The Biotic Ligand Model (BLM) is a tool used in aquatic toxicology that examines the bioavailability of metals in the aquatic environment and the affinity of these metals to accumulate on gill surfaces of organisms. BLM depends on the site-specific water quality including such parameters as pH, hardness, and dissolved organic carbon. In this model, lethal accumulation values (accumulation of metal on the gill surface, in the case of fish, that cause mortality in 50% of the population) ar… WebBio-met is a user-friendly tool to assess Environmental Quality Standard (EQS) compliance of metals under the EU Water Framework Directive.

WebJun 1, 2015 · The biotic ligand model (BLM) is a numerical approach that couples chemical speciation calculations with toxicological information to predict the toxicity of aquatic metals. This approach was proposed as an alternative to expensive toxicological testing, and the U.S. Environmental Protection Agency incorporated the BLM into the 2007 revised ...
