Summary: In this study, a method for the analysis of trace metals in seawater was developed and validated. The method utilizes a seaFAST solid-phase extraction device, triple quadrupole collision/reaction technique with ICP-MS, and isotope dilution technique for quantification. The results were consistent with reference values and demonstrated good oceanic consistency.

Summary: This study explored the activation effect of oxalic acid on bone meal (BM) and developed an oxalic acid-activated bone meal (ABM) for improving heavy metal immobilization efficiency. The results showed that ABM had higher solubility and outperformed BM in terms of immobilizing lead (Pb) and cadmium (Cd). The leaching concentration of Pb from ABM immobilized soils met regulatory limits and was significantly lower than that from BM immobilized soils. After 90 days of curing, ABM also showed better Cd immobilization performance than BM.

Summary: The study evaluated the capability of native plant species grown in polluted post-mining soils to accumulate metals for phytoremediation. Different native plants were found suitable for remediation of specific metals, with some being effective for both Cd and Zn. However, none of the studied plants were suitable for phytoremediation of Pb, Cu, As, and Ag.

Summary: The study used scattered literature to summarize the effects of excessive Cd, As, and Pb from contaminated soils on plant secondary metabolites/bioactive compounds. The study provided a systematic overview of the sources and forms of these risk elements in soils, their uptake by plants, the mechanisms governing their interaction during the formation of secondary metabolites, and the subsequent effects. The biogeochemical characteristics of soils and the translocation mechanisms in plants play crucial roles in risk element accumulation and the impact on secondary metabolites.

Summary: This study investigated the effects of organic amendments on microbial activity and bioavailability of toxic metals in soils contaminated by wastewater irrigation. The results showed that organic amendments can enhance microbial activity, reduce the bioavailability of toxic metals, and improve overall soil quality in wastewater irrigated soils.

Summary: The study investigated the long-term dynamics of trace elements in agricultural fields using dynamic simulations, focusing on the effects of different organic amendments on soil concentrations. The results showed that dissolved organic carbon fluxes play a key role in estimating labile metal concentrations, with cadmium being particularly sensitive to this factor.

Summary: A method using DGT was developed for accurate quantification of trace-level Sr and Pb concentrations and isotope ratios in soils. The method utilizes a novel PTFE membrane binding layer with high selectivity for Sr and Pb. The study showed that the method performed well under various conditions and selective elution process allowed for purification of Sr and Pb fractions.

Summary: This study investigated the efficiency of using fulvic acid (FA) for removing lead (Pb) and cadmium (Cd) from polluted soil using Tagetes eracta L. and Zinnia elegans Jacq ornamental plants. The results showed that FA application increased plant growth, decreased heavy metal accumulation, and reduced oxidative stress in the plants. Therefore, FA can be recommended for stabilizing Pb and Cd in polluted soil.

Summary: This study investigated the sorption of Pb, Cd, and Cu in five natural soils of Nigerian origin and compared the predictive performance of the adaptive neuro-fuzzy inference system (ANFIS) and multiple linear regression (MLR) models. The results showed that ANFIS outperformed MLR in predicting the adsorption capacities of the soil-metal ion systems.

Summary: Soils pollution with heavy metals (HMs) is a serious concern, and this study focused on the remediation of cadmium (Cd) and lead (Pb)-contaminated soils using chemical and physical techniques. The application of stabilizers such as calcium carbonate, dolomite, zeolite, and steel slag significantly reduced the uptake of Cd and Pb by Chinese cabbage plants. These stabilizers also decreased the exchangeable and carbonates bound fractions of Cd and Pb in the soil. The results demonstrated that in-situ chemical remediation techniques showed promising and long-lasting results.

Summary: This study analyzed the speciation, bioavailability, and human health risk of toxic heavy metals in urban soils of a heavy industrial city in NE China. The results showed that concentrations of Arsenic (As), Mercury (Hg), Lead (Pb), and Cadmium (Cd) in the soil all exceeded the background value of the study area. Mercury displayed the highest pollution level, followed by Cd, Pb, and As. The study also found that using bioavailable fraction for health risk assessment provided more reliable results.

Summary: Polluting activities have a significant impact on agricultural lands, and the use of hemp in phytoremediation shows promise in managing metal polluted soils. This study conducted in Sardinia, Italy, aimed to evaluate the phytoremediation capability of industrial hemp in metal polluted soils under semiarid environments. The results showed that concentrations of Zn and Cd in the plants were positively correlated with soil content and varied in different parts of the plants. The study also found high levels of Pb in plants grown in non-contaminated soils, possibly due to atmospheric deposition from distant sources.
