Optimization of Integrative Passive Sampling Approaches for Use in the Epibenthic Environment
Abstract
The overall objective of this research was to develop an integrative passive sampler (IPS) design and protocol that accurately integrates time-weighted concentrations of munitions constituents (MCs) in aquatic systems regardless of the magnitude of flow. Investigations focused on further development of the Polar Organic Chemical Integrative Sampler (POCIS) including modification of sampler design, addition of a performance reference compound (PRC), and development of a microsensor for flow that can be co-deployed. Addition of flow disrupting screen reduced the impact of flow and could be developed pending further research and optimization. PRCs were found to be helpful for some, but not all analytes. Finally, a promising flow sensor was developed. Although all three approaches had relatively positive outcomes, the microsensor for flow had the best opportunities for technology transfer and is suggested for future development.
