Abstract Adsorption technology is a hot topic in the field of dye removal, and higher adsorption capacity is one of the eternal themes. Ionic dyes account for more than 90% of the literature on dyes adsorption in recent decade. In this article, various physical and chemical mechanisms of dye adsorption are combed in detail, and electrostatic interaction is the major mechanism of ionic dyes adsorption. The key to improving the adsorption capacity is to increase the electrostatic interaction force/surface charge of adsorbents. Moreover, different modification methods to improve the adsorption of ionic dyes by changing the charge properties of adsorbents were reviewed, including grafting functional groups, composite, and adsorbent structural modulation. The practical prospects of each modification method/substance were highlighted and discussed from the perspectives of performance, preparation processes, cost, and toxicity. This review mainly includes (1) the classification and adsorption mechanisms of dyes; (2) types, performance and application prospects of grafted ligands and substances applied for compositing; (3) the performance and limitations of the structural regulation methods; (4) research progresses of amphoteric adsorbents; (5) the prospect of adsorbents development and industrial-scale application. This review attempts to provide a detailed reference for the modification of adsorbents via electrostatic interaction regulation. Graphical Abstract

Abstract The agricultural sector is increasingly dependent upon the use of plastic products to enhance productivity. In addition to many incidental inputs, plastic fragments are progressively accumulating in soil following the degradation of plastic products. Microplastics (MPs, <5 mm) and nanoplastics (NPs, <1 µm) in agricultural soils have caused substantial concerns recently. The insidious interactions between plants, soil, and MPs/NPs in the agricultural environment could affect soil health, crop productivity, and threaten food safety and human health. Importantly, finer NPs can be taken up by plants, induce oxidative stress and negatively affect plant growth. Even though interactions of MPs/NPs with plants in the plant-soil nexus have been reported, a comprehensive review of the state of knowledge is lacking, which hinders continued progress in this emerging field. This review aims to fill the gap by extensively summarizing MPs/NPs sources in agriculture, techniques to investigate, impact on soil properties and accumulation in the plants. The synergistic effect of organic and inorganic co-contaminants and MPs/NPs are highlighted due to the widespread presence of these chemicals in agricultural soils. This review also presented possible mechanisms of MPs/NPs phytotoxicity. Although new information is emerging there is a paucity of data on the fate and impact of MPs/NPs in the plant-soil nexus. More efforts are needed to elucidate the fate and impact of MPs/NPs in agricultural soils to gain a deeper understanding of their health and safety implications. Graphical abstract

Abstract Microplastics are widespread contaminants leading to environmental exposure. While studies on the prevalence in human tissues have multiplied, little is known about their pharmacokinetics. Mechanisms of absorption, distribution, metabolism, and excretion (ADME) must be addressed before effects on human health (i.e. pharmacodynamics) can be understood. Therefore, the objective of this review was to provide an integrated assessment on the fate of microplastics in the human body by gathering information from multiple fields of research (e.g. implants and microspheres). Absorption of microplastics mainly occurs through transcytosis in enterocytes, while larger particles may be internalized through gaps (e.g. persorption) or by uptake by phagocytes. Only microplastics <5 µm may reach the alveolar region, while large particles found in the lungs usually result from entrapment of circulating particles in the narrow pulmonary capillary network. Overall, absorption rates of microplastics are expected to be low. Microplastics are then distributed by the circulatory system, accumulating in the respiratory system, digestive system, liver, spleen, and brain. Metabolism may lead to the biodegradation of microplastics, mainly through enzymes and reactive oxygen species of macrophages, exposure to physiologic fluids, and microbiologic activity in the gut lumen. Finally, most microplastics will be removed by the liver or spleen and excreted in the feces. While this work provides an initial attempt at constructing a pharmacokinetics model for microplastics, further research is required. Ideally, future works should be conducted using histopathology techniques to obtain the precise location in the tissues and radiolabelled particles to allow tracking through time. Graphical Abstract

Abstract Organochlorine pesticides (OCPs) have been widely used around the world due to their high-efficiency and broad-spectrum insecticidal effects. However, they pose a severe threat to ecosystems and human health due to their easy bioaccumulation and high toxicity. Periphyton is ubiquitous in the submerged substrates surface. It plays a crucial role in carbon, nutrients elements cycling and contaminants transformation in environment. Periphyton can remove OCPs through bioadsorption, bioaccumulation and biodegradation, which alters the fate of OCPs in environment. This review presents a comprehensive summary of OCPs occurrence, global cycle, potential harm in environment, and their removal by periphyton. The OCPs residual have been detected frequently in different environmental medias such as water, soil, atmosphere, sediment, and organisms. Their harm is depending on their physicochemical properties and the exposure route. The main compositions and functions of periphyton have been summarized. Moreover, the artificial cultivation methods of periphyton in laboratory and in-situ field are compared. In addition, the mechanisms of periphyton-mediated OCPs removal and the main factors impacting OCPs removal are also discussed. Periphyton could self-regulate its biological communities to adapt to the OCPs and environment, and then regenerate new species to degrade OCPs. Finally, the prospect of OCPs removal by periphyton and future studies are also proposed. This review provides a systematic introduction on current knowledge of OCPs occurrence, cycle, potential harm in environment, and their removal by periphyton. Graphical Abstract

Abstract The oceans, serving as some of the most extensive reservoirs of mercury (Hg) on Earth, play an essential role in the global Hg biogeochemical circulation, as a sink for atmospheric deposits and surface runoff while simultaneously emitting Hg to the atmosphere. Clarifying the mechanisms during cycling of Hg in marine ecosystems is a crucial segment in elucidating global Hg behavior and assessing its risks to wildlife and humans. The stable Hg isotope technique has emerged as a powerful tool for identifying potential sources and certain processes of Hg. Herein, the research advances in marine Hg biogeochemical cycling were reviewed from an isotopic tracing perspective, including sources of marine Hg, isotopic fingerprints across various marine media, and applications of Hg isotopes in pathways, transport, and transformation mechanisms associated with marine environments. The knowledge gaps and challenges were further discussed in the development of ultratrace level and species-specific isotopic analytical methods, the isotope fractionation mechanisms in reactions and processes, and the integration of multiple approaches and cross disciplines. These future studies would advance our understanding of Hg behavior in oceanic environments, its authentic function, and interactions with other ecosystems in the global Hg cycle, and evaluate its response to environmental changes.

Abstract Biochar-derived dissolved organic matter (BDOM) plays key roles in soil ecosystem by affecting soil physicochemical and biological properties and supplying nutrients to soil microbes. It can either enhance or suppress the growth of certain soil microorganisms, depending on its composition and content of labile organic compounds. This review aims to discuss and summarize the role of BDOM in modifying soil microbial functioning, microbial community structure, and enzymatic activity. We mainly focus on the role of BDOM as a function of its concentration, type of feedstock biomass, and pyrolysis temperature (PT). Results show that saw dust- and manure-based biochars produce higher BDOM concentrations than straw-, bone-, and sludge-based biochars. The types of feedstock biomass and its PT determine BDOM characteristics and its interaction with soil microbial communities. Plant-derived biochar with pyrolysis temperature ≤300 °C often results in a more aliphatic BDOM than that with pyrolysis temperature ≥500 °C, which yields a more aromatic BDOM. BDOM of plant biochar contains higher specific ultraviolet absorbance (SUVA) and humification index (HIX) than that of manure biochar. The SUVA and HIX of BDOM positively correlate (R 2=0.68–0.96) with the content of total fatty acid methyl esters, but negatively correlate with the abundances of actinomycetes, arbuscular mycorrhizae, and fungal communities. However, the environmental fate of BDOM in biochar amended soil requires long-term experiment, both in laboratory and field scales, to provide a full understating of BDOM interaction with soil organic matter and microorganisms and help to tailor a safe utilization of biochar in agroecosystems.

Abstract The oxidation of sulfur dioxide (SO2) to sulfate in the atmosphere is an important concern in regional air quality, global climate change, and human health. While gas-phase and liquid-phase oxidation of SO2 are widely regarded as important sources of sulfate, the contribution of the heterogeneous oxidation process on particle surfaces is controversial. Recently, this heterogeneous chemistry has been considered to be an important mechanism that is missing in current models to explain sulfate concentrations observed in haze episodes in East Asia. Therefore, the heterogeneous oxidation of SO2 on particles under the conditions of complex air pollution needs to be reassessed. This review summarizes the fundamental understanding of the heterogeneous reactions of SO2 on solid particles such as mineral dust, black carbon, sea salts, organic aerosol, and so on. The factors affecting the mechanism and kinetics of the heterogeneous reactions of SO2, including coexisting components (O3, NO2, H2O2, NH3, and VOCs), reactive sites, surface properties, relative humidity, and illumination, are reviewed. Reactive oxygen species involved in the heterogeneous oxidation of SO2 on particles are discussed. To our knowledge, while previous reviews have appeared on the oxidation of SO2 in the aqueous-phase, this is the first review on the atmospheric heterogeneous reactions of SO2 on the surface of solid particles, which can be of help in understanding the sulfur cycle in the atmosphere and its environmental impacts. A number of recommendations for future research are also presented.

Abstract Converting biomass to produce renewable chemicals is one of the significant ways to realize the development of green chemistry and sustainable chemical industry. As the main component of lignocellulosic biomass, lignin is the most abundant natural polyphenol. Its unique phenolic properties and high carbon content make it potentially exploited. Biomass lignin depolymerization can be divided into thermochemical, chemical catalysis, electrocatalysis, and biological depolymerization methods. In this review, the catalytic reaction systems involved in different methods of lignin depolymerization were extensively described from various aspects, and the degradation products and reaction mechanisms were discussed and analyzed. The effects of novel green-deep eutectic solvents on biomass lignin depolymerization were reviewed in particular. Each method of biomass lignin depolymerization has its own advantages and disadvantages. The different sources of biomass lignin should be selected objectively according to its compositional structure, so as to achieve efficient biomass lignin depolymerization. In addition, the challenges and future development prospects of biomass lignin depolymerization were also discussed.

Abstract With the continuous release into environments, emerging contaminants (ECs) have attracted widespread attention for the potential risks, and numerous studies have been conducted on their identification, environmental behavior bioeffects, and removal. Owing to the superiority of dealing with high-dimensional and unstructured data, a new data-driven approach, machine learning (ML), has been gradually applied in the research of ECs. This review described the fundamental principle, algorithms, and workflow of ML, and summarized advances of ML applications for typical ECs (per- and polyfluoroalkyl substances, nanoparticles, antibiotic resistance genes, endocrine-disrupting chemicals, microplastics, antibiotics, and pharmaceutical and personal care products). ML methods showed practicability, reliability, and effectiveness in predicting or analyzing the occurrence, distribution, bioeffects, and removal of ECs, and various algorithms and derived models were developed and optimized to obtain better performance. Moreover, the size and homogeneity of the data set strongly influence the application of ML, and choosing the appropriate ML models with different characteristics is crucial for addressing specific problems related to the data sets. Future efforts should focus on improving the quality of data set and adopting more advanced algorithms, developing the potential of quantitative structure-activity relationship, and promoting the applicability domains and interpretability of models. In addition, the development of codeless ML tools will benefit the accessibility of ML models. Graphical abstract

Abstract Soil pollution from potentially toxic elements (PTEs) is a serious environmental issue worldwide that affects agricultural safety and human health. Arbuscular mycorrhizal fungi (AMF), as ecosystem engineers, can alleviate PTE toxicity in crop plants. However, the comprehensive effects of AMF on crop performance in PTE-contaminated soils have not yet been recognized globally. Here, a meta-analysis of 153 studies with 3213 individual observations was conducted to evaluate the effects of AMF on the growth and PTE accumulation of five staple crops (wheat, rice, maize, soybean, and sorghum) in contaminated soils. Our results demonstrated that AMF had strong positive effects on the shoot and root biomass. This is because AMF can effectively alleviate oxidative damage induced by PTEs by stimulating photosynthesis, promoting nutrition, and activating non-enzymatic and enzymatic defense systems in crop plants. AMF also decreased shoot PTE accumulation by 23.6% and increased root PTE accumulation by 0.8%, demonstrating that AMF effectively inhibited the PTE transfer and uptake by crop shoot. Meanwhile, AMF-mediated effects on shoot PTE accumulation were weaker in soils with pH > 7.5. Overall, this global survey has essential implications on the ability of AMF to enhance crop performance in PTE-contaminated soils and provides insights into the guidelines for safe agricultural production worldwide.
