Abstract:

This 1-year SEED project advanced the field of passive sampling on two major fronts 1 Developed an engineering approach to extend in-situ passive sampling to high molecular weight compounds in sediment porewater, and 2 Explored an equilibrium passive sampling approach for MeHg in sediment porewater. Both proof-of-concept developments are novel and were successful in paving the way for further research to operationalize the extension of passive sampling to these heretofore difficult to measure analytes in sediment porewater.
