Industrialization and population growth are the important factors for the deterioration of air quality in the current scenario. Air pollution monitoring using plants as bioindicators is the best and cheapest way. Oxidative stress induced on plants due to air pollution can be studied using antioxidant peroxidase enzyme activity. The present study aims at the comparative assessment of peroxidase activity of twelve plant species from the Chembur industrial area and less polluted zone of similar ecological conditions for two years. The peroxidase activity was determined using the spectrophotometric method. The observations based on the current investigation revealed a rise in the peroxidase activity of twelve plant species of the industrial zone as compared to the less polluted zone. It may indicate an increase in the resistant capacity of all experimental samples toward the oxidative stress caused due to air pollution. Plant species like Pithecellobium dulce (Roxb.) Benth, Ricinus communis L., Leucaena leucocephala (Lam.) de Wit., Albizia saman (Jacq.) Merr, Thespesia populnea (L.) Sol. ex. Correa, Polyalthia longifolia (Sonn.) Thwaites, Prosopis juliflora (SW.) DC., Terminalia catappa L. showed higher peroxidase activity values and hence may be used as bioindicators. Thespesia populnea (L.) Sol. ex. Correa, Polyalthia longifolia (Sonn.) Thwaites and Terminalia catappa L. being evergreen plants may be planted in good numbers in the Chembur industrial area. It may act as a primary step to ameliorate the industrial air pollution in the Chembur industrial zone by enhancing the green zone. This kind of investigation with other factors may help us to sustain our mother nature for future generations.

The rapid development in urban and industrial areas has risen the air pollution problem for a few decades. Plants leaves can maintain their essential mineral content even under the air pollution stress and can survive for a longer period. Aiming at the current issue of air pollution, the present study was carried out to determine heavy metal and essential element concentration present in twelve landscape plant species collected from the Chembur industrial area of Mumbai. Heavy metal accumulation in leaves exhibits an impact on plant metabolic processes. The highest cobalt concentration (3.07 ppm) was reported by Prosopis juliflora (Sw.) DC. in the rainy season. The highest chromium concentration was reported by Calotropis gigantea (L.) Dryand (11.38 ppm) in the summer season. Calcium mineral content was found to be maximum for Leucaena leucocephala (Lam.) de wit (60472 ppm) in the summer season. The highest potassium mineral content was observed for Polyalthia longifolia (27738 ppm)...

The air quality and global environment is immensely affected due to the industrial as well as urban expansion. The present study aims to identify the natural tolerance of six plant species towards the air pollution, which are growing along the Chembur industrial area of Mumbai. The plant’s air pollution tolerance level was identified by evaluating Air Pollution Tolerance Index (APTI) and Anticipated Performance Index (API). The estimation of APTI was done based on the measurement of physico-chemical parameters like pH, ascorbic acid, total chlorophyll content and the relative leaf water content of the fresh leaves of plant species grown along the industrial and non-industrial areas. The higher API values obtained for the Thespesia populnea (L.) Sol. excorrea, Polyalthia longifolia and Albizia saman (Jacq.) Merr plant species growing in the industrial zone indicate a good tolerance towards polluted air and hence are suggested for green zone development in the Chembur industrial area....

Mitigation of air pollution is the major global challenge in the current world. Quality of air is undergoing continuous
deterioration due to industrial and urban development. The present study aims at the seasonal investigation of air pollution tolerance index (APTI) and anticipated performance index (API) of six commonly found plant species namely Ziziphus
jujube (S1), Pithecellobium dulce (Sw.) DC (S2), Celosia argentea L. (S3), Ricinus communis L. (S4), Apluda mutica L. (S5) and
Terminalia catappa L. (S6) growing along the industrial area (Chembur) of Mumbai. The air pollution tolerance indices
were evaluated by using pH, ascorbic acid, total chlorophyll content, the relative water content in the fresh leaves of
plant species growing along the industrial and non-industrial area of Mumbai. The API was determined on combining the
APTI values of the plant species with their biological and socio-economic parameters. The APTI of all the industrial zone
plant species was found to be higher than the non-industrial zone plant species in all the three seasons. The rise in the
mean of the three season’s APTI of S1, S2, S3, S4, S5 and S6 plant species from the polluted industrial zone over the lesspolluted non-industrial zone was found to be 60.14, 76.59, 71.98, 82.30, 71.12, 65.52%, respectively. The higher API values
obtained for the Pithecellobium dulce (Sw.) DC, Ricinus communis L. and Terminalia catappa L. plant species from polluted
zone indicated higher air pollution tolerance and hence are recommended for green belt expansion in the Chembur
industrial area. Terminalia catappa L. is an evergreen plant which can be planted in large number to develop green zone
throughout the year around the Chembur industrial area. Similar studies can be performed globally to increase green
zones around any industrial or residential area which will provide healthy living for the next generations on the earth
