Tasks

 I work as an ecotoxicologist in the Ecotoxicology and Risk Assessment –group where the major tasks relate to biotesting of environmental samples and chemicals, expert guidance for our environmental administration (local and central) and research in aquatic environment. We use standard biotests as effect-based methods in research projects but also in commercial orders. The major matrix is aquatic but also extracts of all kind of solid samples are in program. My role in central environmental administration also requires method development and duties in standardization organizations and quality assurance work.

International activities

  • National coordinator in the OECD Test Guideline programme (OECD)
  • National coordinator of the EU Test Methods
  • Member of the Nordic cooperation group in chemical test methods (Nordisk koordinering for Udvikling af Testmetoder inden for Toksikologi og Økotoksikologi, NordUTTE)
  • Member of the ISO/TC 147 Water Quality SC5 Biological methods (National chair 2020-)
  • Member of the CEN/TC 230 Water analysis WG2 Biological methods co-ordination group
  • Member of the SETAC Metals Interest Group steering committee 

Background

Before I joined SYKE 2012 I did research and teaching in University of Joensuu/Eastern Finland starting as a PhD student (1995) and going through the whole academic career ending up to university researcher and professor in ecotoxicology (-2012). The major interest were in aquatic and sediment toxicology and food web bioaccumulation.

Major interests

  • Bioavailability and effects of metals and organic chemicals (especially EDCs) in ecosystems
  • Development and application of effect-based methods (EBMs) for Finnish aquatic ecosystems
  • The role of WWTPs in environmental contamination – Combining effect-based methods with hydrodynamic distribution models
  • Risk assessment of sediment associated contaminants
  • Use and development of passive sampling devices and EBMs for assessing environmental contamination
  • Developing passive sampling materials for air sampling using drones
  • Bringing hydrodynamic distribution models into aquatic ecotoxicology
  • The role of harmful contaminants in circular economy – recycling and chemicals; a problem?

Recent research projects (2015-)

  • Are the Biotic Ligand Models (BLM) suitable for assessing the ecological risk of metals in Nordic freshwaters? (BLMNordic)
  • Contaminated Sediments: Review of solutions for protecting aquatic environments (ConSEns)
  • Impact of micropollutants emitted from municipal wastewater treatment plants on Baltic Sea ecosystems and assessment of costs-benefit of advanced treatment technologies in a regional perspective (MicroWasteBaltic)
  • Multiple lines of evidence in assessing ecotoxicological and human health risks of mine effluents and public perception (Mineview)
  • Management and restoration of recipient waters influenced by mining effluents (KaiHali)
  • Bioassays as tools for assessing safety of sewage sludge fertilizer usage - harmful substances and microplastics under observation (BIOLTA)
  • Efficient treatment of pharmaceutical residues at source (EPIC)
