“…In most cities, contaminants tend to be poorly retained and quickly exported to other areas or stored in soils, sediments, and organisms within urban and peri‐urban areas. This relative transience and rapid short‐ to long‐term storage are due to the presence of predominantly impervious surfaces that can themselves be contaminant sources (Diamond & Thibodeux, 2011; Webb et al., 2019). In such environments, PM deposition is among the main mechanisms of contaminant movement, which is affected by wind conditions (e.g., predominant direction, speed, duration, magnitude, and timing) and deposition surface properties (type, size, proximity to emissions, and geometrical aspect relative to contaminant sources).…”

“…Redeposition from proximal sources can occur through erosion and entrainment of TE‐bearing PMs from nearby soils, including from nearby cultivated areas (Clark et al., 2008). Other proximal sources may introduce TEs from outside of cities, mainly in the form of industrial emissions and vehicular traffic (Mielke et al., 2010; Vittori Antisari, Carbone, Ferronato, Simoni, & Vianello, 2012), which combine imported materials and fuels to produce contaminants that will eventually be redistributed within a city (Laidlaw & Filippelli, 2008; Webb et al., 2019). Vehicular traffic burden is typically indicative of the intensity of TE contribution that can be expected generally (Adamiec et al., 2016; Al‐Taani, Nazzal, & Howari, 2019), and for CUAs in particular (Säumel et al., 2012).…”

“…However, concerns have been increasingly raised over trace element (TE) contamination undermining urban food production (Brown, Chaney, & Hettiarachchi, 2016; Cheng et al., 2015; Hursthouse & Leitão, 2016; Wortman & Lovell, 2013). Trace element contamination is a widespread problem in cities (Meuser, 2010; Webb, Rubio, & Fullen, 2019), especially in economies based on endless capital accumulation (McClintock, 2015).…”

Atmospheric sources of trace element contamination in cultivated urban areas: A review

Producing food in cities has garnered increasing attention over the past decade. Although there are ecological and social benefits, cultivated urban areas (CUAs) also bear contamination hazards, including from trace elements (TEs). Trace element contamination has been studied extensively in CUAs, but atmospheric sources remain understudied and poorly understood. A brief discussion is offered on atmospheric particulate deposition processes in cities and their implications for urban food production. Available findings are discussed and contrasted. Existing research assesses atmospheric deposition indirectly or otherwise lacks controls for other TE contaminants. There is little to no engagement with methodological guidelines from the atmospheric sciences, which reduces confidence in the findings so far attained. Suggestions are delineated to combine techniques used in the atmospheric sciences with the robust methodologies already generated by studies on TE contamination in CUAs, such as isotope and TE ratios analyses.

“…Soil pollution is related to agricultural safety production, cultivated land quality, and people's health. The National Soil Pollution Status Survey Bulletin, jointly issued by the former Ministry of Environmental Protection and the Ministry of Land and Resources in 2014, showed that the total over-standard rate of soil pollutants in China is as high as 16.1%, indicating that the soil conditions in China are not optimistic [1]. With the awareness of environmental protection and sustainable development, people began to realize the negative effects of soil pollution on production systems and their lives.…”

“…However, the evaluation indicators only focus on the physical and chemical characteristics of the soil and do not pay attention to the relationship between soil pollution and economic and social factors, agricultural development, climate, and meteorological changes. These relatively easy soil environmental assessment methods have a limited effect on the prevention and reduction of soil pollution [16][17][18][19]. Secondly, considering the complexity of soil data environment, existing evaluation methods cannot describe the overall characteristics of the soil environment well and cannot trace the main causes of soil pollution.…”

Soil pollution has become one of the most important environmental issues in China. It is very important to evaluate soil environmental quality comprehensively and objectively. This paper proposes a soil environment quality assessment model based on the Driving Force-Pressure-State-Impact-Response (DPSIR) model and data fusion. At first, 18 evaluation indicators are selected, including complex indexes, such as the industrialization index, heavy metal pollution index, organic pollution index, potential ecological risk index, and human health risk index, and single indexes such as population density, fertilizer/pesticide application intensity, annual average air quality index, etc. Then, hierarchical analysis model is constructed, and the weight of each indicator is calculated based on Analytic Hierarchy Process (AHP) method. According to the quartile of indicator values of 32 provincial administrative divisions on the Chinese mainland, the values of each indicator are standardized and graded. Finally, the soil environmental quality index (SEQI) is calculated by the weighted average of the standard values of the 18 indicators. The assessment model is then applied in evaluating soil quality of Hebei Province, China. The results show that the soil environmental quality of Hebei’s agricultural land is in a medium state, and the industrial land is approaching the alert state. The pressure of soil pollution mainly comes from the discharge of industrial pollutants and the application of pesticides and fertilizers. Soil pollutants, such as lead, copper, zinc, benzo[a]pyrene, and benzo[a] should be especially controlled.

Soils and plants of Saint Petersburg are under the constant technogenic stress caused by human activity in industrial, residential, and recreational landscapes of the city. To assess the transformed landscapes of various functional zones, we studied utility, housing, and park districts with a total area of over 7,000 hectares in the southern part of the city during the summer seasons of 2016-2018. Throughout the fieldwork period, 796 individual pairs of soil and plant samples were collected.A complex of consequent laboratory studies performed in an accredited laboratory allowed the characterization of key biogeochemical patterns of urban regolith specimens and herbage samples of various grasses. Chemical analyses provided information on the concentrations of polluting metals in soils and plants of different land use zones.Data interpretation and calculation of element accumulation factors revealed areas with the most unfavorable environmental conditions. We believe that a high pollution level in southern city districts has led to a significant degree of physical, chemical, and biological degradation of the soil and vegetation cover. As of today, approximately 10 % of the Technosols in the study area have completely lost the ability to biological self-revitalization, which results in ecosystem malfunction and the urgent need for land remediation.
