Geochemical results from stream-water and stream-sediment samples collected in Colorado and New Mexico

Data from a study intended to explore how well the chemical analysis of water and sediment in an area reflects that of the rock from which the sediments are eroded and through which the water flows.

Using biotic ligand models to predict metal toxicity in mineralized systems

<p><span>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
