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.
