What is Asbestos?

According to the Asbestos Network, asbestos actually refers to several naturally occurring minerals. These minerals have been used in commercial products to increase strength and flexibility. The Asbestos Network claims that these minerals are a mix of metals, silicon, oxygen, and hydrogen. Asbestos, like coal or gold is mined. Some of the countries that mine asbestos include the United Sates, Canada, South America and the former Soviet Union.

Types of Asbestos

Asbestos is not just one substance; in fact it can be divided into several different types, and these types can be divided into two basic groups. These two groups are serpentine and amphibole. Environmental Health and Safety claims that the serpentine group only contains one member: chrysotile. This type of asbestos is the most common form found in buildings and is also known as “white asbestos.”

Both the Asbestos Network and Environmental Health and Safety list five different types of asbestos within the amphibole group. These five include amosite, crocidolite, anthophyllite, tremolite, and actinolite. Amosite is the second most prevalent type found in building materials and is also referred to as “brown asbestos.” Crocidolite, “blue asbestos,” is found in structures where the materials need to be safe from high temperatures. The final three, anthyphyllite, tremolite, and actinolite, are rarely found.

Problems Related to Asbestos

The Asbestos Network explains that contact with asbestos can cause diseases such as asbestos lung cancer and mesothelioma. The fibrous nature of asbestos causes much of the problem. The fibers may get caught in the lungs and create lung damage. Or, they may even be swallowed and become lodged in membranes of the gastrointestinal track, according to the Asbestos Network. Again, this could lead to cancer of the lungs or of the GI tract. So while it may be thought that the lungs are the only place that can be damaged, it is other parts of the body can be negatively affected by asbestos.

Who is at Risk?

According to the Asbestos Network, the “dose” of asbestos that a person is exposed to equals the combination of the concentration, or the amount of asbestos in the air, and the duration, or the length of time that a person is exposed to asbestos. The more asbestos inhaled, the greater the chance of damage to lungs or other internal organs. Also, the Network says that cigarette smoking increases the likelihood of contracting an asbestos disease as it decreases the general health of the lungs. The Asbestos Network also lists several occupations that may be more likely to suffer from asbestos created diseases. These occupations include construction work, ship building, railroad working and automobile engineers.

How To Avoid It

There are several things that those who work around asbestos can do to limit their contact with the cancer causing fibers. The American Lung Association of Georgia insists on no eating or drinking while you are working. The Association also urges workers not to smoke and to follow proper guidelines when handling asbestos. Employers that place their employees in asbestos filled areas should have the employees properly trained on how to handle the substance, as well as how to avoid interacting with it.

Is Asbestos Exposure a Crouching Tiger? by Dr. Phil Hariram

October 17th, 2008 by admin

Asbestos is a substance found naturally. It is made of strong flexible fibres. It was used extensively in industry because the fibres are not affected by heat or chemicals and a poor conductor of electricity. It is estimated that over 5,000 products have or had asbestos in them.

Of the six types of asbestos, only four are used commercially. These are chrysotile, crocidolite, amosite and anthrophyllite. Of these, crysotile or white asbestos accounts for 99% used in USA. In it natural state or well contained and maintained in products, asbestos do not pose a real hazard. It is when asbestos is broken down and fibres are released that there is concern.

Asbestos fibres are very thin and sharp. The fibre is 2,000 times thinner than a human hair. It measures under 0.3 microns or one millionth of a millimetre in diameter and five microns in length. It is not visible with the naked eye or through a microscope.

When released, the fibres remain in the atmosphere for a long time and can be carried great distances. When the fibres are inhaled, they stick to the lung tissue and are not expelled by breathing out or coughing. Some remain in the lungs, others gravitate into the pleural lining.

Asbestos exposure can lead to disease and develops over a long period of time. Asbestos related diseases are asbestosis, pleural plaques and lung cancers. The lung cancer can be either cancer of the lung itself or mesothelioma, a cancer of the lung lining. These cancers can take between 20 and 50 years to develop.

A recent article in a UK Newspaper highlighted the case of a Hospital Consultant who developed mesothelioma. He cannot recall any exposure to asbestos. It may well be that he was inadvertently exposed to asbestos without his knowledge i.e. such as living in the vicinity of a factory that leaked asbestos into the atmosphere.

Professor Peto has shown that new cases of mesothelioma will continue to increase in the early part of the twenty first century. He also said, “Every single person in the UK has asbestos in their lungs. It is the level of exposure that is important.”

We also know that people who has a history of asbestos exposure has a greater risk of lung cancer if they smoked. In a survey in 1992, 2602 individuals with lung cancer were interviewed. One in eight was exposed to asbestos and of these a third still smoked. A US study suggested that non-smokers exposed to asbestos have a five times greater risk of lung cancer. If they smoked, then the risk increased by a factor of 11. Smoking and asbestos exposure increases the risk of developing lung cancer to 52 times that of the general population.

At present no one knows how many lung cancers are due to asbestos exposure because of the long latency period and that cigarette smoking remains the major cause. Mesothelioma, however, is caused by asbestos exposure and this has been the basis of numerous high value legal claims.

As for the future, in the USA and Europe, asbestos related diseases will gradually increase to a peak. Of concern, however, are areas of conflict. In the Middle East, when a building was bombed, or when numerous buildings were bombed during the invasion of Iraq, do we have any idea how much asbestos was released into the atmosphere?

We are, however, certain that during the 9/11 disaster, asbestos fibres were released. When the Twin Tower collapsed, there were 400 tons of asbestos in the structure. The toxic cloud that hung over Manhattan, contained high level of asbestos. It is estimated that over 100,000 people suffered asbestos exposure. The greatest exposure was amongst first responders. Deborah Reeve was the first to die from asbestos related disease after 9/11. She was a first responder and paramedic. She died in March 2005 from mesothelioma. This concerned experts because mesothelioma takes a very long time to develop. They concluded that her exposure must have been excessive.

A study result showed that 70% of recovery and rescue workers who were active during and after the World Trade Centre collapse had some form of respiratory problem. A six year follow up study showed that sufferers with respiratory problems continue to have the same ailments.

“In the six years since the attacks,” Nadler said, “We have accumulated a mountain of evidence that thousands of those exposed are suffering from chronic respiratory disease and, increasingly, a variety of rare cancers.”

Hopefully, as experts predict, within the next few years asbestos related diseases will peak and the annual new cases will drop. If not, could it be mankind’s crouching tiger?

Mesothelioma and Asbestos: a Glossary of Related Terms and Definitions

October 14th, 2008 by admin

Understanding the terminology commonly associated with mesothelioma and asbestos while holding a conversation with your doctor or other specialist will help you to relate to what they’re saying and make more informed decisions about how to proceed.

Below are some of the most common terms used when describing, diagnosing or treating mesothelioma.

1. Asbestos

A natural mineral that is commonly used in construction materials or similar products due to its high level of heat resistance and durability. It is a fibrous silicate mineral, and exposure to asbestos over an extended period of time can cause mesothelioma, lung cancer or asbestosis.

2. Asbestosis

A serious health condition in which there is scar tissue present in the lungs as a result of inhaling asbestos dust and fibers.

3. Mesothelioma

A rare, cancerous condition most often caused by exposure to asbestos. This is a malignant cancer tumor found in the mesothelium of the abdomen or lungs.

4. Mesothelium

Tissue which forms a lining around several organs such as the abdomen, and also the chest area. The fluid produced by this tissue helps to protect and mobilize organs.

5. Invasive cancer

A cancer that spreads from one point to another in the body.

6. Epidemiology

Statistics of diseases and their causes among a population.

7. Carcinoma

Tissue that is diagnosed malignant. This is normally a tumor.

8. Tremolite

A type of asbestos which has flexible fibers.

9. Serpentine Asbestos

A type of asbestos which has curly fibers that is of a tiered structure. The most commonly used form of asbestos in the U.S., called “Chrysotile”, and is a type of serpentine asbestos.

10. Pneumoconiosis

Also known as fibrosis of the lungs, where the lungs have been scarred due to frequent inhalation of asbestos.

If you are up to date with the terms and the words when dealing with mesothelioma, it allows you to be better prepared when and if you have to deal with it. If you need to speak to a mesothelioma attorney or lawyer, you will be able to understand some of the terms they use when talking about your case.

Again if you have to see your doctor, you will be able to understand what they are talking about to a certain extent. Mesothelioma can be very complex and confusing for anyone. Throw in the emotions of being involved or at having mesothelioma and everything can become very confusing.

This guide will hopefully help to clear up any confusion you may have.
