Identifying wastewater chemicals in coastal aerosols

This dataset accompanies our Science Advances manuscript investigating the aerosolization of wastewater-derived contaminants from the Tijuana River along the U.S.–Mexico border. It includes raw and processed data used to assess the spatial distribution and atmospheric transport of contaminants from coastal waters into the air. Files include: (1) Data tables with air mass origin assignments and quantified contaminant concentrations; (2) raw mass spectrometry data files and (3) links to external repositories hosting pre-processed MS and MS/MS data, as well as Global Natural Products Social Molecular Networking (GNPS) visualizations. These data support the spatial and chemical analyses presented in the manuscript and are intended to facilitate transparency, reproducibility, and further research on coastal aerosol pollution., , # Identifying Wastewater Chemicals in Coastal Aerosols

## Description of the data and file structure

This dataset accompanies our *Science Advances* manuscript investigating the aerosolization of wastewater-derived contaminants from the Tijuana River along the U.S.–Mexico border. It includes raw and processed data used to assess the spatial distribution and atmospheric transport of contaminants from coastal waters into the air. Files include: Data tables in .csv format of (1) calibration curve data, (2) mass spectral intensities and concentrations of field sample data, (3) concentration metadata, (4) air mass origin assignments, and (5) raw mass spectrometry data files that may be viewed or processed in mzmine or similar software packages available externally. These data support the spatial and chemical analyses presented in the manuscript and are intended to facilitate transparency, reproducibility, and further research...,
