Itsas ingurumenerako mikrokutsatzaile organiko hidrofobikoen presentzia eta eraginak aztertzeko estrategien taxutzea

Abstract

The efects of hydrophobic microcontaminants such as alkylphenols, organophosphorus compounds, organochloride pesticides, phthalates and musk fragances were studied in mussels. The proposed analytical strategy is based on the combination of passive sampling studies, bioconcentration measurements of micropollutants in mussels, environmental NMR metabolomics of two tissues (gonad, muscle) and hemolymph of mussels and histological analysis. By means of this work, it was verified the feasibility of this strategy in controlled conditions with intent to use it in future environmental studies. The micropollutants mixture was responsible of early spawning in mussels. In fact, the most significant metabolic changes were observed in the same day that spawning took place.
