Pesticide concentrations in the River Tone, Somerset, and the River Wensum, Norfolk

Measured concentrations of 52 different modern pesticides in both waters and sediments. Collected during routine sampling as part of the PhD project "Assessing the Impacts of Organic and Inorganic Contaminants on British Rivers: from Sediments to Fish". Samples were collected in 2021 and 2022, and pesticides were measured using UPLC-MS/MS at the British Geological Survey. Site coordinates are included in a separate tab. Full detail on sample collection, analytical methodology and data summaries, including interpretations, can be found in the accompanying thesis.
