Lars Sonesten
I am a limnologist and ecotoxicologist working mainly with water chemistry and biology in inland waters. I am also working with the inputs of nutrients and hazardous substances to the Sea.

Presentation

  • Head of the Department of Aquatic Sciences and Assessment
  • SLU representative, Steering Committee of the Swedish Environmental Emissions Data (chairman 2010, 2014, 2015) (SMED)
  • Chairman of HELCOM Pressure (a consists of the former expert groups LOAD [Waterbourne, and atmospheric loads to the Sea, and the follow-up of national progress towards reaching BSAP nutrient reduction targets], LAND [landbased point sources]. The new group are also commissioned to lead and coordinate the HELCOM work on Marine litter and Underwater noise)
  • Chairman of OSPAR INPUT, the OSPAR expert group on waterbourne and atmospheric inputs to the North Atlantic ocean
  • Member of the UN Pool of Experts for the 2nd United Nations World Ocean Assessment
  • NJ Faculty respresentative, Steering committee of SLU Data Curation Unit.
  • SLU representative, Digitally first - Waters and the Sea (Digitally first is a SEPA mission by the Swedish government to develop environmental information to society).
  • The Uppland Foundation (Upplandsstiftelsen) Water Management Board
  • Board Member for the Lake Vänern LTER site

Teaching

  • Course director for a 10-week undergraduate course in Ecotoxicology (stand-by since 2013)
  • Lecturer in a 3-week graduate course in Multivariate methods for ecologists
  • Lecturer in Ecotoxicology at the two SLU courses in Contaminated soils - Risk Assessment and Remediation (20 and 5 credits)

Research

My present work is mainly focused on:

  • Assessments of long-term trends in water chemistry and biological composition, and food web interactions (including fatty acids as tracer substances) in lakes and watercourses.
  • Nutrient cycling and source apportionment in aquatic systems and watersheds.
  • Load of nutrients and hazardous substances to the Sea.
  • Risk assessment of heavy metals and organic environmental pollutants in freshwaters, biota, and sediments.

Environmental analysis

Ongoing projects

  • Estimates of the annual Swedish emissions of nutrients and other substances to the Baltic Sea, and the Northeast Atlantic Ocean.
  • Assessments of the methodology for estimating the riverine and diffuse nutrient load on the Sea.
  • Evaluation of water chemistry and biological composition in regional monitoring programs.
  • The HELCOM PLC 7 reporting (Pollution Load Compilation no 7) including revision of reporting routines and responsability for the assessment of the inputs of hazardous substances.
  • Participates in two HELCOM projects, HELCOM Action (nutrients) and HELCOM SoM (other pressures), assessing if  launched and planned remedial measures are sufficient to fulfil the goals in the Baltic Sea Action Plan (BSAP).
  • Assessing the world oceans with focus on inputs of nutrients and hazardous substances to the Baltic Sea and the Norteast Atlantic Ocean in the 2nd UN World Oceans Assessment.

Background

  • PhD in Limnology, Uppsala University 2000
  • MSc in Ecotoxicology, Uppsala University 1989
  • BSc  in Biology, Uppsala University 1987
