The investigated parameters of the Water Quality Index (WQI) are temperature, pH, salinity, dissolved oxygen (DO), DO saturation, oxidizable organic matter (OOM), suspended particulate matter (SPM), Chl-a, ammonium, nitrite, nitrate, total nitrogen, reactive phosphate, total phosphorus, silicate, Zn, Fe, Mn Cu, Cd, Pb, and Ni. The results revealed that the pH values were slightly alkaline with a range of 7.85-8.20. The results of other parameters were as follow salinity (36.95-42.61PSU), DO (5.22-6.67 mg/L), OOM (0.40-1.23 mg/L), SPM (12.39-21.5 mg/L), Chl-a (0.10-0.83 µg/L). The range of nutrients (μM) were 0.07-0.22, 0.45-1.47, 9.62-18.64, 23.31-57.65, 0.05-0.15, 0.55-2.78 and 2.54-5.51 for NH4/N, NO2/N, NO3/N, TN, PO4/P, TP and SiO4/Si, respectively. Cluster analysis was used to classify the stations studied. From the current study, five clusters were found, indicating the need to perform cluster analysis in the water quality assessment process to confirm the durability and consistency of the data discovered in the current application.Propolis (bee glue) is a bee glue, sticky resinous material released from various plant sources such as bud exudates, flowers, and leaves modified by bee secretions and wax propolis is composed of resins, waxes, polyphenols, polysaccharides, volatile materials, and secondary metabolites that are responsible for various bioactivity such as antibacterial, anti-angiogenic, antiulcer, anti-inflammatory, antioxidant, and anti-viral activities. The physico-chemical characteristics and the natural properties of various kinds of propolis have been studied for the past decade. Novel active anti-microbial compounds have been identified in propolis. Those compounds positively modulated th
