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.
Evaluation of air pollution tolerance index of tree species of Bikaner city (Rajasthan)
The holistic approach to environment, 2023
The air pollution tolerance index (APTI) is one of the modern tools for assessing the impacts of air pollutants on plant physiology. The value of APTI is different for different plant species. Plants with higher values of APTI are tolerant and act as a sink due to their bioaccumulation ability for air pollutants. Hence, they can be planted to establish green belts in areas with severe air pollution, especially in industrial zones. The present investigation was carried out to assess the APTI values of top twenty urban tree species of the Bikaner city of NorthWestern Rajasthan. The leaf samples were taken from selected roadside trees distributed in the residential, commercial and industrial zones of the city. On the basis of APTI values, it was observed that Leucaena leucocephala (23.41), Eucalyptus camaldulensis (21.87) and Cassia siamea (21.39) had an APTI value above 20 and they are therefore classified as tolerant species. Similarly, Pongamia pinnata (9.48) showed APTI under 10, therefore it falls into the sensitive category. 80 % of the total species in the studied area are categorized as a moderately sensitive category. There were no plant species in very sensitive (APTI < 1) and very tolerant (APTI > 30) category.
Plants are universal sink of carbon dioxide. Plantation of species along any road helps to trap air polluting dust and carbon dioxide. The plants are also negatively affected by the dust and gaseous emissions from vehicles. Because of industrialization in the Sambalpur region, the number of vehicles passing through National Highway-6 has grown significantly. This has been the root cause of high level air pollution. In response to this, a study was undertaken to evaluate the air pollutant tolerance level of some tree species present along the NH-6 between Ainthapali to Remed of Sambalpur township using Air Pollution Tolerance Index (APTI) approach. The aspects covered in this work are i) Identification and selection of plant species, ii) Analysis of biochemical parameters like total chlorophyll content, leaf extract pH, relative water content, ascorbic acid of selected species and estimation of air pollution tolerance index values for these species, iii) Evaluation of the Dust accumulating capacity of the selected tree species and its relationship with other morphological parameters, iv) Evaluation of relationship between plants morphological parameters, Dust accumulating capacity and APTI. Three different species viz. Tectona grandis L.f., Polyalthia longifolia (Sonn.) Thw. and Ficus religiosa L. were studied at three sites such as Ainthapali (Site-1), Bareipalli (Site-2) and Remed (Site-3). Relative water content (RWC), Hydrogen ion Concentration of leaf extracts (pH), Total Chlorophyll content of leaf (TCH) , Ascorbic acid content of leaf (AA) were estimated. The petiole length, Leaf area and inter-node lengths were also measured. The dust accumulation potentials of three species were determined. Correlation and regression analysis between different parameters were carried out. The species Tectona Grandis is highly tolerant to air pollution with average APTI values ranging from 7.13 to 10.33. The established decreasing order for grades is Tectona grandis (6) > Polyalthia longifolia (5) > Ficus religiosa (3). The Dust accumulation potential values are highly correlatable with APTI.
Air Pollution Tolerance Index of Some Trees Species from the Industrial area of Tarapur
To evaluate the susceptibility of plants growing in the industrial area of Tarapur, Maharashtra, Air pollution tolerance index (APTI) was determined for 30 plants species by calculating Ascorbic acid content, Leaf-extract pH, Total chlorophyll content and Relative water content and computing together in a formula. The result showed the order of tolerant species as Putranjiva roxburghii >Mangifera indica >Ficus racemosa >Ficus hispida >Morinda citrifolia and the order of sensitive species as Nyctanthes arbor-tristis >Bauhinia purpurea> Peltophorum pterocarpum>Psidium guajava> Morinda pubescens. Air pollution tolerance index (APTI) serves as a reliable technique in qualifying plants as tolerant and sensitive species in regard to air pollution. Tolerant species serve as sink of air pollutants and thus can help in abatement of air pollutants to some extent if planted in and around industrial vicinity and along traffic islands.

Air Pollution Tolerance Index (APTI) is used by landscapers to select plant species tolerant to air pollution. To develop the usefulness of plants as bioindicators requires an appropriate selection of plant species which entail an utmost importance for a particular situation. Four physiological and biochemical parameters including leaf relative water content (RWC), ascorbic acid (AA) content, total leaf chlorophyll (TCh) and leaf extract pH were used to develop an APTI. The present study was designed to categorise trees commonly used as roadside plantations, as sensitive or resistant based on their air pollution tolerance index (APTI) values. The study area selected for the same was the educational hub of Gujarat State i.e. Vidyanagar. The seasonal variations in the APTI values of the selected tree species were studied.

Evaluation of air pollution tolerance index of trees
To develop the usefulness of plants as bio indicators requires an appropriate selection of plant species which entail a highly important for a particular situation. The present study was undertaken to evaluate air pollution tolerance index (APTI) of five different plant species around City area and Navsari Agricultural University campus (Control). Among the trees in the selected area Cassia fistula depicted highest APTI value as compared to other species followed by Saraca asoca and Sizygium cumini and proved to be tolerant variety in the city area as per the APTI value. However, Tectona grandis and Terminalia catapa found to be intermediate sensitivity for the polluted site (City area). Hence, it is recommended to plant S. asoca, S. cumini and C. fistula trees in city / industrial area to cope the environmental problem. The study also suggests that performance index might be very useful in the selection of appropriate species which can be expected to perform well for the developmen...

Air pollution is one of the severe problem world is facing today. It deteriorates ecological condition and can be defined as fluctuation in any atmospheric constituent from the value that would have existed without human activity. In the present study, Air pollution tolerance index was calculated for six plant species (Citrus limon, Eucalyptus sp., Ficus religosa, Mangifera indica, Phyllanthus emblica, and Polyalthia longifolia) growing at five sites in and around Kanpur city (Dada Nagar area, Barra Bypass area, Panki area, IIT Campus area, Sachendi village). It has used four physiological and biochemical parameters like relative water content, ascorbic acid content, chlorophyll content, and pH to compute the APTI values. Eucalyptus globus exhibited the highest degree of tolerance at all the sites, followed by Ficus religiosa,
A comparative study for air pollution tolerance index of some terrestrial plant species
Although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. In the present study, Air pollution tolerance index was calculated for various plant species growing at two sites Nagal village at Sahastradhara Road and the Clock Tower (the experimental site) of Dehradun city, India. The leaf samples were collected from 7 commonly present tree species. The results showed significant effects of various air pollutants on the vegetation in terms of four biochemical parameters analysed. Four physiological and biochemical parameters, which are leaf relative water content, Ascorbic acid content, total leaf chlorophyll content and leaf extract pH were used to compute the air pollution tolerance index values. Statistically significant difference was observed between control and experimental group for Ascorbic acid, t(6)=-4.848,p=.003. Paired t test for air pollution tolerance index between the two groups showed a statistically significant difference, t (6) = -4.548, p=.004. On the basis of air pollution tolerance index values for above mentioned seven tree species, Eucalyptus globus exhibited the highest degree of tolerance at all the sites followed by Ficus religiosa > Mangifera indica > Polyalthia longifolia > Phyllanthus emblica > Citrus limon > Lantana camara.
Assessment for Variation of Air Pollution Tolerance Index of Selected Plants in Bengaluru Urban
To develop the usefulness of Caesalpinia pulcherrima and Catharanthus roseus plants as bioindicators, which entail an utmost importance for a particular situation. This study focuses on the assessment of air pollution tolerance index (APTI) of two selected plant species commonly found along roadsides in Bengaluru, India. The plant species selected for the study were Caesalpinia pulcherrima and Catharanthus roseus. The plants were evaluated in terms of APTI by analyzing four different biochemical parameters: Leaf relative water content (RWC), Ascorbic acid content (AA), Total leaf chlorophyll (TCh), and pH of leaf extract. Based on APTI Caesalpinia pulcherrima was found to be more tolerant compared to Catharanthus roseus. Species with lower APTI value are considered sensitive species, which can be used as a biological indicator for further monitoring of air quality. Species with higher APTI value are tolerant species and thus, can be planted for pollution abatement in order to control and reduce environmental pollution.
