“…Some of the organisms whose capacity as bioindicators has been demonstrated are epiphytic lichens, which are capable of bioaccumulating contaminants for prolonged periods and above their own physiological needs, thus making them an ideal means to evaluate the presence and bioavailability of speci c contaminants. They could, therefore, become a key tool in pollution studies (Saib et al 2023). Although their use as bioindicators is of the utmost importance, few studies apply them to issues concerning contamination by agrochemicals (Yatawara & Dayananda 2019).…”

“…The large amounts of pollutants released into the atmosphere have a negative impact on air quality, thus making air pollution studies a crucial research area (Parviainen et al, 2019). The decrease in air quality as a result of the increase in atmospheric pollutants has various effects on living organisms, and has become an environmental problem at a global level (Saib et al, 2023). Of these, emissions of air pollutants from road tra c are, along with heavy metals (Cicek et al, 2001), widely recognized as the main sources of air pollution in cities around the world (Fioravanti et al, 2018; Hankey & Marshall 2017).…”

The presence or absence of lichens serves as an indicator of the condition of an ecosystem and the degree to which it is contaminated by various agents, such as agrochemicals and metals. Evaluating the use of lichens as bioindicators of agrochemical contamination could provide a more comprehensive perspective on current contamination levels. Monitoring was, therefore, carried out over a four-month period in two study areas: a well-conserved control area and another treated area surrounded by agricultural crops. Data on the presence and abundance of lichens in each study area were recorded at 10 sampling points, a procedure that was repeated 16 times (every 15 days), and concentrations of heavy metals and “organophosphate” agrochemicals in the lichens collected were measured by means of gas chromatography. Generalized linear mixed models were used to assess abundance and richness, while general linear mixed models were used to attain Shannon diversity and Simpson dominance indices. Moreover, a multivariate analysis was performed in order to compare the lichen communities in both areas. The results indicated differences between the control and treated areas in terms of abundance and Simpson's dominance index, while no differences were found for the richness and diversity models. The PERMANOVA analysis also showed differences between the lichen communities in the two areas. The results also demonstrated that “Canoparmelia caroliniana” bioaccumulated metals in both areas. Finally, the concentrations of agrochemicals were higher in the treated area, and included toxic substances such as Methyl Parathion and Parathion, which are prohibited in Ecuador. In conclusion, the research underscores the importance of lichens as precise indicators of environmental health and contamination by agrochemicals and metals.

“…17 As a result, the abundance of the most sensitive lichen species can be used to evaluate air quality. [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] Lichens exist naturally in many terrestrial habitats, however their absence in urban environments may be due to human influences. In such instances, passive biomonitoring becomes ineffective, and active biomonitoring take its place.…”

Pollutants in the air and heavy metals are regarded as significant contributors to environmental problems. These environmental issues have a wide range of consequences for living organisms. Heavy metals and contaminants have the potential to alter the makeup and flexibility of cellular frameworks, preventing plant and lichen species from absorbing water and nutrients. Lichen thalli can absorb heavy metals through their cell walls. Lichens are more susceptible to environmental stress than other vascular and non-vascular plants. The goal of this research was to find out the levels of air pollution in Kırıkkale and to generate a city air pollution image using Pseudevernia furfuracea (L.) Zopf as bioindicator organisms. In November 2002, lichen specimens were taken from an uncontaminated area in the Yapraklı Mountains in Çankırı city and transplanted to 11 various locations in Kırıkkale. Lichen samples were collected twice after 3 and 6 months of exposure. Inductively Coupled Plasma (ICP) spectrometry was used to measure the heavy metals, Cu, Cd, Mn, Ni, Pb, and Zn contents. The chlorophyll a and b concentrations were measured and also the chlorophyll a+b, a/b, and b/a ratios were calculated as well. According to the findings of P. furfuracea heavy metal analyses, contents of heavy metals were found to be in first period in range of 0.23–0.45 μg g−1, 0,013–0,020 μg g−1, 1,83–2,61 μg g−1, 0,21–0,59 μg g−1,0.37–0,80 μg g−1, and 0,17–2,10 μg g−1, in second period in range of 0,31-0,77 μg g−1,0,014-0,026 μg g−1 ,1,97-3,06 μg g−1 ,0,24-0,63 μg g−1 , 0,45-1,25 μg g−1 and 0,23-6,74 μg g−1 for Cu, Cd, Mn, Ni, Pb, and Zn. Among the reasons for the high values, traffic, autumn-winter heating activities and industrial activities can be mentioned. At 4th and 8th stations with heavy metal accumulation, chlorophyll degradation (0,22 and 0,18 ugr/ml) had started to be observed. These findings showed that P. furfuracea have a high potential for biomonitoring heavy metals in air pollution researches.

“…The accumulation of heavy metals in lichens may differ among species, as it is greatly influenced by land use gradients within a particular habitat (Bozkurt, 2017;Demková et al, 2017a, b;Parviainen et al, 2019;Popova, 2019;Vitali et al, 2019;Işik and Yildiz, 2022;Mohamed et al, 2023;Saib et al, 2023). Among the lichen-rich regions in the Indian subcontinent, the temperate habitats of the Himalayas stand out (Upreti, 1998).…”

Aim: The aim of this research was to identify a suitable lichen species as a bio-indicator for heavy metals in the Himalayan habitats. Methodology: The study was conducted in a sacred grove located in Western Nepal. The grove was situated alongside the busy Mahakali National highway. Lichen samples were collected from different areas of the grove, ranging from the edge adjacent to the highway to the center. Standard protocols were employed to identify the collected lichen species. The heavy metal content in the samples were analyzed by subjecting them to acid digestion followed by AAS estimation. Results: Three lichen species were discovered: Bulbothrix meizospora, Parmotrema tinctorum, and Pyxine berteriana. Pyxine berteriana was collected near the highway, while Bulbothrix meizospora and Parmotrema tinctorum were collected away from it. The heavy metal bioaccumulation pattern observed was as follows: Fe>Al>Mg>Zn>Cu>Pb>Mn>Ni>Cd>Cr. Notably, Pyxine berteriana exhibited the highest metal concentrations among the three species. Interpretation: Based on the findings, it can be concluded that the Physcioid lichen Pyxine berteriana is the most resilient species in the region and can serve as an appropriate bio-indicator for studying the deposition of heavy metals in the ambient air. Key words: Physcioid lichens, Pyxine berteriana, Parmotrema tinctorum, Lichens, Sacred Grove
