Pharmaceutical concentration data - two spatial snapshots of the Aire River Catchment (UK) in low flow (LF - April 2022) and high flow (HF - March 2023)

The data presented here represents the result of two spatial sampling campaigns performed in the Aire river Catchment (Yorkshire, UK) in April 2022 and March 2023 as part of a PhD research project. Details about the project: https://iconn.network/early_stage_researchers/early-stage-researcher-15/. The two snashots were collected in low flow (LF) and high flow (HF) conditions. Each snapshot was created by collecting samples from all sites within a window of nine hours over the course of a single day. The LF snapshot was collected in Spring 2022 (April 6th 2022), when flow conditions corresponded to Q32 - gauged daily flow of 17.2 m3/s, and the HF snapshot in Spring 2023 (March 14th 2023), when flow conditions corresponded to Q03 - gauged daily flow of 63.8 m3/s. The samples were analysed using Liquid Chromatography with tandem Mass Spectrometry (LCMSMS), and the concentrations of nine target compounds were determined. The method used to measure the concentrations of targeted pharmaceutical compounds was Method TM432 - Determination of PPCPs (Pharmaceuticals and Personal Care Products) in Liquid by LCMSMS . The sheets included in this file are data (the raw data), data_explanation (details about what each column of the data sheet represents, e.g units), LODs (limits of detection of the analytical method), sampling_sites (information about the sampling sites) and sampling_sites_explanation (details n about what each column of the sampling_sites sheet represents). This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 859937. Special credit goes to the volunteers that helped collect this data: Laura Turnbull-Lloyd, Sim Reaney, Jennifer King, Danai Kontou, Matthew Wiecek, Muyeol Jung, Ying-Tong Lin, Cristina Balaban, Raphael Kahlenberg and Aaron Neill, as well as the many others who offered their time on alternate dates. Mervyn Brown and Sion Kennaway were especially instrumental in helping with equipment and lab work.
