Antibiotics, algal evaluations and subacute effects of abattoir wastewater on liver function enzymes, genetic and haematologic biomarkers in the freshwater fish, Clarias gariepinus

Abattoirs are positioned close to freshwaters in most developing countries where untreated wastewaters are discharged into with potential risk to aquatic life such as fish and ultimately human health. We assessed physicochemical parameters, antibiotics (oxytetracycline and diclofenac) and algal load of effluent collected from a major abattoir in Nigeria. Furthermore, liver function enzymes, genotoxic and haemotoxic effects of subacute concentration (10% of 96 hLC(50) value) of the wastewater were evaluated over a period of 28 d in Clarias gariepinus (The African Sharptooth Catfish). The 96 hLC(50) value of the abattoir wastewater against C. gariepinus was 154.14 mL/L (15.4%). Nitrates, phosphates, sulphates, chloride, ammonia, TDS, TSS, BOD5 and heavy metals (Fe and Pb) in the wastewater were above permissible limits while diclofenac and oxytetracycline were below detection limit (BDL). Microalgae in the wastewater were mostly Bacilliariophyta (Navicula spp.) (45.64%) and euglenoids (Euglena and Phacus spp.) (49.48%). Liver function enzymes (LDH, AST, ALT) level were higher in exposed fishes except for ALP which was lower at day 28 compared to control levels. Erythrocytic genotoxic indices (nuclear abnormalities) were significantly higher (p < 0.05) in the exposed fishes particularly at day 28 compared to control. Haematologic indices level such as WBC, MCV MCH, MCHC increased significantly (p < 0.05) while lymphocytes, HGB, RBC, HCT levels decreased significantly (p < 0.05) in the exposed C. gariepinus by day 28 compared to control. These results demonstrate potential adverse effects posed to aquatic fish species in the Ogun River by the discharge of the abattoir effluent. The microalgae species identified in the effluent may be explored for pre-treatment of the effluent before discharge in order to prevent eutrophication and increased pollutant load in the River. The study results will contribute to evidence-based environmental risk management of the River which is relevant to the UN SDGs 6 (clean water and sanitation), 11 (sustainable cities and communities) and 14 (sustaining life below water). But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 50-84-0, you can contact me at any time and look forward to more communication.

Cellulose extraction from methyltrioctylammonium chloride pretreated sugarcane bagasse and its application

Cellulose, the most abundant feedstock of chemicals and energy is extracted from various agro-industrial wastes, such as sugarcane bagasse (SB). Pretreatment of SB with ionic liquids improves extraction of cellulose, yet the use of ionic liquid is hindered by its high cost. In this study, cellulose was extracted from SB pretreated with methyltrioctylammonium chloride under relatively mild conditions. The extracted cellulose from pretreated SB (PTB) and untreated SB (UTB) was characterized by scanning electron microscopy and FTIR. Fermentation of cellulose extracted from PTB by a thermophilic bacterium, Bacillus aestuarii UE25, yielded 245.16% higher titers of cellulase than cellulose extracted from UTB. The recyclability of the IL was assessed to make the pretreatment process cost effective and was monitored through TLC and FTIR. The results of this research demonstrated the potential of ionic liquid pretreated SB for cellulose extraction and for its subsequent utilization in thermostable cellulase production.

Sacrificial coating development for biofouling control in membrane systems

Current cleaning strategies for biofouling control on spiral wound membrane systems used for seawater desalination are not effective and can hinder long-term membrane performance. To enable effective cleaning of a membrane, we examined the in-situ application and the use of a sacrificial multilayer polyelectrolyte coating on the membrane surface. The membrane coating was based on a layer-by-layer assembly approach using two nontoxic linkers, poly (diallyl-dimethyl ammonium chloride) and poly(sodium-4-styrene sulfonate). This polyelectrolyte coating was effectively applied on the membrane surface under cross-flow conditions, and it was stable on the membrane surface under continuous operation. Coating removal requires only a concentrated sodium chloride solution (synthetic brine in our study) adjusted to pH 11. Using this procedure, both the biofilm and the sacrificial layer could be simultaneously removed, leaving a clean surface compared to the non-coated membrane. Biofouling tests showed that the coated membrane had two-fold higher permeate flux recovery than the control non-coated membrane. The used polyelectrolyte sacrificial coatings avoided the use of toxic linkers and harsh cleaning chemicals, and thus it is a suitable technique for biofouling control on reverse osmosis spiral wound membranes.

Influence of typical electrolytes on electrooxidation of bio-refractory reactive dye

Electrochemical oxidation is a promising alternative for the degradation of reactive dyestuffs in residual dyeing liquid, which contains organic dyes, as well as salts such as sodium chloride and sodium sulfate. In this work, three kinds of salts, Na2SO4, NaCl and FeSO4, were selected to study the influence of electrolytes on the electrochemical oxidation of recalcitrant reactive red X-3B, using graphite cathode and dimensionally stable anode or graphite anode. The removals of color and chemical oxygen demand have been evaluated. Color removals were 99.97% and 99.84% with graphite anode and dimensionally stable anode in Na2SO4 and NaCl electrolyte. The corresponding chemical oxygen demand removals were 93.60% and 100%. In contrast, the maximum color and chemical oxygen demand removals were 97.32% and 68.76% in FeSO4 electrolyte. It was found that a combination of NaCl and FeSO4 achieved complete oxygen demand removal for both graphite anode and dimensionally stable anode. During the electrochemical oxidation process, anode and electrolyte exhibited a great effect on pH variations. Based on the cyclic voltammetry and active oxidative species investigations, the oxidation of reactive red X-3B was attributed to indirect oxidation of active chlorine and reactive oxygen species.

Recent advances in chemical admixtures for improving the workability of alkali-activated slag-based material systems

The early reaction process of alkali-activated slag (AAS) systems is much faster than that of Portland cement systems, resulting in rapid setting. Therefore, fluidity control and setting adjustment are two critical issues for practical applications of AAS; these issues are usually addressed using chemical admixtures. This paper reviews the current research progress in the field of chemical admixtures to improve the workability and setting time of AAS systems. The stability of different superplasticizers, including vinyl copolymers (V), melamine (M), lignosulfonate (LS), naphthalene (N) and polycarboxylate (PCE), in different alkaline activator solutions is summarized and is important in terms of their dispersion performance in AAS systems. The nature of alkaline activators has a significant influence on the performance of the polymers. Moreover, the effects of different superplasticizers and retarders on the workability, setting time and mechanical properties of the AAS systems are discussed. This review provides guidance for improving the AAS performance by superplasticizers and retarders to promote the application of AAS in construction engineering. (C) 2020 Elsevier Ltd.

Fast Synthesis of CeO2 Nanoparticles in a Continuous Microreactor Using Deep Eutectic Reline As Solvent

Hydrothermal methods have conventionally enabled the synthesis of a wide range of nanomaterials. However, these simple, single-step syntheses lack scalability due to the need of high temperatures and autogenous pressures to enable the dissolution of reagents and crystallization of the product. In this work, we demonstrate for the first time fast continuous synthesis of ceria nanoparticles at moderate conditions through the combination of the deep eutectic solvent reline (an eutectic mixture of choline chloride and urea) as reaction medium and the high heat and mass transfer rate offered by microreactors. Almost 100% yields are obtained within 100 s of residence time at 160 degrees C, with some conversion achieved even at temperatures as low as 120 degrees C. Such rapid synthesis takes place thanks to the molecular structure of the solvent which facilitates the fast nucleation of cerium oxycarbonate as an intermediate product. As expected in a kinetically controlled system, pressure and initial cerium concentration have negligible effects on the yield obtained. The rapid reaction, the cheap, benign, and environmentally friendly solvent, and the lack of additional additives in this work opens the door to sustainable large-scale continuous synthesis of ceria nanoparticles as well as other nanostructured materials.

Microplastics with cadmium inhibit the growth of Vallisneria natans (Lour.) Hara rather than reduce cadmium toxicity

Microplastics and heavy metals are discharged into a freshwater environment either directly or via surface runoff and are largely deposited in sediments, posing risks to aquatic organisms. Few studies have thus far been devoted to the interaction of microplastics and heavy metals in sediments. Whether microplastics can affect the toxicity and accumulation of heavy metals in submerged macrophytes remains unclear. We evaluated the effects of polyvinyl chloride microplastics (PVC-MPs) and cadmium (Cd) exposure levels (0, 5, 15, and 25 mg) on Vallisneria natans (Lour.) Hara grown in sediment in a microcosm experiment for 14 d. In this study, PVC-MPs decreased the fresh weights of V. natans in the absence of Cd and markedly reduced the fresh weights at 5 and 15 mg Cd exposure levels. Moreover, PVC-MPs substantially increased the malondialdehyde (MDA) content of V. natans leaves at a Cd exposure of 25 mg. However, the PVC-MPs neither reduced the Cd concentration nor independently increased the antioxidant enzyme activities of the plants. These findings indicate that microplastics can independently, or jointly with a Cd contaminant, inhibit the growth of submerged macrophytes rather than reduce Cd toxicity. To our knowledge, this study is the first to evaluate the effects of microplastics and Cd exposure in sediments on the growth and physiological traits of submerged macrophytes, which could provide important implications for the interaction and future risk assessment of microplastics and heavy metals in sediments of freshwater ecosystems.

Recovery of pure germanium oxide from Zener diodes using a recyclable ionic liquid Cyphos IL 104

A novel process is developed for the recovery of germanium from the leach liquor of Zener diodes using solvent extraction. Extraction is carried out using a phosphonium ionic liquid, Cyphos IL 104, as an extractant. Preliminary investigations carried out on Ge(IV) extraction using Cyphos IL 104 include influence of various parameters like temperature, equilibration time, and concentration of extractant, chloride ion, and acid on the distribution of Ge(IV). NMR spectrum of Ge(IV)-extractant complex was analyzed to support the proposed extracting species of germanium. Quantitative extraction of germanium is achieved from 7 mol/L HCl onwards using 0.1 mol/L Cyphos IL 104. Optimum conditions for quantitative extraction of Ge from leach liquor of Zener diodes were developed. McCabe-Thiele plots were constructed for the extraction and stripping of Ge(IV) from leach liquor to determine the number of stages required at a particular aqueous/organic phase ratio. Separation of germanium from copper, mercury and iron has been achieved by selective stripping of these metal ions. Germanium is recovered as germanium oxide from the strip solution using NaOH as a precipitating agent. The synthesized germanium oxide is characterized by XRD, FE-SEM and EDX techniques.

Na+/Mg2+ interactions on membrane distillation permeation flux and crystallization performance during high saline solution treatment

Membrane distillation crystallization (MDC) was an effective method for saline solution treatment to simultaneously recovery pure water and salt products. In MDC process, an important topic was the influence of ionic interactions produced by complex salt solution on MDC performance. We processed a typical ternary saturated solution (Na+/Mg2+//CF-H2O) with MDC to investigate the influence of different Na+/Mg2+ ratios on membrane distillation permeation flux and crystal morphology from the perspective of experiment and molecular dynamics simulation. From the simulation results, it was demonstrated that increasing magnesium ions could modify the hydration structure of the cations and influence the diffusion coefficient of the hydrated ions in the solution. The reduced free water and diffusion ability led to the changes in permeation flux and crystal morphology. The crystals with different morphologies could be produced by adjusting the ratio of Na+/Mg2+ and MDC temperature. In addition, selective solvent (ethanol) wash approach was developed to further improve the separation performance and reveal the effect of Mg2+ on NaCl crystal growth.

Screening of Concentration and Antimicrobial Effectiveness of Antimicrobial Preservative in Betastatin Besylate Nasal Spray

Objective. To explore the optimal concentration and antimicrobial effectiveness of antimicrobial preservative in betastatin besylate nasal spray. Methods. By using Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Aspergillus niger as test strains, the antimicrobial effectiveness of betastatin besylate nasal spray containing different concentrations of antimicrobial preservative (0.02%, 0.0125%, and 0.005% benzalkonium chloride, respectively) was determined by using bacteriostatic effect test (Chinese Pharmacopoeia, 2015 edition). Results. The antimicrobial effectiveness of betastatin besylate nasal spray containing 0.02% and 0.0125% benzalkonium chloride, respectively, complied with the regulations of Chinese Pharmacopoeia (2015 Edition) against five test strains. However, the antimicrobial effectiveness of betastatin besylate nasal spray containing 0.005% benzalkonium chloride against P. aeruginosa did not meet the requirements of Chinese Pharmacopoeia. Conclusion. Benzalkonium chloride at a concentration of 0.125% can be used as an added antimicrobial preservative in betastatin besylate nasal spray.
