First eco-toxicological survey in the Miramare Marine Reserve (Gulf of Trieste, Italy)

This study is a survey aiming at applying and evaluate different analysis methodologies in the Miramare Marine Reserve, rather than being the result of an analysis campaign. Marine bacteria, rotifers, marine and fresh water crustaceans and fresh water algae were used as ecotoxicological tests. Biomarkers in decapod crustaceans and the assessment of chemical analysis in mussel tissues were used, respectively, as biosensors and bioaccumulators. Acute toxicity signals and not negligible PAHs levels in mussels were detected in the small port of Grignano area, and freshwater inputs in this area provide signals of eutrophic conditions. The acute toxicity level is not high, but it certainly requires an enhancement of the monitoring activities.
