Phytoremediation potential of potted plant species against vehicular emissions.

Urbanization and industrialization are exponentially deteriorating air quality, ecosystems, and human health. Phytoremediation is cost cost-effective, sustainable, and nature-based solution against air pollution. This study is designed to evaluate four species, , a, , and for their phytoremediation potential. The experimental setup consisted of a sealed chamber to place potted plants and equipment, it was also connected to the vehicular exhaust pipe. The Air Pollution Tolerance Index was highest for (12.19) and lowest for (8.58) has the highest VOC removal efficiency (90%, 0.172 ppm h). NO remediation was highest by with 0.057 ppm h (77%) removal efficiency. SO and CO were remediated more efficiently by as 89%, (0.18 ppm h) and 80% (0.23 ppm h), respectively. reduced a higher concentration of NH (77%, 0.06 ppm h) compared to other species. and may serve as bio-indicator species. These findings provide a sustainable, natural, economical, and eco-friendly way to mitigate air pollution. and are suitable species for urban landscapes, green spaces, urban plantations, and green walls to curb air pollutants due to traffic and industries.
