Abstract

The environmental problems of the road transport system in Tashkent are analyzed in the article. Particulate air pollution is one of the most serious problems. To reduce dust pollution in the air, it is proposed to create protective screens along highways from lianas. It was proposed to form screens from fragrant honeysuckle (Lonícera caprifólium) and ivy (Hedera helix), which are evergreen in the conditions of Tashkent. The study of the dust-absorbing capacity of the leaves of these plants showed that ivy leaves are the most dust-absorbing, capable of holding up to 1.64 mg of dust per 1 cm2 of the surface.

Summary

Introduction

During the years of independence, an intensive growth of motorization has been steadily observed in Uzbekistan. Considering the level of motorization in large cities (in Tashkent, for example, there are 168 cars per 1000 inhabitants [1]), the problem of pollution becomes catastrophic and requires urgent action. Road transport is not the least factor in the climate change process, as cars emit significant amounts of greenhouse gases (GHG), (various sources indicate the share of CO2 emissions from road transport from 13 to 27% of global emissions). In 2004, transport contributed approximately 23% of total energy-related GHG emissions, with CO2 and N2O emissions of about 6.3–6.4 GtCO2-eq CO2 emissions from the transport sector (6.2 GtCO2-eq in 2004) have increased by approximately 27% since 1990 and are fast growing in end-use sectors. Road transport accounts for 74% of total transport CO2 emissions [2, 3]
