suitable invertebrate test species, with Enchytraeus crypticus as a potential second candidate, the

latter particularly suitable for dredged materials with low organic matter contents. Of these four

species C. esculentus and E. fetida have been previously used as test species at the Environmental

Laboratory. Test protocols were further developed and streamlined, and collected data of several

fact-finding experiments evaluated. The experience will be used to perform and evaluate exposure-

based effects assessments of contaminants in terrestrial plants and animals, and to develop guidance

to standardize the interpretation of test results in risk assessment aimed at determining effective

long-term management strategies for CDFs.

ACKNOWLEDGMENT: The help of Mr. R. A. Price with the initial field survey is gratefully

acknowledged.
