Flocculation is influenced by several factors, including salinity, suspended sediment concentration, and mixing processes. In natural systems, these variables are constantly changing, making it difficult to study flocculation in a controlled manner. To overcome this challenge, laboratory mixing tanks have been developed that allow researchers to manage environmental conditions to mimic what happens in the real world. The combined investigation of these influencing factors on the population density of flocs in the hypothetical river estuary will provide a deeper understanding of this phenomenon and can provide insights into the behavior of flocs in the river estuary. To replicate conditions close to reality, the lab mixing tank should be operated under conditions that mimic the natural mixing processes that occur in the estuary. By conducting experimental tests under controlled laboratory conditions and employing image processing techniques, this study contributes to the scientific understanding of floc population dynamics in estuaries. Statistical results show that the minimum population density of flocs will be created at the concentration of suspended sediments equal to 150 and 200 mg/L and the probability of formation of flocs with lower population density is 66%, also the volume of saline water in lower volumes with a percentage of 55%, the probability of formation of flocs with less population density is higher. On the other hand, the maximum population density of the flocs will be created in larger amounts of saline water volume and the probability of formation of flocs with higher population density is 55%.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 6","pages":"4689 - 4706"},"PeriodicalIF":3.0,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to assess, for the first time, the influence of temperature fluctuations on azoxystrobin photodegradation kinetics in loam soil. High-performance liquid chromatography was utilized to analyze dissipation rates under sunlight and dark conditions, with a quantitation limit of 0.05 mg/kg. Sampling intervals of 0, 1, 7, 15, 21, and 28 days were employed during incubation. Azoxystrobin dissipation rates were determined using first-order kinetic modeling. Results indicate a significantly accelerated dissipation rate under sunlight conditions (0.2018/day, t ½ = 3.4 days) compared to darkness (0.0912/day, t ½ = 7.6 days), highlighting the substantial impact of photodegradation and temperature fluctuations.

In the context of Iran’s Houmand Absard, where groundwater is the primary source of freshwater, this approach has proven particularly effective. Initially, 86 pragmatic indicators were identified, and a global survey of 155 researchers, combined with fuzzy analysis, reduced these to 27 critical indicators. Notably, environmental indicators emerged as the most significant, with the 'percentage of aquifer area with groundwater overexploitation problem' receiving the highest score of 0.750.

These elements prevent the treatment of these effluents, for which all the treatments applied failed to meet the discharge standards. On the other hand, fly ash from thermal power plants is a severe environmental issue worldwide. The valorization of these wastes may be the best strategy to protect our environment. In this respect, the primary purpose of this work is to emphasize a promising technique for OMW treatment, using filtration through fly ash. A physical–chemical and microbiological characterization of the OMW was carried out beforehand. Then, the treatment was performed in the fixed-bed column adsorption process using fly ash as an adsorbent. This characterization revealed that the OMW have an acidic pH and is abundant in organic matter, as illustrated by the BOD<sub>5</sub> (20,650 mg O<sub>2</sub>/L) and COD (99,864 mg O<sub>2</sub>/L). They are equally characterized by a high concentration of phenolic compounds (6452 mg/L). Microbiological characterization revealed a total absence of pathogenic and fecal germs. The treatment of OMW by fly-ash filtration provided outstanding results as illustrated by the abatement rates obtained, which were 100%, 99.77%, 99.63%, and 99.96%, respectively for discoloration, BOD<sub>5</sub>, COD, and polyphenols. In addition, the treated effluent perfectly fulfilled the Moroccan rejection standard. The fly ash support has shown a purifying performance for all toxic loads. Therefore, fly ash filtration could be an appealing and cost-effective technique for the treatment of both highly loaded and poisonous wastewater. Furthermore, fly ash could replace activated carbon in water treatment plants.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 6","pages":"4511 - 4520"},"PeriodicalIF":3.0,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study showed that approximately 91 percent of the region experienced a significant temperature increase, with an average rise of about 1.32°C over 39 years (1979–2017). This indicates that the warming trend in this region is greater than the total warming of the Earth, and almost half of the region experienced temperature increases ranging from 1 to 2°C.

SDMs along with variables associated with vegetation, precipitation, temperature, and soil characteristics were used to investigate the distribution of <i>S. infraimmaculata</i>. Models were converted into binary based on a baseline threshold to extract suitable conditions for Protected areas (PAs). Landscape metrics including Class Area, Number of Patches, Mean Shape Index, Edge Density, Mean Nearest Neighbor Distance, and Mean Patch Size were employed to assess habitat patches within the PAs. Additionally, we conducted a multi-scale analysis of fragmentation across the landscape, using the foreground area density (FAD) method to identify potential AC areas. Results confirmed model effectiveness in accurately identifying suitable conditions. Soil organic carbon (SOC), precipitation, and temperature emerged as the primary drivers influencing the species' distribution. Shaho and Kusalan, Boozin and Marakhil emerged as the most extensive potential habitat area. The highest number of patches was observed in the Bisotun complex, while the most sizable patch area was concentrated in Shaho and Kusalan.
