- •
δ34Snss in PM2.5 is effective to estimate contribution of anthropogenic sulfur.
- •
δ34Snss have characterized with seasonal variation with high values in winter.
- •
The contribution of transboundary transport is 39-81% at the site facing to the Sea of Japan.
- •
δ34Snss in PM2.5 are modified during transport with mixing of domestic sources.
- •
Map of δ34S distribution originated from coal in Northeast Asia is developed.
