    • 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

  • 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.
