Short summary
The influence of anthropogenic pollution on atmospheric organic composition was studied to explore the chemical processes of anthropogenic–biogenic interactions in the Qinling Mountains region of central China using advanced Orbitrap mass spectrometry. Organic molecular species exhibited distinct seasonal variabilities and were more abundant and chemically diverse in winter. Anthropogenic pollution played key roles in altering their composition and related properties under various conditions.
