Sobhi A. Helal
I am a professor of Stratigraphy and Paleontology in fayoum University. I am interested in Micropaleontology, Paleoecology, Paleoclimatology and Paleoenvironmental interpretations. Recent ostracoda and Foraminifera, their distribution and environmental relations is also a part of my experience.

manganese, zinc, copper, nickel, cadmium, lead, and cobalt in recent sediment samples
of Safaga Bay, Egypt. Concentration of heavy metals in sediments shows significant
variability and ranges from 863.37 to 1144.93 ppm for Fe, 64.29–586.8 ppm
for Mn, 2.7–12.68 ppm for Zn, 3.01–7.2 ppm for Pb, 1.53–3.29 ppm for Ni,
0.55–1.57 ppm for Co, 0.16–1.37 ppm for Cu, and 0.22–0.4 ppm for Cd.
Sediment pollution assessments were carried out using an enrichment factor and
geoaccumulation index. The calculation of enrichment factor showed that Cd is enriched
by 4.1 due to phosphate sources in Safaga Bay. The Geoaccumulation index results
revealed that there are positive and negative correlations between Fe, Zn, Mn, Pb, Ni,
Cu, Co, and Cd indicating that these metals have complicated geochemical behaviors.
