“…2). Salinity is considered as a sensitive parameter for measuring the rate of dilution of seawater caused by land-based source discharge and subsequently, it reflects the degree of contamination in aquatic environment (Zyadah et al, 2004). Salinity at Sidikerir region showed a narrow seasonal variation (Fig.…”

A hot spot region of the Mediterranean Sea located at Sidikerir west of Alexandria was chosen to evaluate the present status of its water quality due to the direct impacts of effect of the power station, petroleum pipe company (SUMED) and some tourist villages. Subsurface and near bottom water samples were collected seasonally during 2012 at eight locations to measure physicochemical and nutrient salts characteristics as indicators of the water quality.Temporal, spatial fluctuations as well as statistical correlations between the analyzed variables were examined. They demonstrated a wide range of water temperature (17.14-26.31°C), narrow fluctuations in salinity (37.51-39.71), and well-oxygenated seawaters (4.16-8.00 mg O 2 /l), low amounts of oxidizable organic matter (1.92 mg O 2 /l) and the seawater was slightly alkaline (pH range 8.03-8.53). Nutrient characteristics sustained the levels up to 1.68, 11.00, 8.82, 1.15 and 33.18 lM for reactive phosphates, reactive silicates, ammonium, nitrite and nitrate, respectively. Total nitrogen and total phosphorous were fluctuated between 17.63-118.65 and 0.20-2.80 lM, respectively. Trophic states, as well as factors affecting the water quality of study area, were evaluated. The water quality index WQI demonstrated that Sidikerir water was between medium and good.

“…[21] recorded pH-values of water at Abu-Quir site as (7.57 -8.26). They added that the decrease in pH-value is coincided with the drop in oxygen content due to the effect of discharge of brackish water whereas, [22] reported that the values of hydrogen-ion concentration pH showed high concentration at the Eastern section of coast Mediterranean sea. The increase and decrease of pH values may be due to the mixed drainage water at the represented sites [23].…”

“…He recorded the pH-value in the El-Mex Bay as 8.06, whereas Abu-Quir Bay recorded pH-value as 7.76. pH concentration may be highly significant factor in determining or limiting the threshold concentration. [22] reported that dissolved oxygen is considered as one of the most important and useful parameters in identification of different water masses and in assessing the degree of pollution. The maximum value of DO can be attributed to lower water temperature as well as strong winds [22].…”

The present study attempted to test the applicability of using phytoplankton as a bioindicator for assessing water quality along the Eastern Alexandria coast, Egypt. Eight stations were selected to cover the different characteristics of seawater during the summer 2022. Six algal groups were detected in different ratios: Bacillariophyceae, Cyanophyceae, Dinophyceae, Chlorophyceae, Silicoflagellata, and Euglenophyceae. Phytoplankton abundance was found highest at the Port Said (PS) beach, and the lowest abundance was detected at Ras El Bar (RB) beach. According to the evaluation of phytoplankton abundance, all the studied stations are oligotrophic state except PS was eutrophic. Based on Chl a concentration, the selected stations could be described as good-bad from west to east. The Shannon diversity and Pielou evenness indexes classified the studied stations as being moderate pollution except for PS and RB stations. The existence of organic pollution indicators species like Navicula, Synedra, and Euglena is a warning indication of the declining water quality especially in B and M stations. The biochemical compositions of the collected phytoplankton were spatial fluctuated. Protein and carbohydrates were the dominant macromolecules in the phytoplankton community compared with lipids. These macromolecules are used to assess trophic states whereas the ratio between protein and carbohydrate > 1 represents a healthy coast as observed in some stations. Thus, phytoplankton should be considered a bioindicator within Water Framework Directive monitoring programs for the Mediterranean Sea. For the long-term monitoring of the Mediterranean Sea’s ecosystem, it is recommended that the macromolecules of phytoplankton should be determined.
