“…In this study, the CR of Cr was slightly higher than that of As (Table 4). Studies have shown that long-term exposure to low-dose concentrations of Cr will have toxic and carcinogenic effects on human body (Angelone & Udovic, 2014). Wuwei farmland soil was more polluted by Cr (Figure 2a), and the SF value of Cr was higher under the ingestion pathway, so Cr had higher CR for adults and children (Table 4).…”

Source identification and risk assessment of heavy metals are ongoing hot topics in current research, but few studies have been performed on the linkage mechanism between them. In the past, the amount of heavy metals discharged was the identification criterion for high-risk source but failed to consider different toxicity of heavy metals in the risk level of each pollution source. Therefore, it is impossible to accurately determine high-risk pollution source. For this situation, this study introduced a risk assessment model based on the source apportionment model, which can quantitatively analyze the source-based risk. Meanwhile, pollution assessment indexes and a risk assessment model were applied to evaluate the levels of pollution and risk of heavy metals, showing that lead (Pb) caused relatively serious pollution and arsenic (As) generated the highest ecological risk and noncarcinogenic risk. Positive matrix factorization (PMF) model identified and quantified the sources of heavy metals (coal-related activities source, mixed source of mining and traffic emissions, industrial activity source, agricultural source related to the application of agrochemicals) with the corresponding contributions of 42, 30, 26, and 2%, respectively. Then PMF was combined with potential ecological risk index and human health risk assessment model to quantify the risk from pollution sources, indicating that the coal-related activities source was the largest pollution source (31-36%) that caused human health risks, while the mixed source of mining and transportation emissions posed the greatest threat (29%) to the ecosystem health. Therefore, both sources should be identified as the priority pollution sources.

“…Während einige Grundlagenuntersuchungen zu städtischen Böden vorliegen (Grenzius 1987, Hiller & Meuser 1998, ist deren Bezug zur Gesundheit in Städten bisher nur wenig beleuchtet worden (Angelone & Udovic 2014). Positive Auswirkungen könnten hierbei unversiegelte und biologisch aktive Böden im Hinblick auf das Mikroklima, die städtischen Wasser-und Nährstoffkreisläufe und das Naturerleben haben, negative Auswirkungen ergeben sich durch kontaminierte Stadtböden bzw.…”

“…As one of the most important components of the urban ecosystem, soil provides a growing medium, habitat, and nutrients for plants and soil microbes. It also serves as an important sink for urban pollution, helping to absorb, degrade, and reduce levels of pollutants (Sheng et al 2012;Ayrault et al 2013;Rota et al 2013;Angelone and Udovic 2014). Human activities, however, have seriously affected the overall quality of soil and changed its physical and chemical conditions.…”

Accumulation of heavy metals in agricultural land and their ecological risks are key issues in soil security studies. This study investigated the concentrations of six heavy metals-copper (Cu), zinc (Zn), lead (Pb), nickel (Ni), and chromium (Cr) in Shenzhen's agricultural lands and examined the potential hazards and possible sources of these metals. Eighty-two samples from agricultural topsoil were collected. Potential ecological risk index was used to calculate the potential risk of heavy metals. Principal component analysis (PCA) was applied to explore pollution sources of the metals. Finally, Kriging was used to predict the spatial distribution of the metals' potential ecological risks. The concentrations of the heavy metals were higher than their background values. Most of them presented little potential ecological risk, except for the heavy metal cadmium (Cd). Four districts (Longgang, Longhua, Pingshan, and Dapeng) exhibited some degree of potential risk, which tended to have more industries and road networks. Three major sources of heavy metals included geochemical processes, industrial pollutants, and traffic pollution. The heavy metal Cd was the main contributor to the pollution in agricultural land during the study period. It also poses the potential hazard for the future. High potential risk is closely related to industrial pollution and transportation. Since the 1980s, the sources of heavy metals have evolved from parent rock weathering, erosion, degradation of organics, and mineralization to human disturbances resulting in chemical changes in the soil.
