TL;DR: The results depicted that NPs positively affected the photosynthesis of wheat as compared to the control, suggesting that the NPs play a major role in the increase in biomass, nutrients and decrease in Cd toxicity in wheat.

TL;DR: Results of ingestion and dermal pathways for adults and children in the current analyzed review showed that As is the major contaminant, and remediation techniques such as the introduction of aquatic phytoremediation plant species and adsorbents should be included in land management plans in order to reduce human risks.

TL;DR: In this review, recent advances in AMD prevention techniques like oxygen barriers, utilization of bactericides, co-disposal and blending, and passivation of sulfide minerals are discussed and recycling of mine tailings as construction and geopolymer materials to reduce the amounts of wastes for disposal are introduced.

TL;DR: Microplastics caused multiple toxic effects in fish intestine, including mucosal damage, and increased permeability, inflammation and metabolism disruption, and it is suggested that shape-depended effects should not be ignored in the health risk assessment of microplastics.

TL;DR: This is the first detailed study on the effect of nano- and microplastics on a vascular, terrestrial plant, and the results indicate short-term and transient adverse effects.

TL;DR: Microplastics act as an emerging hotspot for metal driven co-selection of multidrug resistant human pathogens and pose serious threat to humans which do recreational activities in marine environment and ingest marine derived foods.

TL;DR: An overview of water pollution by these pollutants, as well as a review of the recent literature about the use of low-cost adsorbents for the removal of the main pharmaceuticals found in surface water, focusing on municipal and agroindustrial wastes as precursors are presented.

TL;DR: The present review of the scientific literature from 1991 to 2018 on heavy metals in soils in India shows that Zn and Pb exceeded their limits for Indian natural soil guidelines, as well as Canada, Sweden, Sweden and Poland.

TL;DR: This review is the first to comprehensively summarize the progress in design and antimicrobial performance of g-C3N4-based photocatalysts for water disinfection and microbial control, involving not only bacteria but also viruses and microalgae.

TL;DR: This study reveals the contamination and characteristics of microplastics in the Pearl River, and provides important data for further research on microplastic pollution in freshwater ecosystems.

TL;DR: By cyclic degradation experiments, the performance of MnFe2O4/bio-char composite is stable and almost unchanged, and the leaching metal ions of both Fe and Mn are neglectful (both below 0.2 mg L-1).

TL;DR: A data-driven model, called as long short-term memory - fully connected (LSTM-FC) neural network, to predict PM2.5 contamination of a specific air quality monitoring station over 48 h using historical air quality data, meteorological data, weather forecast data, and the day of the week is proposed.

TL;DR: A critical review of the related literature is provided to establish the "structure-property-application" relationships for the development of innovative carbon-supported nanocomposites and to promote future research on the integrated adsorptive and photocatalytic removal of VOCs.

TL;DR: The results show that polystyrene microplastic could cause alterations in the microbiome at the phylum and genus levels in larval zebrafish, including changes in abundance and diversity of the microbiome, and indicated that the potential effects of environmental microplastics on aquatic organisms should not be ignored.

TL;DR: Basic information on the toxicity of 0.1 μm and 5 μm polystyrene microplastics in human intestine cells is provided, which are useful for assessing the risk of PS-MPs in humans.

TL;DR: The main objective of this article is to provide the first critical review of the peer-reviewed studies on the analytical methods, occurrence, mobility, and treatment for ultra-short-chain PFAS (C = 2-3) and short-chainPFAS ( 4-7) and identify the future research needs.

TL;DR: This work provides theoretical guidance for subsequent research in the field of adsorption and photocatalytic removal of antibiotics from aqueous solution, especially on influence factors and mechanisms aspects.

TL;DR: Results evidently showed that MT enhanced tolerance of wheat seedlings to Cd toxicity by triggering the endogenous NO, and both MT and NO together enhanced Cd tolerance in wheat.

TL;DR: Investigation of the distribution of microplastic around the slum area of Ciwalengke River in Majalaya, Indonesia found that more fiber shape might be derived from the direct clothing of residents in the river and fabric washing process in the textile industries.

TL;DR: A series of TiO2/biochar composite catalysts prepared by the hydrolysis method for the degradation of methyl orange, where biochar was obtained from the pyrolysis of waste walnut shells showed that the catalysts noted as CT0.2/1 exhibited the highest catalytic activity and CT1/1 possessed the lowest activity due to the shelter of light by the excess biochar.

TL;DR: The results suggest that nanoplastics can be ingested by the freshwater cladoceran D. pulex and affect its growth and reproduction as well as induce stress defense.

TL;DR: In this work, biochar from anaerobically digested sludge was synthesized and characterized to explore the competitive behavior of widely co-existed Pb(II) and Cd(II), and it was clearly demonstrated the competitive adsorption between two metals occurred as well as the preference of biochar for Pb (II) compared to Cd (II).

TL;DR: The results showed that the sorption of SMX onto microplastics reached equilibrium within 16 h, and the external mass transfer was the slowest sorption step.

TL;DR: A state-of-the-arts review of the most important aspects of the electrochemical production of hydrogen peroxide (H2O2) by 2-electron oxygen reduction reaction (ORR) and an outlook on future research challenges are proposed.
