- Abstract
The tolerance against air pollution in plants depends on the nature of air particles and gases. This study was carried out to determine chemical composition of indoor dust and to assess its impact on the biochemical properties of foliage of Ficus elastica in two households with different characteristics of Delhi (India). The dustfall fluxe data of major cations and anions were analyzed to understand the spatial variations in the chemical composition and sources of the deposited particles onto the foliage. The fluxes of anionic species (SO42− + NO3−) were higher at MH (industrial) site as compared to the DH (residential) site. The physiological response of F. elastica was investigated by studying the biochemical constituents, i.e., ascorbic acid, soluble sugars, carotenoids, and chlorophyll a and b, in foliage and variations with respect to dustfall fluxes of anionic species (SO42− + NO3−) in the households. Higher (SO42− + NO3−) fluxes had noticeable impacts on biochemical constituents of F. elastica indicating indoor air pollution stress. Chemistry of dust particles showed influences from indoor and outdoor anthropogenic activities. The morphological effects of dustfall deposition on the foliage were also studied using SEM–EDX. Indoor plants can serve as a platform to capture dust particles and plant responses are influenced by the chemical composition of deposited dust.
