This report summarizes the procedures for taking experimental data (chlorine gas concentration time histories) and determining model parameters which can be used directly in atmospheric dispersion models to determine the initial rate of deposition (removal by reaction) of chlorine on typical environmental surfaces.
Using science-based chemical threat and hazard analysis, S&T stands ready to assist emergency planning, preparedness, and response efforts.
DHS S&T announced that it will join several New York City agencies for an above- and below-ground air sampling study that will ultimately help urban areas prepare for and recover from incidents involving hazardous materials.
As part of the Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T), the Chemical Security Analysis Center (CSAC) is the nation’s only federal study, analysis and knowledge management center for assessing the threat and hazard(s) associated with an accidental or intentional large-scale chemical event or chemical terrorism event in the United States.
S&T CSAC developed a new cyanide detection test method, both affordable and efficient, to test fire survivors for toxic cyanide exposure at the scene.
S&T’s research and development support prevention and protective strategies, as well as the coordinated surveillance and detection of chemical, biological and explosive threats.

S&T is studying how anhydrous ammonia behaves during a potential leak or spill, whether accidental or intentional, in order to inform planning efforts in communities across the nation.
Crucially important work is accomplished through deploying S&T’s advanced lab-based technical expertise and capabilities in research, development, test and evaluation.
CSAC’s Jack Rabbit project research findings to be published in special edition of the prestigious peer-reviewed Journal of Atmospheric Environment.
