Unraveling the long-term dynamics of black carbon and co-emitted air pollutant sources over the East China Sea.

Puntos clave

• The study aims to understand the long-term dynamics of black carbon and associated air pollutants in the East China Sea.
• Integrated approach analyzes the sources and removal rates of black carbon (BC).
• Focus on comparing regional and local BC scavenging efficiency.
• Assessment of ship emission control effectiveness for air quality management.
• Wet scavenging rates show regional BC is removed twice as effectively as local BC.
• Evaluation indicates a 44% reduction in total BC from intervention measures.
• Insights inform better management strategies for improving coastal air quality.
