Abstract: The objective of this study was to investigate the pattern of enzymatic activities, environmental genotoxicity and cytotoxicity in flounder, Platichthys flesus, from the Polish coastal area of the Baltic Sea. Fish were sampled in different contaminated sites in the Gulf of Gdansk and in a reference area outside the gulf. The activities of acetylcholinesterase (AChE), glutathione S: -transferase (GST), catalase (CAT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), were studied, as well as the frequency of micronuclei, nuclear buds and fragmented-apoptotic cells. A higher mean activity level of muscular AChE and a lower activity level of hepatic GST were evident in samples taken from the reference site, relative to those found in the gulf. Modeled CAT activity (in both liver and gill tissue), blood plasma LDH and CK activities were all significantly higher in flounder collected at locations within the Gulf of Gdansk than at the reference site. No statistically significant alterations were observed in the activities of ALT and AST in the blood plasma of flounder in this study. Fish collected from a location at the mouth of the Vistula River showed the highest hepatic GST and CAT, the highest gill CAT activity, and the highest frequency of blood micronuclei, nuclear buds and fragmented-apoptotic cell inductions, as well as the lowest level of blood plasma CK. The present study confirms that compared to fish from the reference area, flounder from the Gulf of Gdansk clearly demonstrate a different enzyme activity, genotoxicity and cytotoxicity biomarker response pattern.
