Short summary
This study reveals that summer aerosols over the Bohai and Yellow Seas are mainly influenced by coastal emissions. Despite a high proportion of marine air masses, molecular and isotopic analyses of aerosols show strong terrestrial characteristics. Biomass burning contributes 60–80 % of carbonaceous aerosols, while marine sources account for only ~ 20 %. The findings highlight that controlling coastal emissions within ~ 260 km is crucial for mitigating marginal sea pollution.
