Abstract:
A series of soil, sediment and biosolid samples were extracted by accelerated solvent extraction and analyzed by high-performance liquid chromatography HPLC/MS and HPLC/MS/MS to identify and quantify pharmaceuticals and
personal-care products (PPCPs). In addition, a set of replicate samples and extracts were amended with known amounts of PPCPs at different stages of the extraction to determine PPCP losses within the procedure. Baked Ottawa sand samples were amended with PPCPs and recoveries determined to quantify PPCP recoveries in the absence of naturally-occurring organic matter (NOM). The method recovery studies using NOM-containing and NOM-free sediments suggest that the primary effect of NOM is to sequester PPCPs and shield them from extraction. Staged amendment experiments indicate that the PPCP recoveries subsequent to extraction are not substantially diminished by the presence of NOM matrix components, suggesting incomplete extraction of PPCPs from NOM-containing soils, after equilibration for 24 hours and under extraction conditions previously determined to be optimal. In these samples, overall PPCP concentrations generally are similar in soils and sediments, and substantially greater in biosolids. The distributions of different PPCPs in all three matrix types were comparable and overall concentrations in all three matrixes are higher than in water, including wastewater.
