The current study was done to examine the impact of environmental pollution on morphology and anatomy of leaf of Ricinus communis L. of Kathmandu. The comparative study was done between the plants of high polluted sites i.e Ringroad sides and less polluted sites i.e Raniban forest of Kathmandu. The plants from both sites showed visible morphological and anatomical changes in leaves. These both study sites were found with similar soil factors and climatic factors. Reductions in some morphological and anatomical features were observed in leaves growing in highly polluted site. Reduction in leaf area, petiole length, thickness of palisade layer and thickness of spongy parenchyma was noticed in the leaves from highly polluted sites of Kathmandu. Other morphological and anatomical features such as leaf dry mass content, stomata frequency, thickness of cuticle and size of epidermal cells were noticed to be increased in leaves from highly polluted sites.

“…Since plants are stationary and are continuously exposed to chemical pollutants from the surrounding atmosphere, air pollution injury to plants is proportional to the intensity of the pollution. The adverse effects of air pollutants on different plant species have been reported by several workers (Kousar et al, 1999;Mashitha and Pise, 2001;Raina and Sharma, 2003;Raina and Aggarwal, 2004;Mandal, 2006;Joshi & Bora, 2011;Senthilkumar and Paulsamy, 2011;Thambavani and Sabitha, 2011;Gharge and Menon, 2012;Nugraharani et al, 2012 andRadhapriya et al, 2012). The sensitivity towards air pollution varies across the plant community and some being 'tolerant' showing no or minimal symptoms even if the air pollutants increase.…”

The air pollution tolerance indices (APTI) of four plant species: Ficus religiosa, Polyalthia longifolia, Pterospernum acerifolium and Thevetia peruviana growing along roadsides at polluted site (Satwari-Bikram Chowk road) in Jammu city has been worked out and compared with the plants growing at the reference location (New University Campus) to categorize plants as sensitive or resistant. The plants were analysed for leaf relative water content (RWC), ascorbic acid content (AA), total leaf chlorophyll (T Ch) and leaf extract pH to compute the APTI values which indicated that all plants belong to sensitive category as per the index range given by Gaikwad et al. (2006). The values of all the studied biochemical parameters and APTI has been observed to decline in the plants growing at polluted sites in comparison to plants growing at reference site. However, among the plant species growing at polluted site, Ficus religiosa has been observed to be comparatively more tolerant against air pollutants with a maximum APTI value (4.76±0.16) whereas Pterospernum acerifolium is more sensitive to air pollutants with minimum APTI value (1.65±0.19). The order of tolerance among these plants has been observed to be: Ficus religiosa> Polyalthia longifolia> Thevetia peruviana> Pterospernum acerifolium. The result also indicated that combining variety of these parameters gave a more reliable result than those of individual parameter.

“…Reduction of leaf mesophyll, palisade parenchyma and upper and lower epidermis in Tanacetum vulgare was also observed by Stevovi et al [31]. Stomatal abnormality (clogging and reduction of size) and reduction of the epidermis are occurred due to high deposition of dust particles or increased concentrations of toxic gasses such as CO2 and SO2, which is a symptom of air pollution [32].…”

Objective: Air pollution is one of the most severe environmental problems of developing cities which adversely affects both plant and human life. However, roadside plants in the urban locations help in reducing the pollution level from the air through foliar surface and act as pollution sink. In this work, an attempt was made to understand the impact of air pollution on urban roadside plants which act as bio indicator. Methods:A study was conducted to check the impact of urbanization on air pollution by analyzing anatomical and biochemical aspects of Thevetia peruviana L. For anatomical analysis, the transverse sections of leaves were observed under a microscope; whereas for biochemical analysis, the estimation of chlorophyll, carotenoid and protein were determined by spectrophotometric methods. On the other hand, antioxidant enzyme assays, as well as specific activity staining, were performed to study the antioxidant potential. To investigate the antioxidant activity of the leaf extracts, an assay for catalase (CAT), guaiacol peroxidase (GPX) and superoxide dismutase (SOD) were performed. Isoforms of CAT, GPX and SOD were separated using native polyacrylamide gel electrophoresis (PAGE) and their activities were analyzed.Results: Analysis of data revealed that the anatomical disturbances significantly occurred in exposed plants of various sites. Among biochemical parameters, photosynthetic pigments such as chlorophyll a, chlorophyll b, total chlorophyll and carotenoid content were found to be decreased. A maximum (7.65±0.51, 3.78±0.56,11.43±0.91, 5.63±0.55 mg/g, respectively) decrement was noticed in leaves of the Pokhariput plant in comparison to Khorda NH5 (19.44±1.08, 10.12±1.03, 29.56±2.32, 10.22±1.21 mg/g, respectively) which is taken as control one. To determine the effect of air pollution on proteins, leaf extracts were analyzed by the Lowry method and sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The substantial decrement of total protein and alteration in polypeptides were noticed in polluted sites. Meanwhile, the enhancement of antioxidant enzyme activities such as CAT, GPX and SOD were also detected. Conclusion:The increment of antioxidant enzymes and alteration of proteins, suggesting the activation of defensive mechanisms in selected plants under air pollution stress and also the plants made physiological and biochemical adjustments to overcome the oxidative damage.
