DUST-RETAINING PROPERTIES OF WOODY PLANTS ON THE ROCK DUMPS OF DONBASS

A comparative assessment of the dust load of some landscaped and self-overgrown dumps of the Donetsk-Makeyevka urban agglomeration and the territory of their SPZ was carried out on the accumulation of dust from leaf plates Acer negundo L., Acer platanoides L., Robinia pseudoacacia L. as native species characterized by high dust-filtering ability and spread on dumps represented by different composition of composing rocks and Juglans regia L. as a self-bearing species, the dust-retaining properties of which have not been studied. During the research, it was found that Robinia pseudoacacia L. has the highest dust-retaining properties of all the studied plants, and the lowest - Juglans regia L. The leaves of woody plants of the rock dump sh. No. 9 Kapitalnaya are the dustiest due to large areas of stony burnt-out rock. It is assumed that the oxidation process is still active at this dump. For Robinia pseudoacacia L., Acer platanoides L. and Acer negundo L., the dust load indicators on the dumps exceed those in the SPZ by an average of 1.15 times, and for Juglans regia L. – 3 times. Although often Juglans regia L. it is not used for the reclamation of rock dumps, it is most likely a self-bearing species. The measures taken for technical and biological reclamation contribute to reducing the dust load of the territory.
