Abstract
Analytical Methods were developed to determine the concentration of PC DD/PCDF in fish tissue for a national survey conducted by EPA. The met hod was designed to achieve a relatively low cost per sample while mai ntaining adequate quality control. It utilizes a Soxhlet extraction, a cid-celite, florisil and carbon-silica gel chromatography, and HRGC/HR MS analysis. The minimum level of detection for 2,3,7,8-TCDD is approx imately 1 pg/g. Rigorous quality assurance/quality control criteria ha ve been developed to assure the validity of the data.
