Chemometric approaches have the potential to enhance defense operations against chemical warfare agents (CWAs), for which complex data must be analyzed. Therefore, we have begun an exploration of the use of chemometrics for the correlation of metabolic change with low-level CWA exposure in animal models. In this exploratory study, pigs were exposed to GB (sarin) over a range of concentrations (0.028-0.310 mg/cubic meters) and exposure times (0-180 minutes). Blood (4-8 ...
