This study investigates nitrate levels in water, soil, and vegetation within an ecosystem influenced by agricultural fertilizers and emissions from a cement plant located 12 km from Constantine and 7 km from Hamma Bouziane, Algeria. This study, conducted from 2013 to 2023, evaluates the evolution of nitrate pollution from industrial and agricultural sources. Nitrate levels were measured using a selective nitrate ion electrode (Reference CI-6735–NO₃⁻). Samples were collected from drinking water, soils surrounding the cement plant, and crops grown in the region. The results indicate a significant reduction in nitrate pollution despite increased production at the cement plant. Nitrite concentrations decreased by 46%, nitrate levels dropped by 24% in surface and groundwater, and by 60% in industrial fallout dust. Reductions of 65.92% were observed in uncultivated soils, 62%–64% in cultivated soils, and 70% in cultivated vegetation. However, the excessive presence of nitrates in water, especially in the wells of AIN S'DARI (El Hamma region), remains a health risk, particularly due to the potential for methemoglobinemia in infants. It was found that nitrogen-based fertilizers are the main cause of nitrate contamination under the greenhouses, while the cement factory's fallout is the primary pollution source for the surrounding lands. These findings underscore the importance of continued nitrate monitoring and the implementation of strategies to minimize their presence in the ecosystem.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"35 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615159","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}

However, its wastewater contains large quantities of organic materials like proteins and fats. Many fish canning industries have wastewater treatment plants (WWTPs) but do not reuse the treated water. Based on the test results, the wastewater characteristics were as follows: BOD content of 10 mg/L, chemical oxygen demand (COD) of 45 mg/L, total coliform of 3500 CFU/100 mL, and Fe concentration of 0.219 mg/L. These values exceed the quality standards required for raw water, highlighting the need for further treatment. To address this, an ultrafiltration (UF) unit was designed to meet the industry's needs and regulatory requirements. The design of the UF unit is planned using the WAVE application, reducing these contaminants to acceptable levels. The proposed UF unit comprises six modules, with a filtration process lasting 30 min and a backwash process lasting 3.4 min. The treated water quality from the UF unit is projected to achieve significant reductions in contaminants, lowering the BOD content to 0.225 mg/L, COD to 1.8 mg/L, total coliform to 0.04 mg/L, and Fe concentration to 0.000003 mg/L.

Traditional surveillance methods, which focus on symptomatic patients, provide a reactive and limited view of resistance trends, often overlooking the early indicators of emerging AMR threats. This review advocates for a paradigm shift in AMR surveillance, emphasizing the potential of wastewater-based epidemiology (WBE) as a proactive, real-time monitoring tool. By harnessing advanced molecular techniques, WBE offers an unprecedented opportunity to track antimicrobial resistance genes (AMRGs) in populations, even in areas with limited healthcare infrastructure. Rather than merely counting pathogens, WBE allows for the detection of subtle shifts in the resistome, providing a clearer picture of resistance dynamics before they reach clinical settings. This approach not only offers early warnings of potential resistance outbreaks but also enables global surveillance, contributing to a more comprehensive understanding of AMR trends and the effectiveness of mitigation strategies. Ultimately, wastewater surveillance is poised to become a cornerstone in the fight against AMR, offering a forward-looking approach to safeguarding the efficacy of antibiotics for future generations.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"35 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144581965","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}

The x-ray diffraction (XRD) pattern shows an average particle size of 26.29 nm, and the diffraction results match the standard database values for JCPDS No. 073–1701. The SEM micrographs confirmed the presence of NPs with fine, flower-like morphologies which aggregated as clusters. The EDAX spectra confirm the presence of Co and O in the percentages of 46.91% and 53.09%, respectively, which is close to the theoretical ratio (3:4) for Co₃O₄. The TEM images revealed an enlargement of diffraction rings composed of several diffraction spots, indicating the polycrystalline nature of Co₃O₄. The NPs’ average size was found to be approximately 87 nm. The energy band gap value of Co₃O₄ NPs is 1.64 eV. The Fast Orange dye's photodegradation rate was found to be 79% in the presence of Co₃O₄ NPs under ultraviolet (UV) light irradiation. The highest recorded zones of inhibition for calcined Co₃O₄ NPs against <i>Bacillus cereus</i> and <i>Escherichia coli</i> were 16.8 and 15.9 mm, respectively. The prepared NPs also exhibited excellent sensitivity towards alcohol detection using cyclic voltammetry with the 0.1 N HCl as a electrolyte.

Saline wastewater is generated by industries such as desalination plants, food processing, textile and dyeing, pharmaceuticals, and metal processing industries. Currently, these wastewaters are treated in plants where they are evaporated to generate salt wastes, incurring high transportation, handling, and process costs that burden industries and disrupt their profitability. Consequently, industries are seeking alternative, economically viable treatment methods. <i>Dunaliella salina</i>, a halophilic algae, presents a promising solution. It can reduce nutrient concentrations in wastewater and produce industrially relevant compounds such as carotenoids, lipids, and proteins.

This study aims to evaluate the seasonal hydrogeochemical variations in the Mor River basin, assess the associated health risks, and determine the groundwater quality for domestic suitability. The research addresses the gap in studies examining the combined effects of agricultural practices, seasonal variations, and health risks on groundwater quality in this region. A total of 68 groundwater samples were collected during the pre-monsoon (PRM) and post-monsoon (POM) seasons of 2022. Major ions were analyzed following American Public Health Association (APHA) standards, and the results were compared with World Health Organization (WHO) 2017 drinking water standards. The analysis revealed that parameters such as electrical conductivity (EC), pH, total dissolved solids (TDS), total hardness (TH), magnesium (Mg), calcium (Ca), bicarbonate (HCO₃), chloride (Cl), nitrate (NO₃), and fluoride (F) exceeded the desirable (DL) and permissible limits (PL) in both seasons. Elevated TDS (average 1350 mg/L) and TH (average 320 mg/L) in PRM indicated mineral leaching and the influence of irrigation. Notably, 79% of the samples in PRM and 38% in POM exceeded the WHO-recommended nitrate limits, suggesting the impact of agricultural practices. Groundwater Quality Index (GWQI) values ranged from 117.38 to 188.87 (average 150.46) in PRM and 97.08 to 181.29 (average 133.54) in POM, indicating poor water quality. Health risk (hazard quotient [HQ]) values exceeded safe limits, particularly for teenagers and adults, with non-carcinogenic hazards identified in both seasons. The findings highlight the significant degradation of groundwater quality due to intensive irrigation and fertilizer use, which adversely affects human health.
