Paper released: Effect of dissolved organic matter on copper bioavailability to a coastal dinoflagellate at environmentally relevant concentrations.

/, Project News, Research results/Paper released: Effect of dissolved organic matter on copper bioavailability to a coastal dinoflagellate at environmentally relevant concentrations.

This article, published in open access in The Science of the Total Environment (https://doi.org/10.1016/j.scitotenv.2023.165989), applies the use of stable Cu isotopes and demonstrates that Cu internalization depends on labile Cu at relatively high Cu concentrations (greater than 30 nM), while at lower concentrations, Cu organic complexes are partially bioavailable to the dinoflagellate. This fact questions the applicability of the Biotic Ligand Model (BLM) at typical Cu levels in coastal areas.
