In this study, a novel adsorbent for the removal of cesium ion in water was developed by the modification of the surface of the SBs with magnetite (Mag) and Prussian blue (PB). The developed adsorbent (PB-Mag-SB) was characterized by elemental analysis, X-ray diffraction, and Fourier transform infrared spectrometry and the magnetism of the adsorbent. From these results and the change in color of the adsorbents, the successful modification of the SBs with magnetite and PB was confirmed. The developed adsorbents were added and mixed with the polluted water. After the adsorption, it could float up on the surface of water due to the buoyancy of the balloon and also be collected by a magnet due to the magnetism of the magnetite formed on the surface of the SB. Furthermore, the removal of Cs from water was achieved by binding site of PB immobilized on the Mag-SB. The PB-Mag-SB could selectively adsorb Cs even in the presence of coexisting cations at high concentrations. The adsorbent remained afloat on the water surface for at least 24 h, and approximately 99% of the adsorbent could be collected within 5 min using a magnet. The introduction of both floating and magnetism properties to the adsorbent makes it easy and selective to collect the adsorbent after the adsorption of pollutants in water. SB is a natural product with a low environmental impact; therefore, the adsorbent based on SB will contribute to the environmental remediation as a novel material for adsorption.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study has evaluated ecological water quality using the comprehensive pollution index (CPI), eutrophication index (EI), and organic pollution index (OPI). Fish community structure has been assessed based on tropic level score (TLC) and habitat orientation score (HOS). Moreover, FHS has been evaluated using the habitat suitability index (HSI). These assessments have been conducted in the spatio-temporal dimension. This study demonstrates that the ecological water quality is significantly poorer during the monsoon (MON) season, according to the CPI. However, it was at its lowest during the pre-monson (PRM) season in 2014-2015 and the post-monson (POM) season in 2022-2023, as indicated by the OPI and EI. The water is significantly polluted downstream of the Durgapur barrage, particularly after the Tamla Nallah confluence. According to the CPI, 72.73% of water samples during the MON season were highly contaminated in 2014-2015 and in 2022-2023. Practically water was badly polluted in all seasons according to the OPI and EI. The fish community composition indicates that the river is currently in a precarious state, and the ecosystems inside the river have undergone alterations in certain areas. According to the HSI, the Damodar River exhibits diminishing appropriateness for fish habitat during PRM season in certain areas, while other seasons show no suitability for fish habitat. This investigation will be highly beneficial for mitigating pollution and restoring rivers. It is crucial to uphold and conserve freshwater biodiversity and the ecosystem services provided by the river.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentration data were first made comparable through an original process removing the bias induced by the space-and-time heterogeneity of the monitoring labs performance, to gather a reference workable set of monthly contamination indicators. These were then used to display the substances' seasonal and interannual timeseries, revealing, e.g. the succession of PPP active substances contamination peaking periods in the 6 basins, or the long-term trends of the concentrations of the various chemicals, sometimes evidencing insufficiencies in the monitoring performance. These environmental observations were put in regard of the knowledge of the substances ban, restriction or reduction measures, to assess how streams' chemical quality responds to them. Additionally, the observed contamination features and their variations over the years are discussed in terms of changes in their usages, product substitution, emission sources, and linked to environmental processes like runoff, river dilution and physicochemical conditions. Some original findings and interpretation are provided on glyphosate and AMPA wide-scale data inter-relation, and some light is cast on the efficacy of the recent national policies restricting pesticides use in populated areas. For PPPs, the developed water contamination indicators were compared to tonnage data. We assessed their degree of linear relationship, which we propose to quantitatively express through a substance specific basin-to-river contamination coefficient. The interannual variations of this coefficient appear to be related to the changes in the water contamination seasonal patterns. We were also able to describe and validate the dependency of this coefficient on the molecular properties of the substances, conferring some capabilities for predicting the relative environmental risk induced by non-yet monitored compounds.

We examined the occurrence of both the essential (Fe, Mn, Cu, and Zn) and toxic (Pb, Cd, Cr, Co, Ni, and As) metals as well as microplastics (MPs).

Furthermore, diverse types of MPs including fibers, fragments, and microbeads were observed in all components of the canal ecosystem. Remarkably, our results unveiled that the co-occurrence of pollutants was more severe in benthic organisms like snails or crabs might be due to their omnivorous food habits. The cumulative pollutant accumulation was much higher in all components of the canal ecosystem indicating a greater ecological risk.

The interaction between V and Ce also promoted the formation of V⁵⁺ and Ce³⁺ on the surface of the catalyst, which was conducive to enhancing the adsorption and oxidation capacity of the catalyst for NO.

The contribution of the different parts of the disinfection system (anode, cathode, and light) was determined. In addition, the efficiency of the UV-LEDs/GDE/DSA system in the disinfection of an irrigation water sample was studied. It was found that the combination of the electrochemical system with UV-LEDs was highly synergistic (φ > 7), having low electric energy consumptions per order of magnitude (E_EO: 1.13 × 10^-2 and 1.55 × 10^-2 kWh/m³ order). Moreover, some differences in the inactivation kinetics and synergy between E. coli and P. aeruginosa were observed and linked to the structural/morphological characteristics of the two bacteria. Remarkably, the electrochemical system combined with low-cost UV-LEDs inactivated both target microorganisms after only 2 min of treatment. The flow cytometry analyses evidenced the damage to the cell membrane of the bacteria by the simultaneous and synergistic action of the electrogenerated H₂O₂ and active chlorine species (ACS), plus the attacks of photo-generated reactive oxygen species. This synergistic combination in the UV-LEDs/GDE/DSA system demonstrated remarkable efficiency in the disinfection of an irrigation water sample, achieving the elimination of culturable bacteria in 45 min of treatment.
