Summary: This paper comprehensively reviews the status of greenhouse gas (GHG) production and emission in wastewater treatment. It reveals that nitrous oxide (N2O) emission contributes significantly to the total GHG emissions, and emphasizes the importance of dissolved N2O and methane (CH4) in effluent for further GHG mitigation. Alternative integration systems, such as coupling denitrifying anaerobic methane oxidation with anammox process, are discussed as promising approaches for GHG mitigation. Moreover, strategies to manage N2O and CH4 as energy sources are demonstrated for offsetting carbon footprint in wastewater treatment and achieving net-zero GHG emission.

Summary: Nitrous oxide (N2O) is an important greenhouse gas with increasing atmospheric concentrations due to industrialization and nitrogen fertilizer use. It is found that the contribution of freshwater systems to N2O emissions is uncertain, and the regional differences in N2O concentrations in rivers are influenced by local hydrology. The study in the Haut-Loir watershed in France showed significant variations in dissolved N2O concentrations between eastern and western rivers, suggesting that spatial variability of riverine N2O depends on local hydrology. The research also highlights the need for further studies to understand the seasonal variability of N2O emissions.

Summary: Increasing global deoxygenation has led to oxygen-limited biotopes and intensified nitrous oxide greenhouse effect. Previous understanding considered low oxygen as the key factor affecting N2O emissions from incomplete denitrification, but this study demonstrates for the first time that sulfur cycling can enhance complete denitrification even in oxygenated environments. This research highlights the potential to reduce N2O-driven greenhouse warming and fills a gap in our knowledge of the nitrogen cycle.

Summary: In recent years, the release of metal and metallic oxide engineered nanoparticles (ENPs) into the environment has led to an increased accumulation in agricultural soils, posing significant risks to the ecosystem and soil health. This study examines the impact of ENPs on the physical and chemical properties of soils. The results show that the presence of ENPs can alter soil properties such as hydraulic conductivity, porosity, pH, CEC, EC, Eh, and SOM content, as well as influencing nutrient availability in the soil solution through complexation or precipitation with metal cations released from ENPs.

Summary: In the past decade, the use of nanoscale zero-valent iron (nZVI) as an adsorbent has gained attention due to its low cost, non-toxicity, high porosity, and BET-specific surface area. Immobilizing nZVI particles onto inorganic and organic substrates has decreased their agglomeration and enhanced their adsorption capacity for pollutants. However, there is a lack of comprehensive review studies on phosphate removal from aquatic systems. This study evaluates different types of nZVI and nanocomposites, factors affecting phosphate adsorption, and the mechanisms involved in phosphate removal.

Summary: This study aims to unravel the co-adsorption mechanisms of Cd(II) and As(III) by a Pennisetum sp. straw biochar (BC) modified with Fe-Mn oxide (FMBC). The maximum adsorption capacity of Cd(II) and As(III) by FMBC was 141.1 and 31.8 mg/g, respectively, which was 2.71 and 3.89 times higher than that of BC. In the dual-adsorbate system, Cd(II) increased the adsorption of As(III) on FMBC by 5.1-123.9%, while As(III) reduced the adsorption of Cd(II) by 0.7-24.8%, indicating respective synergism and competition effect.

Summary: Sustainable management of organic biowaste and arable soil contamination by toxic elements is a concern. A pot trial was conducted to remediate As/Pb co-contaminated soil using chitin, crawfish shell biochar, crawfish shell powder, and CT-CSB composite. Results showed that the addition of amendments decreased Pb bioavailability, with CT-CSB treatment being the most effective. CSP and CSB increased soil available As concentration, while CT and CT-CSB treatments reduced it. CT addition enhanced soil enzyme activities, while CSB-containing treatments suppressed most enzymes. Bacterial abundance and composition in soil were altered by the amendments, and soil chemical properties were strong predictors of As/Pb availability. CT-CSB can potentially immobilize As and Pb and restore soil ecological functions.

Summary: Earthworms are being studied for their potential in bioremediation due to their impact on pollutant fate. Different earthworm species have varying sensitivities and capacities to break down contaminants, and Lumbricus terrestris is the most suitable species for bioremediation of OP-contaminated soil due to its higher levels of detoxification enzymes and oxidative homeostasis mechanisms compared to Eisenia fetida andAporrectodea caliginosa. These findings suggest L. terrestris as a better candidate for soil bioremediation than epigeic earthworms.

Summary: This study found that plant available silicon (ASi) content in coastal wetlands in China is mainly influenced by soil pH, particle size, and nutrients. Vegetation composition and plant-derived lignin have a minor effect on ASi patterns. Mean annual temperature and precipitation indirectly regulate ASi content by affecting soil geochemistry and nutrient distribution. Therefore, ASi distribution in China's coastal wetlands is mainly controlled by primary pedogenesis and specific weathering processes.

Summary: This study investigated the adsorption capacity of different biomass feedstocks for Pb(II) and the effect of magnetic modification on the adsorption capacity. Results showed that rice straw biochar had the highest adsorption capacity due to its rich mineral content and oxygen-containing functional groups. Magnetic modification improved the adsorption capacity of biochar by changing its surface properties. The study suggests that biochar could be a feasible and effective strategy for removing Pb(II) from wastewater.

Summary: The pollution of microplastics (MPs) is a global concern as they are now a significant part of the food chain. This article reviews the current scientific literature on MPs and their impact on various life forms. Negative effects of MPs on humans are primarily attributed to oxidative stress and immune disruption. MPs not only affect the soil's chemical and physical properties, leading to reduced soil health and productivity, but also harm soil microorganisms. MP-induced plant growth reduction occurs through three mechanisms: reduced root and shoot growth, decreased photosynthesis accompanied by increased reactive oxygen species production, and compromised nutrient uptake due to altered root growth. In order to mitigate these negative effects, different MP removal methods are discussed, including coagulation, membrane filtration, biochar, and biological degradation in soil and wastewater effluents. The use of ozone as an ultrafiltration technique shows promise for MP removal. The article concludes with recommendations for future research to further understand the negative effects of MPs on various life forms.
