Seasonal changes in organic carbon (OC) and elemental carbon (EC) sources in Xi'an, China, are investigated based on measurements of radiocarbon and the stable isotope 13C. Relative contributions to EC from biomass burning, coal combustion, and vehicle emissions change substantially between different seasons. Biomass burning contributes 60 % to the EC increment in winter. Comparing concentrations and sources of primary OC to total OC suggests non-negligible OC loss due to active photochemistry.
