Keywords: environmental pollutants marine vertebrates biomarkers endocrine disruptors

The presence of environmental can lead to toxic effects in exposed species. Among these, the effects on endocrine system pose a certain concern as they can deeply alter reproductive capacity and fitness of organisms. The evaluation of contaminants levels and of markers of endocrine disruption in marine and fresh water species allows the assessment of potential exposure and of the alteration induced.

1. Evaluation of alterations induced by organic environmental pollutants and by heavy metals on endocrine balance of fresh water and marine fish species, by quantifying exposure markers and hormonal levels, focusing on thyroid hormones, following experimental exposure to contaminants themselves.

2. Quatificatin of contaminants in large marine vertebrates (cetaceans and sea turtles) and on the evaluation of the impact they can have on endocrine balance of studied species, focusing on tissue and plasmatic thyroid hormones levels and on reproductive imbalance markers, like VTG in sea turtles.

3. Monitoring of environemtnal polutants in fresh water and marine fish species. Both species of commercial or ecological interest will be considered. When commercial species are considered, a risk assessment for human will also be performed.
