Aerosol and Air Quality Research
A Machine Learning Approach to Predicting Air Quality and Health Risks for Construction Worker Safety
This study successfully applies machine learning models to monitor and predict air quality at construction sites, assessing health risks for worker safety. Utilizing Decision Tree regression and classification, the models achieved high predictive accuracy (R-squared > 0.95) for pollutant trends and over 91% accuracy in health risk estimation. Findings from three Dubai construction sites (apartment building, villa, townhouse) revealed elevated pollutant levels at high-rise sites, emphasizing the need for targeted mitigation strategies. The Emirati Air Quality Index (EAQI) highlighted poor air quality during peak construction phases. The robustness of the models was confirmed through testing on a new townhouse site. This research validates the feasibility of using predictive models for proactive air quality monitoring and health risk management in dynamic construction environments.

Site-Specific Air Quality Insights from Dubai Construction Projects
Detailed monitoring across three distinct construction sites in Dubai—a high-rise apartment building, a two-floor villa, and a new townhouse—revealed significant variations in pollutant levels and associated health risks. The high-rise site consistently showed higher average pollutant concentrations, particularly for PM1.0, PM2.5, PM10, and CO2, due to its larger scale, more intensive activities, and higher worker density. In contrast, the villa site exhibited lower overall pollutant levels, attributed to its smaller size, fewer workers, and less intensive operations. The new townhouse site, used for model validation, also presented relatively higher CO2, PM2.5, and PM10 concentrations, influenced by its construction area, activity types, and the proximity of multiple units being built simultaneously. These findings underscore the critical need for targeted mitigation strategies and highlight how the predictive models can guide proactive measures specific to each construction environment.
