TL;DR: This review article comprehensively discusses the background, concepts and future trends in phytoremediation of heavy metals.

TL;DR: The most representative pharmaceutical families found in water were described and related water pollution issues were analyzed and the performances of different water treatment systems in the removal of pharmaceuticals were summarized.

TL;DR: The application of biochar for in situ metal immobilization can be feasible provided soil pH is monitored over time, and the time required to reach a hazardous pH can be predicted to be longer after biochar application.

TL;DR: The TiO2 photocatalysis was found to be a promising process for removing TC and its intermediates from aqueous solution by nanosized TiO 2 under UV irradiation.

TL;DR: Irrespective of the dissipation kinetics, the majority of PFOA and PFOS from contaminated soils will be transported to groundwater and surface water bodies and applying lab-based log K(oc) distribution coefficients can result in a serious overestimation of PFC concentrations in water and in turn to an underestimation of the residence time of PFLs in contaminated soils.

TL;DR: It was found that the cytotoxicity of DESs was much higher than their individual components (e.g. glycerine, ChCl) indicating that their toxicological behavior is different.

TL;DR: Results indicated the waste biomass can be converted into value-added biochar as sorbents for removal of heavy metals and the removal ability varies with different biochar feedstock sources where the mineral components originated from the feedstock play an important role in the sorption nature of biochar.

TL;DR: The concentrations found in this study, and their corresponding risk quotient, indicate a significant threat by PPCPs to the health of the Great Lakes, particularly near shore organisms.

TL;DR: It was demonstrated that glyphosate and AMPA are present in soils under agricultural activity, and it was found that in stream samples the presence of glyphosate and aminomethylphosphonic acid is relatively more frequent in suspended particulate matter and sediment than in water.

TL;DR: The sorption of PO4-P, NH4-N and NO3-N to cacao shell and corn cob biochars produced at 300-350°C was quantified and it is speculated that NH4 -N could bind via an electrostatic exchange with other cationic species on the surface of the biochar.

TL;DR: A better understanding of plant-bacteria partnerships could be exploited to enhance the remediation of hydrocarbon contaminated soils in conjunction with sustainable production of non-food crops for biomass and biofuel production.

TL;DR: The results revealed that TiO(2) nanoparticles in anatase crystal structure are toxic in the entire set of tests conducted and demonstrated that exposure duration, aggregation and concentrations are contributing factors in nanoparticles-mediated toxicity.

TL;DR: Increased GR activity coupled with isolated increase in GSH/GSSG ratio does not seem to prevent cells from oxidative damages, as evident from higher MDA level in leaves of nano-CuO stressed seedlings over control, and Enhanced proline accumulation does not give much protection against nano- CuO stress.

TL;DR: The health risk assessment indicated that vegetable consumption would not result in exceeding the safe values of estimate daily intake (EDI) REEs for adults and children, but attention should be paid to monitoring human beings health in such rare earth mining areas due to long-term exposure to high dose REEs from food consumptions.

TL;DR: In this paper, the authors reviewed removal technologies (oxidation, coagulation flocculation, adsorption, ion exchange and membrane processes) with attention for the drawbacks and limitations of these applied technologies.

TL;DR: Multivariate and geostatistical analyses suggested that soil Cr, Ni, and Zn had a lithogenic origin and the elevated Cu concentrations in the study area were associated with industrial and agronomic practices, and the main sources of Pb were industrial fume, coal burning exhausts, and domestic waste.

TL;DR: The results showed that investigated fluoroquinolones degrade very quickly and photodegrades followed pseudo first order kinetics, and the slowest photodegradation rate was observed in river water for all three fluoroquolones.

TL;DR: The results emphasized the need for pretreatment of wastewater and routine monitoring in order to avoid contamination of food crops from the wastewater irrigation system.

TL;DR: Small crystallite size and low band gap were attributed to high activities of Fe-ZnO samples under various concentrations of Fe(3+) ions compared to undoped ZnO, and toxicity removal of 2-chlorophenol at same line of degradation efficiency was indicated.

TL;DR: XRD and FTIR data indicated that the biochar/MgAl-LDHs ultra-fine composites can successfully be obtained by liquid-phase deposition and is an effective sorbent for the removal of phosphate from aqueous solutions.

TL;DR: Potential aerobic biodegradation mechanisms of the widely used polar, low-adsorptive sulfonamide antibiotic sulfamethoxazole (SMX) were investigated in activated sludge at bench scale and enhanced when a readily degradable energy supply was provided which fostered metabolic activity.

TL;DR: Composting with sawdust as a bulking agent was found to emit less total greenhouse gas than the other treatments, and the addition of spent mushroom substrate gave the highest maturity.

TL;DR: Here it is shown that biodegradation of dispersed oil is prompt and extensive when oil is present at the ppm levels expected from a successful application of dispersants, similar to rates extrapolated from the field in the Deepwater Horizon response.

TL;DR: The results suggest that environmental conditions can significantly affect the distribution of antibiotics between water and sediment, and specifically within the PRE area and the coastal zone.

TL;DR: Modeled and experimental results suggest that cVMS may be subject to long-range atmospheric transport, but have low potential to contaminate the Arctic.

TL;DR: In this paper, a review focusing on the overall studies of food waste (FW) composting, not only various parameters significantly affecting the processes and final results, but also a number of simulation approaches that are greatly instrumental in well understanding the process mechanism and/or results prediction.

TL;DR: In this work, the cytotoxicity and toxicity of phosphonium-based deep eutectic solvents with three hydrogen bond donors, namely glycerine, ethylene glycol, and triethylene glycol were investigated.

TL;DR: A meta-analysis comparing the relative sensitivities and average durations of behavioral studies to those assessing acute lethality, development and reproduction concludes that behavioral studies are comparatively fast and sensitive, and warrant further attention as tools for assessing the toxicological effects of environmental contaminants.

TL;DR: The present results demonstrated that Rahnella sp.

TL;DR: Altered processes and mineral crystallization on the inner shell surface are presented here as a perspective tool for environmental studies because sclerochemistry is in its infancy and cannot be reliably used to provide insights into the pollution history recorded in shells.
