- 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

Journal article (peer-reviewed)abstract
- Frequency of micronuclei (MN) and other nuclear abnormalities (nuclear buds, bi-nucleated and fragmented-apoptotic cells) was analysed in gill cells of the blue mussel (Mytilus spp.) from selected coastal sites in the Baltic Sea-Kvadofjarden (Sweden), Klaipeda-Butinge zone (Lithuania), Gulf of Gdansk (Poland) and Wismar Bay (Germany). Samples were collected from 650 specimens during bi-annual sampling campaigns in 2001 and 2002. The lowest frequency of MN (0.37 MN/1000 cells) was found in blue mussels from the reference site (Kvadofjarden). The highest MN values (up to 6.7 MN/1000 cells) were registered in blue mussels from the Gulf of Gdansk in autumn 2001 and 2002, and at Wismar Bay in spring 2001 (up to 5.06 MN/1000 cells). Gradients of MN incidences were observed when comparing the three studied locations in Wismar Bay, and at the Lithuanian coast before the crude oil spill in the Butinge, oil terminal. Moreover, significant seasonal and inter-location differences in the responses were documented (P < 0.0001). Nuclear abnormalities were. observed most frequently in blue mussels from the Gulf of Gdansk. (c) 2005 Elsevier Ltd. All rights reserved.
