"Beryllium Particulates and Their Detection" Symposium Announced
Eichrom is pleased to co-sponsor The Second Symposium on Beryllium Particulates and Their Detection November 8 & 9, 2005 at the University Park Marriott in Salt Lake City, UT. Chronic Beryllium Disease (CBD) has been identified in over 100 current and former U.S. Department of Energy workers. Because of the seriousness of CBD, the U. S. DOE promulgated in 1999 the CBD prevention program, 10CFR Part 850, to protect DOE workers from exposure to Be contaminated dust. This program requires frequent monitoring of air and possibly contaminated surfaces to identify potential health risks. Cases of CBD are not confined to only nuclear workers. The industrial hygiene community is reviewing protective measures with an eye toward reducing allowable workplace beryllium levels to decrease future instances of CBD.
At the request of scientists at the Y-12 National Security Complex in Oak Ridge, TN, Eichrom has developed a new method to improve the efficiency of beryllium measurements performed on area surface swipes. The method is compatible with traditional ICP-AES measurements. After surface swipes are digested using standard acids, Eichrom’s Beryllium Resin is used to remove spectrally interfering elements before ICP-AES analysis is performed. This essentially eliminates the need to rerun troublesome samples via ICP-MS. Y-12 has completed their initial testing of this method and presented their findings at the Spring ACS National Meeting in San Diego, CA, March 2005. The data from Eichrom and PGRF research and development leading up to this successful application was also presented at the 2005 ACS meeting and will be published in Talanta and Solvent Extraction and Ion Exchange . Y-12 plans to implement the Beryllium sample preparation using Beryllium Resin during the late summer of 2005 on as many as 50% of their more difficult samples. This should greatly reduce the delay and maintenance cost associated with reruns using ICP-MS.
