Abstract
A method for the analysis of biological tissues for 104 PPCP compounds has been
developed and validated. The method is based on EPA Method 1694A but also includes
the additional 32 compounds that are being added in an upcoming revision of this method
(Method 1694B). The tissue method incorporates all aspects of the LC/MS/MS analysis,
quantification and QA/QC but the extraction has been modified to accommodate the
tissue matrix. In this presentation we will discuss various extraction and extract cleanup
options that were investigated, the effects of extraction solvent and sample size. Method
performance data for the finalized method will be presented along with typical data for
the analysis of fish and mussel samples.
