Mixtures of sediment chemical contaminants at freshwater sampling sites across Europe with different contaminant burdens (2023)
Journal Article
Richardson, S., Mayes, W. M., Faetsch, S., Hetjens, H., Teuchies, J., Walker, P., …Heise, S. (2023). Mixtures of sediment chemical contaminants at freshwater sampling sites across Europe with different contaminant burdens. The Science of the total environment, 891, Article 164280. https://doi.org/10.1016/j.scitotenv.2023.164280

Extended chemical analyses of fluvial sediments were undertaken to establish the key pollutant pressures and mixtures present across nine European Union inland waterways. A wide range of chemical components and physical parameters were investigated i...
