“…How to eliminate the human impact and obtain the background value of heavy metals in soil are very important for the evaluation of soil pollution. Relative cumulative frequency and regression analysis are mainly used to constitute the heavy metal geochemical baseline in soils [5,6]. The relative cumulative frequency method was established in the 1990s, and then improved by domestic and overseas scholar.…”

To understand the content, pollution, distribution and source and to establish a geochemical baseline of heavy metal elements in soil under the influence of high-density population, the concentrations of heavy metal elements Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Hg, Pb and Fe were determined in 23 soil samples in Suzhou University, and geo-accumulation index, enrichment factor, principal component analysis, spatial analysis and regression analysis were completed. The results showed the following: The elements Cu and As were slightly polluted, while the other heavy metal elements were not. The elements Cd, Cu, Ni and As in soils were mainly caused by agricultural activities of chemical fertilizer, whereas the elements Zn and Hg were impacted by the chemicals and batteries. The heavy metal elements in the north were lower than in the south of the campus, as a whole. The enrichment of elements Cu, As and Cd was caused by the east–west river on the campus, and the enrichment of the elements Mn, Ni and Zn was induced by the reservoir. Biochemical experiments and vehicle parking influenced the spatial enrichment of Cr, Co and Pb, while domestic waste led to the spatial differentiation of Hg concentrations. The regression curve between heavy metal elements and Fe was established, and the background values of the heavy metals Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Hg and Pb are 50.90, 489.37, 11.76, 37.74, 55.70, 58.22, 20.07, 0.09, 0.08 and 24.13 mg/kg, respectively.

“…Artificially recharging an arseniferous aquifer by rain water or surface water [66,67], or injecting oxygenated water [68,69], have been found to drastically dilute and reduce the As(III) concentrations in the aquifers. But such a contamination regulation technique does not give much success, because of inadequate understanding of all the ecohydrological processes which govern the geochemical behaviour of these aquifer systems [28,70].…”

Globally, intrusion of toxic heavy metals into groundwater ecosystems has been a topic of serious concern for sustaining public health. Extracting contaminated subsurface waters for consumption as drinking water intake has led to catastrophic debilitations in populations, particularly those in rural areas of developing countries lacking robust municipal water-supply infrastructures [1]. Within this subject matter, mysterious and rampant geochemical release of arsenic in the subsurface waters of India (as depicted in Figure 1(a)) has impaired the concerted mitigation efforts of several geologists and environmental science researchers around the world. Arsenic (As) is a notorious carcinogen and its chronic intake causes incurable health problems [2,3].
