Abstract

Plants in general and those which are susceptible to the environmental pollution in particular, can act as bio-indicators for assessing the air pollution. Moreover, the plants which show tolerance to environmental deteriorations can be helpful as bio-monitors and metigators for air pollution. The present study was conducted to evaluate the tolerance level of dominant plant species in the twin cities of Pakistan i.e., Islamabad (a model city) and Rawalpindi (an old city). Extensive fieldwork was done on roadsides of Rawalpindi and Islamabad (roads demarkating these cities). A total of 201 plants were documented out of which thirteen plant species were found as dominant i.e. Alstonia scholaris L. (Devil tree), Ficus benjamina L. (Weeping fig), Melia azedarach L. (chinaberry tree), Rosa indica. L. (Cyme rose), Terminalia arjuna (Roxb.) Wight & Arn. (Arjuna), Pongamia pinnata L. Pierre. (Pongame oil tree), Jasminum humile L. Revolutum. (Jasmine), Morus alba L. (silkworm mulberry), Robinia pseudoacacia L. (black locust), Ficus carica L. (common fig), Azadirachta indica A. (neem), Dalbergia sissoo Roxb. (shisham). The biochemical, physiological, and socio-economic parameters, Air Pollution Tolerance Index (APTI) and Anticipated Performance Index (API) were evaluated. Our findings further showed that proline and sugar content were found higher in the plants of Rawalpindi than in Islamabad while few other physiological and biochemical parameters showed higher levels in the plants obtained from the Islamabad site as compared to Rawalpindi. The plant species A. scholaris, T. arjuna, B. papyrifera, and R. pseudoacacia serve as bio-monitors and are the most desirable and most effective tolerant species for air pollution and green belt developments of these cities. These plants can be recommended for metigation of air pollution and smog in other cities having the same climate.

通过利用植物的预期性能和空气污染耐受指数，为空气污染的城市环境带来可持续发展的解决方案

一般植物，特别是易受环境污染影响的植物，可以作为评估空气污染的生物指标。此外，对环境恶化表现出耐受性的植物可以作为空气污染的生物监测器和计量器。本研究旨在评估巴基斯坦双子城，即伊斯兰堡（模范城市）和拉瓦尔品第（老城）主要植物物种的耐受程度。在拉瓦尔品第和伊斯兰堡的路边（这两个城市的标志性道路）进行了广泛的实地考察。共记录了 201 种植物，其中 13 种为优势植物，即 Alstonia scholaris L.（魔鬼树）、Ficus benjamina L.（垂枝无花果）、Melia azedarach L.（金樱子树）、Rosa indica.(Cyme rose)、Terminalia arjuna (Roxb.) Wight & Arn. (Arjuna)、Pongamia pinnata L. Pierre.(茉莉）、Morus alba L.（蚕桑）、Robinia pseudoacacia L.（黑刺槐）、Ficus carica L.（普通无花果）、Azadirachta indica A.（印楝）、Dalbergia sissoo Roxb.（芝麻）。对生化、生理和社会经济参数、空气污染耐受指数（APTI）和预期绩效指数（API）进行了评估。我们的研究结果进一步表明，拉瓦尔品第的植物中脯氨酸和糖的含量高于伊斯兰堡的植物，而与拉瓦尔品第相比，伊斯兰堡的植物中其他一些生理和生化参数的含量更高。植物物种 A. scholaris、T. arjuna、B. papyrifera 和 R. pseudoacacia 可作为生物监测器，是这些城市空气污染和绿化带开发中最理想、最有效的耐受物种。这些植物可以推荐给气候相同的其他城市，用于缓解空气污染和烟雾。
