Excerpt from The National Environmental Specimen Bank: Proceedings of the Joint Epa/Nbs Workshop on Recommendations and Conclusions on the National Environmental Specimen Bank, Held at the National Bureau of Standards, Gaithersburg, Maryland, August 19-20, 1976
This banking system was envisioned as having a dual function. First, representative portions of samples included in the bank would be analyzed at the time Of introduction to provide real time monitoring and evaluation of pollutant trends. Evaluation of these trends would serve as early warning sentinels so that proper control measures could be taken to halt rising human body burdens before irreversible damage could occur. Second, a specimen bank would enable the analyst to use tomorrow’s more sensitive and specific methods of chemical analysis on today’s samples. The improved measurement methodology would enable health scientists to determine accurate levels for substances that would be either undetectable or poorly analyzed by today’s less sensitive methodology. The existence of a specimen bank would provide the Opportunity to determine what the body burden of newly recognized toxic substances was in the past and to determine if their levels had changed with time.
