Abstract

The major sources of dust pollution include suspension of soil, agriculture-related activities, road dust, vehicular exhaust, power plants, construction activities, open fires, brick kilns, cement factories and volcanoes. Due to this pollution, plants suffer from stomatal closure leading to cell/tissue changes, leaves' necrosis, pigment loses and chlorosis. The first physiological reaction after dust deposition to the vegetation takes place on the leaf with reduced net assimilation efficiency. Moreover, the long-term depositions change the photochemistry leading to retarded leaf growth. Deposits for many years over plants' surface lead to a large-scale reduction in the assimilate balance. Additionally, there are few reports on abrasive effects of dust, especially under high wind speed; supporting secondary effects such as an increase in diseases and pest incidence after the protective leaf cuticle were removed physically. Changes in soil chemistry due to dust deposition in the rhizosphere also lead to a change in soil nutritional values. In this article, we summarized the influences of dust pollution on various parameters of vegetation.

Accelerating the Height Increase of Mersawa (Anisoptera marginata) Seedlings through Inundation Height with and without Water Treatments

“…Amina et al (2020) stated that the absence of several types of stomata in plants of the same species collected from polluted sites could be related to the ability of cement dust to clog, denature, and destroy plant stomata. Likewise, Kameswaran et al (2019) stated that dust particulate deposition can cause stomata blockage on the upper and lower surfaces of the vegetation. Clogging the leaf stomata decreases the transpiration rate of carbon assimilation, reduces photosynthesis, and results in stunted growth.…”

Fine Particulate Matter Reduction through Crop Surface Adsorption in an Agricultural Field Using the Coefficient Derived from Wind Tunnel Experiments

“…Airborne dust includes fine and ultrafine PMs that have become airborne due to soil erosion [11]. Fine dust blocks the stomata of vegetation, causing necrosis of cells and tissues and whitening of leaves, thereby inhibiting the growth of plants [12], and fine dust containing salt content induces salt damage resulting in withering plants [13][14][15][16].…”
