Since the mid-1970s research has focused on the development of sediment toxicity bioassays that could effectively predict potential biological adverse effects and could be used as an effective tool to characterize sediment toxicity. It is widely accepted that there are no chemical measurements that reliably predict sediment toxicity. In addition, sediments are a complex matrix that require complex tests for estimating the actual bioavailability of contaminants (7). Here we review the evaluation process that has been applied in the different initiatives carried out to introduce this new approach in a regulatory context. The design of toxicity tests for the characterization of dredged material in Spain is used as an example.
