“…When treated with Chlorella pyrenoidosa , Yi et al (2019) discovered that the cytotoxicity of PS particles depended on their size (the IC50 for 0.55 m PS was 9.10 mg/L) but no toxicity was observed for 5.0 m PS. These findings are consistent with previous reports in which the toxicity of PS increased with particle size ( Parsai et al, 2022 ). This result demonstrates that the shading effect is not the primary reason MPs are hazardous to microalgae.…”

“…The authors described this toxicological increase of aged MPs because of surface alterations, including high porosity resulting in surface oxidation, minor partial micro-cracks, and higher crystallinity, which encourage the breakdown into smaller pieces, and bigger specific surface area. When MPs and components are leached, they can interact with aquatic biota of all trophic levels, such as microalgae ( Parsai et al, 2022 ) and aquatic animals like fish, tadpoles, and Eriocheir Sinensis (crab) ( Rowley et al, 2020 ). The quantity of polystyrene particles, their bioavailability to planktonic, nektonic, and bottom-dwelling freshwater biotas, as well as their extensive relative abundance in freshwater compartments, can unavoidably lead to ingestion by different biological creatures ( Law et al, 2010 ).…”

“…Surprisingly, small-size PS microbeads had the same repressive effects on E. gracilis as large-size PS microbeads. The authors noted that the morphology of E. gracilis cells (ellipsoidal or spheroidal) and their larger size (32–55 m in length and 8–9.6 m in diameter) may affect the results ( Guschina et al, 2020 ; Xiao et al, 2020 ; Parsai et al, 2022 ).…”

Microplastic (MP) particles are considered noxious pollutants due to their presence in aquatic habitats at almost every level of the food chain. Thus, the entry of MP particles into marine waterbodies has triggered a common research interest. Until recently, the toxicity of polystyrene towards aquatic creatures in comparison to other polymers has not been widely investigated. This article provides an extensive overview of the occurrence of microplastic particles, the route of polystyrene (PS) in the aquatic ecosystem, the PS properties characterization, and its noxious effects on the aquatic biota, particularly fishes and microalgae. Alarming high levels of polystyrene were found in urban, coastal, and rural surface waters and sediments. The fast-screening technique began with a stereoscope to determine the polystyrene particles’ shape, size, and color on the organism. SEM and complemented by micro FTIR or Raman spectroscopy were used to evaluate MP’s polymer structures. The findings present evidence suggesting that polystyrene buildup in fish can have long-term and unknown consequences. Meanwhile, the presence of polystyrene on microalgae causes a decrease in chlorophyll concentration and photosynthetic activity, which may disrupt photosynthesis by interfering with the electron characters and leading to the production of reactive oxygen species (ROS).

“…1,2 The group of CECs consists mainly of antibiotics, 3 pharmaceutics, 4 steroids, 5 endocrine disruptors, 6 hormones, 7 industrial additives, 8 chemicals from personal care products, 9 other chemicals, 10 and also microbeads and microplastics. 11,12 One of the main concerns are antibiotics and pharmaceutics in general, because they can accumulate in aquatic organisms and consequently in humans with unknown health effects. At the same time, the presence of antibiotics in surface water can lead to the development antibiotic resistant bacteria.…”

Metal-organic frameworks (MOFs) are attracting increasing attention as adsorbents of contaminants of emerging concern which are difficult to remove by conventional processes. However, common carboxylate-based MOFs suffer from low stability in water environment, which limits their environmental applications. In this study, we use phosphinate-based MOFs with higher hydrolytic stability and we focus on the influence of functional groups covering the pore walls on the adsorption of pharmaceutical pollutants present in water – diclofenac, cephalexin and sulfamethoxazole. We present a synthesis of new structures isoreticular to the phosphinate MOF ICR-7. The presented MOFs contain phenyl rings facing the pore walls modified with dimethylamino groups (ICR-8) and ethyl carboxylate groups (ICR-14). These functionalized MOFs were obtained from two newly synthetized phospinate linkers containing the respective functional groups. Generally, the presence of additional functional groups resulted in higher affinity to the tested pollutants in comparison with ICR-7 or activated carbon, however, it also decreased the sorption capacity.

“…Emerging pollutants (or contaminants of emerging concern [CECs]) are compounds that are detected at low levels in surface water and are not commonly monitored/regulated but may have an impact on aquatic life, ecosystems, and human health. , The group of CECs consists mainly of antibiotics, pharmaceuticals, steroids, endocrine disruptors, hormones, industrial additives, chemicals from personal care products, and other distinct chemicals . Studies have also identified microbeads and microplastics as contributors to this category. , Among the array of CECs, antibiotics and pharmaceuticals merit particular attention. Their presence in aquatic environments signals a potential for bioaccumulation within aquatic species.…”

Metal–organic frameworks (MOFs) are attracting increasing attention as adsorbents of contaminants of emerging concern that are difficult to remove by conventional processes. This paper examines how functional groups covering the pore walls of phosphinate-based MOFs affect the adsorption of specific pharmaceutical pollutants (diclofenac, cephalexin, and sulfamethoxazole) and their hydrolytic stability. New structures, isoreticular to the phosphinate MOF ICR-7, are presented. The phenyl ring facing the pore wall of the presented MOFs is modified with dimethylamino groups (ICR-8) and ethyl carboxylate groups (ICR-14). These functionalized MOFs were obtained from two newly synthesized phosphinate linkers containing the respective functional groups. The presence of additional functional groups resulted in higher affinity toward the tested pollutants compared to ICR-7 or activated carbon. However, this modification also comes with a reduced adsorption capacity. Importantly, the introduction of the functional groups enhanced the hydrolytic stability of the MOFs.
