Determination of Uptake Kinetics (Sampling Rates) by Lipid-Containing Semipermeable Membrane Devices (SPMDs) for Polycyclic Aromatic Hydrocarbons in water.Entry ID: usgsbrdcerc_samplingrates
Abstract: The use of lipid-containing semipermeable membrane devices (SPMDs) is becoming
commonplace, but very little sampling rate data is available for the estimation
of ambient contaminant concentrations from analyte levels in exposed SPMDs.
The investigators determined the aqueuous sampling rates (RsubsS; expressed as
effective volumes of water extracted daily) of the standard (commercially
available ... design) 1-g triolein SPMD for 15 of the priority pollutant (PP)
polycyclic aromatic hydrocarbons (PAHs) at multiple temperatures and
concentrations. Under the experimental conditions of this study,
recovery-corrected RS values for PP PAHs ranged from approximately 1.0 to 8.0
L/d. These values would be expected to be influenced by significant changes
(relative to this study) in water temperature, degree of biofouling, and
current velocity-turbulence. Included in this paper is a discussion of the
effects of temperature and octanol-water partition (Kow); the impacts of
biofouling and hydrodynamics are reported separately. Overall, SPMDs responded
proportionately to aqueous PAH concentrations; i.e., SPMD RS values and
SPMD-water concentration factors were independent of aqueuous concentrations.
Temperature effects (10, 18, and 26 degrees Centigrade on Rs values appeared to
be complex but were relatively small.
Sampling rates were studied in order to estimate ambient contaminant
concentrations from analyte levels in exposed SPMDs.

Quality About 25% of each sample set consisted of QC samples, that is, process blanks,
controls, spikes, etc. Spiked samples used in flow-through diluter studies
were generated by fortifying diluter control SPMDs and water with approximately
200 ng of each PP PAH. The percent recoveries of the PP PAH residues from
spiked SPMD ... controls ranged from 21 (naphthalene) to 109% (fluorene) with
coefficients of variation generally < 20%. For static freshwater exposures,
spiked samples consisted of control water and control SPMD lipid and membrane
fortified separately with 900 ng of each PAH. In general, the recovery of PP
PAHs from spiked SPMDs, throughout the analytical procedures, remained constant
at ~~60% with good precision. Higher recoveries of PAHs (80 and 90%) were
observed for fortified SPMD membrane and lipid, respectively, from static
freshwater exposures. For each batch of SPMD samples (n = 12) from the diluter
and static freshwater studies, an SPMD blank (a freshly prepared SPMD) and a
reagent blank (75 mL of hexane) were also taken through the entire enrichment
