This study reports the seasonal variations in dry deposition of coarse and fine particles on the foliar surfaces of common indoor plants viz. and along with their biochemical changes in the urban households of metropolitan Delhi. The dustfall fluxes were significantly higher at the industrial site as compared to residential site and temporal variations indicated higher dustfall fluxes during the winter months as compared to other seasons. Seasonal concentrations of chlorophylls, pH, and soluble sugars were higher during monsoon season for the indoor plants whereas ascorbic acid content was higher in the winter season indicating more stress. The results of correlation plots revealed that the variations observed in the biochemical traits were interlinked with the changes in dustfall fluxes during different seasons, thereby reflecting the changes in air pollution stress faced by plant foliage. The air pollution tolerance index and anticipated performance index were evaluated to understand the overall tolerance of indoor plants toward air pollution which can be utilized in phytoremediation techniques. It was concluded that among the studied indoor plants, and are better plant species than for improving indoor air quality.
本研究报告了在德里大都市的城市家庭中，常见室内植物的叶片表面上粗颗粒和细颗粒的干沉降季节性变化及其生化变化。与住宅区域相比，工业区的降尘通量明显更高，且时间变化表明冬季的降尘通量高于其他季节。对于室内植物，叶绿素、pH 值和可溶性糖的季节性浓度在季风季节更高，而在冬季，抗坏血酸含量更高，表明压力更大。相关图的结果表明，不同季节降尘通量变化与生化特性的变化相互关联，从而反映了植物叶片所面临的空气污染胁迫的变化。评估了空气污染耐受指数和预期性能指数，以了解室内植物对空气污染的整体耐受能力，这可用于植物修复技术。研究得出结论，在所研究的室内植物中，与 和 相比， 是改善室内空气质量的更好植物物种。
