Figure 3From: Determining the chemical activity of hydrophobic organic compounds in soil using polymer coated vialsAmounts of analyte PAH (nPAH) plotted as a function of volume of PDMS (VPDMS) in nine coated vials after equilibration with the test soil (in slurry) for five days. Three representative compounds were selected for having the highest, median and lowest r2-values.Back to article page
