Short summary
To better constrain poorly resolved trace-element sources across the land-sea gradient, we applied a refined source apportionment to PM2.5 collected in Qingdao and adjacent seas in 2018. It showed that spring Fe, Mn and Cr were mainly dust-derived, although some dust aged and mixed into marine aerosol offshore. In summer, coal combustion enriched marine Zn, Pb, As and Cd, while residual oil combustion increased Fe and Mn, highlighting strong anthropogenic control on marine aerosols.
