“…It is estimated that, globally, more than 20 million hm 2 of land is contaminated with heavy metal(loid)s [1]. Particularly, heavy metals can enter agricultural soils via various pathways, such as atmospheric deposition, sewage irrigation, and applications of livestock manures and agricultural chemicals [2,3]. They can be taken up by crops and accumulated in edible parts, and they further pose potential health risks for humans and animals via the food chain [4,5].…”

Soil amendments have been proposed for immobilizing metallic contaminants, thus reducing their uptake by plants. For the safe production of crops in contaminated soil, there is a need to select suitable amendments that can mitigate heavy metal uptake and enhance crop yield. The present experiment compared the effects of three amendments, hydroxyapatite (HAP), organic manure (OM), and biochar (BC), on plant growth and heavy metal accumulation by maize in an acidic soil contaminated with Cd, Pb, and Zn, and their potential for safe crop production. Toxicity characteristic leaching procedure (TCLP) tests, energy dispersive X-ray spectroscopy (EDS) analysis, and X-ray diffraction (XRD) analysis were used to evaluate the effectiveness and mechanisms of heavy metal immobilization by the amendments. The results showed that shoot and root biomass was significantly increased by HAP and 1% OM, with an order of 1% HAP > 0.1% HAP > 1% OM, but not changed by 0.1% OM and BC (0.1% and 1%). HAP significantly decreased Cd, Pb, and Zn concentrations in both shoots and roots, and the effects were more pronounced at the higher doses. OM decreased the shoot Cd and Pb concentrations and root Zn concentrations, but only 1% OM decreased the shoot Zn and root Pb concentrations. BC decreased the shoot Cd and Pb concentrations, but decreased the shoot Zn and root Pb concentrations only at 1%. HAP decreased the translocation factors (TFs) of Cd, Pb, and Zn (except at the 0.1% dose). OM and BC decreased the TFs of Cd and Zn, respectively, at the 1% dose but showed no significant effects in other cases. Overall, plant P, K, Fe, and Cu nutrition was improved by HAP and 1% OM, but not by 0.1 OM and BC. Soil pH was significantly increased by HAP, 1% OM, and 1% BC, following an order of 1% HAP > 1% OM > 0.1% HAP > 1% BC. The TCLP levels for Cd, Pb, and Zn were significantly reduced by HAP, which can be partly attributed to its liming effects and the formation of sparingly soluble Cd-, Pb-, and Zn-P-containing minerals in the HAP-amended soils. To some extent, all the amendments positively influenced plant and soil traits, but HAP was the optimal one for stabilizing heavy metals, reducing heavy metal uptake, and promoting plant growth in the contaminated soil, suggesting its potential for safe crop production.

“…Recent research on agricultural soils revealed the accelerated accumulation of heavy metals and associated health risk, especially due to greenhouse agricultural cultivation (Wan et al 2019) and the usage of fertilizers and fungicides (Huang et al 2019). Moreover, high impact of PHEs contamination on soils via atmospheric deposition is mainly generated by coal combustion (Peng et al 2019) that in Poland is very common. Exceedance of regulation limits concerning PHEs content was observed in soils that are adjacent to megalopolises, large motorways and industrial enterprises (Barsova et al 2019).…”

Agricultural soil samples were collected from the areas where edible plants had been cultivated in southern Poland. The PHE content decreased in proportion to the median value specified in brackets (mg/kg d.m.) as follows: Zn (192) [ Pb (47.1) [ Cr (19.6) [ Cu (18.8) [ Ni (9.91) [ As (5.73) [ Co (4.63) [ Sb (0.85) [ Tl (0.04) [ Cd (0.03) [ Hg (0.001) [ Se (\ LOQ). No PHE concentrations exceeded the permissible levels defined in the Polish law. The PHE solubility (extracted with CaCl 2) in the total concentration ranged in the following order: Fe (3.3%) [ Cd (2.50%) [ Ni (0.75%) [ Zn (0.48%) [ Cu (0.19%) [ Pb (0.10%) [ Cr (0.03%). The soil contamination indices revealed moderate contamination with Zn, ranging from uncontaminated to moderately contaminated with Pb, and, practically, no contamination with other PHEs was identified. The ecological risk indices revealed that soils ranged from uncontaminated to slightly contaminated with Zn, Pb, As, Cu, and Ni. The PCA indicated natural sources of origin of Co, Cu, Hg, Sb, Zn, Cr, and Pb, as well as anthropogenic sources of origin of Cd, Ni, As, and Tl. The human health risk assessment (HHRA) for adults and children decreased in the following order of exposure pathways: ingestion [ dermal contact [ inhalation of soil particles. The total carcinogenic risk values for both adults and children were at the acceptable level under residential (1.62E-05 and 6.39E-05) and recreational scenario (5.41E-06 and 2.46E-05), respectively, as well as for adults in agricultural scenario (1.45E-05). The total noncarcinogenic risk values for both adults and children under residential scenario (1.63E-01 and 4.55E-01, respectively), under recreational scenario (2.88E-01 and 6.69E-01, respectively) and for adults Electronic supplementary material The online version of this article (

“…Livestock feed generally contained Cu and Zn additives to prevent disease, but the Cu and Zn cannot be fully absorbed by livestock (Lu et al, 2012). Cu derived from livestock manures accounted for 76% of the total Cu inputted into farmland (Peng et al, 2019). Lu et al (2012) concluded that livestock manures contained high Cu and Zn concentrations.…”

Soil heavy metals (HMs) pollution has caused significant land degradation by affecting soil properties and functions. Clarifying sources and spatial distributions of soil HMs is necessary for the investigation of land degradation, but lacks accurate and efficient methods. This study proposes a combined method for improving source apportionment and spatial prediction of soil HMs. Finite mixture distribution modelling (FMDM) was used to explore the backgrounds and contamination thresholds, and can verify the source contribution calculated by positive matrix factorization (PMF). To improve the efficiency of traditional multivariate geostatistical simulation, independent component analysis and sequential Gaussian simulation were integrated into geostatistical independent simulation for revealing the spatial patterns and the polluted areas. The combined method was applied to an HMs dataset of Longkou City, eastern China as a case-study. Both PMF and FMDM produced three sources of HMs. Cr and Ni were dominated by natural sources. Agricultural inputs mainly affected Cd, Cu, and Zn concentrations. Hg, 66.8%, and Pb, 8.1%, originated from industrial, mining, and traffic emissions. Hazardous areas exceeding moderate pollution cutoffs comprised 203.88 km 2 , accounting for 23.2% of the study area. Less than 0.1% of the areas for all HMs were identified as hazardous zones exceeding the high pollution thresholds. The reasonable management of industrial and agricultural activities, traffic emissions, and mining could have an important influence on the protection of land resources. Combining FMDM, PMF, and geostatistical independent simulation proved valid for investigating the land degradation due to HMs pollution.
