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.

Spatial patterns for lichen element concentrations based on the Kriging interpolation of the HDT outputs of the sampling sites.(a) Ca, Cs, Mg and Tl (cluster H). (b) Na, K, Sm and Tb (cluster B). (c) Ce, La and Rb (cluster C). (d) Al, Ba, Fe, Sc, Sr, Ti and V (cluster A). (e) Co, Mn, Ni and Th (cluster D). 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 patterns for the G1 elements are given in Fig. 3a–f. Ca, Mg, Cs and Tl show a decreasing pattern from north to south (Fig. 3a) while a reverse pattern is observed for K, Na, Sm and Tb (Fig. 3b). Concentrations of Ce, La and Rb were high near Fuping (sites S8, 9, 10, 14) and Tangxian (S11; Fig. 3c). The patterns for clusters A and D were similar, characterized by higher concentrations near Fuping (S9), Tangxian (S11) and Jingxing (S21), and lower concentrations at sites S1–7 (Fig. 3d,e).
