“…The relationship between metal content and tra c volume showed that metallic elements, emitted as pollutants derived from vehicles and also industrial emissions that spread (Kar et al, 2013). Furthermore, a recent study conducted by Liu et al (Liu et al, 2017) and Petrova et al (Petrova, 2015) found that anthropogenic and urban tra c activities were a very important factor in increasing the accumulation of metals such as Cd, Zn, Pb, Fe and Cr. The further the distance from the highway accumulation of heavy metals is getting lower.…”

Flavoparmelia caperata and Usnea dasypoga lichen for the first time was used to assess the concentration of heavy metals in the air in Palembang City. Five heavy metals Cd, Cu, Pb, Fe, and Zn were measured using the transplant method. Both samples of lichen were collected from Gununghalu, Bandung. The lichen was transplanted at 7 points on the roadside, after 8 weeks, samples were collected and analyzed using atomic adsorption spectrometry (AAS). The concentration of heavy metals accumulated in F. caperata was Fe> Cu> Zn> Pb> Cd, on U. dasypoga was Fe> Zn> Cu> Pb> Cd. The results showed that both types of lichen were very suitable to be used as an air quality bioindicator. The EC ratio of both transplanted samples showed higher levels of accumulation in U. dasypoga with a significant accumulation rate on Pb metal followed by Cu, Cd, Zn, and Fe. Furthermore, dendrogram showed clustering based on the concentrations of heavy metals accumulated at each station due to differences in density and vehicle type. This indicated that the metals have the same source which derived from emissions of motor vehicles, road construction activities, and other local anthropogenic activities.

Road-based transport emissions are a major source of atmospheric metal pollution. However, there have been few studies on emissions from road traffic in mountainous areas. In this study, epiphytic mosses from trees at different elevations of a highway, a typical road with extraordinary elevation change in a mountainous area of karst in Guizhou, China, were analyzed for metal content as well as the spatial distribution pattern of metals. Mosses were sampled from three sections of highway at different elevations, from 1292-1357, 1394-1441, to 1481-1548 m. Principal component analysis and heat-map clustering were used to identify the principal factors affecting metal deposition. The results show that the metals of mosses from different elevations were divided into four factors. Group 1 which included Ni, Fe, Mg, Ba, and Al was attributed to a dominantly geogenic source. Group 2 included Zn, Cu, Mn, and Cr, from vehicle-related materials including tires and brakes. Group 3, Cd, can be attributed to high Cd background levels from local origins and traffic emissions, particularly tire wear. Group 4, Pb, is associated with brake wear and historical deposition. The epiphytic moss widely distributed in the study area, Ectropothecium aneitense Broth. & Watts, was used to analyze the spatial distribution pattern of the metals. Metal content gradually decreased with increase in elevation. Levels of Ni, Fe, Mn, Ba, and Cd were all significantly correlated with elevation (p < 0.05), simultaneously affected by terrain and vertically stratified. We highlighted the vertical distribution characteristics of metal in epiphytic mosses in this study, which could improve moss application for ecological monitoring due to road-based transport emissions with elevation changes.
