Presentation / Conference Contribution
Riley, A. L., Onnis, P., Gandy, C. J., Kanu, C. V., Umeobika, C. V., Cameron, J., Burke, I. T., Hudson-Edwards, K. A., Jarvis, A. P., & Mayes, W. M. (2023, July). The Contribution of Major Historical Orefields to Coastal Trace Metal(loid) Fluxes in North-East England. Presented at IMWA 2023 – ”Y Dyfodol | The Future”, Newport, Wales

Mine waters and tailings are key inputs to riverine metal(loid) transport to the coast. However, coastal areas also face local contaminant pressures, e.g. active industries and abandoned landfill sites. Annual riverine metal(loid) flux data were asse...

Ikaite formation in streams affected by steel waste leachate: First report and potential impact on contaminant dynamics (2023)
Journal Article
Bastianini, L., Rogerson, M., Brasier, A., Prior, T. J., Hardman, K., Dempsey, E., Bird, A., & Mayes, W. M. (2024). Ikaite formation in streams affected by steel waste leachate: First report and potential impact on contaminant dynamics. Chemical Geology, 644, Article 121842. https://doi.org/10.1016/j.chemgeo.2023.121842

Highly alkaline (pH 9–12) waters can arise from a range of globally significant and environmentally impactful industrial processes such as lime, steel and cement production, alumina refining and energy generation (e.g. combustion ashes). Such residue... Read More about Ikaite formation in streams affected by steel waste leachate: First report and potential impact on contaminant dynamics.

Antimony and arsenic behaviour in lead/zinc mine tailings during storage under vegetation cover (2023)
Journal Article
Burke, I. T., Courtney, R., & Mayes, W. M. (2023). Antimony and arsenic behaviour in lead/zinc mine tailings during storage under vegetation cover. Applied geochemistry : journal of the International Association of Geochemistry and Cosmochemistry, 158, Article 105806. https://doi.org/10.1016/j.apgeochem.2023.105806

The high-volume, fine grained tailings produced from Pb/Zn ore processing need to be carefully managed. Metalloid elements, As and Sb, are present in tailings at ∼800 and ∼80 mg kg−1 respectively, and in neutral pH leachates at 5–50 μg L−1. Despite t...

Enhanced weathering is a carbon dioxide (CO2) mitigation strategy that promises large scale atmospheric CO2 removal. The main challenge associated with enhanced weathering is monitoring, reporting, and verifying (MRV) the amount of carbon removed as...

Pollutant accumulation in road mitigation tunnels for amphibians: A multisite comparison on an ignored but important issue (2023)
Journal Article
White, K. J., Mayes, W., & Petrovan, S. O. (2023). Pollutant accumulation in road mitigation tunnels for amphibians: A multisite comparison on an ignored but important issue. Frontiers in ecology and evolution, 11, Article 1133253. https://doi.org/10.3389/fevo.2023.1133253

Underpasses or road tunnels are increasingly installed to reconnect habitats and ensure safe wildlife passage, thus preventing habitat fragmentation caused by roads and mortality from collisions with vehicles. In the UK, such underpasses are regularl... Read More about Pollutant accumulation in road mitigation tunnels for amphibians: A multisite comparison on an ignored but important issue.
