ABSTRACT
Sediment sampling has been an increasing field of interest to the environmental community, especially the measurement of pore-water for bio-availability studies. Various techniques are available for sampling sediment. Typically these methods involve removal and transfer of sediment and/or pore-water to containers for shipment to an outside laboratory for analysis. Passive sampling, however, can be performed to allow for in-situ sample collection without the need to for physical removal or transfer of the sediment or pore-water. In-situ passive sampling minimizes sample handling and potential for loss of volatile compounds of concern. The process is simple, cost effective, and provides semi-quantitative and/or quantitative measurement of compounds of concern. This paper describes the use of a membrane based passive sampler to quantify VOCs and SVOCs in pore-water.
