Modelling dissolved metal behaviour in the oceans
What is it about?
The behaviour of dissolved trace metals in the oceans is typically explained by invoking the concept of metal binding to specific organic chemicals (for example chemical released by aquatic plants to make it easier for them to take up essential metals). Here, using a chemical model widely used for freshwaters, we assess the extent to which non-specific organic chemicals found in the ocean (from decaying dead plants and animals) may predict the forms of cationic metals.
Why is it important?
We found that the model can give good fits in some cases, and that experimental results do not give consistent variation from the model. This has implications for the way that the availability of trace elements is considered in ocean environments.
