TL;DR: Advanced Oxidation Processes (AOPs) are called to fill the gap between the treatability attained by conventional physico-chemical and biological treatments and the day-to-day more exigent limits fixed by environmental regulations.

TL;DR: In this review, different types of composting methods reportedly applied in waste management were explored and the major factors such as temperature, pH, C/N ratio, moisture, particle size, and relevant strategies to improve and optimize process effectiveness were addressed.

TL;DR: It was evident that some clays have appreciable adsorption capacities on top of being widely available and the application of clay minerals for decolourising water represents economic viable and locally available materials that can be used substantially for pollution control and management.

TL;DR: The population exposed to Bangshi River water remained at carcinogenic and non-carcinogenic health threat and the risk was higher for adults, and deterministic and probabilistic estimations of cancer risk through exposure to groundwater were well below the safety limit.

TL;DR: Based on TOC analysis, mineralization was 37% in the same reaction conditions for initial tetracycline concentration of 10 mg/L and reached to 83% after 300 min and Pseudo-first order kinetic model was best fitted with the experimental results.

TL;DR: A review on quality of sewage sludge based on the publications after 2010 has been presented and there are several papers focusing on new serious threats to human health and ecosystem occurring in sewageSludge.

TL;DR: A baseline for understanding research needs to better develop treatment technologies for PFOA and PFOS in groundwater is provided and the development and demonstration of promising in situ treatment technologies at the pilot and full scale are demonstrated.

TL;DR: Results show that the COSHTC3 prepared from low-cost agricultural waste with average pore diameter 28.6 Å and surface area 876.14 m2/g acts as a better adsorbent for removal of cationic dyes and could pave the way for more low- cost adsorbents for dye removal.

TL;DR: In this review, the detailed information on different types of OC pesticides, their metabolites, environmental concern and present status on degradation methods using nanoparticles have been reviewed.

TL;DR: Seven hypotheses for future research are highlighted under three themes: design and optimization of bio char water treatment; ecotoxicology and human health risks associated with contaminant transfer along the biochar-soil-food-human pathway, and life cycle analyses of carbon and energy footprints of biochar water treatment systems.

TL;DR: The study revealed that factors such as high durability, ease of availability, low density, chemical inertness and mechanical stability are primary factors responsible for the selection of suitable supports for catalysts.

TL;DR: Results from technique and composition effects show that increase in economic growth leads towards more pollution emissions, however, economic growth declines as pollution crosses a certain limit and foreign direct investment is also found positively related with pollution.

TL;DR: It is concluded that in multi-element contamination cases, along with high-toxicity elements, other elements may also be responsible for increasing human health risks (i.e., Mn), due to the possibility of adverse synergism of the PTEs.

TL;DR: This paper reviews recent activities in the development of mesoporous materials as phosphate adsorbents and mainly focuses on the synthesis, properties and phosphate removal efficiency of various materials with mesoporosity, including metal-coordinated amino-functionalized silicas.

TL;DR: The results found that males, older students and those studying Engineering and the Social and Human Sciences are those reporting higher levels of environmental knowledge, however, when it comes to attitudes and behaviours, females seem to display more awareness around these issues.

TL;DR: The three-stage process can be regarded as the effective preparation method of AC with a high adsorption capacity toward the cationic dye andThermodynamic experiments suggested that the MG5 adsorptive process was spontaneous and endothermic, and increased the randomness in the system.

TL;DR: This contribution reviews and presents recent developments for several key aspects of fingerprinting, namely: sediment source classification, catchment source and target sediment sampling,tracer selection, grain size issues, tracer conservatism, source apportionment modelling, and assessment of source predictions using artificial mixtures.

TL;DR: The findings show that most of the barriers to GI stem from cognitive limitations and socio-institutional arrangements, and suggest 33 policies that can both overcome these barriers and expedite implementation.

TL;DR: A monotonically increasing relationship between CO2 emissions and GDP in both MEA and EU regions is found and policy makers should regulate and enhance the role and efficiency of domestic institutions to have sustainable positive economic performance and to reduce carbon dioxide emission.

TL;DR: A novel hybrid model based on principal component analysis (PCA) and least squares support vector machine (LSSVM) optimized by cuckoo search (CS) that outperforms a single LSSVM model with default parameters and a general regression neural network (GRNN) model in PM2.5 concentration prediction.

TL;DR: Activated carbon (AC) adsorbent demonstrated superior performance for all selected NSAIDs, thus being efficient technology for treatment of these pharmaceutical pollutants.

TL;DR: The literature on surfactant types, the synergistic effect of mixed micelles on PAH removal, the impact of surfactants on the PAH biodegradation process, factors affecting the SER process, and the mechanisms of surfACTant-enhanced solubilisation of PAHs are reviewed.

TL;DR: Converting heavy metals into more stable phases during immobilization processes should be a common way to enhance the immobilization effect of these immobilization methods.

TL;DR: Results prove that nZVI/BC can be an effective reagent for removal of Cr(VI) from solutions.

TL;DR: In this article, the authors investigated the socio-psychological behavior of smallholder farmers with regard to sustainable practices and found that social capital, personal efficacy, training and perceived usefulness play significant roles in the decision to adopt sustainable practices.
