What Is Asbestos?
Asbestos is a group of six naturally occurring minerals. These minerals, which form as fibers, are broken into two categories: serpentine and amphibole. The most common form is known as chrysotile, or “white asbestos,” and falls under the serpentine category. It was most widely used in the United States for insulation and as a durable building material. The other five types — actinolite, amosite, anthophyllite, crocidolite, and tremolite — are amphibole and can be found in mineral deposits all over the world.
History of Asbestos Use
Asbestos has been used for centuries due to its ability to withstand fire. Early evidence of its use was its presence in pottery (possibly used to strengthen clay) found in Finland and dated around 2500 B.C.E. Other cultures and civilizations utilized asbestos throughout time, but it wasn’t until the 19th century that the material was used for modern industries. For instance, a textile manufacturer in Italy used asbestos to strengthen fabrics and book covers.
As more industries learned of asbestos’s heat resistance, flexibility, and durability, it became more popular and heavily mined. While at one time it was feared that the world was running low on the mineral, deposits found in Canada, Russia, and South Africa were able to replenish the supply. The demand continued to grow at the beginning of the 20th century.
A development that allowed inexpensive mass production of asbestos-cement panels and pipe caused a significant increase in demand. This new technology allowed for the widespread use of asbestos in building materials and water and waste lines. Along with the rise of the automobile, the U.S. was using 43 percent of the world’s 109,000 metric tons of the world’s production by 1910.
The use of asbestos exploded leading up to and through World War II. It seemed like the perfect solution to keep up with wartime manufacturing demands and to rebuild cities after the war. It wasn’t until the early 1960s that a connection between asbestos exposure and cancer was proven and the demand for asbestos in the U.S. declined.
Where Is Asbestos Found?
Asbestos was used commercially and industrially, and many buildings still contain the carcinogen today, including some built as recently as 2004. Due to this, certain occupations, like construction and firefighting, pose a greater risk of exposure.
Not all of these exposures happen around old buildings and equipment. Outside of artificial structures, asbestos exists in rocks, soil, and water. The primary source is when asbestos-containing rocks break or erode. Fibers can then make their way into the soil and nearby bodies of water. However, although it is possible to develop mesothelioma from exposure to asbestos found in nature, the greater danger is using artificial products that contain it. This is because asbestos is not dangerous unless inhaled or ingested, which generally does not occur unless the material is disturbed.
Common Asbestos Products
Before the dangers of asbestos exposure became widely known, it was popular to use in a variety of products to increase durability and heat resistance. These include:
- Paper and paper products
- Building materials
- Brake pads
- Corrugated sheeting
- Roofing materials and shingles
- Siding shingles
- Vinyl tiles
- Ceiling tiles
- Corrosive chemical containers
- Heat-protective pads
- Laboratory furniture
- Pipe coverings
- Sealants and caulking
- Textiles and heat-resistant fabrics
- Textured paints
- Patching compounds
- Woodburning stoves
While most of these products are off the market or no longer made with asbestos, there was no requirement to remove or dispose of products that were already contaminated. That is why some buildings, roads, and products, especially those built before 1975, are more likely to contain the carcinogen and could pose a threat to people nearby during construction or demolition.
The Dangers of Asbestos Exposure
Today, the dangers of asbestos are well documented. Every form of it and similar minerals have been labeled as potent carcinogens by the Environmental Protection Agency (EPA), the International Agency for Research on Cancer (IARC), and the National Toxicology Program (NTP).
Asbestos and Mesothelioma
Considering its long history, asbestos’s effect on the human body was a relatively recent discovery. When disturbed, microscopic fibers can fly into the air. This makes it easy for those fibers to enter the mouth, esophagus, and lungs. Once inside, the thorn-like fibers will then attach to the inside of the body — particularly the mesothelium, a protective layer that lubricates the organs in the chest and abdomen. When these barbs become lodged in the mesothelium, they create friction against the organs. This friction will eventually form scars that can grow and develop into cancerous cells. This disease is known as mesothelioma.
Pleural mesothelioma is the most common kind of this rare cancer. This is because it affects the pleural lining of the lungs, the easiest area for asbestos fibers to reach. It is more unusual for the mineral to affect the peritoneal lining in the abdomen, and even rarer for it to reach the pericardial lining around the heart.
Other Asbestos-Related Diseases
While mesothelioma is one of the better-known diseases to come out of asbestos exposure, the group of carcinogens has also been known to cause other forms of cancer and other diseases. The first documented case of asbestos-caused disease was in 1927, when the term “asbestosis” was coined. Still, despite this discovery, there wasn’t enough evidence at the time to prove a definitive connection between asbestosis and asbestos.
Today, we have a better understanding of what asbestos does in the body. Clear links have been established between asbestos exposure and certain cancers. This includes mesothelioma, as well as other cancers, such as:
- Lung cancer
- Larynx cancer
- Ovarian cancer
As a carcinogen, it is suspected that asbestos is also responsible for other forms of cancer. However, the ties between exposure and the development of these cancers later in life are not as clear. These cancers include:
- Throat cancer
- Stomach cancer
- Colon cancer
- Rectal cancer
What to Do After You’ve Been Exposed to Asbestos
Unfortunately, there is nothing to be done after immediate asbestos exposure, given that the latency period before cancer develops from asbestos can range from 10 to 60 years depending on how it traveled. There is also little evidence of a single asbestos exposure causing disease, as it is likely that most Americans have come into contact with the industrial material at least once. However, if you have worked regularly in old, decaying buildings or served in the military, you have probably been exposed repeatedly for longer periods of time. If this is the case and you find yourself exhibiting symptoms of mesothelioma, you may be able to take legal action.
