Mesothelioma and Environmental Asbestos Concerns

February 2, 2011

Asbestos, a naturally occurring mineral that was incorporated into more than 5,000 products, was largely utilized before the 1980s for its insulating and fireproofing characteristics. This toxic mineral can be found in various deposits throughout the world and the environmental hazard surrounding asbestos still exists today. Some countries even continue mining and exporting asbestos to developing regions. Careers that have felt the largest impact from mesothelioma cancer, an asbestos-related disease, include those in the construction, manufacturing and shipyard industries.

One of the biggest concerns for a construction worker is working at a site where asbestos-containing materials are present. Without proper testing, the presence of asbestos can remain completely unknown. If asbestos is detected within the area, minimizing dust should be a main priority and specialists should be hired. Another concern is naturally occurring asbestos that is in the soil. Places where naturally occurring asbestos has been known to exist include baseball fields, school playgrounds and dirt roads among areas known to contain asbestos in the soil.

Mesothelioma is a rare form of cancer almost exclusively caused by asbestos exposure. The most common form of the cancer is pleural mesothelioma, which develops in the lining of the lungs. Due to a severe latency period of symptoms ranging between 20 and 50 years from the time of exposure, mesothelioma cancer is often diagnosed in a late stage of development.

This tendency for late diagnosis often complicates mesothelioma treatment options and as a result the average mesothelioma life expectancy is four to 18 months. There is no cure for this cancer, but some patients who were diagnosed early enough have survived mesothelioma. For this reason, it is important for anyone exposed to asbestos to seek regular medical exams to check for signs of asbestos disease. In some cases, patients may file a mesothelioma lawsuit to obtain financial assistance for their pursuit of medical care.

The US EPA Microbiological and Chemical Exposure Assessment Research Division (MCEARD)

February 1, 2011

The Microbiological and Chemical Exposure Assessment Research Division (MCEARD) is a division of the National Exposure Research Laboratory (NERL) and operates within the Office of Research and Development (ORD).

MCEARD conducts research to measure, characterize and predict the exposure of humans to chemical and microbial hazards. This research provides information on environmental pathways which contaminants of public health concern are transported to populations at risk. Analytical quantitative methods are developed to accurately and specifically measure human risk factors associated with inhalation, ingestion and dermal pathways. Surveys and monitoring studies are carried out to determine the levels of hazardous chemicals and microbials in environmental matrices, and human populations are studied to determine significant exposure pathways, the levels of exposure and the sources of exposure factors. State-of-the-art analytical methods are used to measure organic and inorganic chemicals. Genomic and immuno-based methods, as well traditional cultural methods, are used to measure hazardous bacteria, viruses, fungi and protozoa. Molecular- and sero-epidemiological tools are used to assess human populations for evidence of exposure to environmental hazards.

The Division conducts its multidiscipline research program with a broad skill mix of scientists that includes organic, inorganic and analytical chemists, bacteriologists, virologists, parasitologists, immunologists and molecular biologists. The Division is one of several U.S. EPA research organizations located in the Andrew W. Breidenbach Environmental Research Center at 26 West M.L. King Drive, Cincinnati, Ohio, 45268 . This Center is in the Clifton/Corryville area just north of downtown Cincinnati and is located between interstates I-75 and I-71. It is situated adjacent to the main campus of the University of Cincinnati. The Division consists of three branches, the Biohazard Assessment Research Branch, the Microbial Exposure Research Branch and the Chemical Exposure Research Branch.
