Effects on iron on ecological communities
Mark and I have been working with the Iron industry to try to understand the effects of iron on aquatic ecosystems. We have been analysing extensive field monitoring data on the quality of invertebrate communities in rivers and relating this to the levels of different forms of iron (total, dissolved, or particulate) that are present.

Environmental Quality Standards and Field Evidence
We have recently been using a new approach to derive an Environmental Quality Standard for iron from ecological field evidence. The approach has the potential to align acceptable levels of iron in the environment with established levels of ecological quality under the Water Framework Directive. This has never been possible before, and may allow a much greater degree of integration of chemical and ecological criteria for freshwater in the future.
