“…In a review of Indian agricultural soils, values for metals Co, Cr, Ni and V were mostly lower than the values found in this work [26]. Additionally, analysis of the agricultural soils from the Shanghai region found an average Cr value of 41.00 mg/kg [27] and showed that although this region is highly industrialized, the heavy metal levels in agricultural soils were within safe ranges according to the Chinese environmental regulations.…”

Agriculture is the main economic activity of Mozambique and there is a lack of information about the quality of agricultural soils. In this paper, five soils from the Manica and Sussundenga districts (Manica province) sampled in the years 2021/2022 and 2022/2023 (before and after the rainy seasons) were subjected to an agronomical and environmental chemical analysis to assess their quality, from the fertility and environmental contamination points of view. Standard analytical methodologies from external certified laboratories and local X-ray fluorescence measurements were used. All the studied soils were acidic (pH ranging from 4.5 to 5.4), had no salinity problems (conductivity ranging from 4.2 to 11.8 mS/m), and had a low amount of soil organic matter (0.90% to 1.81%). Soils from the Sussundenga district had a very low cation exchange capacity (CEC) (average of 3.33 cmolc/kg), while that of those from the Manica district ranged from very low to average CEC (3.59 to 13.11 cmolc/kg). Sussundenga soils also had a phosphorous deficiency (values ranging from <20 to 38.5 mg/kg) and there were deficiencies and/or excesses of some macro and micronutrients in all soil samples. Manica soils were contaminated, apparently from geogenic origin, with Cr (280 to 1400 mg/kg), Co (80 mg/kg), Ni (78 to 680 mg/kg) and V (86 mg/kg). Agricultural soil monitoring must be fostered in Mozambique in order to improve food quality and quantity to ensure economic and environmental sustainability.

“…The accumulation of heavy metals in the soil exceeds the maximum plant demand and tolerance, showing symptoms of toxicity or plant growth is not harmed, but the excessive content of certain metals in the harvest causes human and animal injury [5]. The main sources of heavy metal pollution can be divided into two categories: man-made and natural sources.…”

Soil is the solid foundation for our survival and development. With the progress of society, our country pays more and more attention to soil pollution. Soil pollution can cause the quality and yield of agricultural products to decline, pollute groundwater and surface water resources, affect air quality, lead to soil pollution in regional areas, and cause the destruction of ecological environment and the sharp decline of biodiversity. These problems will affect China's future sustainable development and social stability, so a detailed analysis of the sources of soil pollution is conducive to analyzing the nature of pollutants and pollution methods, which plays an important role in the prevention and control of soil pollution. And to introduce to the public some new technologies of soil pollution control, new ideas and the future direction of soil remediation.

“…The contamination of agricultural soils by heavy metal(oid)s has drawn significant global attention due to their toxicity, persistent and non-biodegradable nature. In addition, human activities also substantially exacerbate heavy metal(oid) contamination [ 6 , 7 , 8 , 9 ]. In fact, heavy metal contamination contributes significantly to the deterioration of soil quality and environmental health [ 10 , 11 , 12 ].…”

Soil pollution caused by heavy metal(oid)s has generated great concern worldwide due to their toxicity, persistence, and bio-accumulation properties. To assess the baseline data, the heavy metal(oid)s, including manganese (Mn), iron (Fe), Cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), lead (Pb), mercury (Hg), chromium (Cr), and cadmium (Cd), were evaluated in surface soil samples collected from the farmlands of Grand Forks County, North Dakota. Samples were digested via acid mixture and analyzed via inductively coupled plasma mass spectrometry (ICP MS) analysis to assess the levels, ecological risks, and possible sources. The heavy metal(oid) median levels exhibited the following decreasing trend: Fe > Mn > Zn > Ni > Cr > Cu > Pb > Co > As > Cd > Hg. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) suggested the main lithogenic source for the studied metal(oid)s. Metal(oid) levels in the current investigation, except Mn, are lower than most of the guideline values set by international agencies. The contamination factor (Cf), geo accumulation index (Igeo) and enrichment factor (EF) showed considerable contamination, moderate contamination, and significant enrichment, respectively, for As and Cd on median value basis. Ecological risk factor (Er) results exhibited low ecological risk for all studied metal(oid)s except Cd, which showed considerable ecological risk. The potential ecological risk index (PERI) levels indicated low ecological risk to considerable risk. Overall, the results indicate the accumulation of As and Cd in the study area. The high nutrients of the soils potentially affect their accumulation in crops and impact on consumers’ health. This drives the impetus for continued environmental monitoring programs.
