Description

Pharmaceutical and Personal Care Products (PPCPs) are potentially harmful compounds that are present in our water systems. Unfortunately, our Waste Water Treatment Plants (WWTPs) are designed for removal of solid waste rather than small molecules. This leaves low concentrations of PPCPs in our water. Therefore it is necessary to develop a robust method to detect and quantitate PPCPs in the environment. We have developed an LC/MS-MS method and were able to establish limits of quantitation below to 50 parts per trillion (PPT) for acetaminophen, cotinine, trimethoprim, atorvastatin, progesterone, atrazine, lidocaine, and diclofenac. We are going to expand the PPCPs we analyze including trying to detect a wider range of functional groups.
