Characterization and environmental impact assessment of gold mine tailings in arid regions: a case study of Barramiya gold mine area, Eastern Desert, Egypt.
Geochemical and mineralogical characterization and environmental impact assessment were performed on Barramiya gold mine tailings, Eastern Desert, Egypt. The Barramiya gold mine is situated within ophiolite decorated Nugrus suture zone, which composed of dismembered sequence of highly deformed and metamorphosed mafic to ultramafic rocks and their hydrothermal alteration products (carbonate rocks), interbedded with meta-volcano clastic rocks of the Nubian Shield. ... إقراء المزيد

Impact of wastewater disposal on groundwater contamination by nitrate and ammonium, Sohg, Upper Egypt
Contamination by nitrate was found in all samples (from wells and pumps). As many as 80%of the water samples contain nitrate concentration exceeding the 45 mg l -1 standard for safedrinking water recommended by the United States Environmental Protection Agency (EPA). Eight of the examined ten samples display NO - 3 ranging from 57-120 mg l -1 . The nitratecontents ... إقراء المزيد

2018-09-11 20:56:14 الكلمات المفتاحية PCR, Contamination, Tissue Culture, Mycoplasma,
One of the main problems in cell culture unit is mycoplasma contamination. It can extensively affect cell physiology and metabolism. As the applications of cell culture increase in research, industrial production, cell therapy and its importance for diagnostic routine work in selected labs, so more concerns about mycoplasma contamination will arise. In our study, a total of 50 cell cultures ... إقراء المزيد

The investigation of pathogenic fungi in poultry feed in some selected poultry farms in Sohag Governorate, Egypt
Mould occurrence and growth in poultry farms is one of the major threats to poultry economy and health. The aim of this study was to investigate the mycological contamination of poultry feeds used in poultry farms in Sohag Governorate, Egypt. A total of 160 samples of poultry feed were collected from 10 farms for mycological analysis. The isolated fungi from ... إقراء المزيد

Flood hazard assessment and heavy metal distributions around Um Gheig mine area, Eastern Desert, Egypt
This study focuses on wadi Um Gheig and its associated Pb-Zn mine to quantify the possible dispersion pathways of heavy metals to the surrounding environment. The morphometric drainage system parameters were specified by ArcGIS 9.3. A total of 21 samples were collected and analyzed using XRF, XRD, ICP-OES and SEM. Different enrichment indices were applied to specify the degree and ... إقراء المزيد

Application of MLA in reactive transport modeling of weathering processes in intensely stratified tailings
Reactive transport simulations have been applied to investigate possible effects of stratification on the potential of sulfide-bearing mine tailings to form protective cemented layers and to retain toxic elements. Our research is based on a German tailings site, which material is intensely stratified on a mm-cm scale. Multiple cemented layers have been observed in the oxidized part of the tailings, ... إقراء المزيد
