Monitoring the dispersed composition of dust particles on the leaf blades of common lilac (Syringa vulgaris), small-leaved elm (Ulmus parvifolia), common apricot (Prunus armenica) in urban agglomeration

Abstract

The article presents the study results of dusty particles on the leaves of tree species forms in the residential area of the Sredneahtubinsky district of the Volgograd region. The aim of the study was to monitor the dispersed composition of dust particles on various types of urban vegetation. Leaves of common lilac (Syringa vulgaris), small-leaved elm (Ulmus parvifolia), common apricot (Prunus armenica) as mass plant species growing in the residential area of the Sredneahtubinsky district of the Volgograd region were chosen as objects of study. The novelty of the work is the study dispersed composition of dust particles on the leaves of common lilac (Syringa vulgaris), small-leaved elm (Ulmus parvifolia), common apricot (Prunus armenica) from the standpoint of random functions expressed by integral distribution curves of particle mass over their equivalent diameters. The measurement of dust particles, dust processing, and the study of dust dispersed composition of was carried out in accordance with GOST R 56929-2016 using the SPOTEXPLORER computer program. As a result of the studies, it was found that the surface of the laminate leaf of common lilac (Syringa vulgaris) and elm have the best adsorption ability small-leaved (Ulmus parvifolia). The study's results are of practical importance - they provide information on the urban plants ability of leaves surface to retain fine-dispersed dust, offer a specific range of plant species for urban green areas, which can use the regional public services greening of urban areas in order to reduce PM2.5 emissions of PM10 in urban areas.
