“…GIS-based geostatistics were proved to be a powerful tool in studying soil contamination (Facchinelli et al, 2001). Jin et al (2019) showed through their study that a systematic combination of GIS with multivariate statistical analysis proved valuable for elucidating anthropogenic and natural sources of heavy metals in soil and dust at children's playgrounds in Beijing (China). In the same context, Zawadzki et al (2016) demonstrated that it is possible to use a magneto-geochemical data set in order to discriminate the origins of soil contamination between natural and anthropogenic sources.…”

“…Cr, As, Ni, and Co also formed highly correlated pair with a correlation coefficient of 0.74 and 0.70, respectively, suggesting that these may be originated from some common sources. Industrial wastes, fertilizers/pesticides, and disposal of sewage sludge might be some of the causes for the elevated concentration of these correlated elements [29][30][31]. Both Fe and Ni exhibited strong positive correlations with As.…”

Assessment of potentially toxic elements’ contamination in surface soils of Kulsi River Basin in North East India

et al. 2019

The assessment of potentially toxic elements' contamination in surface soils of Kulsi River Basin in North East India has been studied based on the analysis of 50 soil samples collected from the basin. The average concentrations of Co (2.30 mg/kg), Ni (7.26 mg/kg), Pb (9.41 mg/kg), and Zn (22.7 mg/kg) surpassed the background levels prescribed for sedimentary rocks which indicated anthropogenic contribution of these metals. The average values of enrichment factors for different elements under study followed the order as Co > Ni > Zn > Pb > As > Fe > Cr. Results of multi-element indices revealed significant contamination at many sites; however, computed values for potential ecological risk index indicated only low ecological risk at all the sampling sites. The contribution of individual toxic elements toward the potential ecological risk followed the order as Co > Ni > As > Pb > Zn > Cr. The study recommends that suitable measures need to be taken for checking any further contamination in the area.

“…Nowadays, soil contamination attributed mainly to intense industrialization, urbanization and transport is becoming a global issue [ 1 , 2 , 3 , 4 ]. Soil pollution by potentially toxic elements represents one of the problems for the sustainable development of urban areas.…”

“…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 ]. The abundance of several urban soils meets the requirements for arable soils, and they can be used for cultivation.…”

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.
