Abstract

The study was aimed to evaluate the ability of native lichen Xanthoria (X.) parietina to biomonitor and bioaccumulate some heavy metals (As, Cd, Co, Cr, Ni, Pb), PAHs, PCDDs, PCDFs, PCBs and PBDEs and to evaluate the use of the native X. parietina as a multi-tracer tool for scenarios characterized by different anthropogenic pressures. Samples of native X. parietina were collected in six different sites (two green, two residential and two industrial areas, respectively) and analyzed for the target compounds. The results show that X. parietina was a useful tool for the biomonitoring of air quality in the selected areas, and was able to bioaccumulate all the studied metals and POPs. In particular, the total concentrations dry weight (dw) ranged between 8.1 and 103.4 mg kg−1 for metals, from 113 × 103 to 183 × 103 ng kg−1 for PAHs, from 868 to 7685 ng kg−1 for PCBs, from 14.3 to 113.8 ng kg−1 for PCDDs/Fs (∑TEq = 0.9–7.1), and from 194 to 554 ng kg−1 for PBDEs. Besides, in general, the levels of analytes recovered in the different samples of lichen show an increasing trend from green to industrial sites, especially for PCBs (mean values equal to 1218, 4253 and 7192 ng kg−1 respectively for green, residential and industrial areas). The statistical approach, based on Pearson's correlation and principal component analysis tests, showed that one of the industrial sites was well-separated from the others, that resulted grouped due to some similarities. The lichen Xanthoria parietina is a useful tool for biomonitoring outdoor air quality. It is able to bioaccumulate metals and POPs and to discriminate between scenarios characterized by different anthropogenic pressures.
