Bottom Line: Air pollution is a major concern in China.Epilithic foliose lichen Xanthoria mandschurica was sampled from 21 sites and analyzed using inductively coupled plasma mass spectrometry (ICP-MS).The results show that 1) eight elements (Cd, Cr, Cu, Mo, P, Pb, Sb and Zn) are of atmospheric origin and are highly influenced by the atmospheric transportation from the North China Plain, as well as local mining activities, while 2) the remaining 22 elements are primarily of crustal origin, the concentration of which has been enhanced by local mining and quarrying activities.

ABSTRACT
Air pollution is a major concern in China. Lichens are a useful biomonitor for atmospheric elemental deposition but have rarely been used in North China. The aim of this study was to investigate the atmospheric depositions of 30 trace elements (Al, Ba, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, Rb, Sb, Sc, Sm, Sr, Tb, Th, Ti, Tl, V and Zn) in a region of the Taihang Mountains, Hebei Province, China using lichens as biomonitors. Epilithic foliose lichen Xanthoria mandschurica was sampled from 21 sites and analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The results show that 1) eight elements (Cd, Cr, Cu, Mo, P, Pb, Sb and Zn) are of atmospheric origin and are highly influenced by the atmospheric transportation from the North China Plain, as well as local mining activities, while 2) the remaining 22 elements are primarily of crustal origin, the concentration of which has been enhanced by local mining and quarrying activities. These results clearly validate the applicability of lichens in biomonitoring of atmospheric elemental deposition and demonstrate the spatial pattern for air pollution in the region.

(h) P (EFSR). EFSR, EF normalized to averaged local SRs. The white squares denote sampling sites. The lichen is Xanthoria mandschurica. The HDT outputs, produced using the software Dart 2.0.5 (Talete srl 2007), were subjected to Kriging interpolation using Past 3.10 (Ø. Hammer, Nov. 2015). Maps of the Kriging results were drawn using SigmaPlot 12.5 (Systat Software, Inc., San Jose, CA, USA). For mapping details see Fig. 1.

Mentions: The concentration and EFSR patterns for the G2 elements are given in Fig. 4a–h. The concentration pattern for Cr and Mo (Fig. 4a) was similar to the EFSR pattern (Fig. 4b), which was also highly similar to the concentration pattern for Mn, Ni, Co and Th (Fig. 3e), as expected from their close relationships (Fig. 2). Concentrations for Cu and Sb were highest near Tangxian (S11 and S12) and also high along the line from S17 to S4 (Fig. 4c). Concentrations for Cd, Pb and Zn show a different pattern with a decreasing trend from east to west and a northwestward tailing from S19 (Fig. 4e). This concentration pattern was also observed for P, which however, showed a high concentration at sites S8 and S10 (Fig. 4g). EFSR patterns for Cd, Cu, P, Pb, Sb and Zn were more or less similar, with a westward decreasing trend from S1, S2, S5 and S6, and a northwestward tailing from S19 (Fig. 4d,f,h).
