“…The meticulous analysis of total heavy metal load, ΣM10, revealed Pyxine berteriana to exhibit the highest level of metal accumulation, followed by Parmotrema tinctorum and Bulbothrix meizospora. These findings consistently align with previous studies conducted by (Upreti, 2014;Singh et al, 2019;Daimari et al, 2020;Banerjee et al, 2023;Thakur et al, 2023), thereby reinforcing their validity and reliability. The remarkable tolerance demonstrated by Physcioid lichens, as confirmed by multiple studies across various Himalayan habitats Shukla and (Upreti, 2007a,b); Shukla et al, 2012;2013;Ramić et al, 2019), underscores their resilience in the face of heavy metal exposure.…”

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

Lichens are (Permotrema parlatum) a symbiotic association of algae and fungus belonging to the family Parmeliaceae. Some of lichen species are consumable and used as an active ingredient for preparation exotic spices as well as folklore medicine to cure different kind of ailments. A specimen of lichen was collected from Munner in Kerala State of South India for its chemical profiling. Chemical analyses of diethyl extract of the defatted lichen led to the isolation of six phenols 1‐6 with variation of relative abundance. Amongst them, the relative abundance of compound 3 was maximum (1% of crude extract) and it was identified as atranorin. The structures of known compounds were identified in comparison with their 1H & 13C NMR and mass data with published values available in literature. In vitro, bioassay of anti‐proliferative activity of these compounds has been conducted against various human cancer cell lines in comparison with paclitaxel as control using SRB assay.

“…Various studies have been conducted in these areas to assess soil and vegetable contamination [10,11]. Daimari et al (2020) assessed trace metal air pollutants in urban, peri-urban, and rural areas on the Brahmaputra Valley plain and found that metals related to automobiles were accumulated in greater volume in samples from peri-urban locations [12]. For example, Chen et al (2018b) and Li et al (2015) discovered that Pb and Cd contents in vegetables were 0.04-0.72 mg kg −1 and 0.02-0.63 mg kg −1 , respectively, which exceeded the national standards (GB2762-2017) [13,14].…”

Leafy vegetables cultivated in kitchen gardens and suburban areas often accumulate excessive amounts of heavy metals and pose a threat to human health. For this reason, plenty of studies have focused on low accumulation variety screening. However, identifying specific leafy vegetable varieties according to the foliar uptake of air pollution remains to be explored (despite foliar uptake being an important pathway for heavy-metal accumulation). Therefore, in this study, the lead (Pb) and cadmium (Cd) contents, leaf morphology, and particle matter contents were analyzed in a micro-area experiment using 20 common vegetables. The results show that the Pb content in leaves ranged from 0.70 to 3.86 mg kg−1, and the Cd content ranged from 0.21 to 0.99 mg kg−1. Atmospheric particles were clearly scattered on the leaf surface, and the particles were smaller than the stomata. Considering the Pb and Cd contents in the leaves and roots, stomata width-to-length ratio, leaf area size, enrichment factor, and translocation factor, Yidianhongxiancai, Qingxiancai, Baiyuanyexiancai, Nanjingjiangengbai and Sijixiaobaicai were recommended for planting in kitchen gardens and suburban areas as they have low accumulation characteristics. Identifying the influencing factors in the accumulation of heavy metals in vegetables through foliar uptake is important to help plant physiologists/environmentalists/policy makers to select suitable varieties for planting in air-polluted areas and thus reduce their threat to human health.
