ABSTRACT

ASTM WK54549 is a new method that determines pesticides, PCB’s and PCB congeners using a Method 625 extraction. This new method will enable laboratories to extract and analyze their semi-volatiles and also run low level pesticides and PCBs without a separate extraction. This poster presents spike and spike duplicate recovery in several complex matrices, method detection limits, and long –term reproducibility of laboratory control samples. Also presented is a technique to qualitatively identify then quantitate aroclors.


Keywords: Wastewater, Gas chromatography/tandem mass spectrometry (GC-MS/MS), PCBs, Organochlorines and Pesticides
