Preliminary Evaluation of the Field and Laboratory Emission Cell (FLEC) for Sampling Attribution Signatures from Building Materials
Abstract
This study provides a preliminary evaluation of the Field and Laboratory Emission Cell (FLEC) for its suitability for sampling building materials for toxic compounds and their associated impurities and residues that might remain after a terrorist chemical attack. Chemical warfare (CW) agents and toxic industrial chemicals were represented by a range of test probes that included CW surrogates. The test probes encompassed the acid-base properties, volatilities, and polarities of the expected chemical agents and residual compounds. Results indicated that dissipation of the test probes depended heavily on the underlying material. Near complete dissipation of almost all test probes occurred from galvanized stainless steel within 3.0 hrs, whereas far stronger retention with concomitant slower release was observed for vinyl composition floor tiles. The test probes displayed immediated permanence on Teflon. FLEC sampling was further evaluated by profiling residues remaining after the evaporation of 2-chloroethyl ethyl sulfide, a sulfur mustard simulant. This study lays the groundwork for the eventual goal of applying this sampling approach for collection of forensic attribution signatures that remain after a terrorist chemical attack.
