Low density polyethylene (LDPE) often is used as the sorbent material in passive sampling devices to estimate the average temporal chemical concentration in water bodies or sediment pore water. To calculate water phase chemical concentrations from LDPE concentrations accurately, it is necessary to know the LDPE-water partition coefficients (KPE-w) of the(More)
The advective flow of sediment pore water is an important parameter for understanding natural geochemical processes within lake, river, wetland, and marine sediments and also for properly designing permeable remedial sediment caps placed over contaminated sediments. Automated heat pulse seepage meters can be used to measure the vertical component of(More)
Chemically enhanced phytoextraction has been proposed as an effective approach to remove metals from contaminated soil through the Italian ryegrass (Lolium multiflorum Lam.). The bioconcentration factor (BCF) and translocation factor (TF) are important determinants for phytoextraction of metals. In microcosm experiments, effects of saponin on the uptake of(More)
