TL;DR: An extensive review of recently published experimental parameters and results for the destruction of organic compounds via activated persulfate is presented, and focus is placed on emerging methodologies and manipulation of traditional activation techniques.

TL;DR: Modification to produce engineered/designer biochar is likely to enhance the sorption capacity of biochar and its potential applications for environmental remediation.

TL;DR: The results revealed that superoxide anion radical and singlet oxygen other than sulfate radical were the primary reactive oxygen species in the Base/PMS system and presented a new pathway for PMS activation and provide useful information for the treatment of wastewater.

TL;DR: Nanoparticle tracking analysis was applied to characterise the formation of nanoplastics during the degradation of a polystyrene (PS) disposable coffee cup lid and the results clearly show an increase in the formationof nanoplastic over time.

TL;DR: This review begins with an introduction to the occurrence of ARB and ARG in different environmental systems such as natural environments and drinking water resources, and the mechanism of the effects of different disinfection processes in water and wastewater.

TL;DR: Based on data obtained from the distribution coefficients, Freundlich and Langmuir adsorption models, and three-dimensional simulation, multimetal advertisersorption behaviors differed from monometal adsorptive behaviors due to competition.

TL;DR: This work provides theoretical guidance for subsequent research in the design and modification of carbon materials for applications in the adsorption removal of antibiotics from aqueous solution.

TL;DR: An overview of geochemistry, toxicity and current removal techniques of arsenic together is laid bare to lay bare the source, behavior of arsenic in various parts of the environment, mechanism of toxicity and various remediation processes.

TL;DR: An overview of the V. faba test system and its efficiency in assessing the cytogenetic and mutagenic agents in different classes of the environmental concerns is offered.

TL;DR: Hydrochars produced from hydrothermal carbonisation at 250 °C have been compared to low and high temperature pyrolysis chars produced at 400-450 °C and 600-650 °C respectively, which suggests that surface area is not the most important factor influencing char ammonium adsorption capacity, while char calcium and magnesium contents may influence phosphate adsorptive capacity.

TL;DR: The adsorbent media which have been used to remove PAHs especially from aqueous solutions including the factor affecting the sorption process reported in 142 literature published between 1934 and 2015 are summarized.

TL;DR: The diverse absorption routes of OPFRs by animals and humans (e.g., inhalation, ingestion, dermal absorption and gill absorption) are reviewed and bioaccumulation and biomagnification potentials in different types of organisms and food webs are summarized.

TL;DR: Whether microplastics can be ingested and whether their presence causes adverse effects after short-term exposure are investigated and underline that, considering high concentrations, microplastic particles can already induce adverse effects in limnic zooplankton.

TL;DR: It is suggested that pyrolysis has potential to create effective, magnetically recoverable adsorbents relevant to environmental application.

TL;DR: The findings of this study reveal the health risks associated with the consumption of heavy metals through the intake of selected fruits and vegetables in adult population of Bangladesh.

TL;DR: Principal component analysis (PCA) revealed that high toxic Cr and Cd in polluted sites may be contributed to anthropogenic sources, it was consistent with the results of dual hierarchical clustering analysis (DHCA), which could give more details about contributing sources.

TL;DR: In this overview, gas flotation technologies, namely dissolved and induced flotation systems, are discussed and enhancement of flotation efficiency by using pre-treatment methods, particularly coagulation-flocculation, is presented.

TL;DR: SEM, XRD, XPS and FT-IR analysis suggested that the multi-adsorption mechanisms including precipitation, ligand exchange and complexation interactions can be evidenced during the phosphate adsorption process by La-composites in La-BC.

TL;DR: The concentration of microplastics in the 125-250 and 250-500 μm size categories significantly increased downstream of WWTP, and secondary microplastic was the dominant type in the quantitative size categories (66-88%).

TL;DR: Overall, distinct pharmaceutical contamination patterns as compared to the Western world can be concluded, which might be a trigger for further research in developing regions.

TL;DR: DDTs have become the significant pesticides and should be considered in aquatic ecosystem risk management and procymidone could disrupt the expression of vitellogenin in the estuarine fish even at environmental concentrations.

TL;DR: Characteristics of MPP suggest that they could be originated primarily from ocean-based sources, and the winds and surface currents during SW monsoon are the driving forces for the transportation and deposition of MPPs on the Goa beaches.

TL;DR: Differences in detection frequencies and observed concentrations due to AFFF release volume are presented along with rigorous data analyses that quantitatively demonstrate phase-dependent differences in the chemical signature as a function of carbon chain-length and in situ PFOS formation.

TL;DR: An environmental perspective on dye toxicity in the background of dye structure and effects of environmental processes has been developed and provides directions for undertaking environmentally sound microbial dye detoxification research.

TL;DR: It is found that Ni4Fe1-LDH can remove more than 92% of MO in 10 min at the 10mg/L MO initial concentration, and 97% of Cr(VI) in 1 h at 4 mg/L Cr2O7(2-) initial concentration.

TL;DR: The high pH and carbonates contents at >500 °C resulted in suitable biochars for soil liming and decreasing soil metals availability, and the high hydrophobity showed over 500 °C disappeared, owing to the loss of labile aliphatic compounds.

TL;DR: This review provides an update on information regarding the production volumes, regulations, as well as the environmental levels, trends, fate and human exposure to chlorinated paraffin mixtures (CPs).

TL;DR: The results indicate that at the beginning of plastic weathering processes chain scission at the polymer surface causes many very small particles to be released into the surrounding solution and those concentrations may vary between plastic types.

TL;DR: PAE concentrations increased with increasing plastic film residues but the soil microbial carbon and nitrogen, enzyme activities and microbial diversity decreased significantly, and soil PAE concentrations were impacted by plastic color and residue volume.

TL;DR: TPC-ACs had similar performances to those of commercial ACs, and might significantly improve the economic balance of the production of pyrolysis oil from waste tyres.
