Summary: The application of amendments effectively reduced the bioavailability of Cd in soil, with oyster shell powders increasing soil richness and limestone increasing microbial diversity. However, limestone altered the soil microbial community structure while oyster shell powders maintained it. The study also found that pH, TN, TP, CEC, and OM were the dominant factors affecting the microbial community.

Summary: Soil acidification in the subtropical region reduces soil productivity and increases the bioavailability of heavy metal(loid)s in soil. This study aimed to remediate an acidic soil contaminated by cadmium (Cd) and arsenic (As) using a Ca-humic complex formed from 800 degrees C-calcined oyster shell and leonardite-derived humic substance, for safe vegetable production. Results showed that a 2.0% dose of the complex significantly reduced Cd and As contents in vegetables, reducing the human health risk. The complex also lowered the bio-accessibility of Cd and As in soil, reducing the human health risk from soil ingestion. The use of oyster shell waste to produce Ca-humic complex as a soil amendment has agronomic and environmental benefits.

Summary: This study found that oyster shell amendment can reduce the concentration of cadmium and lead in soil, while significantly increasing the pH of soil and pore water. The use of appropriate oyster shell amendment and selection of suitable rice cultivars can simultaneously reduce the accumulation of heavy metals in rice.

Summary: The application of waste oyster shell powder (OSP) in agriculture can improve rice yields and reduce cadmium (Cd) accumulation in all tissues, especially in grains. OSP supplementation increases pH and reduces the phytoavailability of Cd in soil. It also promotes the dissolution of Ca, Fe, Zn, and Se. In hydroponics, OSP can suppress Cd accumulation in rice by inhibiting the expression of genes responsible for Cd absorption and xylem loading.

Summary: This study investigates the viability of using oyster shell (OS) in ocean engineering, focusing on the impact of calcination temperature of OS powder on the properties of eco-friendly waste OS mortar. The study also evaluates the cost-efficiency and eco-efficiency of OS mortars. The experimental findings reveal that the strength development of OS mortar follows similar patterns to other types of mortars. The addition of OS powder significantly improves the mechanical properties, microstructure, water resistance, and chloride diffusion properties of OS mortar, but slightly decreases its workability. The calcination temperature of OS powder affects the properties, cost-efficiency, and eco-efficiency, with the strongest impact observed at temperatures close to 900 degrees C. The optimal calcination temperature of OS powder is determined as 950 degrees C, resulting in reduced CO2 emissions and raw material costs, as well as improved eco-efficiency and cost-efficiency.

Summary: Liming acidic paddy soils to near-neutral pH is the most cost-effective strategy to minimize cadmium (Cd) accumulation by rice. However, the effect of liming on arsenic (As) (im)mobilization is still controversial and warrants further investigation, especially for paddy soils co-contaminated with As and Cd. This study explored As and Cd dissolution along pH gradients in flooded paddy soils and identified the relative availability of Fe under competition from dissolved organic carbon (DOC) as a key factor. The mole ratio of porewater Fe/DOC at pH 6.5-7.0 is suggested as an indicator of whether co-immobilization of As and Cd can occur in limed paddy soils.

Summary: In this study, the application of biochar and oyster shell was found to reduce the accumulation of cadmium in crops and improve soil quality. The addition of biochar and oyster shell decreased the HOAc-extractable Cd in soil and reduced Cd accumulation in brown rice and oilseed, while increasing soil organic matter and available phosphorus. Furthermore, the cooperative application of biochar and oyster shell enhanced enzyme activities in the soil.

Summary: The study suggests that mantle tissue in oysters can maintain biomineralization under ocean acidification conditions, with normal shell growth and mechanical properties. Ocean acidification is more of a 'dissolution problem' rather than a 'biomineralization problem' for resilient species.

Summary: This study successfully synthesized a novel modified gangue material (MGE) from coal gangue and applied it to immobilize cadmium in contaminated soil. The results showed that the MGE had a large number of active groups on the surface, which facilitated the removal of Cd2+. Adsorption kinetics and isotherm models indicated that the adsorption behavior followed pseudo second-order and Langmuir models. Pot experiments demonstrated that the application of MGE significantly improved plant growth and reduced the content of available Cd2+ in the soil.

Summary: The study developed a remediation scheme by adding HDTMA-modified zeolite to mining site soil, which effectively improved soil organic matter content, increased the residual fraction of arsenic, and reduced the toxicity-related fraction, while also enhancing the oxidizable fraction of cadmium. The treatment with HDTMA-modified zeolite helped to improve soil microbial environment and reduce the bioavailability of arsenic and cadmium.

Summary: This review explores the potential of efficient slag recycling in agriculture and evaluates its impacts on crop yield, greenhouse gas emissions, heavy metal pollution, and environmental concerns. The study found that slag fertilization can effectively increase crop yield, reduce greenhouse gas emissions, and decrease the global warming potential. However, there is inconsistency in the accumulation of heavy metals in the soil and their uptake by plants through slag application.

Summary: Livestock manure application significantly increased NH3 volatilization rates, especially during the initial and additional fertilization stages in rice cultivation. Swine manure exhibited much higher volatilization rates than cattle manure, attributed to its higher labile NH4+ concentration and urease activity. NH3 emission rates proportionally increased with application levels in swine manure, but not in cattle manure.
