The Dangers of Exposure to Asbestos

Before it was banned, asbestos was used in thousands commercial products. Research shows that exposure to asbestos can cause cancer and other health problems.

You cannot tell by just looking at something if it's made of asbestos. Also, you cannot smell or taste it. It is only visible when materials containing asbestos attorney (visit the following web page) are drilled, chipped or broken.

Chrysotile

At its height, chrysotile provided for 99percent of the asbestos that was produced. It was employed in many industries such as construction insulation, fireproofing, and construction. If workers are exposed to asbestos, they are likely to develop mesothelioma or other asbestos-related diseases. Since the 1960s, when mesothelioma was first becoming a problem, the use of asbestos has been drastically reduced. However, trace amounts remain in the products we use today.

Chrysotile is safe to use in the event that a thorough safety and handling plan is put into place. People who handle chrysotile do not exposed to a significant amount of risk at current safe exposure levels. The inhalation of airborne fibres has been found to be strongly linked with lung fibrosis and lung cancer. This has been proven in terms of intensity (dose) as well as the duration of exposure.

A study that looked at an industrial facility that used almost exclusively chrysotile for manufacturing friction materials compared mortality rates in this facility with national death rates. The study concluded that, after 40 years of manufacturing low levels of chrysotile, there was no significant rise in mortality rates at this facility.

In contrast to other forms of asbestos, chrysotile fibres tend to be smaller. They can enter the lungs and enter the bloodstream. They are more likely to cause health problems over longer fibres.

When chrysotile is mixed into cement, it's extremely difficult for the fibres to air-borne and cause health hazards. Fibre cement products are extensively utilized in many areas of the world, including schools and hospitals.

Studies have shown that chrysotile is less prone to cause disease than amphibole asbestos such as crocidolite and amosite. These amphibole types are the primary cause of mesothelioma, and other asbestos-related diseases. When chrysotile mixes with cement, it forms an extremely durable and flexible building product that can withstand harsh weather conditions and other environmental hazards. It is also simple to clean after use. Asbestos fibers can be easily removed by a professional and eliminated.

Amosite

Asbestos is a category of fibrous silicates found in a variety of rock formations. It is comprised of six general groups: amphibole, serpentine as well as tremolite, anthophyllite, 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 can be found in nature in bundles or individual fibrils. Asbestos is also found in a powder form (talc), or mixed with other minerals to create vermiculite or talcum powder. These are widely used as consumer goods, such as baby powder cosmetics and facial powder.

The greatest asbestos litigation use was during the early two-thirds of the twentieth century, when it was used in insulation, shipbuilding, fireproofing, and other construction materials. The majority of occupational exposures were asbestos fibres that were borne in the air, but some workers were exposed vermiculite or talc that was contaminated and also to fragments of asbestos-bearing rock (ATSDR 2001). Exposures varied by industry, time and geographic location.

Most asbestos exposures that workers were exposed to was due to inhalation, but certain workers were exposed through skin contact or through eating contaminated food. Asbestos can be found in the air due to the natural weathering of mined ore and the deterioration of products contaminated with asbestos such as insulation, car brakes, clutches and ceiling and floor tiles.

It is becoming increasingly apparent that amphibole fibers that are not commercially available could also be carcinogenic. These are the fibres that do not have the tight weaved fibrils of amphibole and serpentine minerals, but instead are loose, flexible and needle-like. These fibers can be found in mountains, sandstones, and cliffs of a variety of countries.

Asbestos gets into the environment primarily as airborne particles, but it also leaches into water and soil. This can be triggered by both natural (weathering of asbestos-bearing rocks) and anthropogenic causes (disintegration of asbestos-containing wastes as well as disposal in landfill sites). Asbestos contamination in surface and ground waters is primarily caused through natural weathering. However it can also be caused by human activity, for instance through milling and mining of asbestos legal-containing materials, demolition and dispersal, and the disposal of contaminated dumping material in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the primary reason for illness among those exposed to asbestos in their occupation.

Crocidolite

Inhalation exposure to asbestos is the most frequent way people are exposed to harmful fibres that can then enter the lungs and cause serious health issues. Mesothelioma, asbestosis, and other illnesses can be caused by asbestos fibres. The exposure to asbestos fibres could also take place in other ways, such as contact with contaminated clothing or building materials. The dangers of this kind of exposure are higher when crocidolite (the asbestos in the blue form, is involved. Crocidolite is smaller and more fragile fibers that are easier to breathe in and can get deeper in lung tissue. It has been associated with a higher number of mesothelioma cases than any other form of asbestos.

The six main types of asbestos are chrysotile, amosite, epoxiemite, tremolite anthophyllite and actinolite. Amosite and chrysotile are the most commonly used forms of asbestos and make up 95% of all commercial asbestos in use. The other four asbestos types are not as common, but may still be present in older structures. They are less hazardous than amosite and chrysotile, but they may pose a danger when combined with other asbestos minerals, or when mined close to other mineral deposits, like vermiculite or talc.

Numerous studies have proven that there is a link between stomach cancer and asbestos exposure. However the evidence isn't conclusive. Certain researchers have reported an SMR (standardized mortality ratio) of 1.5 (95 percent 95% confidence interval: 0.7-3.6) for all workers exposed to asbestos, while others have reported an SMR of 1.24 (95 percent 95% CI: 0.76-2.5) for those who work in chrysotile mines and mills.

IARC, the International Agency for Research on Cancer has classified all types of asbestos carcinogenic. All asbestos types can cause mesothelioma, but the risks vary depending on how much exposure, the type of asbestos is involved and the length of time that exposure lasts. The IARC has advised that abstaining from all asbestos forms is the best option as it is the most secure option for those who are exposed. If you have been exposed to asbestos and are suffering from a respiratory condition or mesothelioma, then you should seek advice from your physician or NHS111.

Amphibole

Amphibole is one of the minerals that form long prisms or needle-like crystals. They are a type of inosilicate mineral composed 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 are composed of (Si,Al)O4 tetrahedrons that are linked in rings of six. Tetrahedrons can be separated by octahedral strips.

Amphibole minerals can be found in metamorphic and igneous rocks. They are usually dark and hard. Due to their similarity of hardness and color, they may be difficult for some people to distinguish from the pyroxenes. They also share a corresponding design of cleavage. However their chemistry allows many different compositions. The various mineral groups in amphibole can be identified by their chemical compositions and crystal structures.

Amphibole asbestos comprises chrysotile and the five types of asbestos amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. Each type of asbestos has its own distinctive properties. The most harmful type of asbestos, crocidolite is composed of sharp fibers that are easy to breathe into the lung. Anthophyllite can be found in a brownish or yellowish hue and is made mostly of iron and magnesium. This kind of material was used to create cement and insulation materials.

Amphibole minerals are difficult to analyze due to their complex chemical structures and a variety of substitutions. Therefore, a thorough analysis of their composition requires special techniques. The most common methods for identifying amphiboles is EDS, WDS, and XRD. These methods are only able to provide approximate identifications. For instance, these methods cannot differentiate between magnesio-hastingsite and magnesio-hornblende. In addition, these techniques can not distinguish between ferro-hornblende and pargasite.
