Spiked sediment and seawater were used to evaluate the recoveries of neutral organic compounds in interstitial water (IW) separated by centrifugation and sampled using a unique aspiration system. An average recovery of 94%±0.8% (SE, n=116) of ten po

As pollution from the Los Angeles County Sanitation Districts (LACSD) outfalls decreased between 1980 and 1983, the macrobenthic community partially recovered and surficial (0–2 cm deep) sediment contamination and toxicity decreased at 60 m water d
