Indices for the assessment of environmental pollution of the Baltic Sea coasts: integrated assessment of a multi-biomarker approach.
Katja Broeg,Kari K. Lehtonen +1 more
TL;DR: Two mathematical methods to assess the "health status" of flounder, eelpout and blue mussel populations of the Baltic Sea were applied on selected biomarker data collected during the EU project "BEEP" to produce essentially similar results.

Journal ArticleDOI
Seasonal variability in biomarkers in the bivalves Mytilus edulis and Macoma balthica from the northern Baltic Sea.
Sari Leiniö,Kari K. Lehtonen +1 more
TL;DR: Strong seasonal variability in temperature and a concentrated period of food availability in spring-both governing the reproductive cycle of the bivalves-probably explains most of the observed natural variability in biomarkers in this sea area.
Journal ArticleDOI
Biomarker responses as indication of contaminant effects in blue mussel (Mytilus edulis) and female eelpout (Zoarces viviparus) from the southwestern Baltic Sea

TL;DR: In a field study performed in spring and autumn 2001 and 2002, blue mussels (Mytilus edulis) and female eelpout (Zoarces viviparus) were collected at three locations in the Wismar Bay (Baltic Sea), and several biomarkers of contaminant effects were analysed as discussed by the authors.
Journal ArticleDOI
Nutrient Fluxes, Porewater Profiles and Denitrification in Sediment Influenced by Algal Sedimentation and Bioturbation by Monoporeia affinis
Liisa Tuominen,Kalervo Mäkelä,Kari K. Lehtonen,Hannu Haahti,Susanna Hietanen,Jorma Kuparinen +5 more
TL;DR: In this paper, the effects of addition of algae (340 mg C m−2) and of the amphipod Monoporeia affinis on denitrification; porewater nutrient profiles; nutrient fluxes between sediment and water; and bacterial production were studied.
