Atlantic Ecology Division, US Environmental Protection Agency, Narragansett, RI 02882, USA
Mar Pollut Bull 44:286-93. 2002..However, interpretation of these results may be skewed because only a small number of interstitial water (n = 13) and whole sediment (n = 5) TIEs have been completed. These trends may change as more data are collected...
