Summary: The accumulation of toxic and persistent lindane in soil landfills poses a risk of leaching and contamination of surrounding rivers. A simple and cost-effective composite consisting of magnesium oxide (MgO) and activated carbon (AC) has been proposed to remove lindane in soil and water. The use of MgO provides a basic pH and allows for the total adsorption of heavy metals in contaminated soils, while AC provides sites for lindane adsorption and a reductive atmosphere. This composite has shown highly efficient remediation capabilities, allowing for the elimination of lindane and immobilization of heavy metals.

Summary: This study evaluated the growth of hybrid Miscanthus in different contaminated soils and found that the plant performed well in metal-contaminated soil but poorly in petroleum-contaminated soil. The microbial communities responded differently to the different types of contamination, with no microbial stress in agricultural soil, reduced stress in post-military soil, and increased stress in petroleum-contaminated soil over time.

Summary: A new index is proposed to determine the affinity of heavy metals to carrier phases, taking into consideration the sum of metals in the phase as a share of the bulk content of all metals in the soil. The study reveals discrepancies in the affinity series of metals for phases based on different indices, and suggests that the organophilic properties of metals are affected by the mineral composition and organic matter specificity in contaminated soils.

Summary: Research on the interaction between plants and potentially toxic elements has mainly focused on angiosperms, while lower plant clades have been somewhat overlooked. Recent studies have shown the potential of bryophytes, pteridophytes, and gymnosperms in environmental sciences, as indicators of habitat health and elemental pollution, as well as tools for soil and water reclamation.

Summary: Urban forest soils in New England were evaluated for trace elements using portable X-ray fluorescence (pXRF) and traditional digestion-inductively coupled plasma analyses. Results showed extensive Pb accumulation in urban forest soils, while limited samples exceeded regulatory limits for As and Zn. Pb and Zn concentrations were higher in urban forest soils near multi-family residences compared to recreational and open lots. pXRF measurements were considered accurate for Cu, Pb, and Zn, but caution is needed when using pXRF for Cd and Cr. Additional processing of soil samples did not significantly improve accuracy and precision.

Summary: Planting strategies can effectively reduce diffuse pollution from agricultural catchments reaching water bodies. Manuka has potential to inhibit urease activity and nitrification, reducing on-farm nitrate leaching. However, field conditions make quantifying such phenomenon more complex.

Summary: The elemental concentrations in soils may influence the antimicrobial properties of manuka honey, with certain elements showing negative correlations with MGO levels. There were no clear correlations between honey, plants, and soils for individual elements, except for potassium. Additionally, soil fertility may play a role in determining manuka honey quality due to its negative correlation with MGO and DHA concentrations.

Summary: Novel research has shown that pathogen phytoremediation plants can reduce the transport of human pathogens to water sources by enhancing die-off of pathogenic organisms in the soil. Several New Zealand native plants have demonstrated antimicrobial activity, with Leptospermum scoparium and Metrosideros robusta showing the most significant reduction of Escherichia coli numbers in soil compared to other plant species.

Summary: The application of biosolids in coastal dune forests did increase the levels of carbon and nitrogen in the soil, but did not significantly affect the mineral protection and chemical stability of soil organic matter (SOM). This suggests that while biosolids can lead to immediate carbon accumulation, its potential for long-term soil carbon sequestration may be limited due to weak mineral protection and altered plant-microbial interactions.

Summary: Over 30 million tonnes of biosolids are produced annually, with most being disposed of in landfills or waterbodies. However, bioconversion using Black Soldier Fly larvae can transform these biosolids into high-value biomass while reducing waste volume. The study found that blending biosolids with organic waste improved the performance of the larvae, and heavy metals were largely partitioned into residues rather than accumulating in the larvae.

Summary: Plants have the ability to modify the nitrogen cycle in soil through various mechanisms, such as N uptake, root exudation, and nitrification inhibition. This study aimed to investigate the impact of New Zealand native plant species on the abundance of nitrifying and denitrifying microorganisms in the soil. The results showed that plant species had a significant effect on the abundance of certain functional genes and the chemical properties of the soil.

Summary: Black soldier fly (BSF)-based bioconversion can reduce organic waste and produce valuable BSF larvae and frass. The frass can be used as fertilizer, but the feedstock type determines its application. Frass from food waste is the most suitable, while frass from bioconverted biosolids needs to be used at similar rates as unconverted biosolids to avoid phytotoxicity.

Summary: Research on the potential of native species to manage nutrients and contaminants in treated municipal wastewater is limited. In a 10-hectare field site, the distribution of nutrients and trace elements in the soil-plant system was investigated, comparing native Myrtaceae species with pasture. Results showed that plant growth was not influenced by wastewater irrigation rates. Myrtaceae species had higher foliar trace element concentrations, but pasture accumulated more nitrogen and phosphorus.

Summary: The widespread use of emerging contaminants may worsen antibiotic resistance, as these contaminants have been found to alter bacterial responses to antibiotics and increase the spread of antimicrobial resistance genes. The study investigated the effects of nine emerging contaminants on antibiotic resistance and gene transfer, and found that the observed effects varied at different antibiotic concentrations.

Summary: Antimicrobial resistance (AMR) poses a global threat to human and ecological health, with emerging organic contaminants (EOCs) playing a significant role in its expansion. EOCs, widely used in various industries, can accumulate in the environment via waste streams and interact with microbial communities, potentially leading to the emergence and spread of AMR. Addressing this important threat requires collaboration across all sectors and the implementation of robust strategies and policies.
