Abstract

A set of GC-MS/MS analytical methods was developed to detect and quantify PFCs and PPCPs in five wastewater sludge samples obtained from the Great Lakes Water Authority and in four dry sludge samples after they were HTL treated. Multicollector ICP-MS was used to analyze the heavy metals in the samples. Methylene chloride was used to extract the compounds from sludge samples. For non-GC-able compounds, derivatization was performed before analysis. IBCF was used for derivatizing PPCPs and PFCs. Due to the nature of the samples, the presence of rich organic elements not only complicated the analytical work, but also affected the accuracy of measurements, because of interferences. Nevertheless, a set of PPCPs and PFCs was detected and quantified in the sludge samples in concentrations comparable to those reported in the literature.
