Micropollutant fluxes in urban environment: a catchment perspective. [Dataset]

Abstract

Anthropogenic substances, such as pharmaceuticals, pesticides, plasticizers, UV filters, industrial chemicals etc., have been widely recognised to be entering the environment from a variety of sources. There are many studies that detail the presence of a range of compounds in a variety of matrices, however the majority of this existing work has been focused on one or two classes at a time, or a small number of compounds of emerging concern (CECs), primarily in aqueous matrices. The aim of the paper is to investigate the changes in micropollutant load throughout a river catchment system in the South-West of the UK, to gain further information on their sources, fate and behaviour. This was achieved by undertaking a comprehensive investigation of 142 CECs, previously prioritised and analytical method validated (Proctor et al., 2019), at five strategic WwTWs representing >75 % of the catchment population. At each WwTW, influent (both liquid and solid phases) and effluent wastewater, digested solids, and upstream and downstream river water were monitored for 7 consecutive days.

• Collection Method: Samples were collected at each of the five WwTWs (A-E) for 7 consecutive days between June and October 2015. Sampling was carried out using volume proportional sampling for influent wastewater, time-proportional for effluent and grab sampling for river water upstream and downstream of the effluent discharge point. Digested sludge was collected, via grab sampling, on three consecutive days from WwTW B and WwTW E. Liquid samples were spiked with internal standards and analytes extracted by solid phase extraction (SPE) using OASIS HLB cartridges before analysis with ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) (Waters). The solid samples were frozen, freeze-dried, homogenised, weighed and spiked with internal standard before undergoing microwave assisted extraction (MAE) followed by SPE with OASIS MCX cartridges.
