As PAHs are both ubiquitous and occur as complex mixtures at many National Priority List sites, these compounds are of interest for post-disaster exposures.<h4>Objective</h4>This study tests the field application of the KinExA Inline Biosensor in Galveston Bay and the Houston Ship Channel (GB/HSC) and in the Elizabeth River, characterizing the PAH profiles of these region's soils and sediments. To our knowledge, this is the first application of the biosensor to include soils.<h4>Methods</h4>The biosensor enables calculation of total free PAHs in porEnvironmental researchBiosensor applications in contaminated estuaries: Implications for disaster research response.PMC8639622R01 ES024245P42 ES027704T32 ES026568P30 ES029067Unger MAHorney JAKnap AHMcDonald TJCamargo KDellapenna TMSericano JLWade TLVogelbein MAChiu WAfalseBiosensor applications in contaminated estuaries: Implications for disaster research response.<h4>Background</h4>Given the time and monetary costs associated with traditional analytical chemistry, there remains a need to rapidly characterize environmental samples for priority analysis, especially within disaster research response (DR2).
