Membrane-based water and wastewater treatment technologies: Issues, current trends, challenges, and role in achieving sustainable development goals, and circular economy
This study first focuses on reporting the current membrane-based technologies, i.e. nanofiltration, ultrafiltration, microfiltration and forward- and reverse-osmosis membranes. The second part of this study deeply discusses the contributions of membrane-based technologies in achieving the sustainable development goals (SDGs) stated by the United Nations (UNs) in 2015 followed by their role in the circular economy. In brief, the membrane processes directly impact 15 out of 17 SDGs which are SDG1, 2, 3, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16 and 17. However, the merits, challenges, efficiencies, operating conditions and appli...

Thermal kinetics of PFAS and precursors in soil: Experiment and surface simulation in temperature-time plane
Chemosphere. 2023 Jan 28:138012. doi: 10.1016/j.chemosphere.2023.138012. Online ahead of print.ABSTRACTPer- and polyfluoroalkyl substances (PFAS) are chemically and thermally stable due to the presence of carbon-fluorine (C-F) bond in their molecular structures, hence have been previously formulated as firefighting ingredients. During the firefighting process, however, owing to the high temperature, PFAS can be potentially degraded, particularly for PFAS precursors that contain non-C-F bonds, which is studied herein by exposing PFAS-contaminated soil in a muffle furnace oven. Different temperatures and time intervals are a...

Effects and mechanisms of plant growth regulators on horizontal transfer of antibiotic resistance genes through plasmid-mediated conjugation
This study indicated that widespread use of PGRs in agricultural production could affect the HGT of ARGs via plasmid-mediated conjugation, and the application of reasonable concentrations of PGRs could reduce the ARG transmission in both soil environments and plants.PMID:36720410 | DOI:10.1016/j.chemosphere.2023.137997 (Source: Chemosphere)

Comparative study on effects of pH, electrolytes, and humic acid on the stability of acetic and polyacrylic acid coated magnetite nanoparticles
This study suggested that carboxyl coatings with higher molecular weights and pKa values could stabilize MNPs better due to stronger electrostatic and additional steric repulsion. However, in the presence of HA, these two forces were mainly controlled by adsorbed HA instead of the organic pre-coatings on MNPs.PMID:36720411 | DOI:10.1016/j.chemosphere.2023.137992 (Source: Chemosphere)

Recent advances in CO < sub > 2 < /sub > fixation by microalgae and its potential contribution to carbon neutrality
Chemosphere. 2023 Jan 28:137987. doi: 10.1016/j.chemosphere.2023.137987. Online ahead of print.ABSTRACTMany countries and regions have set their schedules to achieve the carbon neutrality between 2030 and 2070. Microalgae are capable of efficiently fixing CO2 and simultaneously producing biomass for multiple applications, which is considered one of the most promising pathways for carbon capture and utilization. This work reviews the current research on microalgae CO2 fixation technologies and the challenges faced by the related industries and government agencies. The technoeconomic analysis indicates that cultivation is th...

Ozone precursors and boundary layer meteorology before and during a severe ozone episode in Mexico city
Chemosphere. 2023 Jan 28:137978. doi: 10.1016/j.chemosphere.2023.137978. Online ahead of print.ABSTRACTVolatile organic compounds (VOCs) data in conjunction with other inorganic pollutants, surface meteorological data and continuous measurement of the Planetary Boundary Layer height (PBLH) at an urban site in Mexico City were performed from 6 to 18 March 2016. Positive Matrix Factorization (PMF) identified four emission source factors of VOCs along with equivalent black carbon (eBC), gaseous pollutants (CO, NO, NO2, SO2, NH3) and ions (Na+, Mg2+, Ca2+, NO3-, NH4+): (1) secondary aerosol precursors, (2) evaporation and non-...

Simultaneous removal of aqueous same ionic type heavy metals and dyes by a magnetic chitosan/polyethyleneimine embedded hydrophobic sodium alginate composite: Performance, interaction and mechanism
Chemosphere. 2023 Jan 28:137869. doi: 10.1016/j.chemosphere.2023.137869. Online ahead of print.ABSTRACTHeavy metals and azo dyes caused huge harm to the aqueous system and human health. A magnetic chitosan/polyethyleneimine embedded hydrophobic sodium alginate composite (MCPS) was designed and prepared to simultaneously remove aqueous same ionic type heavy metals and azo dyes. In mono-polluted system, the optimal pH for Cr(VI), MO (methyl orange), Cu(Ⅱ) and MB (methylene blue) were 3, 2, 6 and 12 with a saturated adsorption capacity of 87.53, 66.41, 351.03 and 286.54 mg/g, respectively. Pseudo-second-order was suitable t...

Discovery of anomalous molybdenum enrichment in ordovician and silurian stone coal: Relevance, origin and recommendations
Chemosphere. 2023 Jan 28:137975. doi: 10.1016/j.chemosphere.2023.137975. Online ahead of print.ABSTRACTMolybdenum (Mo) is a strategic element but has a notably low concentration at the Earth's surface. Consequently, competition for molybdenum resources at the national strategic level has begun to emerge, and in recent years, large-scale mining has led to the gradual depletion of molybdenum deposit resources. Here, thirty-four element enrichment patterns of Ordovician and Silurian stone coals in central China are reported. Molybdenum is the most enriched element, with an average of 208 mg/kg (58.2-440 mg/kg), which is 99 ti...
