These files contain the LC-QTOF-HRMS data associated with the manuscript:

M.F.T. Sá et al.
Tracking pollutants in a municipal sewage network impairing the operation of a wastewater treatment plant
Science of the Total Environment, 2022, 817, 152518
https://doi.org/10.1016/j.scitotenv.2021.152518

Data was acquired with an Agilent 6550 QTOF in both:
- AutoMSMS (data-dependent acquisition, DDA) 
- All Ions (data-independent acquisition, DIA)

Data is provided in Agilent MassHunter B.10.00 format.

In the case of AutoMSMS the iterative mode with two injections per sample was employed.
Further details on how samples were processed is presented in the manuscript.

Data is therefore structure in two folders, one for DDA and one for DIA.
Each folder is then further divided between positive and negative mode.

Files are named accordingly to the sample, using the same codes than in the manuscript.
The number after the code refers to the sample campaign.
Besides, there are "A" and "B" files in the DDA files, corresponding to the first and second iterative injection, respectively.

As an example, the file:
PVZ-2 2_B.d in the AutoMSMS_DDA (either pos or neg) folder:
corresponds to the sample PVZ-2 from the second sampling campaign and second injection
