Conclusion
Quantitative results of PPCPs were obtained using HPLC-Orbitrap MS.
Semi-quantitative results showed the presence of surfactants, musks and treatment by-
products in biosolids.
Efforts to obtain analytical standards to complete the studies are on-going.

Quantitative Determination of PPCPs in Biosolids Samples
Quantitative determination of targeted PPCPs in biosolids are shown in Table 3. Five
compounds, i.e., bisphenol A, caffeine, CBZ, TCC and TCS, were found in all six samples
at the high ppb range.
Table 4 showed targeted screening results from the same samples with 100%
occurrence. These include known treatment by-products of CBZ, TCC and TCS, artificial
sweeteners, surfactants, musks were abundant along with organphosphorus flame
retardant and quaternary ammonium surfactants.
