PRLog - Nov. 29, 2010 - PEORIA, Ariz. -- PCBs belong to a broad family of man-made organic chemicals known as chlorinated hydrocarbons. They were domestically manufactured from 1929 until their ban in 1979. According to the U.S. Environmental Protection Agency’s (EPA) website, “Due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties, PCBs were used in hundreds of industrial and commercial applications including electrical, heat transfer, and hydraulic equipment; as plasticizers in paints, plastics, and rubber products; in pigments, dyes, and carbonless copy paper; and many other industrial applications.”
Although no longer commercially produced in the United States, PCBs may still be present in products and materials produced before the 1979 ban. Last year the EPA released new guidance regarding PCBs in caulk from buildings constructed or renovated between 1950 and 1978. The EPA recommends testing for PCBs in peeling, brittle, cracking or deteriorating caulk in buildings, especially in school environments.
Due to their chemical structure, PCBs do not readily break down and therefore may remain for long periods of time cycling between air, water and soil. PCBs have been demonstrated to cause a variety of adverse health effects on the immune, reproductive, nervous and endocrine systems.
Clark Seif Clark, a leading provider of environmental and indoor air quality (IAQ) consulting services, has broad expertise in dealing with PCBs in indoor environments. “Decades after their ban PCBs are still a potential health hazard,” reported Derrick A. Denis, V.P. Indoor Environmental Quality at CSC. “Testing for their presence in older structures will determine if there is an exposure risk to building occupants.”
