Summary: The use of organic amendments in horticulture and vegetable cultivation in urban areas is increasing. This can lead to increased risk of human exposure to potentially toxic elements from contaminated soils and compost. Co-application of biochar and compost can decrease the uptake of metals by edible plants, but may also have some adverse effects.

Summary: According to the Scopus database, there have been 91 scientific papers published in indexed journals in the domain of environmental science and agricultural science over the last five years that discuss the use of pXRF (portable X-ray fluorescence) technique. This indicates an increasing application of this technique in scientific research. The aim of this research was to analyze the metal content in commercial mineral nitrogen fertilizers using the pXRF method. The results showed that complex fertilizers had higher amounts of certain metals compared to single-component fertilizers, and the pXRF method was more suitable for the detection and quantification of metals in complex fertilizers.

Summary: Appropriate high doses of copper and zinc additives have beneficial effects on the antioxidant status and immune function of weaned piglets. Additionally, the addition of zinc and copper to the diet not only increases the concentration of corresponding trace elements in the serum, but also affects the concentration of other trace elements. Adjusting the copper and zinc content in the diet can help reduce the copper and zinc content in feces.

Summary: This study investigated the bioavailability of trace elements (TEs) and the effect of supplementation on anaerobic digestion of chicken manure leachate. The results showed low bioavailability of certain TEs, but supplementation improved their bioavailability and methane production efficiency. Scrutinizing the bioavailability and absolute concentrations of available TEs is critical for assessing the risk of TEs deficiency.

Summary: Urine is a nutrient-rich stream, containing high concentrations of nitrogen and phosphorus. Recovering these nutrients from urine is more efficient than from diluted wastewater. The recovered nutrients can be used as biomass for various purposes. This study found that the cyanobacterium Synechocystis sp. PCC6803 can effectively recover nitrogen and phosphorus from source-separated urine, with no negative effects on its growth.

Summary: Bauxite residue (red mud), an industrial byproduct, contains valuable trace elements that can be selectively leached using microwave heating, with or without the addition of solid NH4Cl as a chlorinating agent. The presence of solid NH4Cl during microwave heating helps convert trace elements into soluble metal chlorides, increasing leaching efficiency for certain elements like Mn, Cu, Co, Ni, Zn, and Pb. Overall, microwave heating offers a potentially effective method for extracting trace elements from red mud.

Summary: Long-term organic fertilization significantly increased total Cu, Zn, and Cd concentrations in Chinese croplands. Organic fertilizer type and application rate were key factors in determining PTTE concentrations, with organic fertilizers containing less than 1 mg/kg Cd recommended for safe application. Soil type under long-term inorganic fertilization played a main role in determining available PTTE variation, leading to higher pollution risk in certain soils.

Summary: Excessive use of phosphorus-based fertilizers may lead to environmental damage and accumulation of heavy metals in soil and crops. The study found that the application of phosphatic fertilizers increased the concentration of chromium, lead, and copper in soil and wheat grains. The concentration of lead, nickel, and zinc in wheat grains exceeded the recommended limits. The trend of heavy metal translocation factor and daily intake showed variations, with lead posing higher health risks for adults and children.

Summary: Pollution poses a major threat to marine life, and trace elements are highly toxic pollutants in this environment. Zinc, an essential trace element for biota, becomes toxic at high concentrations. Sea turtles, with their longevity and widespread distribution, are good bioindicators for trace element pollution, accumulating these elements in their tissues over the years. This study compared the bioaccumulation of zinc in the liver, kidney, and muscles of 35 green sea turtles from Brazil, Hawaii, the USA (Texas), Japan, and Australia. The results showed that zinc was present in all specimens, with the highest concentrations in the liver and kidneys. The findings of equal zinc values in the liver suggest a pantropical distribution pattern for this metal, possibly due to its essential nature and bioavailability in marine environments. This study highlights the importance of understanding the distribution patterns of trace elements in marine biota for conservation purposes and suggests that green turtles can serve as useful sentinel species.

Summary: Recycling phosphorus from wastewater to crop-soil systems using microalgae and HTC technology is a sustainable strategy to improve plant PUE. Charring microalgae biomass into hydrochars promotes the transformation of soluble and exchangeable P into Fe/Al-bound P, enhancing soil P availability and improving PUE. Application of hydrochars from microalgae-derived biomass resulted in slow and persistent release of P, leading to improved wheat PUE and yield compared to chemical fertilizer.

Summary: Leaf ionome is influenced by plant phylogenetic evolution and responses to environmental stress, as well as by the nature of local edaphic sites. Different plant species show specific preferences in ionomic accumulation, influenced by both phylogenetic factors and environmental stresses. Additionally, ionomic differences among plant families mainly stem from non-essential elements.

Summary: Hydrothermal carbonization (HTC) can increase rice yield and improve nitrogen use efficiency, but the NH3 volatilization is influenced by surface water NH4+-N concentration and pH, soil TOC, and NH4+-N oxidation functional genes. Therefore, there is still a long way to go before HTC can be fully applied for nitrogen fertilizer reduction and waste recycling.

Summary: Ionomic variations are influenced by genetic and environmental factors, as well as varietal effects and subspecies effects. Variations in root-to-shoot ionomic transport mechanisms are the main causes of ionomic differences among subspecies. Japonica subspecies exhibit the strongest elemental correlations and covariation effects, which contribute to the breeding of biofortified rice. Geographical and historical distribution significantly define ionomic profiles.

Summary: After the Fukushima Dai-ichi Nuclear Power Plant accident, the release of radioactive cesium was more significant than radioactive strontium in the surrounding environment. Most countermeasures focused on reducing cesium uptake by plants. However, preventing the transfer of strontium from soil to plants should also be prioritized to avoid similar consequences as seen after the Chernobyl and Mayak accidents.

Summary: Oxygen nanobubble-loaded biochars have been found effective in reducing copper toxicity in paddy soils and improving crop productivity. This amendment improves the redox potential and dissolved oxygen concentration in the rhizosphere, promotes root iron plaque formation, and inhibits copper influx. It also enhances soil microbial diversity and increases bacterial genes abundance involved in copper complexation and export. The sequestered copper in root iron plaque and soil bacteria prevents its accumulation in edible parts of the plants.

Summary: Reducing ammonia (NH3) volatilization from intensive cropping systems is essential for preventing pollution and ensuring sustainable agriculture. This study calibrated and evaluated the DNDC model using a two-year field experiment to simulate NH3 volatilization and crop production in a rice-wheat rotation system under different fertilizer treatments. The results showed that the calibrated DNDC model effectively simulated NH3 volatilization and grain yields for both crops. The sensitivity analysis revealed that N application rate greatly influenced NH3 volatilization, and the mixed application of inorganic and organic fertilizer significantly mitigated NH3 volatilization and improved crop yields.
