Types of Asbestos

All six types of amorphous asbestos are found in nature as bundles of fine and durable fibres. They are resistant to heat, fire, chemicals and electrical conductivity. They have a high tensile and wear strength. Asbestos is used in a variety of products, including floor tiles and insulation paint, as well as fabric that is heat-resistant.

Chrysotile

Before it was banned in 1980, Chrysotile (also known as white asbestos) was the most frequently used form of the mineral. It was used because it was fireproof, cheap and durable. However, it was found to be extremely dangerous and was linked to mesothelioma and other diseases. While some countries still make use of asbestos, a complete global ban is now needed.

Health care professionals are continuing to warn that all forms of asbestos, including chrysotile can cause cancer and no amount of exposure to asbestos case is safe. Companies who mine and sell asbestos claim that chrysotile is more safe than other forms of the mineral, because it's a tightly packed and non-friable.

This type of asbestos is less dangerous than the amphibole asbestos types, but it is still hazardous for workers to work with. Chrysotile is among the most commonly mined asbestos and is the one responsible for the majority of mesothelioma cases in the world. Chrysotile is a golden or brown yellow fibrous material that appears like threads, and feels soft to the touch. Under an electron microscope, the fibers appear more like tubes and are a combination of structural layers of the mineral that have been rolled in spiral form.

Chrysotile has been shown to be a cause of a variety of diseases which include pleural mesothelioma lung cancer and other respiratory issues. It has been linked to cardiovascular diseases and digestive issues. Those who work with chrysotile are particularly susceptible to developing these diseases because they are exposed to the mineral. Workers in construction and repair of vehicles are the most likely to come across Chrysotile asbestos as it was once extremely popular. It can be found in older houses and vehicles.

Amosite

Asbest is made from six different types of fibrous silicate minerals. Each mineral has a different chemical composition and properties. However they are all associated with a higher risk of mesothelioma. These include amphibole and serpentine minerals chrysotile and crocidolite (white asbestos), amosite, tremolite anthophyllite, tremolite, and anthophyllite.

Chrysotile is by far the most widely used type of asbestos case in the United States. Many homes and businesses still have it on their walls, roofs, and floors. It was also used as gaskets, thermal insulation and boiler seals in automobiles. Other common asbestos products that contain chrysotile are shingles as well as cement sheets and pipe insulation.

All forms of asbestos are dangerous when inhaled. The exposure to asbestos in any form can cause lung cancer, pleural diseases and mesothelioma. Exposure to asbestos is most often caused by breathing, but can also be caused by handling or working with asbestos fibres. Exposure to asbestos is particularly hazardous if the materials are brittle. This means they can crumble easily, and eventually, they can become dust particles in the air.

Friability is correlated with the fibrillar thickness and their length. Longer and thicker fibres are more likely to penetrate deeper into the lungs, while shorter and thinner fibres are less likely to do this.

Exposure to asbestos occurs most often when workers are handling or removing it. This is because asbestos is an extremely fine material that can be released into the air as dust after it is crushed or sanded. When asbestos is swept up or vacuumed, it can release small fibres in the air. This is because a sweeping action could cause the fibres to break apart, while vacuuming causes them to stick to other surfaces.

Crocidolite

In contrast to the serpentine asbestos (chrysotile), the amphibole asbestos has long straight chain-like fibres that are brittle and more dangerous when inhaled. Crocidolite (blue asbestos), amosite (brown asbestos) and Tremolite (red asbestos) are the most common amphibole asbestos, but it can also be found in other forms such as anthophyllite and actinolite. These asbestos types can be found in natural deposits with Chrysotile. Other asbestos minerals could be contaminants in crocidolite combined with chrysotile in the deposit.

Asbestos can be found in a variety of products, including asbestos cement pipe sheets, sheets, friction material used in coatings, brakes for cars, and gaskets. The fibres are made into paper, fabric, thread, mastics or bound with Portland cement, resins or plastics. The length and size of the fibres determine which is the most suitable application. The shorter fibres are typically used in electrical insulation, textiles and filters. The longer fibres are employed in asbestos cement sheets, pipes and flooring.

A number of studies have reported an association between exposure to asbestos and stomach cancer. These studies yield varied results however the conclusions are limited because of the absence of research. In general, the risk of stomach cancer appears to increase with increasing exposure to asbestos. However, the effect is diminished when consideration of latency prior to the first exposure is taken into account.

Other forms of asbestos have been implicated in the formation of mesothelioma an aggressive cancer that affects the chest and abdomen (Mesothelioma). Children who have been exposed to asbestos are more likely to develop mesothelioma. The reason isn't clear.

Lung cancer

Lung cancer is one the most frequent diseases caused by asbestos. It is caused by exposure to asbestos and is generally more severe than other forms of asbestos-related diseases. It affects the lungs and occasionally other organs, such as the stomach, heart, and bladder. It can also cause mesothelioma, a rare cancer that affects lung the lining.

Asbestos is one of naturally occurring fibrous silicate minerals. It is widely employed in construction and is present in a variety of products.

Most people are not affected by low levels of asbestos in the air. The people who do fall ill are often exposed to asbestos on a regular basis in a specific occupation and over a long period of time. The most intense exposures tend to be in jobs such as mining, shipbuilding construction, and insulation. In recent years, regulations from the government have reduced the use of and the presence of asbestos in construction sites. It is still found in older household products like crayons for children and toys.

All forms of asbestos can cause lung conditions such as asbestosis, mesothelioma, and other illnesses. Chrysotile is the most commonly recognized form of asbestos. Other types of asbestos lawyer are amphibole and crocidolite.

When asbestos-containing materials are disturbed, they release microscopic fibres that become airborne and can be inhaled. Inhaling these fibres, they can become trapped deep within the lungs. The asbestos fibres may cause scarring and inflammation of the lung. This can lead to mesothelioma, lung cancer, or other diseases that can take years to develop. Smoking cigarettes and having a family history of asbestos-related illnesses are other factors that increase your risk.

Mesothelioma

When asbestos is used to manufacture insulation or to construct and renovation of homes, tiny asbestos fibres are released into the air. The fibers can be inhaled or swallowed and can trigger serious health problems like mesothelioma.

The mesothelium is the lining that protects organs. Mesothelioma is typically found in the lung lining and abdomen. In some cases it may also manifest in the lining of the heart (pericardium mesothelioma) or testicles (tunica vaginalis mesothelioma).

Asbestos workers are more likely to develop mesothelioma due to exposure at work. However, the family members of asbestos workers are also at risk of developing mesothelioma. Mesothelioma may be difficult to recognize because symptoms aren't specific and often mimic those of more common diseases. Mesothelioma is often misdiagnosed and patients may not receive the treatment they need.

A mesothelioma diagnosis starts with an appointment with your doctor. The doctor will take an exhaustive medical history and inquire about any previous asbestos exposure. This will help them determine if your chance of developing the disease is higher.

Once the mesothelioma diagnosis is confirmed by your doctor, they will determine the type of mesothelioma is present. Pleural mesothelioma, the most common form of this disease, and accounts for around 88% of all mesothelioma cases each year. Other types include peritoneal and rare biphasic mesothelioma which contains epithelioid and sarcomatoid cancer cells. Your doctor will determine the best course of action for you depending on the type of mesothelioma. Treatment can increase your chances of surviving, depending on the type and the location of your mesothelioma.
