Abstract

Modern era has witnessed particulate matter (PM) become one of the biggest threats for the existence of biological species. Therefore, a study was performed in Faisalabad city to evaluate PM retention and removal efficiency of ten local tree species. Branch samples were collected from urban, sub-urban and rural areas in September 2020 (183 days after rain), and in August 2021 (30 days after rain). Results showed that total PM load, PM_>10 and PM₁₀-_2.5 retention was the highest in urban followed by sub-urban and rural area. PM_>10, PM₁₀-_2.5, total PM, and PM deposition rate decreased significantly in the following order, F. benghalensis > T. arjuna > S. cumini > A. scholaris > F. religiosa > E. camaldulensis > D sissoo > C lancifolius > B. ceiba > M. alba during both years 2020, and 2021. During the artificial rainfall experiment, total PM removed by the species also followed the same order however, PM removal efficiency was the highest in B. ceiba and M. alba followed by E. camaldulensis, C. lancifolius, D. sissoo, T. arjuna, S. cumini, A. scholaris, F. religiosa and F. benghalensis. Therefore, it can be concluded that species selection must be done skillfully for congested urban environment.

半干旱环境中十种树种的颗粒物滞留和清除效率

当今时代，颗粒物质（PM）已成为生物物种生存的最大威胁之一。因此，在费萨拉巴德市开展了一项研究，以评估当地十种树种对可吸入颗粒物的滞留和清除效率。分别于 2020 年 9 月（雨后 183 天）和 2021 年 8 月（雨后 30 天）从城市、郊区和农村地区采集了树枝样本。结果表明，城市地区的可吸入颗粒物总负荷、PM>10 和 PM10-2.5 滞留量最高，其次是城郊和农村地区。在 2020 年和 2021 年，PM>10、PM10-2.5、PM 总量和 PM 沉积率按以下顺序明显下降：F. benghalensis > T. arjuna > S. cumini > A. scholaris > F. religiosa > E. camaldulensis > D sissoo > C lancifolius > B. ceiba > M. alba。在人工降雨实验中，各物种去除的可吸入颗粒物总量也遵循相同的顺序，但 B. ceiba 和 M. alba 的可吸入颗粒物去除效率最高，其次是 E. camaldulensis、C. lancifolius、D. sissoo、T. arjuna、S. cumini、A. scholaris、F. religiosa 和 F. benghalensis。因此，可以得出结论：在拥挤的城市环境中，必须巧妙地选择物种。

期刊介绍： The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
