“…The high Cd loading of factor 2 may be associated with geological origin of the black shale in ESA. Rock weathering is a significant source of Cr in the environment. , Because the eluvial soils are formed mainly by in situ accumulation of rock weathering, the soils can easily inherit HMs from the bedrock. In addition, the As and Pb contents in the soils of ESA were similar to the local background values, indicating that As and Pb were likely mainly derived from the local geological background.…”

Heavy metals or metalloids (HMs) in agricultural soils at high geological background areas could inherit the characteristics of parent materials, which would affect HM accumulation in crops. However, the specific impact of different parent materials on the behavior of HMs was unclear. This study focused on the bioavailability and risk variations of HMs in paddy soils derived from eluvial and alluvial parent materials in the Xitiaoxi catchment based on the total concentration, fraction, and risk assessment of HMs. The results showed that the paddy soil in the alluvial area had a higher bioavailability and risk level of HMs than those in the eluvial area, due to the increased proportion of activated HMs in the alluvial paddy soil. The increase in activated HMs was associated with a decrease in soil acidity and fertility as well as intensified anthropogenic activities within the alluvial study area. The spatial distribution of HM risk in soil samples demonstrated that the risk level of HMs was related to the exposure of black shale in eluvial soil, while the risk level of HMs in alluvial soil was negatively correlated with distance from the riverside. The source apportionment results further indicated that the alluvial paddy soil had lower geological but higher anthropogenic sources, especially for Cd, Pb, and Cu. In summary, the alteration in the properties of parent materials during river transportation and more anthropogenic sources raised the bioavailability and risk of HMs in the alluvial paddy ecosystem. This study provided new insights into HM risk assessment and control in agricultural soils developed from different parent materials within a catchment with a high geological background.

“…Extensive research shows that heavy metals in soils are broadly influenced by natural background levels and anthropogenic activities. Natural sources include mainly parent material and weathering of rocks [ 10 , 11 ]. Anthropogenic activities include industrial emissions [ 12 ], mining and smelting activities [ 13 ], fertilizers and agrochemical application [ 12 ], sewage irrigation [ 14 ], sludge application [ 15 ] and vehicle exhaust [ 16 ].…”

Soil heavy metal contamination is crucial due to menacing food safety and mortal health. At present, with the fast advancement of urbanization and industrialization, heavy metals are increasingly released into the soil by anthropogenic activities, and the soil ecosystem contamination around the Danjiangkou Reservoir is directly associated with water quality security of the reservoir. In this paper, using 639 soil samples from the Danjiangkou Reservoir, Henan Province, China, we studied a variety of space distribution characteristics of heavy metals in soil. Geographic information system analysis (GIS), geo-accumulation index (Igeo), contamination factor (CF), principal component analysis (PCA) model, and positive matrix factorization (PMF) model were used together to recognize and quantify the distribution, contamination, and origin of heavy metals. We uncovered an exceptional variety of heavy metal concentrations among the tested soils: the mean arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), manganese (Mn), nickel (Ni), zinc (Zn), lead (Pb) and mercury (Hg) concentrations (14.54, 0.21, 18.69, 81.69, 898.42, 39.37, 79.50, 28.11, 0.04 mg/kg, respectively, in the topsoil (0–20 cm depth)), all exceed their background values. The mean Igeo value and CF values of these trace elements are both in descending order: Cd > Co > Mn > Ni > Pb > Zn > Cr > As > Hg. Cd was the highest contributor to the assessment of heavy metal pollution, with an average Igeo value over three, indicating that the study area is modestly contaminated by Cd. The PCA analysis and PMF model revealed three potential sources, including natural sources (PC1) for Cr, Co, Mn and Ni; agricultural sources (PC2) for Cd, Zn and Hg; and industrial emissions and transportation sources (PC3) for Pb. This study displays a map of heavy metal contamination in the eastern area topsoil of the Danjiangkou Reservoir, showing the most severe pollutant is Cd, which poses a threat to the water quality security of Danjiangkou Reservoir and provides a significant source identification for future contamination control.

“…Soil receives different types of metals (heavy metal, toxic element, trace element) coming from various sources (anthropogenic and lithogenic), increasing their natural content, thus reducing the soil quality. However, as a reservoir, the soil itself is abundant of metals transported from biomass, atmosphere, and hydrosphere (Gbadamosi et al 2018;Duan et al 2020), but when it exceeded the safe/threshold limit may provoking risk to human and ecosystem. Contamination of soil by metals becomes a prime concern worldwide, as heavy metals are non-degradable and affect the human body adversely.…”

Present study was sketched to estimate the level of heavy metals (Cr, Fe, Cu, Zn, As and Pb) in the industrially affected soil, their source apportionment, degree of pollution and estimation of probable health risk by direct soil exposure and via dietary intake of vegetables grown in the affected soil. Mean concentrations of Cr, Fe, Cu, Zn, As and Pb was found 61.27, 27274, 42.36, 9.77, 28.08 and 13.69 and 0.53, 119.59, 9.76, 7.14, 1.34 and 2.69 mg/kg for affected soil and vegetable samples, respectively. The origin of Fe, Cu, Zn and Pb were found lithogenic, while Cr and As were anthropogenic. A moderate enrichment was noted by Cr, As, and Pb in the entire sampling site, indicating a progressive depletion of soil quality. Bioaccumulation factor (BCF) value for all the vegetables were recorded BCF<1; however Metal pollution index (MPI) value stipulate a pretty high value in the vegetable samples. Health effect on account of direct exposure of contaminated soils manifested more hazardous than dietary intake of heavy metal contaminated vegetables and children were found more vulnerable receptors compare to adults. However, this study can be used as a reference towards similar types of study to evaluate heavy metal contaminated soil impact on the population of Bangladesh and other countries as well.
