The Cu BLM (US Environmental Protection Agency 2007) for the present analysis was updated to include several adjustments to the binding constants for the biotic ligand binding sites consistent with those used in the development of the BLM-based WQG in Canada (Environment and Climate Change …
WebOne approach for doing so is to use the biotic ligand model (BLM). The BLM allows metal–organism interactions to be taken into account and, given site-specific information on water chemistry, to evaluate the dissolved metal concentration associated with a critical level of metal accumulation that is toxic to an organism. The BLM serves as a ... WebThe biotic ligand model for copper is the U.S. Environmental Protection Agency’s current recommendation for determining freshwater aquatic life criteria for copper. This model determines site-specific criteria that account for changes in bioavailability, and thus toxicity, of copper to aquatic life due to differences in water chemistry. ...
