Assessment of Air Pollution Tolerance Index and Anticipated Performance Index of Plants Growing Alongside the Roads in Sub-Temperate Condition of Himachal Pradesh

Abstract

As the foliage being continually exposed to the atmosphere, absorb, collect and integrate pollutants impinging on their foliar surface, continually they show visible or stubble changes depending on their sensitivity level. Trees remove air pollutants by three means: assimilation by the leaves, deposition of particulates and aerosols over leaf surface, and

Effect of Air Pollutants on Urban Roadside Trees in Shivajinagar & Pashan Area, Pune City

“…[28] Moreover, the sensitivity of a plant species varies from area to area as tolerance of plants towards air pollutants is specific to a site and depends on the type and level of pollution and other atmospheric conditions. [29] There is a reduction in pH, R.W.C., Ascorbic acid content, and Total chlorophyll content (Tables 9a & b) was observed more in Shivajinagar (polluted) area than in Pashan (comparatively cleaner area).…”
