TL;DR: This work is designed to provide a comprehensive overview that summarizes current knowledge and research findings on environmental occurrences, fate and transport, and impacts of MPs and also summarizes both the experimental and modeling data of the environmental fate and Transport of MPs.

TL;DR: Results suggested that the CN2% treatment performed excellently in terms of reducing Ni concentrations in leaves and roots of lettuce plants along bioavailable Ni in the soil after plant harvest, whereas, application of BR at 2% could remarkably develop aforementioned parameters in lettuce plants.

TL;DR: Different methods to remove fluoride from water such as reverse osmosis, electrocoagulation, nanofiltration, adsorption, ion-exchange and precipitation/coagulating were introduced in this study.

TL;DR: To investigate contamination level, origins and spatial distribution characteristics of heavy metals in agricultural soils of Gaogang Town, a typical industrial transfer-undertaking region of the Pearl River Delta, China, a total of 162 surface soil samples were collected in August 2016 and the results indicated that these elements had cumulative trends in soil.

TL;DR: The nanofibers membranes fabricated by poly(vinyl alcohol)/chitosan (PVA/Chi) using an electro-spun technique for selective and high adsorption of lead and cadmium ions based on the solution acidity are considered to be effective and promising materials for Pb( II) and Cd(II) ions from wastewaters with high efficiency.

TL;DR: An integrated approach of AgNP synthetic methods using bacteria, fungi, and plants, AgNP cytotoxic and genotoxic effects as well as their potential therapeutic applications are presented.

TL;DR: The results showed that soil physicochemical properties and heavy metals significantly affected the microbial community, and Proteobacteria and Firmicutes were highly resistant to heavy metals.

TL;DR: The usefulness of biosurfactants in the removal of environmental contaminants and, consequently, expanding environmental safety and drive towards greener technology is confers.

TL;DR: The sorption of phenanthrene and nitrobenzene to micron-, submicron- and nano- sized polystyrene microplastics is investigated to improve the understanding of the fate and risks of microplastic associated with the two typical organic contaminants in the micrometer to nanometer scale.

TL;DR: The current work collected and discussed the mechanisms of PM2.5-induced CNS damage and PM2-induced neurodegenerative diseases are discussed.

TL;DR: The results indicate that the co-application of PGPR and rhizobium can have a positive effect on the biochemical responses of alfalfa-soil systems in soil contaminated by heavy metals and can provide an efficient strategy for the phytomanagement of metal-contaminated land.

TL;DR: PFAS alternatives exhibited comparable or even more serious potential toxicity than legacy PFASs, indicating that these fluorinated alternatives are also harmful to the environment, therefore, these alternatives require additional toxicological studies to confirm whether they can be used for a long time.

TL;DR: The risk assessment showed that each watershed was at potential medium ecological risk based on their mean concentration (RQTotal > 1), and pesticides were the main compounds arising risks.

TL;DR: It was found that pyrolysis process promoted changes in the chemical speciation and biochar matrix characteristics, leading to reduce bio-available fractions of heavy metals in the biochars.

TL;DR: Some microorganisms had strong tolerance to heavy metal contamination and had certain heavy metals digestion ability, which can create an appropriate soil environment for the growth of food crops.

TL;DR: The effects on the aryl hydrocarbon receptor (AHR) pathway, disruption of the oogenesis process, and neurotoxicity could be caused by acute exposure of adult zebrafish to microplastics.

TL;DR: This study aims to integrate wastewater and landfill leachate treatment with the production of microalgal biomass, considering not only its valorization in terms of lipid and carbohydrate content but also the effect of nutrient limitation on biomass formation.

TL;DR: The study results suggest that the occurrence and risks of emerging endocrine-disrupting compounds in coastal waters are deserving of further studies, especially in densely populated regions of the world.

TL;DR: The use of sewage sludge-derived biochar or the combination of sewagesludge with wood biochar in mining areas are potential alternatives for reusing and aggregating value to these locally available wastes, offering an opportunity to solve both soil remediation and waste disposal problems at once.

TL;DR: It is suggested that Se modified root morphology and regulated nutrient elements uptake by root, which might play a combined role in reducing Cr uptake byRoot, consequently alleviating Cr stress and maintaining plant growth.

TL;DR: A review of the literature reveals that BPS has widespread presence in environmental media, such as indoor dust, surface water, sediments, and sewage sludge, and it has been detected in plants, paper products, some food items, and even in the human body.

TL;DR: It is demonstrated that exposure to microplastics significantly decreases larvae swimming competence, which may have significant impacts on its population fitness in the aquatic environment and further ecological consequences.

TL;DR: High Cd accumulation (greater Cd tolerance) in Bainong 160 is associated with higher photosynthetic parameters, higher activities of antioxidant enzyme and higher concentration of hormones than Pingan 8.

TL;DR: PM2.5 may induce mitophagy via activating PINK1/Parking signal pathway by increasing ROS, thereby activating HSCs and causing liver fibrosis.

TL;DR: A novel cyclodextrin polymer (β-CDP) has been successfully prepared by nucleophilic substitution of β-cyclodesxtrin with tetrafluoroterephthalonitrile (TFP) and demonstrated remarkable advantages of β -CDP material relevant to organic micro-pollutants removal in wastewater treatment.

TL;DR: The results suggested that microplastics might be an important reservoir of ARGs in RAS farms, and microbial communities of microplastic and water showed significant difference at both phylum and genus levels.
