Biological Effects on Viviparous Blenny Exposed to Chrysene and Held in Synthetic as well as in Natural Brackish Water

摘要

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 6.8/100. After 10 weeks of exposure a number of different bio- markers was analysed. The result indicated increased ethoxyresorufin-O-deethy- lase 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 tow synthetic brackish waters.
