Practical and scientific difficulties and ethical considerations often prevent experimental pollution studies in the field. Ecotoxicological laboratory experiments are very useful to obtain a first impression on the relative toxicity of a chemical or a chemical waste, or to study the specific mechanisms of action in isolated species. The results of these experiments, however, cannot be easily extrapolated to actual field situations. In ecotoxicology, the need for an experimental basis to assess possible toxicological effects in the field, has led to the use of various experimental systems, which more closely approximate field conditions than can monospecies laboratory-cultures. In this review the progress made along these lines in recent years will be demonstrated. Experiments with two species in one container to introduce competition aspects, and experiments with large model systems representing more or less complete ecosystems in the water column or the benthic environment, will be discussed. An exhaustive list of experimental systems is not given, but various examples illustrate how laboratory and model ecosystem-experiments can be combined to increase OUT insight in to the possible effects of pollutants in the marine environment.
