“…According to integrated pollution indices, PLI, C deg , NIPI, and PERI were implemented. The PLI was used to evaluate the extent of metal contamination of sediments in various locations (Soliman et al, 2022 ). The overall and integrated index of PLI illustrated that Eastern Harbour, Abu Qir, Abu Khashaba, Burullus, Baltim, Gamasa, and Bardawil Lake inlet west are below and at the baseline levels.…”

“…The exceeding of limited metal values in water resources poses a severe environmental concern (Tepe et al, 2022 ; Thabet et al, 2023 ). Metals are considered hazardous contaminants due to their environmental persistence, biomagnifications, and cumulative behavior as well as their potential adverse effects (Madruga et al, 2014 ; Soliman et al, 2022 ; Ustaoğlu et al, 2020 ). Metal pollution in aquatic environments is caused by a variety of sources, including agricultural runoff, mining and industrial effluents, and domestic sewage (Ali et al, 2019 ; Nour et al, 2022 ; Thabet et al, 2020 ).…”

The surface sediments from eleven sectors perpendicular to the Egyptian Mediterranean Sea coast, along the delta region, have been assessed. These sectors cover areas of Eastern Harbour, Abu Qir Bay, Rosetta, Abo Khashaba, Burullus, Baltim, Damietta, and Manzala. The assessment process is based on determining the eight metals’ (Fe, Cu, Zn, Mn, Ni, Co, Pb, and Cd) content, followed by applying different pollution and ecological risk indices such as enrichment factor (EF), geoaccumulation factor (Igeo), contamination factor (CF), Pollution Load Index (PLI), degree of contamination (Cdeg.), Nemerow Integrated Pollution Index (NIPI), and Potential Ecological Risk Index (PERI). The results indicate the average concentrations of metals (μg/g) were Fe (18,000), Mn (213), Zn (120), Ni (26), Co (13), Cu (12), Pb (10), and Cd (2). The single-pollution indices reveal that most metals were depleted to metal levels, the sediments were moderately polluted with Cd and unpolluted with other metals, and the CF values confirmed that the sediments were highly polluted with Cd and low contaminated with the rest of the metals. According to the integrated pollution indices, the Eastern Harbour, Damietta, Manzalah, and Bardawil (eastern Inlet) are the most polluted sectors relative to the rest, subjected to various point sources of pollution. Drainage management system is recommended to enhance water conservation and improve fish stocks.

“…Statistically constructed experiments are chosen for error reduction, parameter analysis, and low-cost data acquisition. In general, the one-variable at a time (OVAT) method is not challenging, however it has a limited ability to accurately predict the effects of interacting factors and may cause misinterpretation of the outcomes (Abd El-Hamid, AlProl & Hafiz, 2022; Soliman et al, 2022). There are a variety of optimization and modeling methodologies available, starting with the simple one factorial at a time (OFAT) model and progressing to composite and nexus statistical designs such as response surface methodology (RSM) (Abd El-Hamid, AlProl & Hafiz, 2022).…”

Response surface methodology (RSM) and Box-Behnken (BB) statistical experiment design were developed to study the optimization of oily wastewater treatment using Sargassum latifolium. The characterization of the Sargassum latifolium was studied using fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), N 2 adsorption/ desorption, and Raman techniques. These studies demonstrated the importance of various functional groups such as carbonyl, amino, carboxyl, and hydroxyl on adsorption mechanism. The specific surface area of S. latifolium was 111.65m 2 / g. Scanning electron microscope (SEM) showed that the interaction of S. latifolium with oil led to the development of flakelike deposits on its surface, causing the surface to become uneven. Four process-independent parameters, including contact time, oil volume, adsorbent dosage, and pH were optimized for the best response of crude oil adsorption using Box-Behnken design. The output was summarized for an additional ANOVA analysis. Optimization conditions for crude oil adsorption onto Sargassum Latifolium were found to be at an adsorbent dose of 0.13g, oil volume of 24.29ml, time of 57.44 minutes, and initial pH of 9.54. Langmuir and Freundlich isotherm models were used to apply equilibrium analysis. The results suggest that the Langmuir model better fits the experimental data compared to the Freundlich model. The experimental results showed that the crude oil adsorption capacity onto Sargassum latifolium was 45.87gm under ideal conditions, which was somewhat lower than the RSM model's value of 46.14gm.
