Graham attended a start-up last week in Helsinki at SYKE (Finnish Environmental Institute, http://www.syke.fi/en-US), for a project focussed upon asking: Are the Biotic Ligand Models (BLM) suitable for assessing the ecological risk of metals in Nordic freshwaters? The project is funded by the Nordic Council of Ministers and is being led by Matti Leppänen of SYKE. There are also project partners from Stockholm University and the Norwegian Institute for Water Research (NIVA). Specifically, the project is aimed at validating the biotic ligand models for nickel, copper and zinc in Fennoscandinavian freshwaters that can be both soft and also relatively acidic (but have high concentrations of dissolved organic carbon). wca is providing BLM modelling support to the project with help from NiPERA, IZA, European Copper Institute and Karel De Schamphelaere from the University of Ghent. This validation will be undertaking using organisms collected from the field from water chemistry conditions similar to those to be tested. The validation is likely to be undertaken over the next year to 18 months.
