An extraction procedure utilizing sonication with acetonitrile and cleanup using aminopropyl and/or C-18 bonded-phase columns was developed to prepare marine sediments and animal tissues for priority organic pollutant analysis. Recoveries from standard reference and interlaboratory comparison sediments and tissue preparations compared favorably to published mean values. The recovery efficiencies of the procedures were determined by spiking marine sediments and a marine animal-tissue homogenate. Mean recoveries of 22 priority organic pollutants from the sediments ranged from 0% to 84% with a median recovery of 71% and an average percent relative standard deviation (% RSD) of 9%. Mean recoveries of 13 priority organic pollutants from the tissue homogenate ranged from 7% to 76% with a median recovery of 64% and an average % RSD of 5%. Effects of sediment type and storage method on the spike recoveries are discussed.
