“…In this study area, the mean concentrations of Pb, Cd, As, Cu, Zn (542, 5, 369, 362, and 65 mg/kg, respectively) in soil samples exceed the Chinese Risk screening values of agricultural soil (120, 0.3, 30, 250, and 100 mg/kg, respectively). These values also exceed the standard of the world guidelines recognized by World Health Organization (WHO) limit Pb, Cd, Cu, Zn (20, 0.3, 4, and 50 mg/kg) [22]. However, the detected values for Pb and Cd from this study area are lower than the concentrations measured for the soil near the Chenzhou mine.…”

“…In this paper, all soil samples in this study were yellow soil with pH values ranging between 6.5 and 7.5. It is necessary to compare the results obtained in our study with other studies that were applied in agricultural soils from different regions, so as to evaluate heavy metals in agricultural soils reasonably [22]. A previous report indicated that the background values of Pb, Cs, As, Zn, and Cu in Hunan were 29.7, 0.126, 15.7, 94.4, 27.3 mg/kg, respectively, which are obviously higher than those reported for the entire country (27.3, 0.079, 13.6, 88.6, 25.4 mg/kg, respectively) [23].…”

To understand the heavy metal pollution in agricultural soils along the East River basin and assess the pollution related health effect to local residents, interviews and archived data were obtained to identify the study sites affected by polluted tailing. Soil samples were collected and tested for heavy metal content and the Comprehensive Pollution Index (CPI). The degree of pollution of agricultural soils in the area was assessed using GIS-based Spatial distribution map of heavy metals and the trend of soil heavy metal risk. Two villages (Matian and Zhudui) near the East River were included in this study for health effect assessment. A total of 193 residents aged 15 or above from each village were tested for the present status of chronic diseases. Convenient sampling method was used to collect blood samples from 78 residents for heavy metal concentration. The contents of Pb, Cd, As, Zn, and Cu in the agricultural soils were all over the standards with a moderate to severe CPI. Among these metals, Cd was the highest followed by Pb, and Cu was the lowest. The contents of Pb, Cd, As, and Zn tend to be higher in soils closer to the river. The prevalence of chronic diseases was over 30%, which is significantly higher than the report from the national central region (23.15%). The average blood lead level (BLL) among children under 14 years is 7.42 µg/dL. Although the adults in Matian village had a significantly higher BLL (χ 2 = 8.70, p = 0.03) as compared to Zhudui village, there was no significant difference for the prevalence of chronic diseases between the two villages (χ 2 = 3.23, p = 0.09). The mean BLL of children and the proportion of children with BLL ≥ 10 µg/dL in this study are equivalent to the national average. The higher BLL concentration and prevalence of chronic diseases in adults might be due to their long-term exposure to heavy metal contamination environment and higher background level of heavy metals. Findings from this study will form the baseline information for local government to the development of effective approaches to control the heavy metal contamination and reduce the pollution related adverse health effect on local residents.

“…The soil pollution is found in many countries, for example, in USA over 100,000 sites have deteriorated soil due to pollution (He et al 2015), while in China 3.33 million hectares of arable land are highly contaminated (Chen and Ye 2014). Nevertheless, Morocco is currently facing serious problems of contamination by metals (El Baghdadi et al 2012;Oumenskou et al 2018;Ennaji et al 2018a; Barakat et al 2019c). The main source of soil pollution in Morocco is human activities that have raised several questions about the constant changes in soil properties and the accumulation of pollutants in soils (Barakat et al 2017(Barakat et al , 2019aEnnaji et al 2018b;Oumenskou et al 2018), which consequently affect soil quality, as a result of local and global climate change (Pielke 2005).…”

Moreover, heavy metals content can be affected by interactions of soil physicochemical properties such as soil pH, grain size, (Błońska et al 2016;Gąsiorek et al 2017) and organic matter content, heavy metal accumulation capacity, which play an important role in the retention, mobilization, and migration of heavy metals in soil (Weber et al 2018).…”

The present study investigated the potentially toxic heavy metal (Cu, Pb, Zn, Cr, and Cd) contamination and its ecological impact in the agricultural soil in the northeast part of Tadla plain (Morocco). A total of 60 subsurface composite samples were collected and analyzed to determine pH, soil organic matter (SOM) and texture, and heavy metal concentrations. Pollution levels were assessed by adopting enrichment factor (ef), geoaccumulation index (I geo), contamination factor (CF), pollution load index (PLI), and ecological risk index (RI). The results showed that the average concentrations of Cd, Cr, Cu, Pb, and Zn in the collected 60 topsoil samples were 0.92, 32.72, 138.10, 31.72, and 162.11 mg/kg, respectively, and followed the order Zn > Cu > Cr > Pb > Cd. These concentrations exceeded acceptable thresholds of the World Health Organization (WHO) and Food and Agriculture Organization (FAO) and local background. From the Principal Component Analysis (PCA) results showing no correlation between the soil properties and heavy metal contents, suggesting that the metal elements were of different sources, especially anthropogenic. The mean RI values of 65.68 indicated a low ecological risk and indicate that the study area is moderately to strongly pollute in the case of Zn and Cu and partly influenced by human activities. Nevertheless, this study provided important information for policymakers to propose an appropriate plan for pollution control in the agricultural Tadla plain.

“…Opinions amongst respondents on whether or not pollution of soils, groundwater or natural environment occurs, vary. There is research from Morocco showing nitrogen pollution from agriculture and to a lesser extent pesticides in some of the more intensively farmed areas in Morocco (Fetouani et al, 2008;Malki et al, 2017;Oumenskou et al, 2018) -no specific study for potatoes cultivation however was found.…”
