Surface In-Situ Networks
The perfluorocarbon tracer compounds (PFTs) are totally fluorinated cycloalkane compounds that make good tracers because of their physical characteristics and because they are present in the atmosphere at low levels. BNL Tracer Technology Group analysis methods can detect background (parts per quadrillion, 10e15) levels of most PFTs in 1.5 L air samples. Multiple compounds can be resolved in a single analysis. PTFs have been used since the early 1980s to study atmospheric transport and dispersion on local, regional, and continental scales. These studies have led to increased understanding of the movement of pollutants and other hazardous substances in the atmosphere and to improvement and validation of atmospheric transport models. These research programs have application to issues of critical national and global importance such as homeland security, air quality, and climate change. The Brookhaven National Laboratory Tracer Technology Group has developed methods to release and detect PFTs. These methods have been used in atmospheric transport and dispersion on local, regional, and continental scales; in building infiltration research in homes commercial buildings, and nuclear power plant control rooms; and to find leaks in underground utility lines and hazardous waste storage systems.
