General note Continuous deposition of workplace pollutant particles on lung airways<br/>during respiratory actions seriously threatens the lung health of persons<br/>performing tasks in polluted environments. While inhalation-deposition<br/>relationships have been explored, the impact of exhalation on the deposition<br/>of polydisperse particles remains unclear. This study aims to analyze the<br/>exhalation-driven deposition of fine and coarse occupational pollutant<br/>particles in polydisperse form, considering varying levels of physical activity.<br/>Computer simulations are conducted on the airway section G3-G4 to study<br/>the patterns of airflow dynamics and deposition of grain dust, coal fly ash, and<br/>bituminous coal particles across a spectrum of activity intensities, utilizing<br/>idealized and realistic lung models. Key findings include the observation of<br/>early emergence of secondary flows in the real model compared to the<br/>idealized model, a notable shift in deposition patterns towards the postbifurcation zones, and the influence of physical activity intensity on particle<br/>deposition. Additionally, deposition primarily occurs near the cranial ridge<br/>during inhalation, while exhalation leads to deposition in pre- and postbifurcation zones. The effect of gravity on deposition is more pronounced at<br/>lower flow rates but diminishes at higher flow rates. PM2.5 deposition isxv<br/>minimal and random in the idealized model but becomes more significant and<br/>consistent in the real model, with substantial deposition rates observed for<br/>PM10 particles. This research underscores the increased risk of lung diseases<br/>for workers in polluted environments during vigorous activity.
