Short summary
We continuously performed a one-year and hourly-resolved measurement of 18 atmospheric elements in PM2.5 in Shanghai megacity. Here our high time-resolution observations over a long-term period provide baseline data with high detail, which are of great use for examining acute exposure of morbidity and mortality risk in association with PM2.5 metal species in China's megacities.
