    • Abstract. Environmental mutagenesis was assessed in fish from the selected coastal areas of the Baltic Sea–Kvadofjarden and the Stockholm archipelago (Sweden), the Klaipëda–Bûtingë zone (Lithuania), the Gulf of Gdansk (Poland) and the Wismar Bay (Germany). The frequency of micronuclei, as markers of cytogenetic damage, was evaluated in erythrocytes of 911 flounder (Platichthys flesus), 332 perch (Perca fluviatilis) and 458 eelpout (Zoarces viviparus) specimens. Fish was collected during bi-annual sampling campaigns performed in 2001 and 2002. Statistically significant differences (p < 0.0001) regarding season and sampling location were recorded. The highest values of cytogenetic damage were registered in flounder from the Lithuanian coast near Palanga (autumn 2001) and from the Wismar Bay (spring 2001), in perch from the Lithuanian coast near Nemirseta (autumn 2001) and in eelpout from the Wismar Bay (autumn 2001). These values are 5–10-fold higher than the baseline level of micronucleus incidence. In general, the decrease in environmental mutagenesis was observed in 2002. Nevertheless a significant increase in micronucleus levels was determined in fish after the oil spill in the Bûtingë oil terminal

  • Effects of dredging in Göteborg Harbor, Sweden, assessed by biomarkers in eelpout (Zoarces viviparus)
  • 2005
  • Ingår i: Environmental Toxicology and Chemistry. - 0730-7268. ; 24:8, s. 1951-1961
  • Tidskriftsartikel (refereegranskat)abstract
    • We used a battery of biomarkers in fish to study the effects of the extensive dredging in Goteborg harbor situated at the river Gota alv estuary, Sweden. Eelpout (Zoarces viviparus) were sampled along a gradient into Goteborg harbor, both before and during the dredging. Biomarker responses in the eelpout before the dredging already indicated that fish in Goteborg harbor are chronically affected by pollutants under normal conditions compared to those in a reference area. However, the results during the dredging activities clearly show that fish were even more affected by remobilized pollutants. Elevated ethoxyresorufin-O-deethylase activities and cytochrome P4501A levels indicated exposure to polycyclic aromatic hydrocarbons. Elevated metallothionein gene expression indicated an increase in metal exposure. An increase in general cell toxicity, measured as a decrease in lysosomal membrane stability, as well as effects on the immune system also could be observed in eelpout sampled during the dredging. The results also suggest that dredging activities in the Gota alv estuary can affect larger parts of the Swedish western coast than originally anticipated. The present study demonstrates that the application of a set of biomarkers is a useful approach in monitoring the impact of anthropogenic activities on aquatic environments.

  • Use of biliary PAH metabolites as a biomarker of pollution in fish from the Baltic Sea
  • 2006
  • Ingår i: Marine Pollution Bulletin. - 0025-326X. ; 53:8-9, s. 479-487
  • Tidskriftsartikel (refereegranskat)abstract
    • During field campaigns of the BEEP project (Biological Effects of Environmental Pollution in Marine Coastal Ecosystems) in 2001–2002, metabolites of polycyclic aromatic hydrocarbons (PAHs) were determined in bile samples from three fish species, flounder (Platichthys flesus), perch (Perca fluviatilis) and eelpout (Zoarces viviparus), from four separate areas in the Baltic Sea. Two determination methods were applied: fixed wavelength fluorescence (FF) for pyrene-type metabolites and high-performance liquid chromatography with fluorescence detection (HPLC). There was a good correlation between the FF method and 1-OH pyrene determined by HPLC. Normalisation of the FF data for absorbance at 380 nm or bile protein concentrations greatly increased variance in one third and decreased it in two thirds of the cases and resulted in a loss of significant differences (protein normalisation) between the sampling stations, but normalisation of the HPLC data had little effect on the results. The biliary PAH metabolite content was usually higher in males than in females. In perch and eelpout the biliary PAH contents were at similar levels, whereas in flounder the levels were lower. The sampling areas arranged in decreasing order of biliary PAH contents were: Wismar Bay > Gulf of Gdansk > Lithuanian coast > Kvadofjärden (reference area). It is concluded that FF with un-normalised data is a reliable and simple method for monitoring purposes and only one sex of a selected species should be used.
