Project Details

Description

We will characterize the day-to-day fluctuation of chemical compositions and sources of fine particulate matter (PM2.5) at a representative urban site in Hong Kong for two years. We aim to establish a two-year time series of PM2.5 oxidative potential (OP) paired with daily PM2.5 composition and to characterize the complex dose-response relationships between the two. OP is an integrated indicator of PM2.5 exposure-induced oxidative stress, which is an important mechanism contributing to air pollution health effects. We will then characterize the acute health effects of distinct PM2.5 components, sources, and OP metrics with daily health data (i.e., cardiopulmonary mortality and hospital admissions) of the
general population of Hong Kong in a two-year time series study.
