Field validation of the nickel EQS

Pete, Graham, and I have just published a paper on validating the proposed EQS for nickel by a comparison against field evidence from the UK. Compliance with an EQS of 4 μg/L “bioavailable nickel” is highly unlikely to prevent communities achieving good ecological status.

Ecological Indicators for abandoned metal mines

Metal mining in the UK has occurred for thousands of years and was widespread during the 18th and 19th centuries. This activity has resulted in a legacy of abandoned metal mine sites across the UK. We were recently commissioned by the Environment Agency to undertake a project to investigate whether conventional EQS are suitably protective of aquatic life in waterbodies impacted by abandoned metal mines, or if higher metal concentrations than the EQS can be acceptable in these waterbodies without risk to aquatic life. Importantly, we were asked to explore how these instances could be accommodated within the WFD to enable the status of the water body to be correctly classified. The results of this project are now available to download.

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.

Simplifying the implementation of bioavailability-based water quality standards for metals

Graham and I are continuing to work toward the practical implementation of bioavailability based water quality standards for trace metals, in collaboration with European researchers and the European Copper Institute.

Soil Quality Standards for Trace Elements: Derivation, Implementation, and Interpretation

In 2008 a Society of Environmental Toxicology and Chemistry-sponsored Technical Workshop was held in Sydney, Australia. The book of the deliberations from this workshop has now been published.
