Linking sediment chemical and biological guidelines for characterization of dredged material.
Dredged material management in Spain and possible options for the different categories is discussed according to chemical sediment quality guidelines. Also an approach using an integrated assessment that includes biological end points as part of a tiered testing schema is discussed for future implementation in Spanish recommendations. To establish the feasibility of using both kinds of guidelines, an example of the utility and validity of the approach that links both chemical and biological guidelines proposed for the management of dredged material characterization processes data from a particular case study associated with a port in the north of Spain are discussed. The use of both kinds of methodologies, together with the necessity of assessing the bioavailability of some contaminants, has been shown as a powerful tool for the best selection of different disposal options of dredged material in the case study described.
