“…The broad utilization of these chemicals has prompted growing concerns over their ecotoxicity and widespread availability in terrestrial and aquatic environments as contaminants (Oberg and Leopold, 2019;Atugoda et al, 2020;Puckowski et al, 2021). Most PPCPs comprise of complex organic compounds of bioactive ingredients including pharmaceuticals such as antibiotics (tetracycline, ciprofloxacin, sertraline, propranolol, and sulfamethoxazole), antiseptics, disinfectants, analgesics, and cytostatic hormones, which when released into the aquatic environment could exert harmful effects on human health, biota and the environment (Yin et al, 2017;Dey et al, 2019;Yang et al, 2021). PPCPs are polar and highly hydrophilic organic contaminant (Caliman and Gavrilescu, 2009;Ebele et al, 2017).…”

Microplastics, which serve as sources and vector transport of organic contaminants in both terrestrial and marine environments, are emerging micropollutants of increasing concerns due to their potential harmful impacts on the environment, biota and human health. Microplastic particles have a higher affinity for hydrophobic organic contaminants due to their high surface area-to-volume ratio, particularly in aqueous conditions. However, recent findings have shown that the concentrations of organic contaminants adsorbed on microplastic surfaces, as well as their fate through vector distribution and ecological risks, are largely influenced by prevailing environmental factors and physicochemical properties in the aquatic environment. Therefore, this review article draws on scientific literature to discuss inherent polymers typically used in plastics and their affinity for different organic contaminants, as well as the compositions, environmental factors, and polymeric properties that influence their variability in sorption capacities. Some of the specific points discussed are (a) an appraisal of microplastic types, composition and their fate and vector transport in the environment; (b) a critical assessment of sorption mechanisms and major polymeric factors influencing organic contaminants-micro (nano) plastics (MNPs) interactions; (c) an evaluation of the sorption capacities of organic chemical contaminants to MNPs in terms of polymeric sorption characteristics including hydrophobicity, Van der Waals forces, π–π bond, electrostatic, and hydrogen bond interactions; and (d) an overview of the sorption mechanisms and dynamics behind microplastics-organic contaminants interactions using kinetic and isothermal models. Furthermore, insights into future areas of research gaps have been highlighted.

“…Several LCAs have been developed in recent years for advanced treatments but always in developed countries (e.g. Chatzisymeon et al 2013; Gallego-removal from wastewater of new pollutants like PPCPs that pose significant risks to the environment (Rizzo et al, 2013;Luo et al 2014;Yin et al, 2017). Moreover, there is evidence that the concentrations of some of these compounds, particularly antibiotics, are similar or higher in the wastewaters of developing countries, especially in Asia (Tran et al, 2018;Mohapatra et al, 2016).…”

Life cycle assessment of wastewater treatment in developing countries: A review

Within developing countries, wastewater treatment (WWT) has improved in recent years in but remains a high priority sustainability challenge. Accordingly, life cycle assessment (LCA) studies have recently started to analyse the environmental impacts of WWT technologies on the specific context of less developed countries, mainly in China and India. This work presents a comprehensive review of this knowledge with the aim of critically analysing the main conclusions, gaps and challenges for future WWT-related LCAs in developing countries. The most commonly assessed technologies in the 43 reviewed articles are different variations of activated sludge and extensive treatments applied in decentralized systems; however, studies focused on advanced technologies or new sources of pollution (e.g. micropollutants) are still lacking. Goal and system boundaries are normally clearly defined, but significant stages for some technologies such as the construction and sludge management are frequently not included and functional units should be defined accordingly to specific conditions in developing countries. At the inventory level, a more concise description of sources and technical parameters would greatly improve the quality of the LCAs along with accountability of direct greenhouse gas emissions. Eutrophication and global warming are the two

“…For instance, degradation processes such as ozonation or chlorination were proven efficient for the degradation of organic molecules [6,7]. However, these techniques have high operational costs and often cause dangerous degradation by-products that would follow the water flow and end up in rivers and lakes [8].…”

The threat of pharmaceutical residues in natural waters is a pressing concern in both developed and underdeveloped countries. Originating mostly from municipal and farms effluents, pharmaceuticals, poorly eliminated by traditional wastewater treatments enter the environment through sewage treatment plants discharges. Their adsorption on ecological adsorptive materials such as lignin may represent an interesting remediation solution. The present study sets out the sorption capacities and properties of a newly developed lignin-based nanofibrous material for typical pharmaceutical residues (fluoxetine, venlafaxine, ibuprofen, and carbamazepine) found in surface waters. This green biomaterial showed, in addition to its high recovery yield, excellent reusability through desorption (more than 90% recovered). As an example, adsorption levels reached 78 mg/g for adsorption of fluoxetine compared to 5-10, 49 and 75-80 for unfunctionalized silica, zeolites and ionexchange resins respectively. The innovative approach reported therein perfectly meets the concept of circular economy sought in modern societies.
