IMPACT OF AIR QUALITY ON THE QUALITY OF SURFACE RUNOFF CAPTURED FROM ROADS IN URBAN ENVIRONMENTS.

At present, surface runoff represents serious environmental problems in the urban environment, causing adverse effects on socio-economic and natural systems. Surface runoff is a complex source. The creation of surface runoff is described by various hydraulic hydrological processes, from the impact of water on the surface to the mouth into the sewer network or recipient. The formation of the precipitation-runoff process depends on several factors. Land-use change is a key factor that significantly affects the quality and quantity of surface runoff. In addition, the quality of surface runoff is also influenced by precipitation characteristics and air quality. In the last few years, the air quality is significantly worsened. The reason for this is the rapid development of urban areas, transport, and technical infrastructure. As a result of these phenomena, excessive gases, particularly carbon dioxide, methane, sulfur dioxide, and nitrous oxide, were produced. Due to many research, emission in the atmosphere accounts more than 50 % of atmospheric precipitation pollution. In recent decades, attention has been paid to rainwater quality due to the water crisis. The current use of large amounts of quality water and the removal of heavily polluted water causes significant damage to the aquatic ecosystem. Given the facts, the paper focuses on analyzing the quality of surface runoff captured in urban areas. Subsequently, a comparison of the influence of air quality on the quality of surface runoff is performed. The study results could help design the proper management of surface runoff in urban agglomerations concerning environmental protection and the possibility of rainwater reuse. [ABSTRACT FROM AUTHOR]
