“…Dust deposition also result in stomata clogging, 25 which results in decreased rate of carbon dioxide exchange, 11 carbon assimilation, 12 transpiration, 13 and therefore net photosynthesis. 15 Rajchidambaram et al (1980) observed clogging of stomata, loss of one or both guard cells or total destruction of stomata apparatus caused by cement dust pollution in all the five species of flowering plants studied by them.…”

In context to the present scenario of urban pollution, there is a growing need for changing the approach of planting trees and other plant species. Addition of the ornamental plants having pollution mitigating ability in the landscape-map may provide the twin-rationale of making the cities green and pollution-controlled. A proper planting-plan may generate healthy and colorful living. The importance of trees in metropolitan environment is now heavily accepted that they too purify the air pollution from the dust-particulates. The rich-biodiversity of India tenders a broad assortment of options to try and reconsider our dust-laden cities and towns. This article describes the way the dust particles affect the plants and trees, and the response of the plants to the particulate-exposure.

“…When it is particularly dry in the Whyalla region red dust plumes raised by sheep coming to water are commonly seen in the distance; this localized dustfall can be measured using simple apparati, as the present authors have shown. When settled on vegetation, this dust is likely to have biological effects; industrial dust has been found to increase transpiration by physically preventing stomate closure (Williams & Ricks 1973), and to decrease photosynthesis and transpiration by shading the leaf surface (Darley 1966;Sheikh et al 1976).…”

Piospheres, that is, zones of attenuating stocking impact extending out from watering places, are a feature of arid pastoral regions. The present authors studied, for the first time, the initial developtnent of a piosphere in respect of a number of variables of the soil surface. The site was near-pristitie chenopod shrubland, part of a paddock of 1340 ha near Whyalla, South Australia, stocked with ca. 200 sheep on a new watering point. Soil features monitored over the first 2.5 years were dung deposition, sheep track developtnent and surface erosion, the soil lichen crust, cotnpaction of the soil surface and dustfall, usitig fenced plots of at least 550 m-as controls,Piosphere patterns (i.e. patterns reflecting the concetitricity of stocking pressure around water) were tnanifest within the first 3 months for sheep dung deposition, sheep track development, and lichen cover. Soil compaction, which was confined to sheep tracks and then largely to the surface 5 ctn, displayed a piosphere pattern when it was first recorded 6 months after stocking. Bulk density of this layer was elevated by up to 20%. There was only a weak piosphere pattern in dustfall. The piosphere patterns tn sheep track development and destruction of the lichen crust became more pronounced in time.

“…The chemical composition of dust, its particulate size, age of plants and deposition rate were studied intensively [19,21]. For example, cement kiln dust reduced 73% of the photosynthesis in green beans [22], while ash reduced up to 90% of the rate of photosynthesis of apple trees [23]. Nanos and Ilias [24] described the effects of cement dust, such as a reduced stomatal conductance and transpiration rate of olive trees.…”

Abstract:The Xinjiang Region in Northwest China is known as the "dust center" of the Eurasian mainland. Dust on the leaf surface affects overall plant development. While emphasis was on studying the impacts of industrial dust particles on crop development, the effect of natural dust deposition on the physiological parameters of cotton had not been studied before. The objective of this study was to examine the effects of dust deposits on cotton leaves and to estimate their impact on crop development and yield. For this purpose, an experiment was set up having two treatments and a control. In Treatment 1, cotton leaves were cleaned with water at three-day intervals or after a natural dust fall. In Treatment 2, 100 g·m −2 of dust was applied at 10-day intervals. The control received neither additional dust nor cleaning. In all of the treatments, stomatal conductance, leaf temperature, biomass and yield were measured. The results show a 28% reduction in yield and 30% reduction in OPEN ACCESSWater 2015, 7 117 stomatal conductance of the dust treatment compared to the control treatment. This indicates blocking of the stomata on the top of the leaf surface. In addition, the canopy temperature of the dust-applied leaves was always higher than the control and treatment.
