Exposure models for air pollutants in Asia have been lacking, especially for particulate chemical species. A new model was developed using land-use regression to estimate exposure to four major PM10 chemical species and four criteria air pollutants in Hong Kong. The model can predict air pollutant concentrations with high accuracy and create maps showing their distribution. The study found weak to moderate correlations between different pollutants, which can help understand their health effects. This integrated model framework can be a valuable tool for assessing combined exposure and conducting health studies in densely populated urban areas.
