Technogenic Surface Formations

On the territory of the left-bank part of Perm, the urban pedocomplexes (UPC) were distinguished as a combination of soil and technogenic surface formations on the same soil-forming rocks within a certain functional zone. Within the UPC, formed on eluvial-deluvial loams and clays in the zone of multi-storey buildings, the surface horizons of soils and TSF (technogenic surface formations) were studied. A change in the zonal trend of humus formation in reclaimed soils was observed as an increase in the content of organic matter, as well as in a change in the type of humus to the humate side. The conservation of zonal features of humus formation in non-purposefully recultivated urban soils and TSF was noted. It manifests in a low or medium content of organic carbon, the formation of a humate-fulvate type of humus.

Urban soils are at the interface between land and people and provide a wide variety of important ecosystem services to highly populous areas. The aims of this soil survey were (1) to measure the bulk density, carbon (C) storage and pH of surface soils (0–15 cm depth) from public spaces (parks and road verges) in the city of Liverpool, UK, and (2) to determine the likely impact of these master variables on heavy metal concentrations (As, Cd, Cu, Pb and Zn). The bulk densities and organic matter contents varied considerably in the predominantly sandy textured soils within the city boundary, resulting in diverse C densities from 1–10 kg C m2. Organic carbon formed the majority of the labile, water-soluble and extractable C pool in these soils, a fact not easily elucidated from their organic matter or C content alone. The copper and lead concentrations in the sampled soils were correlated with organic matter and organic carbon in water-extracts. Cadmium and zinc appeared to be dependent only on soil pH, whilst arsenic was related positively to organic matter, but negatively to pH. Interrelationships, and hence synonymous distributions, of all metal(loid)s existed, but were strongest between Cu and As, and Cu and Pb. These results suggest that the diverse bulk densities, and hence carbon storage, of the urban soils surveyed influenced the dispersal of metals and arsenic.

The current study included the investigation of several metals and their distribution in urban soils from parks and green areas in the city of Belgrade. The soils were sampled in January and February 2008. The concentrations of Cd, Co, Cu, Pb, Mn and Zn were measured, as well as the pH values and organic matter contents. The obtained results showed that there was a significant level of contamination in some samples, especially with lead, and that it was most probably caused by anthropogenic activities, mostly from traffic. The results were compared with the National legislation and Netherlands standards. Also, the recent results were compared with the data from previous work and it was concluded that there has been a certain increase of the Pb concentration in the past three years. The level of pollution in playground soil was very high and each analyzed sample exceeded the Dutch target value for Cd, Co and Pb.

Ensuring and maintaining the environmental safety of the urban population living in an industrial city in the vicinity of a large city-forming enterprise in conditions of constant emission of industrial dust and gases into the air has always been and is today one of the urgent problems of the architecture of the city of Magnitogorsk. The article examines the historically existing urban planning situation in Magnitogorsk in the conditions of the climate and wind direction of the South Urals, the accounting of which largely contributes to the protective qualities of the air despite the significant emissions of man-made pollution into the atmosphere of the Magnitogorsk Iron and Steel Works (MMK). The original location of industrial buildings and residential areas during the construction of Magnitogorsk was carried out in the 30s of the XX century on the basis of a purely economic approach, bringing housing as close as possible to production, not taking into account wind flows from the construction site and cutting down perennial trees on the slopes of magnetic mountains for the construction of buildings and structures ... After 10 years of MMK operation, the significant role of the South Ural wind in maintaining the ecological situation in the city was proved. Until now, thousands of city residents continue to live in close proximity to MMK, feeling the harmfulness of industrial emissions that pollute the atmosphere. Later, the residential zone of the city began to develop to the south along the right bank, and the industrial zone to the north along the left bank of the river, thus creating further many unfavorable environmental problems that sometimes have to be eliminated.

Data on cadmium distribution in the soils of industrial, residential and recreational areas of Dniprodzerzhinsk city are presented. According to the classification of urban soils the following types of soils were identified in the city: urban soil proper, plantosoil, anthropogenic-surface-transformed natural soil and lawn soil. We have made the estimation of cadmium content. The problem of soils contamination in the city with high anthropogenic load is discussed. The total cadmium content in the industrial, residential and recreational soils of Dniprodzerzhinsk varies within 0.6–10.5 mg/kg, but movable forms make 0.1–3.4 mg/kg of soil. Cadmium in the urban soil proper of the right-bank city surpasses the maximum permissible concentration (MPC) twice. At the same time the soils in the left-bank area and in the eastern and western areas of the right-bank were under MPC.

Abstract The aim of the study is to find the relationship between the land surface temperature and air temperature and to determine the hot spots in the urban area of Bucharest, the capital of Romania. The analysis was based on images from both moderate-resolution imaging spectroradiometer (MODIS), located on both Terra and Aqua platforms, as well as on data recorded by the four automatic weather stations existing in the endowment of The National Air Quality Monitoring Network, from the summer of 2017. Correlation coefficients between land surface temperature and air temperature were higher at night (0.8-0.87) and slightly lower during the day (0.71-0.77). After the validation of satellite data with in-situ temperature measurements, the hot spots in the metropolitan area of Bucharest were identified using Getis-Ord spatial statistics analysis. It has been achieved that the “very hot” areas are grouped in the center of the city and along the main traffic streets and dense residential areas. During the day the "very hot spots” represent 33.2% of the city's surface, and during the night 31.6%. The area where the mentioned spots persist, falls into the "very hot spot" category both day and night, it represents 27.1% of the city’s surface and it is mainly represented by the city center.

The impact of the urban effluents of Mytilene (Lesvos island, Greece) on the receiving coastal marine environment, was evaluated by studying the quality of the city effluents (BOD5, COD, SS, heavy metals) and the marine sediments (grain size, organic matter, heavy metals). It was found that the urban effluents of Mytilene contain high organic matter and suspended particle load because of septage discharge into the sewerage network. Furthermore, although the city does not host important industrial activity, its effluents contain appreciable metal load, which is mainly associated with the particulate phase. The city effluents are discharged into the coastal marine environment and their colloidal and particulate matter after flocculation settles to the bottom, where is incorporated into the sediments. Over the years, the accumulation of organic matter and metals into the harbour mud has created a non-point pollution source in the relatively non-polluted coastal marine environment of the island. Copper and Zn were the metals which presented the higher enrichment in the sediments of the inner harbour of Mytilene.

The article considers the developed model of the closed-cycle economy, which, along with economic parameters, takes into account pollution and consumption of building materials suitable for recycling. The model reflects the idea that the economic growth of a society alone cannot maintain or improve the existing quality of the environment, and for this it is necessary to increase the recycling rate. The purpose of the study is to reveal the factors influencing the increase in the level of recycling when introducing efficient and environmentally friendly systems for managing construction waste in megacities. The results of the study will affect the improvement of the quality and standards of life of the city population, the creation of favorable conditions for a safe, healthy and the prosperous life of people while ensuring the economic growth of the city. The process of the managing the growing volume of construction waste is reflected, recycling is emphasized.

The article analyzes the processes of suburbanization and transformation of the spatial structure of the city of Ulan-Ude. Modern trends in the growth of Western and historical factors of development, due to socio-economic and historical factors of development. In the 1990s-2000s, because of the decline in agriculture and, as a result, the lack of jobs, the rural population began to migrate massively to the Buryat Republic’s capital. However, the prices for houses and apartments in the city center were unbearable for many migrants, so the purchase of land plots and the construction of houses were affordable for many. The estrangement of agricultural lands and their inclusion in residential areas allowed the city of Ulan-Ude and suburban areas to somewhat expand the territory of settlements and create a huge number of GNPP (gardeners non-profit partnership) and DNPP (dacha non-profit partnership). The city and suburban areas were not ready for such a flow and were not able to provide the newly arrived migrants with social, road transport and communal infrastructure. As a result, the city was surrounded by a suburbia almost devoid of any infrastructure. There are some elements of false urbanization or squatter area, which is a type of urbanization in which the urban population rapid growth is not accompanied by a commensurate increase in urban functions. In recent years, the growth rate of suburban settlements has decreased, mainly due to mortgages, which have become more affordable for the population and the growth of multi-storey construction. In addition, the village is slowly depleting the human resources that feed the city and the suburbs. In other words, those who wanted to move to the city have already moved

Background Levels

&lt;p&gt;Soil contamination is widespread across Europe. In particular, contamination of urban soils by metals is poorly characterised. This is a major environmental concern, especially given that urban recreational amenities may be located on former industrial sites and/or may possess ex situ soils derived from industrial areas. We surveyed soils from nine urban recreational sites (15 samples per site) in Cork city in order to assess the degree of metal contamination. The results show that Pb concentrations exceed national background levels in all soil samples from all sites by a mean of 600 % and at least 140 %. Mn, Fe and Zn are enriched above background levels in all soil samples from three (Mn and Fe) to five (Zn) of the sites and, at the remaining sites, show 7 &amp;#8211; 14 localised hotspots. Similar hotspots characterise Cu, Rb and Sr, which each exceed background levels at eight or more sampling locations at four sites. Co, Ni, As and Sn concentrations exceed background levels in at least three hotspots at each of three to six sites. Overall, metal concentrations are highest in the sites closest to the city centre, reflecting diverse sources that potentially include traffic and current and historical domestic coal burning and industry. At each urban site, the element grouping Zn and Pb recurs in 50 to 80 % of locations and enrichment in the element grouping Mn, Fe, Cu, Zn and Pb recurs in approx. 50 % of locations; Ni and As recur in approx. 10 % of the locations. At three sites, elevated concentrations of Mn, Fe, Cu, Zn and Pb are associated with high LOI (Loss-on-ignition) values &amp;#8211; a proxy for the amount of soil organic matter present &amp;#8211; and near-neutral pH values. Conversely, low LOI and acidic pH values are associated with lower concentrations of these elements. This indicates that soil metal concentrations are influenced by the amount of organic matter present and by pH. &amp;#160;Future analyses and experiments will further investigate links between soil organic matter and metal concentrations.&lt;/p&gt;
