Chrysotile asbestos (also known as white asbestos) is an extremely dangerous naturally occurring mineral and a known carcinogen, meaning it causes cancer. No amount of chrysotile asbestos is safe for human exposure. Chrysotile is one of several asbestiform minerals, which are silicate minerals that occur in a fibrous habit, and asbestos exists in various commercial forms, including tremolite, that have been widely used in industry.
The more you understand about asbestos and the risk of encountering asbestos in your day-to-day environment, the better you can protect yourself from dangerous exposure and serious related diseases, such as mesothelioma. Chrysotile asbestos is the most common variety of asbestos found in consumer products. The National Institute for Occupational Safety and Health (NIOSH) and other health administration agencies play a critical role in researching asbestos hazards and regulating exposure to protect public health.
Asbestos is classified as a toxic substance and is regulated under laws such as the Toxic Substances Control Act. Asbestos mining has historically contributed to widespread exposure and contamination of products and environments. International treaties, such as the Rotterdam Convention, and the global ban movement have sought to eliminate asbestos use worldwide, with the European Union implementing a comprehensive ban on all forms of asbestos since 2005. Ensuring chemical safety is essential when evaluating asbestos and its substitutes to prevent health risks and manage hazardous materials responsibly.
Asbestos technically refers to a group of fibrous minerals, not just one. Scientists have grouped asbestos into six identified types and two asbestos families. The first family is the amphibole family, which has a sharp and straight fiber structure that is easily inhaled. These are known as amphibole asbestos and include brown asbestos (amosite), blue asbestos (crocidolite asbestos), and other forms such as tremolite asbestos and anthophyllite asbestos. The five types of asbestos that are in the amphibole family are:
Amosite is commonly referred to as brown asbestos, while crocidolite asbestos is also known as blue asbestos. Amphibole asbestos is characterized by its straight, needle-like fibre bundles, which differ from the curly chrysotile fibres found in the serpentine family. These fibre bundles are composed of flexible, easily separable fibres that form polyfilamentous arrangements, contributing to their unique physical properties. Asbestiform minerals are silicate minerals that occur in a fibrous habit, and asbestos fibre types differ in their chemical and physical properties, such as crystallinity, hardness, and melting point. The differences in asbestos fibre types and their physical properties influence their health risks. Amphibole fibres generally have greater relative potency in causing diseases like mesothelioma and lung cancer compared to chrysotile fibres, due to their durability and biopersistence.
Chrysotile asbestos, also known as white asbestos, is the only type of asbestos in the serpentine family. Serpentine asbestos consists of curly fibers and a layered structure. It is the most commonly used and most commercialized type of asbestos, making up an estimated 90 to 95 percent of all asbestos still found in the U.S. Before the use of asbestos was regulated, it became popular among manufacturers due to its versatility and heat-resistant properties. Products using chrysotile asbestos are still manufactured in some countries.
Chrysotile asbestos, commonly referred to as white asbestos, is the most prevalent form of asbestos used in industrial and commercial applications worldwide. As a member of the serpentine group, chrysotile is distinguished by its curly, flexible fibers and unique chemical composition—hydrated magnesium silicate, with the formula Mg₃(Si₂O₅)(OH)₄. This combination of magnesium, silicon, and oxygen, along with trace elements like iron and calcium, gives chrysotile asbestos its remarkable physical and chemical properties.
The chemical properties of chrysotile asbestos have made it highly sought after in various industries. Its fibers are known for their high tensile strength, flexibility, and resistance to heat, fire, and chemical corrosion. These characteristics allowed chrysotile to be widely incorporated into insulation materials, building materials, brake linings, and other asbestos containing materials. In particular, its ability to withstand high temperatures and its durability made it a staple in construction materials, cement products, and even in certain consumer goods.
Despite its industrial advantages, the use of chrysotile asbestos comes with significant health risks. When asbestos containing materials are disturbed, tiny asbestos fibers can become airborne and easily inhaled. Prolonged or repeated asbestos exposure can lead to serious health hazards, including lung cancer, malignant mesothelioma, ovarian cancer, and other asbestos related diseases. The World Health Organization and the International Agency for Research on Cancer have classified all forms of asbestos, including chrysotile, as carcinogenic to humans.
In response to these health effects, regulatory bodies such as the Environmental Protection Agency have established strict regulations for the handling, removal, and disposal of asbestos containing products. Many countries have banned or severely restricted the use of chrysotile asbestos, but it is still used in some developing countries where regulations may be less stringent. This ongoing use continues to put workers and the public at risk, especially in industries that manufacture or handle asbestos containing materials.
To protect human health and reduce the incidence of asbestos related diseases, there is a global push for the adoption of safer substitute materials and the complete removal of asbestos from new products. The World Health Organisation and other international agencies emphasize the importance of minimizing asbestos use and enforcing strict occupational safety standards to protect workers and the general public from the dangers of asbestos fibers.
In summary, while the chemical properties of chrysotile asbestos have made it a valuable material in various industrial applications, the health risks associated with asbestos exposure far outweigh its benefits. Continued vigilance, strict regulations, and the promotion of safer alternatives are essential to safeguarding public health and preventing future cases of lung cancer, pleural mesothelioma, and other asbestos-related diseases.
All six types of asbestos are dangerous carcinogens. Exposure to any type in any amount can result in illnesses and diseases such as asbestosis, mesothelioma, lung cancer, ovarian cancer, laryngeal cancer, and respiratory conditions. These ailments take years – often decades – to develop and show symptoms after the date of asbestos exposure.
Chrysotile asbestos is often viewed as the most dangerous type because of how often it was used in products and materials. This makes it more likely to present a hazard to the public. People exposed to chrysotile asbestos are at risk of developing these diseases. If you inhale, ingest or are otherwise exposed to chrysotile asbestos, the particles may become permanently lodged within your body.
If you breathe in asbestos dust, for example, the fibers could become stuck in the lining that surrounds your lungs (the pleura). Asbestos fibres can penetrate and accumulate in lung tissue, leading to damage. Over time, these fibers can cause irritation and scar tissue that can become cancerous (pleural mesothelioma). Exposure to chrysotile asbestos can also cause many other serious and irreversible health problems, including laryngeal cancer.
Inhaled asbestos fibres are responsible for the development of these serious health conditions.
Unfortunately, even after the U.S. stopped manufacturing items with asbestos, many buildings and products still contain chrysotile and other types of asbestos. Chrysotile may be found in a wide range of asbestos products and asbestos containing material, including:
Some items right in your home may contain asbestos. If you believe your home or the products that you use could contain chrysotile or another type of asbestos, hire a professional for safe removal and asbestos disposal. Asbestos is often combined with other materials, such as Portland cement, plastics, and resins, to create a variety of asbestos products that may still pose health risks.
Educating yourself on the dangers of asbestos and where you are most likely to encounter it in your life can help you avoid exposure. There are certain times and places where you may be more at risk of being exposed to asbestos, such as during the demolition or renovation of an older building, or if you work in the construction or automotive industry.
If you are in one of these situations, take steps to protect yourself from exposure. Wear a HEPA respirator, for example, to avoid breathing in tiny asbestos fibers. Use gloves and clothes that you are prepared to throw away so that you don’t bring asbestos home with you on your clothing. If you believe that you are in a position where you could be exposed to asbestos, contact a trained professional to safely handle the situation.
If exposure to chrysotile or any other type of asbestos results in a diagnosis of mesothelioma, contact an attorney for a free consultation about your legal options. You may have grounds to file a lawsuit for preventable asbestos exposure.
