This paper shows that lichens can be used as biomonitors to distinguish urban from industrial polycyclic aromatic hydrocarbons (PAHs). PAHs are atmospheric pollutants originating mainly from incomplete combustion of fuels in vehicles and industry. The occurrence of PAHs in air is a serious health issue in urban areas and industrial areas because some PAHs are carcinogenic. Biomonitoring PAHs with lichens is generally applied for quantification of PAHs. However, the precise sources of PAHs are not well known. Here we use lichen to trace the source of PAHs. PAHs were analyzed in Pyxine subcinerea Stirton, a lichen species collected from twelve sites which vary from urban and industrial to periurban forest area of Haridwar, in the foothills of the Indian Himalayas. Total PAH concentration ranged between 1.25 and 187.3 lg g -1 . Results indicate a clear distinction between urban and industrial PAHs profile, using principal component analysis. Lichen sampled from industrial sites exhibited higher concentrations of two-, five-, and six-ringed PAHs, up to 60% of total PAHs, while samples from urban sites were dominated by fourringed PAHs, predominantly fluoranthene and acenaphthylene. Molecular ratios indicate that combustion was the dominant source of origin of PAHs in industrial area, while urban sites showed mixed origin of PAHs, both pyro-and petrogenic.

“…Although there are a few publications concerning the use of lichens as biomonitors of organic compounds, such as PAHs and PCBs (Villeneuve et al, 1988;Herzig, 1989;Garty, 2000;Owczarek et al, 2001;Guidotti et al, 2003), to our knowledge this is the first regional case-study to use lichens as biomonitors of PCDD/Fs. Thus we hypothesize that, as in previously studies concerning lichens as biomonitors of organic compounds, it will be shown that lichens are suitable biomonitors for estimating atmospheric PCDD/F deposition.…”

“…They have been extensively used to biomonitor a variety of elements, such as sulfur, nitrogen, fluoride, metals, radionuclides, and various organic compounds like PCBs (polychlorinated biphenyls), PAHs (Polycyclic Aromatic Hydrocarbons), and substances from organochloride pesticides (HCHs and HCB) (Villeneuve et al, 1988;Herzig, 1989;Calamari et al, 1991;Garty, 2000;Owczarek et al, 2001;Guidotti et al, 2003). This well-established technique has been widely used in European countries to evaluate atmospheric deposition status since the late 1960s.…”

Abstract. Polychlorodibenzeno-dioxins and polychlorodibenzeno-furans (PCDD/Fs) are considered among the most toxic compounds on earth. The aim of the present study was to evaluate atmospheric PCDD/F deposition and identify the areas with greater deposition of these compounds in an important industrialized and urbanized region of Portugal, using lichens as biomonitors. For this purpose, samples of the lichen Xanthoria parietina were collected at 60 sampling sites, covering urban, industrial, forestry and agriculture areas, and analyzed for PCDD/Fs, sulfur, nitrogen, zinc, iron, chromium, lead, cobalt, nickel, copper, calcium, manganese, magnesium and potassium. The concentrations of PCDD/Fs in lichens were compared with the other elements and related to land-use and population density. The results obtained through the geostatistical interpolations and after principal component analysis have shown that PCDD/F deposition estimated by lichens is greater near industrial and highly populated urban areas. We found that lichens are suitable biomonitors of PCDD/F atmospheric deposition and can contribute to a better knowledge of air quality in a region, enabling identification of critical pollutant deposition areas.
