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.
