“…Weak relationship was detected for Cd (0.31). As pointed out by [ 7 , 13 , 14 , 15 ], total metal contents are not sufficient to assess their potential toxicity. Therefore, further considerations are based on mobile fractions only.…”

“…The behavior of potentially toxic elements in the environment, their bioavailability, and toxicity are more related to the forms in which they occur in the soil than to their total content. However, the total metal content is usually taken as the criterion for soil contamination assessment, regardless of their actual availability [ 7 , 13 , 14 ]. In making decisions aimed at reducing soil pollution and the improvement of soil functions, it is critical to analyze the content of mobile metal fractions in soil [ 15 ].…”

“…The analysis of metal content in urban soils is the subject of numerous publications [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Particular attention is paid to green areas due to their use for recreation and the possibility of people’s exposure to contact with contaminated soil [ 2 , 9 , 21 , 22 , 23 ].…”

Comprehensive Evaluation of Metal Pollution in Urban Soils of a Post-Industrial City—A Case of Łódź, Poland

et al. 2020

The pollution of urban soils by metals is a global problem. Prolonged exposure of habitants who are in contact with metals retained in soil poses a health risk. This particularly applies to industrialized cities with developed transport networks. The aim of the study was to determine the content and spatial distribution of mobile metal fractions in soils of the city of Łódź and to identify their load and sources. Multivariate statistical analysis (principal component analysis (PCA), cluster analysis (CA)), combined with GIS, were used to make a comprehensive evaluation of the soil contamination. Hot-spots and differences between urban and suburban areas were also investigated. Metals were determined by atomic absorption spectrometry (AAS) after soil extraction with 1 mol L−1 HCl. In most sites, the metal content changes in the following order: Zn > Pb > Cu > Ni > Cd. About one-third of the samples are considerably (or very highly) contaminated, (contamination factor, CF > 3) with Cu, Pb, or Zn. In almost 40% of the samples, contaminated soils were found (pollution load index, PLI > 1). All metals have a strong influence on the first principal component (PC1), whereas second principal component (PC2) is related to pH. Polluted soils are located in the downtown, in the south and east part of the city. The distribution of contamination coincides with the urban layout, low emission sources and former industrial areas of Łódź.

“…Yet, in most cases the filter media is frequently not a result of deliberate choice but simply given by local soil conditions. It has been shown that soils usually perform well at retaining contamination [17,[23][24][25], but also inevitably become severely polluted themselves, without possibility of regeneration, ending up as hazardous waste [23,26]. The targeted application of filtering as a runoff contaminant removal technique is rare and its benefits are rather overlooked.…”

Treatment of road runoff is a requisite for any environmentally sound infrastructure design. However, investment and maintenance budget is often a limiting factor during the planning and the operation phase of such projects. In order to cost-efficiently decrease the loads of a wide range of contaminants that are usually present in road runoff (posing a long-term threat to the aquatic and soil environments), simple and robust techniques are sought for. The paper deals with the re-evaluation of two such processes, sedimentation and filtration, putting emphasis on using authentic runoff samples during the tests in order to properly characterize the performance of these easy-to-manage solutions in this specific field of application. The results presented in this paper are aimed to aid the proper design of low-cost, low-maintenance road runoff treatment facilities, serving with background information that can be used to ensure that the expectations for the degree of pollutant removal are surely met.

“…PTEs discharged to atmosphere together with dusts and aerosols, are common substances that contaminate environment [e.g. [13][14][15]. Magnetic and geochemical analysis (including Energy Dispersive X-Ray Fluorescence -EDXRF) in topsoil, indicate on presence of TMPs.…”

Technogenic magnetic particles of topsoil from different sources of emission - A case study from upper silesian conurbation, Poland

et al. 2018

Studies on the effects of dust deposition on soils in urban-industrial areas were conducted with application of magnetic (soil magnetometry, thermomagnetic analysis) and geochemical (elements content) methods. The study area covers three different forest sites on Upper Silesian Conurbation. The purpose of the research was an estimation of soil pollution and characteristic of air derived particles. Results show magnetite and maghemite as dominant magnetic components of analyzed soil samples. The highest volume magnetic susceptibility (κ) and no correlation with potentially toxic elements (PTEs) were stated close to metallurgical plant whilst the highest correlation coefficient between κ and PTEs was stated in samples from the urban area and in a vicinity of coking plant.
