Biological effects on viviparous blenny exposed to chrysene and held in synthetic as well as in natural brackish water

Viviparous blenny (Zoarces viviparous) were exposed to chrysene and held in natural brackish water as well as in two different synthetic brackish waters, all with a salinity of 6.8%. After 10 weeks of exposure a number of different biomarkers was analysed. The result indicated increased ethoxyresorufin-O-deethylase activity and the formation of two different DNA adduct spots in the liver tissue, as a result of the chrysene exposure. Very similar results of the chrysene exposure were obtained in blenny held in the two synthetic brackish waters. No influence of the synthetically made waters compared to the natural brackish water could be observed on the biomarkers investigated in the study.
