And Control

With rapid increase in urbanization followed by industrialization compounded due to ever-exploding population in the past few decades there is a steep rise in contamination of one of the most vital abiotic factors of the environment i.e., the air. In these circumstances, the clean and green measures to monitor and control air pollution have become inevitable. Air Pollution Tolerance Index (APTI) is one such index for indicating the extent of the plants to withstand air pollution. This includes analysis of physiological and biochemical parameters like total chlorophyll content, ascorbic acid content, pH of the leaf extract and relative water content of the leaves. In this study, the plants selected are mature tree species like Polyalthia longifolia, Putranjiva roxburghii, Alstonia scholaris, Delonix regia and Peltophorum pterocarpum from Mumbai and its surrounding regions. According to the Air Pollution Tolerance Index (APTI) values, plants can be classified as tolerant, intermediate, sensitive and highly sensitive. The tolerance of the plants studied in the decreasing order is as follows P. roxburghii > P. pterocarpum > D. regia > P. longifolia > A. scholaris. Species selected on the basis of their APTI values can then be used as bio-indicators of air pollution and in its mitigation for green belt development in urban areas.

Air pollution due to huge number of vehicles emitting toxic gas poisons both living environment affecting fauna and flora. Road side plants are affected mostly by pollution as they are primary acceptors and gets reflected in terms of tolerance and sensitivity to pollution. Hence, the present work was designed to study the air pollution tolerance (APTI) using biochemical parameters and anticipated performance index (API) of the plants collected near seven different locations. Among the plants assessed, all plants selected does not show much difference in ascorbic acid, total chlorophyll, pH, relative water content, but that slight difference exhibited variations in air pollution tolerance index. Pongamia pinnata (33.16), Ficus religiosa (34.05) Near Asian rubber Industry, Kandampatty Byepass, Salem was found to be a tolerant species, Polyalthia longifolia (8.21) as very sensitive in plants studied Near KMB Granites Pvt. Ltd. Kottagoundampatty, Salem, and the rest was found to be moderately tolerent. Since, the studied plants show lesser surface area, the amount of dust collected was also less, which might be due to the climatic condition prevailed at that time of sample collection. Likewise, the API was found to be excellent in Yercaud lake view and very good in study area Duroflex company, Karimangalam, Dharmapuri, poor in study area Thanithotty Quarry, Salem as well as in KMB granites Pvt.Ltd. and good for the remaining three locations. So, the sensitive plants has to be protected that are located in these sites to reduce the pollution load.

Air pollution gives negative effects to humans as well as to plants which are exposed all throughout the day in these pollutants. Assessment of plants' response to air pollutants may serve as a fundamental method in terms of environmental monitoring and management. Sensitive group of plants can serve as an indicator of air quality while the tolerant ones can be sinks. TheAir Pollution Tolerance Index (APTI) of selected plant species in Puerto Princesa City, namely: Bougainvillea (Bougainvillea spectabilis), Santan (Ixoracoccinea), Fire Tree (Delonixregia), Golden Bush (Durantarepens), and Acacia tree (Samaneasaman)were evaluatedusing relative water content, ascorbic acid content, leaf extract pH, and total leaf chlorophyll content.It was found out that B. spectabiliswas the most tolerant species, followed by S. samanwhile D. regiahas an intermediate index. D. repensand I. coccineaon the other hand were found to be sensitive plant species. Plants with high APTI values are the tolerant ones and are recommended to be planted in urban areas to absorb and off certain harmful gaseous pollutants while the sensitive ones have the potential to serve as bio-indicators for evaluation and monitoring.

Air Pollution Tolerance Index is used to find out the level of air pollution in any area with the help of plants. Plants are categorized as sensitive, intermediate and tolerant based on their APTI values. The present study examines the Air Pollution Tolerance Index of selected plant species in Bikaner city. The APTI of various plants have been computed with the values obtained by analysis of biochemical parameters such as pH of leaf extract, ascorbic acid content (AAC), total leaf chlorophyll content (TLC) and leaf relative water content (RWC). It was found that plant species Khejri (Prosopis cineraria), Neem (Azadiracta indica), Babul (Acacia nilotica), Ber (Ziziphus nummularia), Aak (Calotropis procera) and Peepal (Ficus religiosa) showed APTI values in the range of 30 to 100 which are tolerant to air pollution. Datura stramonium was the only species which falls under the intermediate category due to its APTI value of 21.5. It is recommended that these plants can be grown on national highways to combat air pollution in arid areas. Such plants can be used in the development of green belt.

Roadside Plants

This paper describes air pollution tolerance among roadside plants exposed to varying degrees of vehicular pollutants. Evaluation of air pollution tolerance index (APTI) of 10 selected wild plant species was carried out to assess their response to ambient levels of air pollutants along the busy roadways of Ahemadnagar Four parameters namely total chlorophyll, ascorbic acid, pH of leaf extract and relative water content were determined and computed together to signify air pollution tolerance index (APTI) of plants. The observed significant reduction in total chlorophyll, ascorbic acid and relative water content showed inverse relationship with traffic density. Similarly, pH of leaf extract followed an exponential decrease with increase in traffic density and drifted towards acidic range. Comparison of APTI values from control to polluted sites revealed maximum reduction in Bougainvillea spectabilis while least change was noted in Peltophorum pterocarpum. Among the plants studied maximum net per cent reduction of APTI over control was seen in Bougainvillea spectabilis and Ageratum conyzoides and are considered to be sensitive species. While Peltophorum pterocarpum and Portulaca oleraceae are tolerant species since they have shown least per cent reduction in APTI.

The Impact

Air pollution tolerance index (APTI) is used by landscapers to select plant species tolerant to air pollution. The present study evaluated APTI for selected ten common plant species, which were fumigated with 40 ppb sulfur dioxide (SO2) gas for 210 days. The APTI is used by landscapers to select plant species tolerant to air pollution. In order to develop the usefulness of plants as indicators requires an appropriate selection of plant species, which is of utmost importance in specific situations. Four biochemical parameters, including ascorbic acid content, leaf extract pH, total leaf chlorophyll, and leaf relative water content were used to develop an APTI. The results showed that plants have the potential to serve as excellent quantitative and qualitative indices of pollution. Since biomonitoring of plants is an important tool by which to evaluate the impact of air pollution on plants, Diospyros maritime is a good selection as an index of SO2 pollution. The order of tolerance in SO2 as Diospyros maritime > Diospyros discolor > Decusscarpus nagi > Cerbera manghas > Delonix regia > Melia azedarach > Machilus zuihoensis > Ficus sepitca > Erythrina variegate > Messerschmidia argentea.

Trees And Shrubs

Urban green space is a collection of trees and shrubs 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 landscaping must be tolerant to air pollutants. There must be some criteria to select tolerant plants for urban landscaping design and for that two indices viz. Air Pollution Tolerance Index (APTI) and carbon sequestration can be a good tool. Thus this study was carried out to assess the efficiency of urban trees (Tabebuia rosea, Polyalthia longifolia, Delonix regia and Raphia farinifera) and shrubs (Ficus spp) to tolerate air pollution and potential for carbon sequestration in Akure, Ondo State, Nigeria in 2015. The sites were sampled from Akure City Major Road, from Oloko Junction to Oba-Ile. The plant species identified at the sample area were Ficus spp, Tabebuia rosea, Polyalthia longifolia, Delonix regia and Raphia farinifera. The assessment of the ascorbic acid, pH, relative water content and total chlorophyll content of the leaves of the identified plant species was done to determine the APTI. The APTI of the plant ranged from 5.11 to 9.31 with Tabebuia rosea having the highest value which indicates it's high tolerance of air pollutants from the assessment and Raffia farinifera with the lowest value and least tolerant. The biomass of the trees species were estimated for the quantification of the amount of carbon sequestered and the absorbed CO2 in the plant. Tabebuia rosea also had the highest carbon sequestered (10,074 kg) and Delonix regia having the lowest of 4,702.50 kg.

This study was designed to monitor the ambient air pollution in several sites within Baghdad City of Iraq. The readings started from May 2016 to April 2017. The highest concentration of sulfur dioxide (SO2) was 2.28 ppmm-3 while nitrogen dioxide (NO2) was 3.68 ppmm-3 and suspended particulate matter was 585.1 ?gm-3. This study also included estimating the value of the air pollution tolerance index (APTI) for four plant's species Olea europaea L., Ziziphus spina-Christi (L.) Desf, Albizia lebbeck(L.) Benth. and Eucalyptus camaldulensis Dehnh. Were cultivated on the road sides. The study includes four biochemical parameters, total chlorophyll content, ascorbic acid content, pH and relative water content of plant leaves. The results show that combining variety of these parameters give more certain results than those of single parameter. These four estimated parameters have positive correlation with each other and with the values of the air pollution tolerance index in all plants studied.
