Emissions of Petroleum Products from Roads into Roadside Soils as Part of Exhaust Gas Emissions and Surface Wastewater

Abstract

The highway causes an intensive emission of petroleum products into the roadside space and their active deposition by soils to ecologically dangerous concentrations. We considered two main ways of petroleum product transfer from the road: air (dispersion in the atmospheric air of gaseous emissions of vehicles) and water (with surface wastewater formed on roads, as a result of flooding of roadside territories and splashdown). Based on the data of the physical and chemical analysis of air, water and soil environments, a tentative assessment of the intensity of petroleum products transfer from the highway to the roadside soils by each of these ways was made using the ratio of concentrations of aliphatic and aromatic hydrocarbons in the exhaust gases, surface waste water formed on roads and in soils of the nearest roadside space as an indicator. According to the results of determining this indicator, it was found that in the emission of petroleum products from the highway and their accumulation in the soils of the roadside space, the entry of these contaminants in the exhaust gases by air predominates.
