Title PERC Exposure Risks Due to Vapor Intrusion & Other Causes Identified by EMSL Analytical, Inc.
Introduction EMSL Analytical provides testing services to identify the presence of tetrachloroethylene (PERC) from indoor air quality and environmental samples.

Cinnaminson, NJ, April 10th, 2015

Tetrachloroethylene, also commonly referred to as PERC, is a manufactured colorless liquid chemical that has been used widely for dry cleaning, as a chemical intermediate, metal degreaser and as a component of some consumer products.  Exposure to PERC can occur in some home and work environments due to the use of the chemical or from air, water, groundwater and soils that have become contaminated.

People can even be exposed to PERC through a process known as vapor intrusion.  This occurs when a home or building is constructed over contaminated soils or groundwater and the chemical migrates into the structure through cracks and openings in the structure’s foundation.

The Department of Health and Human Services (DHHS) has determined that tetrachloroethylene may reasonably be anticipated to be a carcinogen and the International Agency for Research on Cancer has classified it as a Group 2A carcinogen.  The Agency for Toxic Substances & Disease Registry (ATSDR) reports that tetrachloroethylene has been found in at least 771 of the 1,430 National Priorities List (NPL) sites identified by the Environmental Protection Agency (EPA).

“Exposure to PERC typically occurs by breathing contaminated air or drinking polluted water,” said Joe Frasca, Senior Vice President of Marketing at EMSL Analytical, Inc., one of the nation’s leading PERC testing laboratories. “Once in the body, it can remain stored in fat tissue. The EPA reports that even breathing PERC for short periods of time can adversely affect the human nervous system and that breathing it over longer periods of time has been shown to cause liver and kidney damage in humans.”

For those concerned about potential exposure to PERC due to vapor intrusion, occupational exposure risks or other routes, EMSL provides sampling supplies and testing solutions.  EMSL also recently sponsored an educational video about PERC and exposure concerns that can be seen at: http://youtu.be/f2Mac3bRfE8.
