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.

Statement: Samples collected from 17 sites along the River Tone and 16 sites along the River Wensum in 2021 and 2022. Water samples were filtered and were spiked with internal standards prior to dSPE. Sediment samples were freeze-dried, sieved and ball-milled to <250 ?m. Samples were extracted using modified versions of the QuEChERS extraction (EN-method) and clean-up (AOAC-method) methods. All samples spiked with IS mix (Propamocarb-d7, Carbdendazim-d3, Acetamiprid-d3, Atrazine- d5, Propiconazole-d3, Prochloraz-d4, Dimethoate-d6). Samples were analysed using a UPLC-MS/MS fitted with a Hypersil GOLD C18 column. MS/MS was performed in SRM mode using ESI in positive mode. LC/MS conditions were based on recommendations from the column manufacturer. Detection and quantification based on precursor and product ions of the 52 analytes using a 7-level calibration for both water and sediments.
