assessment of air Pollution Tolerance index of some plants to develop vertical gardens near street canyons of a polluted tropical city
Ecotoxicology and Environmental Safety, 2016Co-Authors: Ashutosh Pandey, Mayank Pandey, B D TripathiAbstract:The aim of the present study was to examine Air Pollution Tolerance Index (APTI) of some climber plant species to develop vertical gardens in Varanasi city which has characteristics of tall building and narrow roads. This condition results in street canyon like structure and hinders the vertical dispersal of air pollutants. We have selected 24 climber plant species which are commonly found in of Varanasi city. Chosen plants can be easily grown either in planter boxes or directly in the ground, with a vertical support they can climb on walls to form green walls or vertical garden. Air Pollution Tolerance Index (APTI) of the selected plant species was calculated and plants with higher APTI are recommended for the development of Vertical garden. Highest APTI was noted for Ipomoea palmata (25.39) followed by Aristolochia elegans (23.28), Thunbergia grandiflora (23.14), Quisqualis indica (22.42), and Clerodendrum splendens (22.36). However, lowest APTI value (8.75) was recorded for the species Hemidesmus indicus. Moreover, the linear regression analysis has revealed a high positive correlation between APTI and ascorbic acid content (R2=0.8837) and positive correlation between APTI and Chlorophyll content (R2=0.6687). On the basis of higher APTI values (greater than 17), nine species of climber plants viz. I. palmata, T. grandiflora, C. splendens, A. elegans, Q. indica, Petria volubilis, Antigonon leptopus, Cryptolepis buchuanni and Tinospora cordifolia have been recommended to develop vertical greenery systems in a compact tropical city.

Air Pollution Tolerance Index of climber plant species to develop Vertical Greenery Systems in a polluted tropical city
Landscape and Urban Planning, 2015Co-Authors: Ashutosh Pandey, Mayank Pandey, B D TripathiAbstract:Abstract Urban greenery can provide a cost-effective and eco-friendly technique to help reduce air Pollution in compact urban areas. Urbanization generally replaces natural vegetation with concrete structures. Greenery can be reintroduced into such urban areas by development of vertical greenery systems (VGSs) on building walls. Such plants must be selected based on their air Pollution Tolerance level. Air Pollution Tolerance index (APTI) is one such index which is based on four properties of plant leaves such as ascorbic acid content, leaf extract pH, relative water content and total chlorophyll content. In this study in Varanasi, India, air Pollution was monitored at seven sites to know the air quality status, based on which two sites were selected for evaluating APTI. Twenty eight climber plant species commonly found near a polluted site (site-1) were selected and their APTI was evaluated. APTI of same set of plants were also analyzed at relatively less polluted rural site (site-7) for comparative study. Linear regression analysis has revealed a high positive correlation between APTI a d ascorbic acid content ( R 2 = 0.8676) and positive correlation between APTI and Chlorophyll content ( R 2 = 0.4957). On the basis of higher APTI values (greater than 17), eleven climber species i.e. Ipomoea palmata , Antigonon leptopus , Thunbergia grandiflora , Clerodendrum splendens , Aristolochia elegans , Quisqualis indica , Vernonia elaeagnifolia , Petrea volubilis , Adenocalymma comosum , Cryptolepis buchanani and Jacquemontia violacea have been identified at polluted urban site to develop vertical greenery systems in this compact tropical city.

air Pollution Tolerance index and anticipated performance index of some plant species for development of urban forest
Urban Forestry & Urban Greening, 2015Co-Authors: Ashutosh Kumar Pandey, Mayank Pandey, Ashutosh Mishra, Ssiddhant Mohan Tiwary, B D TripathiAbstract:Abstract Urban forest is a collection of trees growing in urban area. Green plants are well known for their abilities to reduce air and noise Pollution. It is important that plants used for the development of urban forest must be tolerant to air pollutants. There must be some criteria to select tolerant plants for urban forest and for that two indices viz. air Pollution Tolerance index (APTI) and anticipated performance index (API) can be a good tool. In the present study, 29 plant species commonly found in urban area of Varanasi, India, has been evaluated for their APTI and API. Based on these two indices, the most suitable plant species were identified and recommended for development of urban forest in Varanasi for long-term air Pollution abatement. It was revealed that Ficus benghalensis L. and Ficus religiosa would be excellent performers. Similarly Polyalthia longifolia , Ficus glomerata (Roxb.), Anthocephalus indicus and Mangifera indica were estimated to be very good performers. In the similar fashion Cassia fistula L., Drypetes roxburghii , Terminalia arjuna , Psidium guajava L., Millingtonia hortensis and Dalbergia sissoo were estimated to be good performers with respect to anticipated performance index.

Pollution Tolerance and distribution pattern of plants in surrounding area of coal fired industries
Journal of Environmental Biology, 2007Co-Authors: Anil Kumar Dwivedi, B D TripathiAbstract:Higher concentration of SO2 and particulate matters was reported in surrounding areas of coal-fired industries which influences the distribution pattern of plants. Sensitive plant species are abolished from such areas, however, only Pollution tolerant species survive under stress conditions. The present study was designed to investigate the vegetation composition around coal-fired industries i.e. brick industries. To categorise plants as sensitive or resistant air Pollution Tolerance index (APTI) value was calculated. Out of 99 plants studied, Ricinus communis with APTI 81.10 was found to be the most resistant wild plant showing uniform distribution at all the polluted sites. On the other hand, Lepidium sativum with APTI 5.27 was recorded as the most sensitive plant and found to be present only at the less polluted sites.

الجامعة الإسلامية - غزة, 2015Co-Authors: Saleh Mohammed AwajaAbstract:The research was carried out to determine the floristic composition, life form and the most important families of the wild plant species in the industrial area, Beit Hanoun city, Northern Gaza Strip situated in the south Governorates within Palestine. Although. The study area is a small area, the plant species richness and floristic biodiversity is a high in comparison with relevant nearby areas in the Mediterranean region. A total of 100 species vascular plant belonging to 85 genera and 34 families were recorded. Botanical survey and extensive field trips were made in the study area during the period from March to September 2012/ 2013 and the plant identification based on different taxonomic keys. The best represented families were Asteraceae (21%), Poaceae (15%), Solanaceae (6%), Brassicaceae (5%), Caryophyllaceae (5%), and Fabaceae (5%). Therophytes represented by (71%) of the plant species constitute the largest number of the total plant species comparing with other life forms, phanerophytes (12%), hemicryptophytes (9%), chamaephytes (6%) and cryptophytes (2%). The sampling area for the present study was separated into six sites, to be satisfactory to represent the vegetation of the area. Plants were randomly selected from the immediate vicinity of the first five sites, namely Hamooda, Abosaphea, Mansoer, Spong and Medicine factory which designated as experimental site (ES). Al showa station is a site was selected as the control site (CS). 23 plant species were collected from the six different locations of study area. Solanum elaeagnifolium cav., Malva parviflora L, Polygonum equisetiforme Sm., Marrubium vulgare L., Verbascum sinuatum L. found at all sites. Measurements of relative leaf water content (Rwc), total chlorophyll content (TCH), leaf extract PH, ascorbic acid (A.A) and Air Pollution Tolerance Index (APTI) were estimated at all the previous mentioned plant species at the different locations of the study area revealed that the combination of the biochemical and physiological parameters gave a more reliable results than those of individual parameter. The results of air Pollution Tolerance index (APTI) calculated for each plant species studied at different six sites revealed that Polygonum equisetiforme exhibited the highest (APTI) value at all the sites followed by Nicotiana glauca followed by Solanum elaeagnifolium followed by silybum marianum, while the lowest values of (APTI) are recorded in Marrubium vulgare followed Marticaria recutita followed by Chenopodium vulvaria. Therefore, the plants with high and low (APTI) can serve as tolerant and sensitive species respectively

air Pollution induced vegetation stress the air Pollution Tolerance index as a quick tool for city health evaluation
Ecological Indicators, 2020Co-Authors: Vanda Eva Molnar, Edina Simon, Bela Tothmeresz, Sarawut Ninsawat, Szilard SzaboAbstract:Abstract Air Pollution Tolerance Index (APTI) is used to assess how tolerant plant species are of air Pollution; it also serves to identify tolerant plant species that can be useful for Pollution removal. APTI is calculated from parameters that are affected by air pollutants, such as ascorbic acid content, total chlorophyll content, relative water content and pH of leaf extract. In this study we report APTI values of two common tree species (Celtis occidentalis and Tilia sp.) in Debrecen, Hungary. We also ran a meta-analysis to compare APTI values among various global cities and land use types (industrial, roadside and urban) using robust ANOVA. APTI’s relationship with city population and PM10 (particulate matter with aerodynamic diameter smaller than 10 μm) was analysed using regression modelling and Principal Component Analysis. We applied Random Forest Regression for statistical model building. We demonstrated that the Tolerance of tree species is higher in industrial areas and in cities with high Pollution levels than in control areas. We found a strong positive correlation between APTI and the size of cities. The cities showed a separation along the first principal component, which was also correlated with APTI and the size of cities. Our results show that APTI is an efficient tool in air Pollution monitoring and in decision making during urban development and urban greening.
