Abstract
    A simple laboratory microcosm system, previously used as a community level sediment bioassay for laboratory contaminated sediments, has been used for testing contaminated field sediments. Meiobenthic communities from the Lynher Estuary were incubated with defaunated sediment collected from the Fal Estuary system where a gradient of heavy metal concentrations is reflected in meiofaunal community structure. In the microcosms changes in nematode community structure were related to sediment metal concentrations. These changes in community structure were similar to those previously observed between creeks in the Fal Estuary system indicating that an experimental microcosm approach can be useful both as a sediment bioassay and in the validation of conclusions drawn from field surveys.
