Supplementary materials - Numerical simulation of PM2.5 dispersion originated from vehicular traffic in urban environments: Situational validation of proposed biomonitoring method

A collection of archived files accompanies this study, including:

• Fluent case & mesh: full ANSYS Fluent project with the 14.8 M-cell mesh and solver settings.

• DPM outputs: time‐step particle tracks and fate data.

• Flow fields: streamline and pressure snapshots at key instants.

• Biomonitoring data: raw heavy‐metal concentration tables and sampling metadata.

• Supporting geometry: porosity calibration files and photogrammetry scans.

Together, these files enable full reproduction and further exploration of our CFD simulations and biomonitoring analyses.
