Physiochemical Alterations and Air Pollution Tolerance Index in Ficus religiosa L. Planted Along Polluted Roadsides of Lahore City

Air pollution is among the nastiest form of pollutions causing vexation over the globe. The recent situation of eco-toxicity showed that whole planet is facing this misery explicitly or implicitly. The essence of this enigma is rapid urbanization and industrialization. Global developmental activities, deforestation, uncontrolled industrial emission and increase in vehicular load made this environment unfit for healthy life. This research work explored the effect of air pollution on Physiochemical attributes of Ficus religiosa L. planted along the polluted roadsides of Lahore city. Leaf area, ascorbic acid contents (AAC), total chlorophyll content (TCh), pH of leaf extract, relative water contents (RWC), and dust accumulation on leaves surface were measured using standard methods. Air Pollution Tolerance Index was computed, and the results were compared with the control plants from Changa Manga forest, 70 Km away from Lahore city in cleaner locality. Several Physiochemical alterations in F. religiosa growing in polluted arias were observed, including average leaf area (1367�14.25mm2), AAC (0.68� 0.021 mg/g), TCh (8.50� 0.017) pH of leaf extract (7.17�0.018), RWC (92.5�0.076 %), and dust accumulation on leaves surface (0.0716�0.00063 mg/cm2) compare to control. The recorded average APTI value (10.32�0.023) was higher in the plants grown along the polluted roads compared to controls (9.39�0.012). It is concluded from the results that air pollution tolerance level of F. religiosa was higher along the polluted roads of Lahore. It depicts that they are considerably affected the prevailing air pollution.

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.

Air Pollution Tolerance Index

Objective: Air pollution is one of the major global tribulations in many developing cities around the world. Addressing this sort of pollution is more intricate than other ecological challenges. As pollution is an upcoming issue, we aimed at assessing the air pollution tolerant plants from roadside exposed to vehicular air pollution from two different locations in Thane city.Methods: In the present study, commonly available ten roadside tree species selected from polluted and control area, and their air pollution tolerance index (APTI) determined in Thane city. The biochemical parameters viz. pH, ascorbic acid, total chlorophyll, relative water content (RWC) were considered to calculate APTI by using standard method.Results: The study shows that the control site has more APTI than the polluted site. The APTI observed minimum in Tectona grandis 5.2±0.3247 and maximum in Azadirachta indica 13.5±0.4404. Reduction in APTI at polluted site shows that Alstonia scholaris (6.6%), Tamarindus indica (8.8%) and Azadirachta indica (10.3%) were the most tolerant tree species, while Tectona grandis (47.5%), Acacia nilotica (27.4%) and Cassia fistula (20.7%) were more sensitive tree species. The results showed the order of tolerance (% difference in APTI) as Alstonia scholaris (6.6%)>Tamarindus indica (8.8%)>Azadirachta indica (10.3%)>Moringa pterygosperma (11.9%)>Mangifera indica (13.9%)>Bahunia variegate (14.3%)>Annona squamosa (18.7%)>Cassia fistula (20.7%)>Acacia nilotica (27.4%)>Tectona grandis (47.5%).Conclusion: Tolerant trees species can serve as a sink, and sensitive tree species can act as an indicator for air pollution mitigation. Thus, this study provides useful insights for selecting tolerant species for future planning and Greenbelt development in urban areas.

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.
