To assess the response of lichen elemental compositions to road traffic and species difference in the context of high dust input and anthropogenic emissions, two foliose epiphytic lichens (Phaeophyscia hirtuosa, PHh; Candelaria fibrosa, CAf) were sampled near a road adjacent to Dolon Nor Town (Duolun County, Inner Mongolia, China). Twenty elements (Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, Sb, Sr, Ti, V and Zn) in lichen and surface soil samples were analysed using inductively coupled plasma mass spectrometer (ICP-MS). The results demonstrate that lichen elemental compositions are highly influenced by both their natural environment and anthropogenic input.

- Air pollution is a significant issue in China, and the study focused on using lichens to monitor the deposition of 30 trace elements within the Taihang Mountains in Hebei Province.
- Lichens, specifically Xanthoria mandschurica, were collected from 21 sites and analyzed using ICP-MS to assess environmental contamination.
- The findings revealed that 8 elements were primarily from atmospheric sources, influenced by pollution from the North China Plain and local mining, while the remaining 22 elements were mostly crustal but elevated due to mining activities.
