“…Množství vyluhovaného Cs horkou lučavkou v půdní jemnozemi (bez částic větších než 2 mm) bylo v průměru 1,1 mg kg -1 , což odpovídá zhruba 20 % celkového obsahu Cs. Ve výluzích získaných stejným způsobem byly mapovány desítky prvků včetně Cs v půdách v centru Prahy 19 . Výsledky, včetně poměrně nízkého poměru Rb/Cs reprezentujícího zřejmě jílové minerály (průměr vyluhovatelných Rb a Cs 14,8, resp.…”

Cesium is the heaviest stable alkali metal (with only one stable isotope – 133Cs) and it occurs mainly as a potassium-substituting cation. It is an important trace element in rocks typical for the Earth crust, and its content in biomass is also relatively high compared to those abiogenic elements which are little soluble. Low-cost analytical methods like X-Ray Fluorescence are inadequate to quantify cesium in typical natural samples, so that the usage of ICP-MS (Inductively-Coupled-Plasma Mass Spectrometry) or INAA (Instrumental Neutron Activation Analysis) is necessary. Nevertheless, investigation of the pollution with the radioactive isotope 137Cs, which is an important fission product and can be measured with gamma-ray spectrometry, also contributed to the knowledge of biogeochemistry of cesium. It has been shown that Cs is usually strongly retained in humus (thank to clay minerals), or is cycling intensely within the soil-biomass system, being only slowly removed (at least, this is valid for ecosystems in temperate climate). The results of extensive biomonitoring in Czech coniferous forests (with prevailing spruce) also show that Cs is concentrated in humus (relatively to all other alkali elements) by natural processes.

“…As shown in Table S3, metal levels in urban soils, suburban soils, and peri-urban soils were different, which might be ascribed to the effect of urbanization and land uses (agricultural, industrial, mining, residential, recreational, and commercial areas). It is commonly believed that anthropogenic sources for these metals covered industrial activities (mining, coal combustion, smelting, iron and steel production, and metal processing), traffic sources (combustion of fossil fuels, wear and tear of vehicle components, and loss by friction), agricultural activities (herbicides/pesticides, wood preservations, and fertilizers), oil-and coal-related activities (combustion of fuel-oil), construction sources, and urban wastes (Xia et al, 2011;Poňavič, Wittlingerová, Čoupek, & Buda, 2018;Wang, Zeng, et al 2018;Zhang, Lu, Shi, & Pan, 2018;Timofeeva, Kosheleva, Semal, & Burdukovskii, 2018). In this study, most of the metal concentrations were higher inside of the campus than those from outside, likely due to anthropogenic effects such as urbanization.…”

Metal status in soils within a developing education park: Potential risk of land development

Many countries have developed university/college towns with specific characteristics (temporal, spatial, structural, and functional aspects). During the land development, there were obvious changes in soil metal levels and distribution patterns attributed to anthropogenic activities, thus having induced comparable results in university/college towns due to similar anthropogenic activities. Until now, specific studies on the metal status in university/college towns, especially the variation inside and outside of a campus were rarely involved. Herin we report on 109 soil samples around a new campus within a developing education park, in which the levels, spatial distributions, and possible sources of (alkali, alkaline-earth, transition, and main group) metals and metalloids (Cd, Cr, As, Pb, Zn, Cu, Mn, Ba, Ni, Ti, Be, Bi, Sb, Sn, Co, V, and Zr) were systematically investigated. The Nemerow pollution indexes, spatial analysis, principal components analysis, and cluster analysis were calculated and analyzed. The results showed that the level of most metals within the campus with different functional areas (college, activity, and greening areas) was 1-1.3-times as much as that outside in four directions and had greater variations. Moreover, the level of most metals was 1-1.5-times as much as their background value and they distributed in the areas under specific developments and might mainly be attributed to anthropogenic sources. These findings provide the knowledge about effects of land development and anthropogenic activities on soil metal status that could be used by university/college towns in the similar context around the world.

“…Anthropogenically, the soil has been contaminated by fast industrial expansion and subsequent effluent discharge or exhaust emissions, agricultural fertilizers and pesticides, mining operations, population explosions, and subsequent urban dwelling pollution [6,[38][39][40][41][42][43][44][45]. Anthropogenic activities are generally regarded as being the primary source of PTEs in the soil in highly developed, urbanized and industrial urban areas [46][47][48][49], mining areas [5,[50][51][52], or agricultural sectors [41,53]. However, a large body of research on this subject supports the importance of the geological background in contributing to higher PTE contents in soil [2,[33][34][35][36][37]54,55].…”

Contamination Levels and the Ecological and Human Health Risks of Potentially Toxic Elements (PTEs) in Soil of Baoshan Area, Southwest China

et al. 2022

The primary goals of this study were to reveal the environmental status of potentially toxic elements (PTEs) and their ecological risks, as well as their associated health risks in the Baoshan area, southwest China, which has been surveyed with the scale of 1:250,000 geochemical mapping. Based on a comparison of the PTE concentrations with the soil environmental quality of China and the enrichment factor (EF), geo-accumulation index (Igeo), contamination factor (Cf), and potential ecological risk indexes ( and PERI), as well as the potential non-carcinogenic hazard indices (HI and CHI) and carcinogenic risks indices (TCR and CTCR), the following conclusions were drawn: The PTE concentrations in the surface soil samples that were collected from the investigated area (1.65% sites) exceeded the risk intervention values (RIV) for soil contamination of agricultural land of China. Cadmium (Cd) and mercury (Hg) posed higher ecological risks than other PTEs (arsenic (As), chromium (Cr), lead (Pb), copper (Cu), nickel (Ni), and zinc (Zn)), which was highlighted by their toxic response factor. Arsenic was the main PTE with a non-carcinogenic risk (19.57% sites for children and 0.25% sites for adults) and the only PTE that carries a carcinogenic risk (2.67% sites for Children and 0.76% sites for adults) to humans in the research area. Children are more vulnerable to health risks when compared to adults because of their behavioral and physiological traits. Geological genesis was responsible for the high concentrations, ecological risk, and health risk distribution patterns of the examined PTEs. Even though the present research highlights several important aspects related to PTE pollution in the research area, further investigations are needed, especially in mining areas.
