“…Positive correlations of Cu and Zn were reported with EC and TDS, which could be due to their use in the tanneries during hide processing [3]. The significant correlation of Cu and Zn with many of the soil properties could be due to their high mobility, as, Antoniadis and Golia [27] also reported that even small changes in soil parameters can affect mobility of these metals. Soil particle size and proportion have significant impacts on metal accumulation [38].…”

“…OM, TDS, and EC concentrations were 0.09-0.57%, 40-280 ppm and 0.07-0.41 mS cm −1 , respectively. Such low concentrations of OM may be the result of intensive agricultural practices and rapid mineralization in these soils under hot and humid conditions [2,27]. TDS are comprised of inorganic salts and EC is the measure of these salts.…”

This study was designed to investigate heavy metals concentrations in the suburban agricultural soils with particular emphasis upon their risk assessment. Therefore, a total of 36 collected soil samples were investigated for heavy metals analysis by atomic absorption spectrophotometer. The results showed that the mean concentrations were 126.8 mg kg −1 , 83.1 mg kg −1 and 118.5 mg kg −1 for Cr, Ni, and Pb, respectively, higher than the Canadian and European Union permissible limits of metals in agricultural soils; while the concentrations of Co, Cu and Zn were 34.7 mg kg −1 , 21.36 mg kg −1 and 92 mg kg −1 , respectively, within permissible limits, and were higher than guideline values at some sites. However, enrichment factors showed a substantial anthropogenic input of the studied metals. A significant to very high enrichment was recorded for Pb. Moreover, the geo-accumulation index revealed that these soils were moderately polluted with Pb. In general, pollution load index indicated moderate pollution of soils, which was mainly caused by Pb. The correlation and principal component analyses revealed that traffic emissions, tanneries, municipal waste and automobiles repair workshops were the predominant sources of Pb, Cr, Ni and Co; whereas Cu and Zn are of geogenic origin in agricultural soils of Sialkot.

“…4 and 5 show that the pH obviously increased with increasing HAP in the soils, and the DTPA-extracted Cd decreased. The micro-nanometer HAP can increase the soil pH to reduce the availability of heavy metals 34 . This result is consistent with some reports 27,35,36 .…”

the remediation of heavy metal-contaminated soils has attracted increased attention worldwide. The immobilization of metals to prevent their uptake by plants is an efficient way to remediate contaminated soils. this work aimed to seek the immobilization of cadmium in contaminated soils via a combination method. Flask experiments were performed to investigate the effects of hydroxyapatite (HAp) and the Cupriavidus sp. strain ZSK on soil pH and DtpA-extractable cadmium. pot experiments were carried out to study the effects of the combined amendment on three plant species. The results showed that HAP has no obvious influence on the growth of the strain. With increasing concentrations of HAp, the soil pH increased, and the DtpA-extractable cd decreased. Via the combined amendment of the strain and HAP (SH), the DTPA-extractable Cd in the soil decreased by 58.2%. With the combined amendment of the SH, the cadmium accumulation in ramie, dandelion, and daisy decreased by 44.9%, 51.0%, and 38.7%, respectively. Moreover, the combined amendment somewhat benefitted the growth of the three plant species and significantly decreased the biosorption of cadmium. These results suggest that the immobilization by the SH combination is a potential method to decrease the available cadmium in the soil and the cadmium accumulation in plants. Soil is the main sink for metals and acts as a barrier to prevent their entry into the food chain 1. However, human activities such as mining and metal smelting have gradually transferred many toxic metals from the earth's crust to the environment, resulting in the spread and contamination of heavy metals 2-4. In recent decades, heavy metal pollution has become a serious problem worldwide. In China, it was reported that 13.33% of all soil samples collected from 6.3 million square kilometres of land were polluted with high levels of metals 5. Cadmium pollution has been detected in all agricultural areas. Cadmium is chemically stable and does not undergo chemical or microbial degradation. Moreover, cadmium is not an essential element for living organisms. Generally, it is regarded as the most toxic among heavy metals 6. Cadmium in the soil harms plant cells by altering metabolic pathways, damaging chloroplasts and mitochondria, and causing oxidative damage to lipids and proteins 7,8 , and cadmium also interferes with the uptake and transport of essential elements, e.g., P and K 9. Excessive Cd can reduce iron uptake by plants, affecting their photosynthesis 10. Cadmium can also accumulate in plants and animals and thus enters the human body through the food chain, threatening health 11,12. Thus, it is an enormous challenge to remediate heavy metal-contaminated soils worldwide. Various physical, chemical and biological techniques have been used to remediate heavy metal-contaminated soils 1. In situ immobilization is generally considered a feasible technique to remediate metal-contaminated soils due to its cost effectiveness and ease of operation 13. Many researchers have reported on the use of various...

“…Cu was rather sorbed by the soil mineral components in this case. Antoniadis et al (2015) showed that soil organic compounds are capable of affecting Cu retention only when their amount is higher than a threshold. This was also found by synchrotron-based microscopic studies of Yang et al (2014), who found that Cu is associated with Feoxides in mine soils with low concentrations of organic matter.…”

Purpose. Heterogeneity of soil mineral particles may lead to the misinterpretation of bulk sorption data on their role in metal sorption, which may be resolved through the direct observation of metal distribution among the soil particles after the sorption. Materials and methods. Analytical transmission electron microscopy was used to study metal (Cd, Cu, Pb, Zn) sorption characteristics of clay minerals, Fe-oxyhydroxides and their natural assemblages in soils with contrasting pH under single element and competitive situations. Results and discussion. Iron-oxyhydroxides sorbed higher metal amounts than clay mineral particles mostly, and the sorption capacity of the latter phases were more affected by competition. Iron-oxyhydroxide particles acted as effective metal sorbents in soils not only as individual particles but also as coatings on other mineral particles, and the structural Fe in clay minerals may also resulted in higher metal sorption in some cases. Besides the direct observation of metal sorption onto soil mineral particles, metal precipitates could be identified directly, and the role of organic surfaces in metal sorption could be inferred indirectly in certain cases. Conclusions. Comparison of metal affinity sequences and their partition characteristics between the bulk soil and different mineral particles were found to be an effective tool to specify the most active mineral components in metal sorption at given soil and sorption condition.
