Notes Meets Key Objectives Requires More Time to Derive Result than Acute Exposure Duration of Concern; Time-Integrated Measurement Requires More Time to Derive Result than Acute Exposure Duration of Concern; Time-Integrated Measurement Requires More Time to Derive Result than Acute Exposure Duration of Concern; Time-Integrated Measurement Requires More Time to Derive Result than Acute Exposure Duration of Concern; Time-Integrated Measurement Need to be Careful of Preferential Pathways, Natural Pressure Dynamics, and Employ Chemical Monitoring Requires Expertise to Operate; Can be Unstable when Temperature Changes; Only a Single Point in Time/Space Measurement Not Typically Sufficiently Sensitive for Indoors; Unstable when Temperature Changes; Only a Single Point in Time/Space Measurement Not Typically Sufficiently Sensitive for Indoors; Unstable when Temperature Changes; Only a Single Point in Time/Space Measurement Need to Operate in Continuous Monitoring Mode to Meet Additional Objectives Requires Expertise to Operate; Only a Single point in Time/Space Measurement Need to be Careful of Preferential Pathways and Natural Pressure Dynamics Can be used to Augment other Options;Not Always Sufficient as Stand-Alone
