In Planta Passive Sampling Devices for Assessing Subsurface Chlorinated Solvents

Abstract

Contaminant Concentrations in Trees Have Been Used to Delineate Groundwater Contaminant Plumes (I.e., Phytoscreening); However, Variability in Tree Composition Hinders Accurate Measurement of Contaminant Concentrations in Planta, Particularly for Long-Term Monitoring. This Study Investigated in Planta Passive Sampling Devices (PSDs), Termed Solid Phase Samplers (SPSs) to Be Used as a Surrogate Tree Core. Characteristics Studied for Five Materials Included Material-Air Partitioning Coefficients (Kma) for Chlorinated Solvents, Sampler Equilibration Time and Field Suitability. the Materials Investigated Were Polydimethylsiloxane (PDMS), Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), Polyoxymethylene (POM) and Plasticized Polyvinyl Chloride (PVC). Both PDMS and LLDPE Samplers Demonstrated High Partitioning Coefficients and Diffusivities and Were Further Tested in Greenhouse Experiments and Field Trials. While Most of the Materials Could Be Used for Passive Sampling, the PDMS SPSs Performed Best as an in Planta Sampler. Such a Sampler Was Able to Accurately Measure Trichloroethylene (TCE) and Tetrachloroethylene (PCE) Concentrations While Simultaneously Incorporating Simple Operation and Minimal Impact to the Surrounding Property and Environment. © 2013 Elsevier Ltd.
