In the United States, the EPA EMAP-Estuaries Program and the NOAA Bioeffect
s Surveys provide large data sets with which to test proposed relationships
between sediment chemistry and toxicity. The conclusion is that no chemica
l measurement reliably predicts sediment toxicity. These findings challenge
the use of chemical data to imply biological hazard and the way toxicity d
ata are used in sediment management. Published by Elsevier Science Ltd.
