Migratory Processes of Heavy Metals and Petroleum Products in the Soil Cover – Surface Water System within the Urbanized Territory

In the large urban urbanized areas, which primarily include the land of Moscow, is developing specific soil and subsoil - urbanozem, the degree of man-made pollution of them by heavy metals, benz-(a)-pyrene and petroleum products is determined by many factors. The author 's estimation of the annual variability of the concentrations of mobile forms of heavy metals, benz-(a)-pyrene and petroleum products in soils of Moscow, based on analysis in 2015 and 2016 is presented. 90 samples at 30 monitoring sites. The object of the author's observation was the soil cover of the city as a whole and some of its natural and technogenic transformed species, as well as the soil cover, which is moved in the process of urban development.

The City

This paper deals with the problem of anthropogenic soil pollution of cities with oil production on the example of Novokuybyshevsk, Samara Region. To assess the modern ecological-geochemical state of soil cover in Novokuybyshevsk in August 2016 the field study was carried out and soil samples for laboratory analysis were selected. The study was carried out on 8 test areas, 7 of which were in different functional zones of the city, significantly differing in environmental conditions. The sample site was in a green area 10 km from the city. Soil samples were collected according to the methods generally accepted in soil science and Geochemistry. The quantitative content of oil products and heavy metals (Ni, Zn, Cu, Pb, Cd, Mn) in soil samples was determined in a specialized laboratory by certified procedures on the equipment, timely verified and calibrated. The data analysis revealed significant anthropogenic transformation of the soil cover in Novokuybyshevsk, which was enriched with petroleum and heavy metals. It also shaped the conditions that increased the migration of heavy metals in soils and their availability to biota. The soils of the city are characterized by relatively even distribution and high content of Zn and Cu. On the contrary, the Mn content is characterized by a rather low rate, which is especially evident for the soil sample area. The accumulation of Zn, Pb and petroleum products in the soils of the city is connected with the influence of the industrial zone. The motor component involves the contamination of soil by Ni, Zn, Si, Cd and petroleum products. No functional area in Novokuybyshevsk contains high levels of Pb concentrations, the content of which exceeded the MPC only in the industrial area. This fact can be associated with the ban of tetraethyl use in gasoline production in Russia in 2002. The obtained results can be used for environmental monitoring of the urban environment and predict changes of ecological-geochemical situation in Novokuybyshevsk in the future.

Metal Building

In the Netherlands the leaching of heavy metals from metal building and constructing materials results in serious contamination problems in the water system. The most common sources of these heavy metals in construction materials are copper waterworks and roofs, zinc roofs, gutters and rain pipes, zinced steel, stainless steel, and lead sealing material. In urban waters the surface water and sediment standards are often exceeded. Although building and construction materials are certainly not the only source of heavy metals, they are an important part of the problem. This article focuses on six instruments that are in use in the Netherlands to try to reduce impact on the surface waters. In addition to this, national as well as international, a reconsideration of the risks and surface water standards for several heavy metals is considered. A balanced use of instruments can be considered as the application of a best practice.

Water And Sediment Quality

The surface water system of Amsterdam is very complicated. Of two characteristic types of water systems the influences on water and sediment quality are investigated. The importance of the sewer output to the total loads is different for both water systems. In a polder the load from the sewers is much more important than in the canal basin. Measures to reduce the emission from the sewers are much more effective in a polder. The effect of these measures on sediment quality is more than the effect on water quality. Some differences between a combined sewer system and a separate sewer system can be found in sediment quality.
