PHARMACEUTICAL RESIDUES DETECTED IN FISH RIVERS
ICRA RESEARCHERS DETECTED FOR THE FIRST TIME AFTER AN EXHAUSTIVE FIELD STUDY IN SPAIN AND PIONEER IN EUROPE, RESIDUES OF PHARMACEUTICAL IN FISHES OF EBRO, LLOBREGAT, JÚCAR AND GUADALQUIVIR RIVERS.
These studies are presented in Valencia on 26 and 27 November 2012 at the III Annual Conference of the project CONSOLIDER-INGENIO (SCARCE), a multidisciplinary project coordinated by Damià Barceló, director of the ICRA.
The work, which had been tested in the laboratory, is the result of ICRA researchers Belinda Huerta (Predoctoral Student and study leader), Anna Jakimska (Predoctoral Student, University of Technology, Gdansk, Poland, and visitor of ICRA), Meritxell Gros (Postdoctoral Researcher actually at the CSIRO Land and Water, Adelaide, Australia), Sara Rodriguez Mozaz (Research Scientist) and Damia Barcelo (director ICRA) -from left to right at the photo.
In different species of fish have been detected Diclofenac and states that this contaminant is found in all watersheds. The European Union wants to add it to the list of priority pollutants in water samples in control.
Damià Barceló explains, that these drug accumulation in fish are not bad for human health. The long-term risks are for aquatic systems.
This study shows that wastewater treatment plants of the four studied basins (Ebro, Llobregat, Júcar and Guadalquivir) does not eliminate diclofenac. Also that fish from the river are able to accumulate it, "indicating thus a continuing risk of exposure to the drug, whose effects at long term in aquatic ecosystem of the 4 rivers are difficult to predict, but the negative impact will be done".
