Loss of weight and appetite Crackling sound when breathing The stiffening of the lungs causes the coughing, discomfort and crackling sound associated with asbestosis, and it also results in less oxygen being delivered to the blood, causing shortness of breath. Because the body relies on oxygen for energy, chronic breathing difficulties lead to fatigue and weight loss.
All six types of asbestos minerals have common characteristics. All forms of the mineral are odorless and tasteless. When asbestos is present in a material or product, it cannot be detected by a visual examination and must be tested in a laboratory.
These properties often make it difficult to determine specific risks of asbestos exposure. However, any exposure to the group of minerals can lead to pleural mesothelioma and other diseases such as lung cancer or asbestosis. It is important for individuals to know their risks, especially if they have a history of asbestos exposure.
People who have had exposure should learn how to protect themselves through medical monitoring. Types of Asbestos Causing Pleural Mesothelioma In addition to the properties shared by all asbestos minerals, each of the six types has its own distinct features.
The types are separated into categories based on the physical appearance of individual asbestos fibers. Asbestos minerals are divided into two categories: Serpentine asbestos and amphibole asbestos. Serpentine Asbestos Serpentine asbestos refers to asbestos made up of long, curly fibers.
This category only includes one mineral, called chrysotile, also known as white asbestos. It was the most commercially used form of asbestos. Its flexible nature easily allowed it to be used in products and combined with other elements.
Prior to widespread knowledge of pleural mesothelioma and its connection to asbestos, the mineral was hailed for its fireproof and heat-resistant qualities. It was used throughout the U. Amphibole Asbestos Amphibole asbestos includes the other five asbestos minerals: Amosite, crocidolite also called blue asbestostremolite, actinolite and anthophyllite.
These minerals are composed of brittle, rod- or needle-shaped fibers. Because of these properties, amphibole fibers are more hazardous than chrysotile when inhaled or ingested.
However, the same characteristics usually make it a bad candidate for use in commercial products. Exposure to amphibole asbestos is mostly limited to exposure to naturally occurring deposits. Pleural Mesothelioma and Potential Causes of Asbestos Exposure Asbestos exposure can cause a number of health problems.
The most dangerous is pleural mesothelioma, also known as malignant pleural mesothelioma. This cancer is typically caused by one of three types of exposure to asbestos: Occupational exposure, secondary exposure or environmental exposure.
Occupational Asbestos Exposure Occupational asbestos exposure refers to coming into contact with asbestos while on the job.
Occupational exposure, the most common cause of pleural mesothelioma, generally happens with blue-collar jobs, and most examples came prior to the s. Individuals were most likely to suffer from asbestos exposure if they worked in construction, shipyardspower plants or other hazardous work environments.
Secondary Asbestos Exposure Secondary asbestos exposure includes occurrences among family members of asbestos workers. Men who worked with asbestos brought fibers home on their dirty clothes each night. Then wives or other family members shook out the clothing to get rid of asbestos-laden dust, unknowingly exposing themselves and others to the deadly substance.
Environmental Asbestos Exposure Environmental asbestos exposure is any indirect exposure, caused either by environmental pollution or by naturally occurring asbestos. Naturally occurring asbestos deposits have been found throughout the country, particularly in parts of California and Montana.As asbestos-related cancers became better recognized in the second half of the 20th century, measures were taken to reduce exposure, including establishing exposure standards and laws that banned the use of asbestos in construction materials.
Asbestos poisoning can occur when asbestos fibres are inhaled or ingested. The effects of asbestos poisoning (asbestosis, mesothelioma, lung cancer etc) can take as long as forty years to occur. Asbestos exposure is dangerous to your health because when asbestos fibers are inhaled, they can cause lung diseases, lung cancer, mesothelioma, and other cancers.
The most common symptoms of lung disease caused by asbestos are shortness of breath and cough. EPA is proposing a significant new use rule (SNUR) for certain uses of asbestos. Learn more. EPA also released for public comment the asbestos problem formulation .
Asbestosis is a type of pulmonary fibrosis, a condition in which the lung tissue becomes scarred over time. It is not a type of cancer, but asbestosis has the same cause as mesothelioma and other asbestos-related.
Most cases trace back to consistent exposure to asbestos-containing materials in construction sites, ships and industrial facilities.
Exposure to asbestos increases your risk of developing lung disease. That risk is made worse by smoking. In general, the greater the exposure to asbestos, the .
