The aim of this study was to determine the fate of Pseudomonas aeruginosa \"opportunistic bacteria \" in Al Kabeer Al Shamali River and its correlation with drinking water quality (pH, Electrical conductivity, Turbidity, NO3-, NO2-, NH4+ and PO4-3) in three locations; lake inlet \" Ghammam Bridge \", artificial (the 16th Tishreen Dam Lake, and the outlet Ain al-Bayda irrigation tunnel).  during the period 2018-2019 and 2019-2020. The membrane filtration technique was used to detect Ps. Aeruginosa. Results showed significant differences (p<0.05) between sites for Ps. Aeruginosa, EC, Tur and NO3- . The highest counts for Ps. aeruginosa recorded in Ghammam Bridge water reaching 290000 cfu/100 mL ​​in Jun and correlated with NH4+ (r =0.72).  Then counts decreased to 420 cfu/100 ml in May in 16 Tishreen Dam Lake water, due to stratification and environmental stresses. Ps. Aeruginosa counts were higher in lake outlet than 16th Dam Lake and reached 53000 cfu/ 100 ml in July, May due to the release from sediments. Canadian Water Quality Index CCME WQI showed that the lake inlet water is moderate class C (64). The waters of 16th Dam Lake and the outlet are of good grade II B due to sedimentation.

Heavy metals directly influence human being lives since they concentrate in the food cycle, even in low amounts. Some heavy metals pollute the water resources, in dangerous limits for human life. The current study suggested the cement kiln dust (CKD) as a low-cost and effective adsorbent to remove heavy metals ions from solutions. Therefore, the study investigated the copper, lead and cadmium removal from aqueous solution by cement kiln dust (CKD) as industrial by-product. The laboratory experiment included two factors. The first factor consists of three different diameter particles i.e., 50,100, and 150 . While the second factor included three concentrations of each of copper, cadmium, and lead ions namely 50,100, and 200 mg. l-1. The cement kiln dust was identified by X-ray diffraction analysis (XRD) to determine its chemical characteristics. Also, pH and EC were measured for the cement kiln dust solution. Before the study starting, the initial concentration of the copper, cadmium, and lead were measured in the CKD power. The study was conducted at temperature of 25 . The removal efficiency was calculated at two different time of shaking, namely 1 and 2 hours. The obtained results indicated that CKD can be used as a low cost and effective sorbent for copper, cadmium, and lead ions from polluted water. Moreover, the results show that the high pH and high surface area for the cement kiln dust have the main effect of making the CKD efficient adsorbent material.","PeriodicalId":126839,"journal":{"name":"Journal of Life Science and Applied Research","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115451279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
