Types of Asbestos

All six kinds of asbestos naturally form bundles of pliable and thin fibres. They are resistant to chemical, heat, fire and electrical conductivity. They also have exceptional tensile strength and wear. Asbestos is a component in many products including floor tiles, insulation, paint, and fabric that is heat-resistant.

Chrysotile

Chrysotile, known as white asbestos, was the most common form of the mineral used in thousands of different products prior to its ban in the 1980s. It was popular because it was affordable, fireproof and durable. It was discovered to be extremely harmful and linked to mesothelioma and other cancers. While some countries still use asbestos, a worldwide ban is now required.

Health care professionals are continuing to warn that all types of asbestos, including chrysotile, are carcinogenic and any amount of exposure is safe. However, despite this, companies who mine and sell chrysotile say that the asbestos they make is more secure than older varieties of the mineral, because it is tightly packed and unfriable.

While this form of asbestos is less hazardous than amphibole asbestos, it is still a risk to handle. Chrysotile is among the most commonly mined asbestos and the one responsible for the majority of mesothelioma cases around the world. Chrysotile is a brown or golden yellow fibrous mineral that appears like threads, and feels soft to the touch. When examined with electron microscopy the fibres appear more like tubes. They are actually a mixture of structural layers of minerals that are rolled into a spiral shape.

Chrysotile is known to cause numerous diseases, including pleural mesothelioma and lung cancer. It has also been linked to digestive problems and cardiovascular disease. People who work with chrysotile are particularly at risk for developing these diseases since they are exposed to the mineral. People who work in construction and automobile repair are most likely to encounter Chrysotile asbestos as it was once very popular. It is often found in older buildings and vehicles.

Amosite

Asbest is made up of six different types of fibrous silicate minerals. Each mineral has its specific chemical composition and properties and all six are linked to an increased risk of mesothelioma. These include the amphibole and serpentine minerals chrysotile, the crocidolite (white asbestos) amosite (white asbestos), tremolite, anthophyllite, and tremolite.

Chrysotile asbestos is the most common asbestos type in the United States. It is still found today in the walls, roofs and floors of a variety of buildings and homes. It was also used as gaskets, thermal insulation, and boiler seals in automobiles. Other common asbestos products that contain chrysotile are shingles, cement sheets, and pipe insulation.

All forms of asbestos are dangerous when inhaled. The exposure to any form of asbestos can cause mesothelioma, lung cancer, and other pleural diseases. Inhalation is the most common route of exposure to asbestos, but it is also possible to be exposed by working with or handling fibres. Exposure is especially dangerous when the fibres are friable which means they break easily and are then able to airborne as dust particles.

Friability is a function of the length and thickness of the fibers. Fibers that are longer and thinner are more likely than shorter and shorter ones to penetrate into the lungs.

The most common way to expose workers to asbestos is by manipulating or removing it. Asbestos is an extremely fine, crystallized material that releases dust into the air when crushed or sanded. When asbestos is swept away or vacuumed, it could release tiny fibres in the air. This is because a sweeping motion can cause the fibres to break apart when vacuuming causes them to stick to other surfaces.

Crocidolite

Amphibole asbestos, unlike serpentine asbestos (chrysotile) is composed of long straight fibres that are brittle. They are also more dangerous to inhale. Crocidolite, amosite and tremolite are the most popular forms of amphibole. Other forms include anthophyllite or actinolite. These types of asbestos are commonly found in natural deposits alongside the chrysotile asbestos. It is believed that the other asbestos minerals are also contaminants in crocidolite deposits, and could be mixed with chrysotile asbestos present in the deposits.

Asbestos is used in a range of products including asbestos cement pipes and sheets and friction materials for automobile brakes, gaskets and coatings. The fibres can be weaved into paper, fabric, mastics, thread or tied with Portland cement resins or plastics. The length and size of the fibres will determine the most suitable application. The shorter fibres are typically used in textiles, electrical insulation and filters. The longer fibres are employed in asbestos cement sheets, pipes, and flooring.

Numerous studies have suggested a link between exposure to Asbestos lawyer and stomach cancer. The findings of these studies differ however the conclusions are influenced by the comparatively limited literature on this subject. In general, the risk of developing stomach cancer is likely to increase when the cumulative exposure to asbestos increases. The risk is lessened when the time from the initial exposure is taken into consideration.

Other types of asbestos are involved in the development mesothelioma (a malignant cancer that affects the lining of the abdomen and chest). It has been reported that children who are exposed to asbestos are at a higher risk of developing mesothelioma than adults. The reasons for this are not known.

Lung cancer

Lung cancer is one the most common cancers caused by asbestos. It is caused by exposure to asbestos over a long period of time and is more dangerous than any other asbestos-related disease. It can affect the lungs, and occasionally other organs such as the heart or stomach. It can also cause mesothelioma. an uncommon cancer that affects lung lining.

Asbestos is composed of six naturally occurring fibrous silicic minerals. It can be found in a number of different products and was once extensively used in construction, but has since been banned because of its negative effects.

Most people aren't affected by the low levels of asbestos in the air. Those who do become sick are usually exposed to asbestos regularly in a specific occupation and for a long period of time. The heaviest exposures tend to be in jobs such as mining, shipbuilding construction, and insulation. In recent years, regulations from the government have helped reduce the use of asbestos, and it is now used in fewer buildings. Some household products from the past like crayons, toys for children and even crayons, still contain asbestos.

All forms of asbestos can cause lung diseases such as mesothelioma and asbestosis among other diseases. Chrysotile asbestos is the most widely recognized kind of asbestos. Other types of asbestos are amphibole and crocidolite.

When asbestos-containing material is disturbed microscopic fibres release into the air and could be inhaled. The fibres can become trapped in the lungs after inhalation. Asbestos fibres can cause inflammation and scarring of the lung. This could result in lung carcinoma mesothelioma as well as other illnesses that can take years to develop. Other factors that increase the risk of developing an asbestos-related illness include smoking cigarettes and having an ancestral history of the condition.

Mesothelioma

When asbestos is used in the manufacture of insulation or in the construction of homes and buildings, it releases tiny asbestos fibers into the air. These fibers can be breathed in, or swallowed and cause serious health issues such as mesothelioma.

Mesothelioma is a form of cancer that occurs in the lining of organs, called the mesothelium. Mesothelioma typically affects the lung lining (pleural mesothelioma) and the abdomen (peritoneal mesothelioma). In certain cases it can also be found in the heart's lining (pericardium mesothelioma) or testicles (tunica vaginalis mesothelioma).

Asbestos workers are more likely to develop mesothelioma because of exposure at work. However, relatives of asbestos workers are also at risk of developing mesothelioma. It can be difficult to diagnose mesothelioma because the symptoms aren't distinct and frequently resemble those of other diseases. Mesothelioma could be misdiagnosed and victims may not get the treatment they need.

A visit to your doctor is the first step towards diagnosing mesothelioma. Your doctor will inquire about your medical background, including any asbestos exposure. This will help them determine if your risk of developing the disease is higher.

Your doctor will determine the type of mesothelioma that you have after a mesothelioma has been diagnosed. Pleural mesothelioma, the most prevalent type of the disease, accounts for about 80 percent of mesothelioma diagnoses every year. The other two types are peritoneal mesothelioma and a rare biphasic form of mesothelioma that contains both epithelioid and sarcomatoid cells. Your doctor will determine the best treatment option for you based on the type of mesothelioma. Treatment can increase your chances of surviving depending on the nature and location of mesothelioma.
