In-Planta Sampling for Site Characterization

Abstract

Sampling of plant tissues has great benefits and poses unique challenges. Recently tree-core analysis has provided a rapid, semi-quantitative delineation of VOC-contaminated soil and groundwater with minimal cost and impact to property. Sampling plant matrices can be difficult given variable volatility of compounds and the difficulty in quantifying low levels in plant tissues as headspace sampling can be mass limited. using SPME, in-planta sampling can be accomplished with much lower detection levels as mass-limitations are essentially non-existent as the entire tree is the sample size. Issues that had to be evaluated and overcome include the potential for equilibrium sampling using a PDMS fiber SPME or the need for using time-weighted average (TWA) sampling techniques that had not been tested for the highly volatile chlorinated solvents tested in this approach. overall method detection limits are reduced by several fold and metabolic products detected give evidence of natural attenuation or remedial efficacy.
