A wide range of unregulated chemicals synthetic origin or derived from natural sources, which may be a contender for future regulations are called Emerging Contaminants (ECs). The concentration ECs ranges ng/L to μg/L, is comparatively smaller as compared other pollutants present in water and wastewater. Even though the environmental low, still possess great threat humans ecosystem. These compounds being widely studied due their potential health effects, pervasive nature, difficult degradation through conventional techniques. Pharmaceutical active (PhACs) pharmaceutical contaminants (PCs) one major groups can cause inimical effect on living organisms even at very lower concentration. don't degrade easily persistent longer periods environment stable structure. With increase demand Pharmaceuticals Personal Care Products (PPCPs), there has been sharp these bodies. This mainly inefficiency wastewater treatment plants removal PhACs. proper identification development techniques crucial recent times. review represents comprehensive summary PCs, various PCs an overview approaches systems available removal. Efficient effective methods useful completely eradicating making bodies safe use. So, investment capital time research beneficial future.

402Emerging pollutants of severe environmental concern in water and wastewater: A comprehensive review on current developments and future research
Water-Energy Nexus, Год журнала: 2023, Номер 6, С. 74 - 95
Опубликована: Авг. 30, 2023
Environmental contaminants have emerged significantly due to the enormous consumption of medications, personal-care products, antibiotics, and hormones for cosmetic health reasons. Emerging pollutants (EPs), often alluded as contaminants, become a massive concern entire populace their immense critical environmental human hazards. EPs broad range effects. emanate from either or animal origins, with ability permeate streams instantaneously gradually through soils. Consequently, potable water sources will get tainted, quality degrade, conditions emerge. For more than decade, research has been conducted on various pollutants, but this developing class mainly comprises those fertilizer, pharmaceutical, personal care industries. Even in lower quantities, majority evolving may be harmful people marine life. These chemicals lack defined limits because treatment facilities require sources. The prevalence deterioration aquatic environments, particularly surface groundwater, is severe problem. technologies utilize methodologies, including physicochemical, biological, modern oxidation processes, regardless benefits limitations.

160Influences of key factors on river water quality in urban and rural areas: A review
Case Studies in Chemical and Environmental Engineering, Год журнала: 2023, Номер 8, С. 100424 - 100424
Опубликована: Июль 22, 2023
Water quality in rivers is deteriorating urban and rural areas due to natural anthropogenic factors. Understanding how changes factors affect river water crucial for managing basins. This review focuses on analyzing key affecting quality, the temporal spatial variations of flowing areas. Natural processes such as weathering rocks, evapotranspiration, atmospheric deposition, climate change, disasters cause water. Anthropogenic could stem from industrial effluents, domestic activities, agricultural activities application fertilizers, manures, pesticides, animal husbandry irrigation practices, deforestation, aquaculture. The seasonal are discussed, land use or cover parameters a negative positive way. In addition traditional contaminants biodegradable organic matter, heavy metals, pathogens, emerging persistent pollutants organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), perfluoroalkyl polyfluoroalkyl substances (PFASs), phamaceutic active compounds (PhACs) has been found many rivers, which pose threat human health. comparison also clarified, provides authorities policymakers with deep understanding supports decision-making sustainable management.

78Antibacterial Activity of Solvothermal Obtained ZnO Nanoparticles with Different Morphology and Photocatalytic Activity against a Dye Mixture: Methylene Blue, Rhodamine B and Methyl Orange
International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(6), С. 5677 - 5677
Опубликована: Март 16, 2023
In this paper, we report the synthesis of ZnO nanoparticles (NPs) by forced solvolysis Zn(CH3COO)2·2H2O in alcohols with a different number -OH groups. We study influence alcohol type (n-butanol, ethylene glycol and glycerin) on size, morphology, properties obtained NPs. The smallest polyhedral NPs (<30 nm) were n-butanol, while measured average 44 nm rounded. Polycrystalline particles 120 glycerin only after water refluxing. addition, here, photocatalytic activity, against dye mixture, three model pollutants: methyl orange (MO), methylene blue (MB), rhodamine B (RhB), closer to real situations where is polluted many chemicals. All samples exhibited good activity degradation efficiency reaching 99.99%. sample maintained high >90%, over five catalytic cycles. Antibacterial tests conducted Gram-negative strains Salmonella enterica serovar Typhimurium, Pseudomonas aeruginosa, Escherichia coli, Gram-positive Enterococcus faecalis, Bacillus subtilis, Staphylococcus aureus, cereus. presented strong inhibition planktonic growth for all tested strains, indicating that they can be used antibacterial applications, such as purification.

70Advanced Polymeric Nanocomposite Membranes for Water and Wastewater Treatment: A Comprehensive Review
Polymers, Год журнала: 2023, Номер 15(3), С. 540 - 540
Опубликована: Янв. 20, 2023
Nanomaterials have been extensively used in polymer nanocomposite membranes due to the inclusion of unique features that enhance water and wastewater treatment performance. Compared pristine membranes, incorporation nanomodifiers not only improves membrane performance (water permeability, salt rejection, contaminant removal, selectivity), but also intrinsic properties (hydrophilicity, porosity, antifouling properties, antimicrobial mechanical, thermal, chemical stability) these membranes. This review focuses on applications different types nanomaterials: zero-dimensional (metal/metal oxide nanoparticles), one-dimensional (carbon nanotubes), two-dimensional (graphene associated structures), three-dimensional (zeolites frameworks) nanomaterials combined with polymers towards novel polymeric nanocomposites for applications. will show combinations impart enhanced into membrane; however, underlying issues modification processes environmental impact are less obvious. highlights utility computational methods toward understanding structural functional Here, we highlight fabrication methods, advantages, challenges, impact, future scope advanced based systems

The over-consumption, inappropriate use and dumping of pharmaceutical products have had adverse effects on ecosystems. presence contaminants in surface waters drinking water is worldwide concern, due to their ability produce physiological even at low concentrations humans animals. These compounds find way into the environment mainly through human animal waste, mode action persistence are among today's major environmental challenges. Traditional wastewater treatment methods used address these challenges many significant drawbacks. In response, adsorption gaining popularity within scientific community its high performance, cost, ease handling diversity adsorbents. This review highlights application a variety adsorbents for efficient removal pharmaceuticals from different media.
