Evaluation of nature-based solutions for biomonitoring of air quality and identification of air pollution-tolerant species
摘要
The study investigates air pollution in Panipat City, attributing it to rapid industrialization, unregulated urban development, vehicular emissions, and population growth. To address this issue, the research explores nature-based solutions, particularly green infrastructure, such as green belts, vegetation barriers, urban green spaces etc. Air quality measurements of SOx, NOx, PM 2.5, and PM10 were taken at three sites (Industrial, Vehicular, and Residential) during pre- and post-monsoon seasons. Concentrations generally decreased in the post-monsoon season, with Industrial sites exhibiting the highest SOx, PM 2.5, and PM10 levels, while Vehicular sites showed the highest NOx concentrations. The study identified 30 plant species across the three sites, assessing their Air Pollution Tolerance Index and Anticipated Performance Index. Ficus religiosa, Ricinus communis, Psidium guajava, and Mangifera indica were identified as excellent pollution-tolerant tree species, while Calotropis gigantea and Cymbopogon nardus were recommended among shrubs. Syngonium podophyllum and Moringa oleifera were suitable ornamental plants for green infrastructure. Conversely, Acacia nilotica, Nerium oleander, Achyranthes aspera, Urena lobata, Rosa rubiginosa, Catharanthus roseus, and Hibiscus rosa sinensis were deemed bio-monitors due to their high sensitivity. Overall, the findings emphasize the potential of plantations in mitigating air pollution and climate change in urbanized and polluted areas.
