asbestos like amosite, crocidolite, or crocidolite, is less likely than chrysotile in causing diseases. These amphibole types have been the primary source of mesothelioma, as well as other asbestos-related illnesses. When the cement and chrysotile are combined, a durable, flexible product is created that is able to withstand extreme environmental hazards and weather conditions. It is also easy to clean after use. Asbestos fibers can be easily removed by a professional and safely eliminated.

Amosite

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

Asbestos minerals are made up of thin, long fibres that vary in length, ranging from very fine to wide and straight to curled. These fibres can be 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 talcum powder and vermiculite which are widely used in consumer products, such as baby powder cosmetics, face powder, and baby 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 to asbestos fibres were in the air, however certain workers were also exposed to asbestos-bearing rocks and contaminated vermiculite. Exposures varied according to the type of industry, the time period and geographic location.

The exposure to asbestos in the workplace is mostly due to inhalation. However there have been instances of workers being exposed via skin contact or by eating food items contaminated with asbestos. Asbestos is now only found in the environment from natural weathering of mined ores and the deterioration of products contaminated with sturgis asbestos attorney like insulation, car brakes, clutches as well as ceiling and floor tiles.

There is growing evidence that non-commercial amphibole fibres may also be carcinogenic. These fibres are not tightly knit like the fibrils found in amphibole or serpentine, but are instead loose elastic, flexible, and needle-like. These fibres can be found in mountains, sandstones and cliffs of a variety of countries.

Asbestos can enter the environment in a variety of ways, including through airborne particles. It is also able to leach into soil or water. This is caused by both natural (weathering of asbestos-bearing rock) as well as anthropogenic sources (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination of surface and ground water is largely associated with natural weathering, but it has also been caused by human activities such as milling and mining demolition and dispersal asbestos-containing materials, and the removal of contaminated soils for disposal in landfills (ATSDR, 2001). Exposure to asbestos-containing airborne fibres is still the primary cause of illness in people exposed to asbestos in the workplace.

Crocidolite

Inhalation exposure is the most commonly used method of exposure to asbestos fibres. These fibres can infiltrate the lung which can cause serious health issues. Mesothelioma as well as asbestosis and other diseases are caused by asbestos fibres. Exposure to asbestos fibers can occur in different ways, including contact with contaminated clothes or building materials. This kind of exposure is more hazardous when crocidolite (the blue form of asbestos) is involved. Crocidolite is a smaller, more fragile fibers, which are easier to breathe in and may lodge deeper in lung tissue. It has been associated with a higher number of mesothelioma-related cases than any other form of asbestos.

The six major types of asbestos are chrysotile amosite, epoxiemite, tremolite, anthophyllite, and actinolite. The most well-known asbestos types are epoxiemite and chrysotile, which together comprise the majority of commercial asbestos used. The other four asbestos types aren't as common, but may still be found in older structures. They are not as dangerous as chrysotile or amosite but can still be a risk when mixed with other minerals, or when mined near other naturally occurring mineral deposits, such as talc and vermiculite.

Numerous studies have revealed an association between stomach cancer and asbestos exposure. The evidence is contradictory. Certain researchers have cited an 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 percent confidence interval: 0.76-2.5), for those working in chrysotile mills and mines.

The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma, however, the risk is dependent on the amount of exposure, what kind of asbestos is involved, and the length of time that exposure lasts. IARC has stated that the best choice for people is to stay clear of all types of asbestos. If you have been exposed in the past to asbestos and are suffering from respiratory issues or mesothelioma, you should talk to your doctor or NHS111.

Amphibole

Amphiboles comprise a variety of minerals that create prism-like or needle-like crystals. They are an inosilicate minerals made of double chains of SiO4 molecules. They typically possess a monoclinic crystal system however some may 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 joined in rings of six. The tetrahedrons are separated by strips of octahedral sites.

Amphibole minerals are found in igneous and metamorphic rocks. They are typically dark-colored and are hard. They can be difficult to distinguish from pyroxenes due to their similar hardness and colors. They also have a comparable cleavage. Their chemistry permits a wide variety of compositions. The chemical compositions and crystal structure of the various minerals in amphibole can be used to determine their composition.

The five types of asbestos that belong to the amphibole group include amosite, anthophyllite and crocidolite. They also include actinolite. While the most commonly used asbestos type is chrysotile; each has distinct characteristics. Crocidolite is among the most dangerous asbestos kind. It contains sharp fibers that can be easily breathed into the lungs. Anthophyllite can be found in a brownish or yellowish hue and is made mostly of iron and magnesium. This variety was used to make cement and insulation materials.

Amphiboles are a challenge to analyze because of their complex chemical structure and numerous substitutions. Therefore, a detailed analysis of their composition requires specialized methods. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. These methods are only able to provide approximate identifications. These techniques, for example, cannot distinguish between magnesio hornblende and hastingsite. Additionally, these techniques do not distinguish between ferro-hornblende and pargasite.
