“…The results obtained in this study showed that during the summer due to high temperatures and eexcessive microbial activities resulting in decline of nutrients in rivers [21]. Similar results have also been reported from studies on water pollution in Diyala River in Iraq [22], Al-Diwaniyah River in iraq [23] and the Euphrates River [24]in Iraq. In a study conducted by Sasakova et al, report the presence of microbial contamination eastern Slovakia: The results of microbiological tests revealed a significant increase in the numbers of all bacterial groups identified in the warmer seasons, except for the winter ssampling [25].…”

Background: Surface water bodies are essential sources of water for human consumption, residential use, agriculture, industrial operations, as well as for aquatic life and ecosystems. Materials and Methods: Water samples were collected from 4 sites of the Al-Warar water system, west of Ramadi, during the summer and winter seasons from October 2022 until July 2023; bacteriological and physicochemical parameters were analyzed for water samples also isolation and identification of bacteria. Results: Ranged values of Temperture, pH, turbidity, Chloride, TDS, Sodium, EC, TH, sulphate, DO, BOD, nitrite, nitrate, phosphate, and FC during winter season and summer were 12°C, 7.2-7.6, 5.5-10.5 NTU, 167-274 (mg L-1) 975-1331 (mg L-1), 140-208 (mg L-1), 1453-1996 (μS/cm), 129-155(mg L-1), 388-597(mg L-1), 4-8 (mg L-1), 8.5-15.5(mg L-1), 1-3 (mg L-1), 2.80-10.70(mg L-1), 0.05-0.14(mg L-1), and 3.19-5.83 (colony per ml), respectively. The corresponding values during the summer season were 33°C, 7.6-7.8, 6-12NTU, 232-288 (mg L-1), 1062-1518 (mg L-1), 165-225 (mg L-1), 1960-2705 (μS/cm), 127-145 (mg L-1), 416-686 (mg L-1), 5.8-7.9 (mg L-1), 9-14 (mg L-1), 0.35-1.70 (mg L-1), 0.66-0.81 (mg L-1), 0.14-1.27 (mg L-1), and 5.10-14.11 (colony per ml), respectively. The highest rate of coliform bacteria was recorded throughout the study period in the summer, and the lowest rate was recorded during the winter, where (5) species of the Enterobacteriaceae family were diagnosed with different percentages: Escherichia coli 37% and then Klebsiella pneumonia at 25%. Enterobacter closes at a rate of 15%, then Enterobacter ludwigii at a rate of 13%, then Aeromonas veronica at a rate of 10%. Escherichia coli bacteria also dominated all study sites, indicating microbial contamination of Al-Warar water system.

Luminescent Ln-MOFs (Eu0.075Tb0.925-MOF) were successfully synthesised through the solvothermal reaction of Tb(NO3)3·6H2O, Eu(NO3)3·6H2O, and the ligand pyromellitic acid. The product was characterised by X-ray diffraction (XRD), TG analysis, EM, X-ray photoelectron spectroscopy (XPS), and luminescence properties, and results show that the synthesised material Eu0.075Tb0.925-MOF has a selective ratio-based fluorescence response to Fe3+ or Cr2O72−. On the basis of the internal filtering effect, the fluorescence detection experiment shows that as the concentration of Fe3+ or Cr2O72− increases, the intensity of the characteristic emission peak at 544 nm of Tb3+ decreases, and the intensity of the characteristic emission peak at 653 nm of Eu3+ increases in Eu0.075Tb0.925-MOF. The fluorescence intensity ratio (I653/I544) has a good linear relationship with the target concentration. The detection linear range for Fe3+ or Cr2O72− is 10–100 μM/L, and the detection limits are 2.71 × 10−7 and 8.72 × 10−7 M, respectively. Compared with the sensor material with a single fluorescence emission, the synthesised material has a higher anti-interference ability. The synthesised Eu0.075Tb0.925-MOF can be used as a highly selective and recyclable sensing material for Fe3+ or Cr2O72−. This material should be an excellent candidate for multifunctional sensors.
