Abstract
  • The Port of Trapani is actually investigated as a model case-study for the application of an integrated, multidisciplinary Weight Of Evidence (WOE) approach to improve criteria of quality characterization, dredging and management options for harbour sediments. The WOE is based on the evaluation of multiple Lines of Evidence (LOEs) including chemical, physical and biological investigations carried out on approximately 300 samples obtained from 100 cores up to 10 m long. Among biological effects, particular importance is given to criteria for defining the ecotoxicological hazard. A battery of bioassays will be applied, including the marine bacteria Vibrio fischeri (on bulk sediment), the sea urchin Paracentrotus lividus and the alga Phaedactylum tricornutum (on freshly extracted or frozen elutriate). The results will be elaborated according to a recently developed model which, based on logical flow-charts and mathematical algorithms, give different weights according to biological end-points and magnitude of responses, providing a synthetic index of hazard among one of five possible classes [1]. The integration of ecotoxicological results with those from chemical characterization (also elaborated within a specific module) will represent the first level of an Ecological Risk Assessment (ERA) procedure, according to the actual legislation and guidelines on harbour dredging and sediment management set by ISPRA [2]. The analysis of benthic communities (with particular focus on the study of marine seagrasses), microbiology and the development of some new biomarkers on P. lividus, will represent additional LOEs toward a second level of a detailed procedure to achieve a more comprehensive ecological risk analysis associated to polluted sediments. In both levels of data elaboration, the previously developed conceptual and software-assisted model will be continuously validated and adapted for handling the critical issues of sediment characterization and management in harbors areas, also providing scientifically sound and tested hypotheses to revise actual normative guidelines. The model will aim to elaborate results from various lines of evidence, aggregate results into specific synthetic indices of hazard, and provide an integrated index of ecological risk, useful for environmental decisors and stakeholders.
