Air pollution tolerance index (APTI) was calculated for various plant species growing in industrial area of Orai. The leaf samples collected from 24 tree species in the industrial area were used to determine their Air Pollution Tolerance Index (APTI) by calculating the ascorbic acid, chlorophyll, pH and relative water contents. The APTI values of less than 16 are reported in 19 species and they can be used as indicators of air pollution. The species Ficus religiosa (24.92), Zizyphus jujuba (21.84), Phyllanthus emblica (17.40), Cassia fistula (17.67) and Tamarindus indica (16.96) showed their moderate response by changing their biochemical contents and were identified as moderately tolerant to air pollution.

The impact of air pollutants on the biochemical characters of the selected plant species from industrial and urban areas was studied by calculating ascorbic acid, total chlorophyll, leaf extract pH and relative water content from leaf tissues. The air pollution tolerance index (APTI) values of the selected plants of different study areas revealed that the APTI values of the plants at the College Farm recorded low compared to Arcot and Ranipet transporation and industrial areas. Among the selected plant species, higher APTI values were recorded from the industrial and urban areas. when compared to areas free from industries and transport. The four selected plant species <italic>viz</italic>. <italic>Neerium oleander, Tamarindus indicus, Azardirecta indica</italic> and <italic>Pungamia pinnata, Neerium oleander</italic> recorded higher APTI values from the industrial and transportation that revealed more tolerance than the other selected plants.The statistical results revealed that Arcot was more polluted compared to Ranipet, and the college farm recorded least polluted due to less exposure to industries, transport and urbanization.

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.

Air Pollution Tolerance Index

Industrialization is an important aspect of a growing economy. However, rapid industrialization has caused many serious impacts on the environment. One such impact is the deteriorating air quality, especially around industries. It is said that afforestation is the best and simplest way for improving the air quality. Also, trees and plants have been increasingly used as filters for dust particles around the home, traffic roads, etc. In scientific studies, it has also been found that trees and plant leaves can be used to assess the ambient air quality by an index called the Air pollution tolerance index. A literature search has been done on the scientific database like Sciencedirect and Researchgate to review the existing knowledge of Air pollution tolerance index and to find the tolerant and sensitive species based on it so that these species can be selectively planted to assess the ambient air quality and also to develop a better green belt around refineries and industries in Assam. The study has reviewed the linkage of the impact of air pollution on leaves of plants and trees through scientific evidence. Through such scientific reviews, the most tolerant species of trees and plants were chosen with the condition that it can grow under the climatic condition of Assam. The recommendation and suggestions of tolerant tree and plant species can be used for specific species plantations for developing green belts around refineries and industries in Assam. The recommendation of sensitive species can be used for monitoring ambient air quality with reference to other standard procedures.

Polyalthia Longifolia

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.

This study reports a combination of two indices, air pollution tolerance index (APTI) and anticipated performance index (API) as viable tools for selecting suitable plants for pollution abatement program. Leaf samples of 6 plant species; Mangifera indica, Araucaria heterophylla, Elaeis guineensis, Syzygium malaccense, Acacia auriculiformis, and Chrysophyllum albidium were collected from an industrial and academic areas at Ado-Odo, Ota, Nigeria; during the dry season of January to March 2018. Biochemical parameters; leaf-pH, relative leaf water content, total chlorophyll content, and ascorbic acid content were analyzed to compute the APTI values. Combined APTI, botanical and socioeconomic indices were graded to evaluate the API of the different plant species. The APTI for the species ranged between 4.79 and 10.7, ideal for sensitive species category (APTI < 11), and the plants are classified as bio indicators of air pollution. The API indicates Mangifera indica and Syzygium malaccense (API = 4) as good performers while Chrysophyllum albidum is a moderate performer (API = 3). The three tree species were identified as suitable green belt plants and thus valuable additions to the green belt development plant list in tropical Africa.

Evaluation And Monitoring

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.
