There are three exposure routes for asbestos fibers: (1) inhalation via the respiratory system (2) ingestion via the mouth associated with asbestos fibers in drinking water and (3) skin contact. Asbestos has been known to cause a number of disabling and fatal diseases such as asbestosis, lung cancer, mesothelioma and pleural plaques. There is no safe level of exposure to asbestos; therefore, all exposure to asbestos should be avoided.

Asbestos exposure is responsible for a number of diseases that range from being debilitating to incurably fatal. Some of the more common asbestos-related diseases include: Malignant mesothelioma and asbestos lung cancer are the only two asbestos-related diseases that are directly fatal. Asbestosis is a type of inflammatory lung disease that can cause a decrease in total lung capacity and lead to heart failure; however, the disease itself is not a direct cause of death.

Almost everyone is exposed to low levels of asbestos in their lives. It exists in the air at extremely low concentration; levels are highest in urban and industrial areas. These fibers are released into the air during demolition work, remodeling, or other activity in which the material containing asbestos is disturbed. Asbestos may occur in tap water where such water passes through cement pipes containing the substance.

When inhaled asbestos can have very serious effects on your health. The greater the exposure to asbestos, the greater the risk for an asbestos- related disease there is. Currently, there is no known level of asbestos exposure deemed safe. It is unknown the levels of asbestos that is considered safe. Asbestos causes asbestosis and mesothelioma, but because of the latency period between the time of exposure to asbestos, the diseases do not surface for 20-40 years.

Asbestosis-a chronic lung ailment that can produce shortness of breath, coughing, and permanent lung damage;

Secondhand smoke exposure is a known risk factor for lung cancer. Approximately 3,000 lung cancer deaths occur each year among adult non-smokers in the United States as a result of exposure to secondhand smoke. Secondhand smoke is also linked to nasal sinus cancer. Some research suggests an association between secondhand smoke and cancers of the cervix, breast, and bladder. However, more research is needed in order to confirm a link to these cancers.

No immediate symptoms. Based on an updated Assessment of Risk for Radon in Homes, radon in indoor air is estimated to cause about 21,000 lung cancer deaths each year in the United States. Smokers are at higher risk of developing Radon-induced lung cancer. Lung cancer is the only health effect which has been definitively linked with radon exposure. Lung cancer would usually occur years (5-25) after exposure.

Yes, the malnourishment and purging associated with Anorexia often cause other significant health problems. People with Anorexia are often diagnosed with anemia, cardiovascular (heart and blood circulation) problems such as hypotension (low blood pressure) and irregular heart beat (arrhythmia), tooth decay from repeated vomiting, poor kidney functioning, and osteoporosis (a decrease in the size and strength of bone).

In order to be exposed to PAHs at the school, you must come into direct contact with the contaminated soil (for example, touching the soil, eating soil particles on hands or food, or breathing airborne soil particles). Several PAHs have been shown to cause cancer in laboratory animals and in people after long periods of exposure at high levels. Studies in animals have also shown that PAHs can cause harmful effects on skin, body fluids, and the immune system.

We are exposed to mould and mould spores throughout our day in our natural environment. This does not mean that if you find mould that you should not take basic precautions such as gloves and a mask, but the concern is greater for people with compromised or suppressed immune systems where exposure can lead to problems with allergic reactions or infection. The type and concentration of mould and the method of exposure will have an effect.

Asbestos diseases may be placed in two categories. Cancerous and noncancerous. Asbestos is a potent carcinogen. The primary forms of cancer of the lung which have been linked to asbestos exposure are: Mesothelioma usually starts in the pleura of the lung, which is an outside lining of the lungs. To see where the pleura is, click here. There is also a form of mesothelioma called peritoneal mesothelioma, which is not a cancer of the lung, but the peritoneum, which is the area below the lung.

Molds can cause many health ailments. The most common symptom associated with exposure to elevated levels of fungal spores or mold is Allergies. Other symptoms are; asthma, edema, bronchiospasms, pulmonary emphysema, candida vaginitis, thrush, infections in the human skin, nails, eyes, nose, sinuses, tongue, throat, esophagus, and the entire digestive tract and fungal related ear infections. Molds can also be acutely toxic to the liver, brain, kidneys, lungs and heart.

The answer to this question is the subject of ongoing scientific and policy debate. We do know very high levels of dioxin in blood (hundreds to thousands of times higher than people normally experience) increase the likelihood of developing chloracne, a temporary skin condition which can be severe in some cases. Scientists convened by WHO reviewed the animal toxicity data on dioxin in a recent report (Food Additives Contam., 17: 223-240, 2000).

Some symptoms might include a runny nose, sneezing, itchy or watery eyes, and respiratory complaints. Symptoms often resemble those of allergies and asthma.

From studies of people who were exposed to asbestos in factories and shipyards, we know that breathing high levels of asbestos fibers can lead to an increased risk of lung cancer. Most people exposed to small amounts of asbestos, as we all are in our daily lives, do not develop health problems. However, if disturbed, asbestos material may release asbestos fibers, which can be inhaled into the lungs. The fibers can remain there for a long time, increasing the risk of disease.

There is a latency period between the time of exposure to asbestos and the manifestation of asbestos diseases that generally varies between several years and several decades. Many asbestos cancers will not arise in a victim until twenty years or more after first exposure to asbestos. Typically, asbestosis or pleural plaques will not occur until at least ten to twenty years after first exposure.
