Center for Environmental Studies and Advocacy: It’s Turning Point from Vision to Action

Myrna Nicol Ogoc, Rolando A. Delorino and Atty. Franco Archie N. Tonog,[DOI: 10.24214/jecet.A.8.2.15109]

Environmental degradation is human civilization’s adverse impact on the planet. Rising to the fore is a string of environmental problems that threaten man’s very existence and hence cannot be underestimated.  All the living systems whether on land or sea surrounding us are being ruthlessly exploited.  This senseless attack on the natural world rapidly hits at the very base of our living world and endangers its usefulness for future generations. The damage on the natural resources is irreversible yet needs to be addressed with urgency if only to contain and arrest their continuous degeneration in order to ensure their availability into the future. Environmental protection and sustainability are imperative educational goals anchored on the recognition of our important role in reversing the course of our failing environment.  Our capacity to destroy comes with our ability to restore.The academe as the source of all legitimate information and learning plays a critical role in the development of individuals into responsible citizens imbued with a heightened sense of environmental consciousness and ethics actualized by routine.  It can adequately provide opportunities to learn about the dynamics of nature and how to care for it and to conserve   finite natural resources.  In addition, the academe can institutionalize the adoption of sound techniques for the protection and conservation of ecological balance through ecological management techniques and building community capacity for leadership and participation. Environmental concern is a value that needs to be channeled into every individual within the academic fold.  

Commercial Fish Catch as an Index of Lakes Eutrophication in Egypt

Maiyza, Sh. I. and El-Caryony, I. A ; [DOI: 10.24214/jecet.A.8.1.11022]

The study is an attempt to identify the location of Egyptian Northern Mediterranean Delta Lakes in relation to Vollenweider classification of lakes from oligotrophy to polytrophy in the course of eutrophication process. Time series approach has been used to achieve the aim of the study and to predict future catches from these lakes.  It was found that Egyptian Northern Delta Lakes can be considered in the 5th stage of Vollenweider model

Gold, radioactive and associated mineralization in Gabal El-Maghara Coal, Sinai, Egypt: Mineralogy and geochemistry

Mohammed El Ahmady Ibrahim; Amira Mohammed El-Tohamy, and Marwa Medhat Abdel Azeem ,[DOI: 10.24214/jecet.A.8.1.08609.]

Gabal El-Maghara is located in North Sinai, Egypt. The exposed sedimentary succession is 200 m thick and consists of six formations. Economically, the Safa Formation (160–215 m thick) is the most important rock unit and contains more than 11 coal seams, two of which are minable; namely: The Main Coal Seam (MCS) and the Upper Coal Seam (UCS). The former is ~130 to 190 cm thick and has an estimated coal reserve of about 52 million tons. The Jurassic El- Maghara coal, contains a large mineral assemblage of uranium (betafite, plumbobetafite, kasolite and zippeite) and thorium (thorite and uranothorite) in addition to gold. Zircon, fluorite and barite were also recorded. These minerals are allogeneic (detrital) and, less commonly, authigenic. Allogeneic minerals were inherited from crystalline rocks in Sinai and especially older hydrothermal deposits that were formed at wide ranges of temperature and pressure. On the other hand, some base metals (pyrite, chalcopyrite, galena, nickel, zincite, scheelite and cuprite) in El- Maghara coal were formed authigenically by: (i) precipitation from circulating underground waters; and / or (ii) by the action of marine waters during periods of the post- Jurassic sea transgressions.  Gold (0.5 gm/ ton) was originally precipitated from mesothermal and epithermal solutions as a result of changes in physic-chemical conditions and fugacity of oxygen and sulfur. Based on the results of this study, it is recommended to evaluate the importance of El- Maghara coal as a resource of radioactive and some base metals. On the other hand, the coal mines have several negative environmental impacts as they represent a source of significant pollution. This requires taking serious steps to avoid or, at least, reduce this environmental hazard.  

Agrochemicals use on carrot (Daucus carota) cultivation and its phytochemicals content at Kedjom-Ketinguh, North- West, Cameroon

Sonchieu Jean, Feh Watad Gilbert, Fru Nsoh John,[DOI: 10.24214/jecet.A.8.1.07283]

Nationwide surveys conducted on pesticide application in Cameroon raised growing concern of the exposure of applicators. The aim of this study was to investigate the agricultural practices in carrot cultivation, phytochemical composition of carrot and the various exposures of farmers associated with the use of agrochemicals in the cultivation of carrot in Kedjom-Ketinguh, Tubah Sub-Division (North-West Region, Cameroon). A questionnaire was randomly administered to 100 carrot cultivation farmers for a period of twelve months. Laboratory analysis was done to determine the content of carrot with flavonoids, total carbohydrates and phenolic acid using spectrophotometric technics. The results obtained indicate that: 95% of the farmers use chemical fertilizers and organic manure (cow dung and fowls drops); 34% of farmers use fungicide such as pencozeb, mancozeb and plantineb, which are bought in local market or from individuals and stored in rooms in the house; the planting  is done in March at 50%, some minor health hazards associated with the use of agrochemicals were observed; the concentration of carbohydrates, flavonoids and phenols varies from the control to treated samples. The carrot produced in Kedjom-Ketinguh may be considered safe for consumption looking at the pesticide use and the quality is improved with the use of organic fertilizers.

Genetic link between HFSE - Base and Precious metals in Mylonite and N-S Lamprophyre Dikes, Abu Rusheid Area, Egypt

Mohamed El-Ahmady Ibrahim and Mohamed Salem Kamar,[DOI: 10.24214/jecet.A.8.1.05271.]

Abu Rusheid area is located at the southern Eastern Desert of Egypt and regarding as closed basin. The ophiolitic metagabbro forms the higher peripheral parts of the basin and thrusted over the ophiolitic mélange. The banded cataclastic rocks (NNW-SSE,300/WSW) were deposited in the central part of basin and subdivided from base to top into; protomylonites, mylonites , ultramylonites and quartzite. They are subjected to regional metamorphism (sillmanite- kaynite - garnet facies) and cut by two shear zones (N-S and E-W trends). The shear zones are intruded by discontinuous and brecciate lamprophyre dikes.The cataclastic rocks were subjected to hydrothermal alteration types, including propylitic, sericitic, Na-metasomatism, ferrugination, fluoritization, and argillation, whereas lamprophyre dikes were underwent ferrugination, kaolinitization, sericitization, and calcification. The mylonites and N-S lamprophyre dikes, are extremely rich in base metals (Pb, Zn, Cu, and As), precious metals (Au and Ag) and HFSE (Nb, U, Zr, HREE and Y). They show MREY > HREY > LREY. The HREEs minerals are represented by xenotime, fergusonite, fluorite and zircon. The average of U/Th ratio in mylonites and lamprophyre dikes (1.3 - 40.0) is higher than protomylonites and ultramylonites (0.24) manifesting migration in and out respectively. Ascending and descending hydrothermal solutions are affected on the Abu Rusheid rocks. These solutions with low temperatures and containing F1− and CO32−, PO43− and H2O caused redistribution; transportation and redeposition of the base metals, precious metals and HFSE from the mylonite rocks through channel ways to lamprophyre dikes, in addition to the clay minerals and carbonates were formed.
