Sintef is carrying out both standard and customised ecotoxicological studies on organisms on different trophic levels, as well as studies of fate and degradation of organic substances in biological systems.
Many of these studies are aimed at supplying basic data on toxicology and biological uptake/depuration and biodegradation for risk assessment calculations for instance in the DREAM-model.

• Fate and effects of oil and produced water components in natural seabed ecosystem - Simulated seabed studies. 
• Fate and effects of oil and produced water components in the water column.
• Effects of water accommodated fraction and oil droplets on planktonic organisms and fish.
• Meso-scale system for studying fate effects of the contaminants on benthos in and on shoreline sediment.
• Recipient ecological surveys (fauna characterisation).
• Studies of food-chain transfer of oil and chemicals.
• Ecotoxicological testing according to OSPARCOM
  - Acute toxicity tests: Microtox assay, Marine algae growth inhibition test (Skeletonema costatum), Marine fish acute toxicity test (Scophthalmus maximus), Marine sediment re-worker test (Corophium sp.)
  
  - Biodegradation tests: Biodegradability in seawater - biological oxygen demand (BOD), Anaerobic biodegradability - measurements of bio-gas production.
  
  - WAF characterisation test: (customised): Calanus finnmachicus (LC50)
