“…Environmental problems are raised due to the adverse effects of vehicle emissions on human health in urban areas [6][7][8][9][10][11][12], especially for pedestrians and residents living in buildings located near roads. Every year the number of controlled vehicles increases, which leads to serious traffic jams [13][14][15][16], as a result of which a large number of various pollutants are released into the air.…”

A significant role in ensuring comfortable living conditions in the urban environment is played by the competent organization of the transport and road complex, which is aimed at ensuring road safety, reducing the load on highways for car density and improving the efficiency of traffic in the city when performing planning and technological measures. At the same time, the current state of the city’s traffic flows as sources of increased chemical pollution of the air environment requires an increase in the distance from streets and roads to residential buildings. This distance should be normalized by chemical and physical indicators of the state of atmospheric air and should be taken into account when red lines are established. In this article we analyze: functional state of the city, road network, composition and intensity of traffic flows for Tyumen. The traffic flows of the city are concentrated mainly in the central part of it. A particularly critical situation is formed at the intersections of cargo-loaded main streets at the hours of maximum traffic intensity and on the main highways of the city. We substitute the provision of regulatory requirements for the chemical pollution level at a distance from the border of the carriageway to the border of residential buildings in order to achieve sustainable urban development.

“…Among the possible sources of anthropic Zn pollution, the main Zn release in the environment arises from tires and other rubber products. Some authors stressed out the close relation between the high amount of zinc in street dust and intense traffic areas . If not used or not recycled, or even reused in other technologies, waste tire wear leachates still contribute to pollution with harmful impacts in the environment and toxic effects onto human cells .…”

The aim of this work is to evaluate the impact of the reduction of zinc content in Ethylene, Propylene and Diene Monomer (EPDM) elastomeric compositions. Vulcanization nanoactivators ZnO 30 (ZnO dispersed in CaCO3) and ZnO 40 (active ZnO) were used as reinforces in the elastomers, and both the properties and the cytotoxicity were investigated and compared to those of EPDM with a standard zinc oxide (sZnO) commonly used in the bus rubber profile industry. After a complete description of the physico‐chemical characteristics of whole zinc oxides, the vulcanization activators were dispersed in EPDM. Although elastomers with sZnO display a cytotoxic behavior, EPDM formulations containing ZnO 30 and ZnO 40 appeared to be environmental friendly while displaying similar mechanical properties to that with sZnO composition. ZnO 30 represents the most interesting vulcanization activator to replace sZnO allowing a reduction of 77% in the zinc content without any loss of mechanical properties. Moreover, the formulations associating this nanoactivator show the lowest release of Zn2+ in water with a poor cytotoxicity in comparison to sZnO. POLYM. ENG.

“…The number of vehicles being driven has increased every year, and has led to severe traffic congestion [1][2], causing high amounts of multiple pollutants to be emitted into the outdoor air. Environmental concerns have been raised on the adverse health effects of vehicle emissions in micro-scale traffic-crowded street canyons [3][4][5][6][7][8][9], especially for pedestrians and residents living in near-road buildings. Regularly reported data about air emissions in the Russian Federation made the basis for listing environmentally hazardous cities.…”

Abstract. The article deals with the problem of street lines which determine specific conditions of usage and development of towns and cities. The city transport system is one of the complex and overwhelmingly important elements of the big city structure. The investigation of its constituents, development arrangement and planning system is one of the actual directions of theoretical research having significant practical meaning for efficient use of territories. Nowadays federal legislation pays great attention to providing complex and constant development of territories. One of the major instruments in achieving this goal is the usage of street lines. Planned objects marked by street lines have legal characteristics. This article reveals those characteristics.
