Cow-dung based sludge acclimatized with the effluent was used for the biological oxidation experiments at a 1:3 sludge to effluent loading for a treatment time of 48 h. Conventional biological oxidation resulted in 48.79% CIP degradation, which was demonstrated to be enhanced through acoustic cavitation-based pretreatment. The optimized conditions for cavitation were 125 W power and a 70% duty cycle, and the optimum oxidant loadings for the combination studies were 150 mg/L H<sub>2</sub>O<sub>2</sub>, 150 mg/L of potassium persulfate (KPS), and 200 mg/h of O<sub>3</sub>. The enhanced CIP degradation after application of pretreatment was 63.27%, 79.23%, 68.27%, and 82.27% for AC, AC + H<sub>2</sub>O<sub>2</sub>, AC + KPS, and AC + O<sub>3</sub> based pretreated effluents, respectively. Toxicity analysis against test organisms <i>Pseudomonas aeruginosa</i> (<i>P. aeruginosa)</i> and <i>Saccharomyces cerevisiae</i> using the agar well diffusion method confirmed that pretreatment reduced the toxicity leading to enhanced biodegradation. Overall, the current work elucidated the efficiency of acoustic cavitation combined with KPS for the effective biological oxidation of ciprofloxacin.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"34 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As they interact with all living organisms, including humans, their mechanism of interaction and their perilous impact must be meticulously investigated. To uncover the secrets of MNPs, there must be model systems that exist to interlink the two major scenarios: they must represent the environmental impact and be relevant to humans. Therefore, zebrafish and <i>Drosophila</i> are perfect to describe these two cases, as they are well studied and relatable to humans. In this review, 39% zebrafish studies reported higher mortality and hatching rates at greater MNP concentrations, severe oxidative stress as seen by raised malondialdehyde (MDA) levels, and reduced superoxide dismutase (SOD) activity. About 50% of studies showed severe neurotoxic behavior with drop of locomotor activity, suggesting neurotoxicity. MNPs have a significant impact on fertility rate of <i>Drosophila</i>. More than half of the studies revealed genotoxicity in <i>Drosophila</i> as observed by wing spot assays and modified genomic expressions associated with stress and detoxification processes. These findings emphasize the potential of MNPs to bioaccumulate, impair physiological systems, and cause oxidative and neurobehavioral damage.

In Ethiopia, the tannery sector is important for exports, economic growth, and employment. However, the tannery industry is the most pollutant generating and environmentally unfriendly industry in the world and recognized as a significant source of pollution of surface waters in Ethiopia. This review aims to assess the characterization, treatment, and impact of tannery wastewater. The authors reviewed 117 published materials, including articles and theses, related to the research area. The review results reveal that Ethiopian tannery effluents contribute to elevated levels of chemical oxygen demand (COD), biological oxygen demand (BOD), total dissolved solids (TDS), chromium (Cr), sulfide (S<sup>2−</sup>), and total nitrogen, which exceed national discharge limits and compromise water quality in rivers, notably the Little Akaki River. The adverse effects extend to soil and agricultural produce, posing significant risks to public health. Conventional treatment methods are widely used in the treatment of tannery wastewater but have limited effectiveness in meeting regulatory standards. This review emphasizes the urgent need for strengthened policy enforcement and investment in modern treatment technologies to develop sustainable solutions that mitigate the environmental and health impacts of tannery wastewater in Ethiopia. Additionally, nanomaterial-based adsorption and photocatalysis have shown promising results in efficient pollutant removal, further research is recommended in this area.</p>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"34 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tqem.70015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finding ways to improve these nanocomposites for use in photocatalysis is the primary goal of the study. Several methods were used to analyze the nanocomposites, such as field emission scanning electron microscope (FESEM), high resolution transmission electron microscopy (HRTEM), x-ray diffraction (XRD), Fourier transform infrared (FTIR), UV-Vis, x-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Using nanocomposites of nickel cobalt tungstate (Ni<sub>(1-X)</sub>Co<sub>X</sub>WO<sub>4</sub>), the adsorption and photodegradation of acid red (AR) and acid green (AG) from a solution including water were accomplished with success. When exposed to visible light, the nickel cobalt tungstate nanocomposite shows increased rates of adsorption and photodegradation compared to its behavior when no light is present. With an impressive rate of 89.54% AG removal and 87.16% AR removal in less than 60 min, the compound nickel cobalt tungstate showed great potential. When it comes to fighting AG and AR in visible light, photodegradation outperforms adsorption.

The consortium was obtained from sediment that was deposited on the residential properties in southeastern Louisiana after Hurricane Ida in August 2021. A bacterial consortium was developed through an enrichment technique that used phenol as the sole carbon source. Phenol degradation followed a concentration gradient. The consortium was able to remove more than 95% of phenol within 14 days when the phenol concentration was 100 mg/L. However, phenol degradation efficiency decreased when the phenol concentration was increased in the culture medium. The consortium removed 30% of phenol at the highest concentration tested, 1000 mg/L, within 14 days. However, when the incubation time was extended to 70 days, 98% phenol removal was observed in the highest concentration of phenol tested of 1000 mg/L. The consortium was dominated by three distinct phyla and nine distinct genera. The dominant phylum was represented by proteobacteria, and the dominant genus in the consortium was Shigella. The consortium removed phenol via the β-ketoadipate pathway with the production of the following metabolites: cis, cis-muconic acid, succinate, and fumarate. The novelty of this study was the high tolerance of phenol concentration of 1000 mg/L by the bacterial consortium and its ability to degrade phenol without a lag phase.

Heavy metal pollution poses a significant environmental challenge in Malaysia, specifically the five metals focused on in this research: Cd, Cr, Cu, Ni, and Zn. The study evaluates the adsorption capacity of the soil mixture for these metal ions by utilizing laboratory analyses of key parameters such as pH and cation exchange capacity (CEC). To assess the effectiveness of the soil mixture, various combinations were tested, highlighting a blend of 50% LS, 40% PS, and 10% RH as the most effective. An equilibrium study was conducted, wherein metal ion solutions were prepared, allowing the soil mixtures to interact with these solutions until a state of equilibrium was achieved. Subsequently, batch adsorption experiments were performed to measure the mixtures’ ability to adsorb the metal ions, with ongoing assessment of pH and CEC. The results indicate that the selected mixture can significantly reduce metal ion concentrations, demonstrating its potential as a viable daily cover for landfills.
