“…The distribution and speciation of PTE in soil and aquatic systems are controlled by Fe-Mn [27][28]. Al is mainly influenced by geology background, and elevated in clay areas [29]. The soil Corg is not related to all PTEs, except that it has a low significant correlation coefficient of 0.156 with Pb, which is inconsistent with most previous research results [30].…”

Potentially toxic elements (PTE) pollution in soils has become a major global environmental problem, and their spatial distribution and risk assessment are essential issues of concern to human beings. To analyze the distribution characteristics and the pollution levels of arsenic, cadmium (Cd), chromium, copper, mercury, nickel, lead and zinc in soil, 573 surface soil samples were collected from the karst region (karst area, K; denudation monadnock with solutional cap rock, KSC; non-karst area, NK) in Mashan County, Guangxi Province. The pollution load index (PLI), potentially ecological risk index (RI) and Nemerow composite pollution index (NCPI) were employed to assess the pollution levels of PTE. The PLI and RI results revealed that the soils have undergone relatively low-moderate contamination due to the high geological background. The average concentration of PTE in different soils were in the following decreasing order, K>KSC>NK. The concentration of Cd in 75.74% of samples exceeded the risk screening values of GB 15618-2018. The relatively high pollution level of PTE was mainly distributed in K soil, rich in calcium, magnesium and an alkaline environment. Therefore, there is a higher risk of pollution in areas with high background of heavy metals in karst areas. The clean-precaution and light pollution levels in the NCPI risk assessment were distributed in NK and KSC areas, respectively. However, metal ores and human activities caused the deviation of the clean-low risk and lithological distribution in the NK and KSC areas.

“…Higher levels of Pb were found in the urban area [102.805 (84.335-110.625) vs. 62.080 (35.781-68.140); data presented as median and 95% CI, in mg/kg], which did not show statistical differences, perhaps due to the wide dispersion observed, which is characteristic of Pb and is well described in the literature. Leicester soils are less contaminated by Pb than in other, larger British cities, such as London (180.1 mg/kg) [17]. The urban region was subdivided into four ordinal directions to study the distribution of this metal.…”

“…Studies of transformational processes of natural soils in urban areas in general have been conducted by many scientists [16][17][18][19][20][21][22][23][24][25]. Given the fact that urban soils play an important role in accepting air pollution from emissions from vehicles and industrial enterprises, as well as the fact that in the context of the Covid-19 pandemic there were changes in these anthropogenic factors, quantitative changes in agro-ecological indicators of soils of the territories under quarantine are possible.…”

The article considers the changes in some agrochemical parameters and the content of plumbum in the soil cover of a medium-sized urban ecosystem after the introduction of quarantine measures in connection with the Covid-19 pandemic. It has been determined that the blocking of anthropogenic activity did not affect the content of humus. There were changes in soil pH, which led to the transition from an alkaline reaction to a neutral one. The amount of fertilizer elements (NPK) in the soil in the post-quarantine period has been increased. The content of the mobile (active) form of plumbum within the city has been halved on average. In general, the impact of quarantine from Covid-19 on the condition of the soil cover as well as on air and surface water can be preliminary considered as positive.
