The present work aimed to measure the concentration of Cd, Cu, Pb, Mn, and Zn in the soft tissues of Ruditapes decussatus which collected between December 2018 and February 2019 from two sites of Mediterranean Sea. One from Alexandrian Port (Site I) and the other from Port Said (Site II), Egypt, as well as to estimate the potential physiological change of the clam affected by these pollutants. Samples from Site I gives comparatively higher water salinity and metals concentration in soft tissues. The statistical analysis shows significant increase in the level of malondialdehyde (MDA) while superoxide dismutase (SOD) and glutathione peroxidase were found decreased in the R. decussatus soft tissue collected from Site I. The correlation coefficient of physicochemical parameters, heavy metals and oxidative stress biomarkers in Site I shows that glutathione peroxidase and superoxide dismutase have positive correlation with acetylcholinesterase (r=0.912) and (r=0.929), respectively. SOD, on the other hand, was having negative correlation with MDA (r= -0.886). The reported values in this study are considered as basic data in monitor of the anthropogenic activities in future along the coast, as well as it is starter point in assessment of pollution that maybe effect on the aquatic organisms in the Mediterranean marine environment.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"57 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89757026","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}

A composite sample was collected from diary industry plant at New Damietta City on March 2018 and characterized for some physicochemical parameters to check the pollution potential of the effluents. Due to the high content of total suspended solids, chemical coagulation/precipitation process using lime, alum/lime and alum/polyacrylamide was applied for pretreatment of the collected sample and the optimum conditions were determined. Moreover, chemical coagulation using alum/lime followed by AOPs with Fenton’s reagent was also assessed. The results showed that the concentration of COD is 112000 mg/L while for BOD is 78000 mg/L. In addition, the removal percentage of oil and grease, COD, total phosphorous (TP) and total Khejdal (TKN) by Fenton’s reaction after treatment with alum-lime are 86, 85, 99.35 and 99.03 %, respectively compared with that achieved by alum-lime (86.82, 73.11, 91.8 and 54.93 %, respectively).

Samples were collected from ten sites representing different habitats of the lagoon, from summer 2017 to spring 2018. The water properties were determined; noticeable low concentrations of dissolved inorganic nutrients were recorded. A total of 106 species belonging to six groups were recorded, among them Bacillariophyta (69 species) and Dinophyta (26 species). The obtained results clarify that Bacillariophytes prevailed in the eastern sites of Bardawil; on the contrary, Dinophytes occupied the sovereignty in the western sites of the lagoon. The most abundant Bacillariophytes were Licmophora gracilis, Gyrosigma acuminatum, Fragilaria construens, and Nitzschia sigmoidea; which formed more than 50% of total abounded diatoms. While, Protoperidinium leonis, Prorocentrum gracile and Protoperidinium granii were the dominant Dinophytes, giving it maximum at El-Rewak. From reviewing previous studies on the lagoon, it becomes clear that the phytoplankton composition varied widely from previously recorded, including the dominant species and their rates of sovereignty, which reflected economically on its fish productivity. Besides, the water quality in Bardawil fluctuated from slightly-polluted to moderately-polluted according to the diversity index, as a result of the recent, noticeable increase in human activities, especially fishing, which will be in turn reflected in the environment. Therefore, continuous follow-up through ecological assessment and monitoring studies of Bardawil became an urgent necessity.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"33 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81549941","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}

However, to determine how much control O2 has on the variability in VOC concentration, Regression Analysis was used. The result shows VOC concentration and O2 to have negative correlations of 0.7134, 0.0058, 0.4558, 0.4105, 0.8162, 0.0982 in boreholes A, C, E, G, I, K respectively. This analysis shows O2 to be the dominant control on the variability in and therefore emission of VOC concentration two (A and I) of the six monitored boreholes in this site. Being the only borehole with the highest negative R2 value, borehole I was reanalysed and the R2 considered over different periods of rising and falling limb O2 with the result showing that O2 was the dominant control on VOC concentrations during 90% of the entire monitoring period. The dominant controls in the variability of VOC concentration in the remaining boreholes need be determined. This is because, understanding their controls will help to predict how VOC concentration will change in future. Also, given that VOC can be dangerous even at trace concentrations; this site is recommended for remediation.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"11 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89528958","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}
