The European mesothelioma epidemic. (1/1116)Projections for the period 1995-2029 suggest that the number of men dying from mesothelioma in Western Europe each year will almost double over the next 20 years, from 5000 in 1998 to about 9000 around 2018, and then decline, with a total of about a quarter of a million deaths over the next 35 years. The highest risk will be suffered by men born around 1945-50, of whom about 1 in 150 will die of mesothelioma. Asbestos use in Western Europe remained high until 1980, and substantial quantities are still used in several European countries. These projections are based on the fit of a simple age and birth cohort model to male pleural cancer mortality from 1970 to 1989 for six countries (Britain, France, Germany, Italy, The Netherlands and Switzerland) which together account for three-quarters of the population of Western Europe. The model was tested by comparing observed and predicted numbers of deaths for the period 1990-94. The ratio of mesothelioma to recorded pleural cancer mortality has been 1.6:1 in Britain but was assumed to be 1:1 in other countries. (+info)
Macrophage plasminogen activator: induction by asbestos is blocked by anti-inflammatory steroids. (2/1116)Intraperitoneal injection of asbestos fibres into mice induces the formation of exudates containing macrophages that produce plasminogen activator. Like-wise, in vitro addition of asbestos to macrophage cultures stimulates plasminogen activator secretion; the synthesis and secretion of lysozyme and lysosomal enzymes are not changed under these conditions. The enhanced secretion of plasminogen activator by macrophages exposed to asbestos is suppressed by low concentrations of anti-inflammatory steroids. (+info)
A historical cohort mortality study of workers exposed to asbestos in a refitting shipyard. (3/1116)To investigate the risks of developing asbestos-related diseases we conducted a historical cohort mortality study on 249 ship repair workers (90 laggers and 159 boiler repairers) in a single U.S. Navy shipyard in Japan. We successfully identified the vital status of 87 (96.7%) laggers and 150 (94.3%) boiler repairers, and, of these, 49 (56.3%) and 65 (43.3%) died, respectively, during the follow-up period from 1947 till the end of 1996. Our in-person interviews with some of the subjects clarified that asbestos exposure was considered to be substantially high in the 1950-60s, decreased thereafter gradually but remained till 1979 in the shipyard. The laggers, who had handled asbestos materials directly, showed a significantly elevated SMR of 2.75 (95% C.I.: 1.08-6.48) for lung cancer. The risk developing the disease was greater in the laggers after a 20-year latency (SMR = 3.42). Pancreatic cancer yielded a greater SMR than unity (7.78, 90% C.I.: 2.07-25.19) in a longer working years group. Four laggers died from asbestosis. The boiler repairers, who had many chances for secondary exposure to asbestos and a few for direct exposure, showed no elevation of the SMR of lung cancer overall, but there was a borderline statistically significant SMR of 2.41 (90% C.I.: 1.05-5.45) in a longer working years group. One boiler repairer died from mesothelioma and four from asbestosis. (+info)
Reduced tumor necrosis factor-alpha and transforming growth factor-beta1 expression in the lungs of inbred mice that fail to develop fibroproliferative lesions consequent to asbestos exposure. (4/1116)Tumor necrosis factor (TNF)-alpha and transforming growth factor (TGF)-beta mRNA and protein expression and the degree of fibroproliferative response to inhaled asbestos fibers are clearly reduced in the 129 inbred mouse strain as compared with typical fibrogenesis observed in the C57BL/6 inbred strain. The C57BL/6 mice showed prominent lesions at bronchiolar-alveolar duct (BAD) junctions where asbestos fibers deposit and responding macrophages accumulate. The 129 mice, however, were generally indistinguishable from controls even though the numbers of asbestos fibers deposited in the lungs of all exposed animals were the same. Quantitative morphometry of H&E-stained lung sections comparing the C57BL/6 and 129 mice showed significantly less mean cross-sectional area of the BAD junctions in the 129 animals, apparent at both 48 hours and 4 weeks after exposure. In addition, fewer macrophages had accumulated at these sites in the 129 mice. Nuclear bromodeoxyuridine immunostaining demonstrated that the number of proliferating cells at first alveolar duct bifurcations and in adjacent terminal bronchioles was significantly reduced in the 129 strain compared with C57BL/6 mice at 48 hours after exposure (P < 0.01). TNF-alpha and TGF-beta1 gene expression, as measured by in situ hybridization, was reduced in the 129 mice at 48 hours after exposure, and expression of TNF-alpha and TGF-beta1 protein, as measured by immunohistochemistry, was similarly reduced or absent in the 129 animals. We postulate that the protection afforded the 129 mice is related to reduction of growth factor expression by the bronchiolar-alveolar epithelium and lung macrophages. (+info)
A retired shipyard worker with rapidly progressive pulmonary interstitial fibrosis. (5/1116)We present a case of progressive interstitial fibrosis in a retired shipyard worker who was exposed to asbestos during the postwar era of the late 1940s and 1950s, when asbestos exposures in the workplace were not regulated. Forty years later, at 63 years of age, the patient presented with restrictive lung disease. The patient was diagnosed with asbestos-related pleural disease and parenchymal asbestosis. He remained stable for the next 7 years, but then he began to manifest rapid clinical progression, which raised the possibility of an unusual variant of asbestosis, a concomitant interstitial process, or an unrelated disease. Lung biopsy was not undertaken because of the patient's low pulmonary reserve and limited treatment options. An empiric trial of oral steroids was initiated, but his pulmonary status continued to deteriorate and he died of pulmonary failure at 72 years of age. Many diseases result in pulmonary interstitial fibrosis. Ideally, open lung biopsy should be performed, but this procedure inevitably causes complications in many patients with end-stage restrictive lung disease. Furthermore, while the presence of asbestos bodies in tissue sections is a sensitive and specific marker of asbestos exposure, neither this finding nor any other charge is a marker indicative of asbestosis or the severity of asbestosis. With the enactment of the Asbestos Standard in the United States, asbestos exposures have been decreasing in this country. However, industries that produce asbestos products and wastes continue to expand in developing countries. Prevention of asbestos-related lung disease should be a global endeavor, and asbestos exposures should be regulated in both developed and developing countries. (+info)
Magnetic resonance appearance of asbestos-related benign and malignant pleural diseases. (6/1116)OBJECTIVES: This study describes the magnetic resonance findings of benign and malignant pleural diseases in asbestos-exposed subjects. METHODS: Thirty patients with a history of asbestos exposure and pleural lesions in chest X-rays and computed tomography scans were examined with a 0.5- and a 1.5-T magnetic resonance unit. The examination protocol included cardiac-gated proton density and T2-weighted images, unenhanced and enhanced (Gd-DTPA; 0.1 mmol/ kg) T1-weighted images in the axial plane and sometimes in another orthogonal plane (sagittal or coronal or both). All the magnetic resonance images were reviewed by 3 experienced observers, who visually evaluated morphologic features, signal intensity, and contrast enhancement of pleural lesions. The diagnosis was established by means of percutaneous biopsy, thoracotomy, and combined clinical and radiological follow-up for at least 3 years. RESULTS: Eighteen patients affected with multiple pleural plaques showed low signal intensity on both unenhanced and enhanced T1-weighted and proton density and T2-weighted images. In 2 of these patients an acute pleural effusion was observed. All the malignant lesions (11 mesotheliomas) and a solitary benign pleural plaque revealed high signal intensity on the proton density and T2-weighted images and inhomogeneous contrast enhancement in the postcontrast T1-weighted images. The sensitivity, specificity, and diagnostic accuracy of the magnetic resonance imaging in classifying a lesion as suggestive of malignancy were 100%, 95% and 97%, respectively. CONCLUSIONS: The results point out 2 magnetic resonance signal intensity patterns for asbestos-related pleural lesions: (i) low-signal intensity on unenhanced and enhanced T1-weighted and proton density and T2-weighted images for benign plaques and (ii) nonhomogeneous hyperintensity in T2-weighted and enhanced T1-weighted images for malignant mesotheliomas.

Environmental pathology: new directions and opportunities. (7/1116)The National Institute of Environmental Health Sciences (NIEHS) supports a number of training programs for predoctoral and postdoctoral (D.V.M., M.D., Ph.D.) fellows in toxicology, epidemiology and biostatistics, and environmental pathology. At the Experimental Biology meeting in April 1997, the American Society of Investigative Pathology (ASIP) sponsored a workshop including directors, trainees, and other interested scientists from several environmental pathology programs in medical and veterinary colleges. This workshop and a related session on "Novel Cell Imaging Techniques for Detection of Cell Injury" revealed advances in molecular and cell imaging approaches as reviewed below that have a wide applicability to toxicologic pathology.

Asbestos induces activator protein-1 transactivation in transgenic mice. (8/1116)Activation of activator protein (AP-1) by crocidolite asbestos was examined in vitro in a JB6 P+ cell line stably transfected with AP-1-luciferase reporter plasmid and in vivo using AP-1-luciferase reporter transgenic mice. In in vitro studies, crocidolite asbestos caused a dose- and time-dependent induction of AP-1 activation in cultured JB6 cells. The elevated AP-1 activity persisted for at least 48 h. Crocidolite asbestos also induced AP-1 transactivation in the pulmonary and bronchial tissues of transgenic mice. AP-1 activation was observed at 2 days after intratracheal instillation of the mice with asbestos. At 3 days postexposure, AP-1 activation was elevated 10-fold in the lung tissue and 22-fold in bronchiolar tissue as compared with their controls. The induction of AP-1 activity by asbestos appeared to be mediated through the activation of mitogen-activated protein kinase family members, including extracellular signal-regulating protein kinase, Erk1 and Erk2. Aspirin inhibited asbestos-induced AP-1 activity in JB6 cells. Pretreatment of the mice with aspirin also inhibited asbestos-induced AP-1 activation in bronchiolar tissue. The data suggest that further investigation of the role of AP-1 activation in asbestos-induced cell proliferation and carcinogenesis is warranted. In addition, investigation of the potential therapeutic benefits of aspirin in the prevention/amelioration of asbestos-induced cancer is justified. (+info)
The symptoms of mesothelioma can vary depending on the location of the cancer, but they may include:
* Shortness of breath or pain in the chest (for pleural mesothelioma)
* Abdominal pain or swelling (for peritoneal mesothelioma)
* Fatigue or fever (for pericardial mesothelioma)
* Weight loss and night sweats
There is no cure for mesothelioma, but treatment options may include surgery, chemotherapy, and radiation therapy. The prognosis for mesothelioma is generally poor, with a five-year survival rate of about 5% to 10%. However, the outlook can vary depending on the type of mesothelioma, the stage of the cancer, and the patient's overall health.
Asbestos exposure is the primary risk factor for developing mesothelioma, and it is important to avoid exposure to asbestos in any form. This can be done by avoiding old buildings and products that contain asbestos, wearing protective clothing and equipment when working with asbestos, and following proper safety protocols when handling asbestos-containing materials.
In summary, mesothelioma is a rare and aggressive form of cancer that develops in the lining of the heart or abdomen due to exposure to asbestos. It can be difficult to diagnose and treat, and the prognosis is generally poor. However, with proper medical care and avoidance of asbestos exposure, patients with mesothelioma may have a better chance of survival.
Some common types of pleural diseases include:
1. Pleurisy: This is an inflammation of the pleura that can be caused by infection, injury, or cancer. Symptoms include chest pain, fever, and difficulty breathing.
2. Pneumothorax: This is a collection of air or gas between the pleural membranes that can cause the lung to collapse. Symptoms include sudden severe chest pain, shortness of breath, and coughing up blood.
3. Empyema: This is an infection of the pleural space that can cause the accumulation of pus and fluid. Symptoms include fever, chills, and difficulty breathing.
4. Mesothelioma: This is a type of cancer that affects the pleura and can cause symptoms such as chest pain, shortness of breath, and weight loss.
5. Pleural effusion: This is the accumulation of fluid in the pleural space that can be caused by various conditions such as infection, heart failure, or cancer. Symptoms include chest pain, shortness of breath, and coughing up fluid.
Pleural diseases can be diagnosed through various tests such as chest X-rays, CT scans, and pleuroscopy (a minimally invasive procedure that uses a thin tube with a camera and light on the end to examine the pleura). Treatment options vary depending on the underlying cause of the disease and can include antibiotics, surgery, or radiation therapy.
Benign pleural neoplasms include:
1. Pleomorphic adenoma: A rare, slow-growing tumor that usually occurs in the soft tissues of the chest wall.
2. Pneumoschisis: A condition where there is a tear or separation in the membrane that lines the lung, which can cause air to leak into the pleural space and create a benign tumor.
3. Pleural plaques: Calcified deposits that form in the pleura as a result of inflammation or injury.
Malignant pleural neoplasms include:
1. Mesothelioma: A rare and aggressive cancer that originates in the pleura, usually caused by exposure to asbestos.
2. Lung cancer: Cancer that spreads to the pleura from another part of the body, such as the lungs.
3. Metastatic tumors: Tumors that have spread to the pleura from another part of the body, such as the breast or colon.
Pleural neoplasms can cause a variety of symptoms, including chest pain, shortness of breath, coughing, and fatigue. Diagnosis is typically made through a combination of imaging tests, such as CT scans and PET scans, and a biopsy to confirm the presence of cancerous cells. Treatment options for pleural neoplasms depend on the type and stage of the tumor, and may include surgery, chemotherapy, and radiation therapy.
1. Asbestosis: a lung disease caused by inhaling asbestos fibers.
2. Carpal tunnel syndrome: a nerve disorder caused by repetitive motion and pressure on the wrist.
3. Mesothelioma: a type of cancer caused by exposure to asbestos.
4. Pneumoconiosis: a lung disease caused by inhaling dust from mining or other heavy industries.
5. Repetitive strain injuries: injuries caused by repetitive motions, such as typing or using vibrating tools.
6. Skin conditions: such as skin irritation and dermatitis caused by exposure to chemicals or other substances in the workplace.
7. Hearing loss: caused by loud noises in the workplace.
8. Back injuries: caused by lifting, bending, or twisting.
9. Respiratory problems: such as asthma and other breathing difficulties caused by exposure to chemicals or dust in the workplace.
10. Cancer: caused by exposure to carcinogens such as radiation, certain chemicals, or heavy metals in the workplace.
Occupational diseases can be difficult to diagnose and treat, as they often develop gradually over time and may not be immediately attributed to the work environment. In some cases, these diseases may not appear until years after exposure has ended. It is important for workers to be aware of the potential health risks associated with their job and take steps to protect themselves, such as wearing protective gear, following safety protocols, and seeking regular medical check-ups. Employers also have a responsibility to provide a safe work environment and follow strict regulations to prevent the spread of occupational diseases.
There are several types of lung neoplasms, including:
1. Adenocarcinoma: This is the most common type of lung cancer, accounting for approximately 40% of all lung cancers. It is a malignant tumor that originates in the glands of the respiratory tract and can be found in any part of the lung.
2. Squamous cell carcinoma: This type of lung cancer accounts for approximately 25% of all lung cancers and is more common in men than women. It is a malignant tumor that originates in the squamous cells lining the airways of the lungs.
3. Small cell lung cancer (SCLC): This is a highly aggressive form of lung cancer that accounts for approximately 15% of all lung cancers. It is often found in the central parts of the lungs and can spread quickly to other parts of the body.
4. Large cell carcinoma: This is a rare type of lung cancer that accounts for only about 5% of all lung cancers. It is a malignant tumor that originates in the large cells of the respiratory tract and can be found in any part of the lung.
5. Bronchioalveolar carcinoma (BAC): This is a rare type of lung cancer that originates in the cells lining the airways and alveoli of the lungs. It is more common in women than men and tends to affect older individuals.
6. Lymphangioleiomyomatosis (LAM): This is a rare, progressive, and often fatal lung disease that primarily affects women of childbearing age. It is characterized by the growth of smooth muscle-like cells in the lungs and can lead to cysts, lung collapse, and respiratory failure.
7. Hamartoma: This is a benign tumor that originates in the tissue of the lungs and is usually found in children. It is characterized by an overgrowth of normal lung tissue and can be treated with surgery.
8. Secondary lung cancer: This type of cancer occurs when cancer cells from another part of the body spread to the lungs through the bloodstream or lymphatic system. It is more common in people who have a history of smoking or exposure to other carcinogens.
9. Metastatic cancer: This type of cancer occurs when cancer cells from another part of the body spread to the lungs through the bloodstream or lymphatic system. It is more common in people who have a history of smoking or exposure to other carcinogens.
10. Mesothelioma: This is a rare and aggressive form of cancer that originates in the lining of the lungs or abdomen. It is caused by asbestos exposure and can be treated with surgery, chemotherapy, and radiation therapy.
Lung diseases can also be classified based on their cause, such as:
1. Infectious diseases: These are caused by bacteria, viruses, or other microorganisms and can include pneumonia, tuberculosis, and bronchitis.
2. Autoimmune diseases: These are caused by an overactive immune system and can include conditions such as sarcoidosis and idiopathic pulmonary fibrosis.
3. Genetic diseases: These are caused by inherited mutations in genes that affect the lungs and can include cystic fibrosis and primary ciliary dyskinesia.
4. Environmental diseases: These are caused by exposure to harmful substances such as tobacco smoke, air pollution, and asbestos.
5. Radiological diseases: These are caused by exposure to ionizing radiation and can include conditions such as radiographic breast cancer and lung cancer.
6. Vascular diseases: These are caused by problems with the blood vessels in the lungs and can include conditions such as pulmonary embolism and pulmonary hypertension.
7. Tumors: These can be benign or malignant and can include conditions such as lung metastases and lung cancer.
8. Trauma: This can include injuries to the chest or lungs caused by accidents or other forms of trauma.
9. Congenital diseases: These are present at birth and can include conditions such as bronchopulmonary foregut malformations and congenital cystic adenomatoid malformation.
Each type of lung disease has its own set of symptoms, diagnosis, and treatment options. It is important to seek medical attention if you experience any persistent or severe respiratory symptoms, as early diagnosis and treatment can improve outcomes and quality of life.
Mesothelial neoplasms are relatively rare compared to other types of cancer, but they can be aggressive and difficult to treat. The most common type of mesothelial neoplasm is malignant mesothelioma, which can arise from any of the three layers of mesothelium. Other less common types include benign mesothelioma and sarcomatoid mesothelioma.
The symptoms of mesothelial neoplasms vary depending on the location and size of the tumor. They may include chest pain, abdominal pain, difficulty breathing, or swelling in the affected area. Diagnosis is typically made through a combination of imaging studies (such as CT scans or PET scans) and biopsy, where a sample of tissue is removed from the tumor for examination under a microscope.
Treatment options for mesothelial neoplasms depend on the location, size, and stage of the tumor, as well as the patient's overall health. Surgery, chemotherapy, and radiation therapy may be used alone or in combination to treat the disease. Prognosis is generally poor for malignant mesothelioma, with a five-year survival rate of less than 10%. However, patients with benign mesothelioma have a better prognosis, with a five-year survival rate of up to 50%.
There are several types of pulmonary fibrosis, including:
1. Idiopathic pulmonary fibrosis (IPF): This is the most common and severe form of the disease, with no known cause or risk factors. It is characterized by a rapid decline in lung function and poor prognosis.
2. Connective tissue disease-associated pulmonary fibrosis: This type is associated with conditions such as rheumatoid arthritis, systemic lupus erythematosus, and scleroderma.
3. Drug-induced pulmonary fibrosis: Certain medications, such as amiodarone and nitrofurantoin, can cause lung damage and scarring.
4. Radiation-induced pulmonary fibrosis: Exposure to high doses of radiation, especially in childhood, can increase the risk of developing pulmonary fibrosis later in life.
5. Environmental exposures: Exposure to pollutants such as silica, asbestos, and coal dust can increase the risk of developing pulmonary fibrosis.
Symptoms of pulmonary fibrosis include shortness of breath, coughing, and fatigue. The disease can be diagnosed through a combination of imaging tests such as chest X-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI), as well as lung biopsy.
Treatment options for pulmonary fibrosis are limited and vary depending on the underlying cause of the disease. Medications such as pirfenidone and nintedanib can help slow the progression of the disease, while lung transplantation may be an option for advanced cases.
There are several forms of pneumoconiosis, including:
* Coal workers' pneumoconiosis (CWP): caused by inhalation of coal dust in coal miners.
* Silicosis: caused by inhalation of silica dust in workers such as quarry workers, miners, and others who work with silica-containing materials.
* Asbestosis: caused by inhalation of asbestos fibers, which can lead to inflammation and scarring of the lungs.
* Hypersensitivity pneumonitis: caused by exposure to specific organic dusts, such as those found in agricultural or woodworking settings.
The symptoms of pneumoconiosis can vary depending on the type and severity of the disease, but may include coughing, shortness of breath, fatigue, and fever. In severe cases, pneumoconiosis can lead to respiratory failure and other complications.
Diagnosis of pneumoconiosis typically involves a combination of physical examination, medical history, and diagnostic tests such as chest X-rays, CT scans, and lung function tests. Treatment for pneumoconiosis may include medications to manage symptoms, pulmonary rehabilitation, and measures to reduce exposure to the offending particles. In severe cases, lung transplantation may be necessary.
Prevention of pneumoconiosis is critical, and this involves implementing appropriate safety measures in workplaces where workers are exposed to dusts or other particles. This can include using respiratory protection equipment, improving ventilation, and reducing exposure to hazardous materials. Early detection and treatment of pneumoconiosis can help to slow the progression of the disease and improve outcomes for affected individuals.
Cocarcinogenesis can occur through various mechanisms, such as:
1. Synergistic effects: The combined effect of two or more substances is greater than the sum of their individual effects. For example, smoking and exposure to asbestos can increase the risk of lung cancer more than either factor alone.
2. Antagonism: One substance may counteract the protective effects of another substance, leading to an increased risk of cancer. For example, alcohol consumption may antagonize the protective effects of a healthy diet against liver cancer.
3. Potentiation: One substance may enhance the carcinogenic effects of another substance. For example, smoking can potentiate the carcinogenic effects of exposure to certain chemicals in tobacco smoke.
4. Multistage carcinogenesis: Cocarcinogens can contribute to the development of cancer through multiple stages of carcinogenesis, including initiation, promotion, and progression.
Understanding cocarcinogenesis is important for developing effective cancer prevention strategies and for identifying potential co-carcinogens in our environment and diet. By identifying and avoiding co-carcinogens, we can reduce our risk of cancer and improve our overall health.
Some common types of lung diseases include:
1. Asthma: A chronic condition characterized by inflammation and narrowing of the airways, leading to wheezing, coughing, and shortness of breath.
2. Chronic Obstructive Pulmonary Disease (COPD): A progressive condition that causes chronic inflammation and damage to the airways and lungs, making it difficult to breathe.
3. Pneumonia: An infection of the lungs that can be caused by bacteria, viruses, or fungi, leading to fever, chills, coughing, and difficulty breathing.
4. Bronchiectasis: A condition where the airways are damaged and widened, leading to chronic infections and inflammation.
5. Pulmonary Fibrosis: A condition where the lungs become scarred and stiff, making it difficult to breathe.
6. Lung Cancer: A malignant tumor that develops in the lungs, often caused by smoking or exposure to carcinogens.
7. Cystic Fibrosis: A genetic disorder that affects the respiratory and digestive systems, leading to chronic infections and inflammation in the lungs.
8. Tuberculosis (TB): An infectious disease caused by Mycobacterium Tuberculosis, which primarily affects the lungs but can also affect other parts of the body.
9. Pulmonary Embolism: A blockage in one of the arteries in the lungs, often caused by a blood clot that has traveled from another part of the body.
10. Sarcoidosis: An inflammatory disease that affects various organs in the body, including the lungs, leading to the formation of granulomas and scarring.
These are just a few examples of conditions that can affect the lungs and respiratory system. It's important to note that many of these conditions can be treated with medication, therapy, or surgery, but early detection is key to successful treatment outcomes.

- Asbestos is the name used to group a class of naturally occurring mineral fibers that have been widely used for industrial processes and products and is associated with adverse effects on human health. (cdc.gov)
- Asbestos fibers have industrial and commercial applications because of their strength, flexibility and electrical and heat resistant properties. (cdc.gov)
- When the mineral fibers are handled, they can be released into the air and be inhaled, because of their microscopic size and fibrous nature, which can lead to asbestos accumulating in the lungs and causing respiratory illness. (cdc.gov)
- NIOSH intends to pursue partnerships with other federal agencies and stakeholders to help focus the scope of the research that can contribute to the scientific understanding of asbestos and other mineral fibers, to fund and conduct the research activities, and to develop and disseminate educational materials describing results from the mineral fiber research and their implications for occupational and public health policies and practices. (cdc.gov)
- Asbestos minerals have separable long fibers that are strong and flexible enough to be spun and woven and are heat resistant. (cdc.gov)
- Asbestos fibers can enter the air or water from the breakdown of natural deposits and manufactured asbestos products. (cdc.gov)
- Asbestos fibers do not evaporate into air or dissolve in water. (cdc.gov)
- Asbestos fibers are not able to move through soil. (cdc.gov)
- Asbestos fibers are generally not broken down to other compounds and will remain virtually unchanged over long periods. (cdc.gov)
- Asbestos fibers may be released into the air by the disturbance of asbestos-containing material during product use, demolition work, building or home maintenance, repair, and remodeling. (cdc.gov)
- In general, exposure may occur only when the asbestos-containing material is disturbed in some way to release particles and fibers into the air. (cdc.gov)
- Breathing high levels of asbestos fibers for a long time may result in scar-like tissue in the lungs and in the pleural membrane (lining) that surrounds the lung. (cdc.gov)
- Asbestos is the name of a group of minerals with long, thin fibers. (medlineplus.gov)
- Asbestos fibers are so small you can't see them. (medlineplus.gov)
- If you disturb asbestos, the fibers can float in the air. (medlineplus.gov)
- If you breathe in high levels of asbestos over a long period of time, the fibers can build up in the lungs. (medlineplus.gov)
- Drinking water may contain asbestos from natural sources or from Asbestos fibers can enter the air or water from the breakdown of asbestos-containing cement pipes. (cdc.gov)
- Breathing high levels of asbestos fibers for a long time more quickly. (cdc.gov)

(cdc.gov)
- While many advances were made in the scientific understanding of occupational health effects from asbestos and other mineral fibers in the mid- and late-20th Century, many questions and areas of scientific uncertainty remain. (cdc.gov)
- Uncertainty is never desirable when human health is at issue," said NIOSH Director John Howard, M.D. "By posting the draft roadmap for scientific research, we seek to stimulate a public dialogue that will define the pressing scientific questions about asbestos and other mineral fibers, identify new scientific advancements that may be brought to bear on those questions, and lay out the research most likely to bring certainty out of uncertainty. (cdc.gov)
- The draft roadmap reflects NIOSH's continuing leadership in research and recommendations to prevent illness and death from occupational exposures to asbestos and other mineral fibers. (cdc.gov)
- Exposure to asbestos occurs through inhalation of fibers in air in the working environment, ambient air in the vicinity of factories handling asbestos, or indoor air in housing and buildings containing asbestos materials. (medscape.com)
- Knowledge of asbestos-related diseases accumulated for over 100 years as the industrial value of asbestos became recognized for the strength of its fibers and their resistance to destruction, resulting in increasing production and use until multiple health effects became apparent. (medscape.com)
- Prolonged exposure and inhalation of asbestos fibers can cause cancer and asbestosis, a serious respiratory disease. (epa.gov)

- Asbestos can cause significant and irreversible risks-including cancer, mesothelioma and other diseases-to those who come into direct contact with friable and airborne asbestos fibers. (aia.org)
- This is especially concerning for contractors, builders, architects and homeowners who could be exposed to dislodged asbestos fibers during the demolition and building process if they are unaware of its presence. (aia.org)
- However, its potential to cause malignancy at other sites that may also receive a substantial dose of asbestos fibers has not been as extensively investigated. (nih.gov)
- microscopic asbestos fibers, when inhaled, can cause certain types of often fatal lung disease, making asbestos hazard awareness an essential training topic. (hsi.com)
- Airborne asbestos represents a health risk because the unseen fibers can be inhaled unknowingly. (hsi.com)
- The asbestos fibers breathed in by workers can cause serious diseases of the lungs and other organs that may not appear until years after the exposure has occurred. (hsi.com)
