Adverse health and environmental outcomes of sewage treatment plant on surrounding groundwater with emphasis on some mitigation recommendations

Water quality deterioration hinders economic and social development in developing countries that are facing freshwater security and shortages. Based on the collection of 29 water samples, this study focused on the relationship between sewage treatment plant and groundwater system surrounding it using multidisciplinary approach that combines the characterization of groundwater system and its connection with surrounding canal and drains, using chemical and isotopic characterization revealing that there is a direct relation between the surface water system and surrounding groundwater system. About 58% of the groundwater samples and all surface water samples in the investigated area are threatened by high concentrations of trace elements. The multivariate statistical analysis elucidates that anthropogenic effect and fertilizers sewage contamination are the main causes of groundwater pollution. Nearly, 31 …

Sorption and transport characteristics of europium on sandy soils

Radioactive europium can be released as a fission product during nuclear incidents and pose a threat to the human and surrounding environment because of its biological activity and long decay half-lives. For safe design issues and human health protection demands in construction of the planned nuclear power plants (NPPs) at Al-Dabaa site, it is necessary to study the sorption and transport of different radionuclides as europium within the selected area for predicting their fate at any crisis. Many soil samples were collected from different locations at the area selected along the northwestern coast of Egypt. The samples were transported to the laboratory, preserved, and characterized using X-Ray fluorescence (XRF), Fourier transform infrared spectroscopy (FT–IR), and X-Ray diffraction (XRD). Experiments were performed to study the sorption and transport kinetics of Eu(III) ions on two sandy soil samples from the …

Pharmacoinvasive versus invasive-only strategies in therapy of ST-Elevation Myocardial Infarction: Comparative study

Background Primary percutaneous coronary intervention (PCI) for ST- elevation myocardial infarction (STEMI) remains the default strategy. However, when primary PCI cannot be performed expeditiously, a pharmacoinvasive strategy of fibrinolysis followed by PCI may be a reasonable alternative.Aim of the Study This study is conducted to determine whether pharmacoinvasive strategy using fibrinolysis followed by routine early PCI represents a reasonable alternative to primary PCI when it is not readily available especially in patients with STEMI presenting early after symptom onset.Patients and Methods This is an observational prospective comparative single-center study conducted on acute STEMI patients who are presented within 12 hours from onset of symptoms at cardiovascular medicine department, Mansoura University Hospital in the period from 1st February 2017 till 28thFebruary 2019. The study includes two groups of STEMI patients; pharmaco-invasive group involving 43 patients and primary PCI group involving 51 patients with a one month follow up comparing the safety and efficacy.Results Pre-PCI Thrombolysis in Myocardial Infarction (TIMI) grade was better in pharmaco-invasive group (p=0.017) while there was no statistically significant difference in post PCI TIMI grade. Post-PCI myocardial perfusion grade was better in pharmaco-invasive group (P = 0.045). There was no statistically significant difference between the two groups regarding in-hospital complications(p=0136) or complications at 1 month follow up (P ˃ 0.05). Conclusion A pharmaco-invasive strategy is non-inferior to primary PCI in terms of reperfusion and …

A comprehensive study for the potential removal of 152+ 154Eu radionuclides using a promising modified strontium-based MOF

A facile modification of a strontium-based MOF using oxalic acid was carried out to prepare MTSr-OX MOF, which was used as a potential substance for eliminating 152+154Eu radioisotopes. Various analytical techniques were used to characterize MTSr-OX-MOF. The prepared MOF had a rod-like structure with a BET surface area of 101.55 m2 g−1. Batch sorption experiments were used to investigate the sorption performance of MTSr-OX-MOF towards 152+154Eu radionuclides where different parameters like pH, contact time, initial 152+154Eu concentration, ionic strength, and temperature were scrutinized to determine the optimum conditions for 152+154Eu removal. MTSr-OX-MOF showed superior effectiveness in the elimination of 152+154Eu with a maximum sorption capacity of 234.72 mg g−1 at pH 3.5. Kinetics fitted with the pseudo-second-order model and the Langmuir model correctly described the …

Recent progress in high-performance environmental impacts of the removal of radionuclides from wastewater based on metal–organic frameworks: a review

The nuclear industry is rapidly developing and the effective management of nuclear waste and monitoring the nuclear fuel cycle are crucial. The presence of various radionuclides such as uranium (U), europium (Eu), technetium (Tc), iodine (I), thorium (Th), cesium (Cs), and strontium (Sr) in the environment is a major concern, and the development of materials with high adsorption capacity and selectivity is essential for their effective removal. Metal–organic frameworks (MOFs) have recently emerged as promising materials for removing radioactive elements from water resources due to their unique properties such as tunable pore size, high surface area, and chemical structure. This review provides an extensive analysis of the potential of MOFs as adsorbents for purifying various radionuclides rather than using different techniques such as precipitation, filtration, ion exchange, electrolysis, solvent extraction, and …

Adsorption of yttrium (III), neodymium (III), gadolinium (III), samarium (III), and lutetium (III) ions using 8-hydroxyquinoline intercalated bentonite

Due to the high cation exchange capacity, depressed permeability, low cost, and massive specific surface area, bentonite has crucial importance in the disposal of radioactive waste from their aqueous solutions. Here, the intercalation of 8-hydroxyquinoline onto the surface of Na-bentonite was carried out and the obtained material was used to explore the sorption conduct of lanthanides metal ions from their solutions. X-ray fluorescence, X-ray powder diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, and transmission electron microscopy spectra were done to characterize unmodified and modified bentonite. The changes in the environmental parameters such as contact time, solution pH, sorbent mass, initial concentration, and temperature were optimized. Sorption isotherm was simulated by Langmuir and Freundlich equations and the outcomes revealed that the Langmuir model was appropriate for the sorption of lanthanides onto 8-hydroxyquinoline bentonite (HQ-bentonite) and the maximum sorption capacities values were found to be 26.1, 47.6, 32.6, 39.2, and 40.9 mg/g for Y3+, Nd3+, Gd3+, Sm3+, and Lu3+, respectively, at 303 K. On the other hand, the regeneration studies were investigated with various reagents.

A novel strontium-based MOF: synthesis, characterization, and promising application in removal of ¹⁵²⁺ ¹⁵⁴Eu from active waste

Removal of hazardous radioactive materials such as ¹⁵²⁺¹⁵⁴Eu from active waste using the batch approach has attracted attention nowadays. In this work, a novel melamine–terephthalic strontium metal–organic framework (MTSr-MOF) was prepared via a hydrothermal method. The MTSr-MOF was characterized by various analytical techniques such as FT-IR, ¹H/¹³C-NMR, mass spectroscopy, XPS, XRD, TGA, BET, FE-SEM/EDX, TEM, and UV. The obtained data revealed that MTSr-MOF exhibited brick-like building blocks that were bridged together by the linkers, and each block had a thickness of ∼120 nm. The BET surface area was 74.04 m² g⁻¹. MTSr-MOF was used for the removal of ¹⁵²⁺¹⁵⁴Eu radionuclides from active waste. Further functionalization using various modifiers, including oxalic acid, EDTA, sulfuric acid, and sodium hydroxide was carried out to improve the sorption efficiency of MTSr-MOF towards ¹⁵²⁺¹⁵⁴Eu radionuclides. Among them, MTSr-MOF modified with oxalic acid (MTSr-OX-MOF) demonstrated a superior removal efficiency toward ¹⁵²⁺¹⁵⁴Eu radionuclides when compared to MTSr-MOF or other published reports, with a removal efficiency of more than 96%. The higher sorption efficiency of the MTSr-OX-MOF indicates that it could be a promising candidate for the removal of ¹⁵²⁺¹⁵⁴Eu radionuclides from radioactive waste

Facile synthesis of nanosized samarium titanate (Sm 2 Ti 2 O 7) powders: structural, composition, thermal stability, optical and magnetic properties

Samarium titanate nanopowders have been successfully synthesized from their corresponding precursors through a facile modified sol–gel route. The XRD pattern of the calcined sample at 1100 °C showed that the prepared materials are composed mainly of Sm2Ti2O7 as a predominant phase. SEM images showed that the morphology of the materials changed from amorphous to crystalline agglomerated nanoparticles upon calcination of the as-precipitated sample at 400 to 1100 °C. The crystallite size of the calcined sample at 800 °C was in the range of 20–50 nm as calculated from the TEM images. UV-vis spectra revealed the presence of one absorption peak at around 307 nm for all samples and the band gap is about 3.13 eV on average. One emission peak around 360 nm (3.44 eV) was observed for all samples upon excitation at wavelengths of 240, 250, 265 and 320 nm of the dispersed powders in ethyl …
