“…Salinity can affect chemical reactions in water. It can influence the solubility and availability of various compounds, including nitrates [23]. Changes in salinity may impact the rates of chemical reactions involving nitrates, leading to variations in nitrate concentrations.…”

“…Changes in salinity may impact the rates of chemical reactions involving nitrates, leading to variations in nitrate concentrations. In similar hydrodynamic conditions in the Persian Gulf, the water quality status of Sharjah lagoons was assessed by Cavalcante, et al (2021) [23] using specific water quality properties such as chlorophyll and nutrients. The measurements were obtained during both spring and neap tide periods in January 2020.…”

“…The correlation analysis between nutrients and salinity in the Persian Gulf lagoons revealed that in Al-Khan lagoon, there was a correlation between internal mixing and nutrient levels, particularly for nitrite during spring tide and phosphate during neap tide conditions. However, in Khalid lagoon, no significant correlation was found between nutrients and salinity, suggesting that other factors might be influencing nutrient loads [23]. [23] noted a significant rise in dissolved oxygen (DO) levels, increasing from 8.1 mg/l (S3) to 10.7 mg/l (S4) during neap tide.…”

[23] noted a significant rise in dissolved oxygen (DO) levels, increasing from 8.1 mg/l (S3) to 10.7 mg/l (S4) during neap tide. This increase is likely due to the improved solubility of oxygen resulting from a decrease in temperature and salinity.…”

The coastal wetland, Ballona Lagoon in Southern California has experienced degradation and size reduction due to urbanization. This study analyzes nitrate concentrations in the lagoon to identify contamination sources and assess its impact. The study includes determining nitrate levels during high and low tides during wet and dry seasons, establishing concentration gradients, and examining the relationship between salinity and nitrate concentrations. The nitrate concentrations were found to be higher in locations closer to the head of the lagoon, particularly in urbanized areas, suggesting land-based sources during the dry season's high tide (S2: 2.37 mg/l; S3: 3.85 mg/l; S4: 3.91 mg/l). Findings highlight the importance of managing nitrate contamination near urban areas. Monitoring nitrate levels over time are crucial for sustainability efforts. This research emphasizes the need for long-term monitoring and conservation strategies to mitigate nitrate contamination in Ballona Lagoon.

This paper presents potential upgrades to the Palm Jumeirah Island’s outer revetment to extend its design life for 50 years, considering the sea level rise (SLR) associated with climate change. The paper proposes several upgrade options to ensure that the hydraulic stability and wave overtopping discharges of the Palm Jumeirah revetment comply with the recommended design criteria based on industry guidelines. The performance of the existing revetment, in terms of the hydraulic stability and wave overtopping discharge criteria, is assessed using design wave heights (1- and 100-year events) extracted from an extreme wave analysis study on the Dubai coast. The results show that, based on the new design conditions, the existing structure should be upgraded to meet the armor stability criteria and recommended overtopping discharge values. Three different upgrade solutions are designed and analyzed to satisfy the required hydraulic stability and overtopping conditions. The suggested upgrade options are an extra armor layer, a flat berm, and a submerged breakwater offshore. The proposed upgrade solutions are preliminary designs that would require verification in terms of their geotechnical stability and physical model testing to evaluate their performance.

Background: The objective of this work was to propose the treatment of the wastewater from Laguna da Jansen using adsorptive processes of residues of pineapple crown and shrimp chitosan. Methods: Residual substrates were distributed in 11 Erlenmeyers, and 250 mL of residual pond water were added; the solution was incubated under agitation at the times and amounts established by the Experimental Design (DCCR). After this period, analyses of pH, electrical conductivity, turbidity, nitrate, and nitrite, morphological analyses by SEM, and structural analyses by FTIR and XRD were performed. Results: The FTIR and SEM results showed that the biomass presented active chemical groups and a morphology rich in pores. The experimental design showed that the substrate content was the variable that influenced the lagoon effluent treatments for both tested biomasses; however, when observing the specific values of the response variables, the vegetable adsorbent was more efficient with the conditions of 15g of substrate and 30 days of process. Conclusion: Plant biomass is more efficient in the treatment of effluents rich in organic materials. It can be used in treatment plants as an alternative for the removal of toxic compounds present in wastewater and effluents.
