Prof. Gehan Mohamed El Zokm



She is a professor at the marine chemistry department and leader of the halogen, sulfide modeling, and surfactant groups at the National Institute of Oceanography and Fisheries, Mediterranean Sea Branch in Egypt. She got her B.Sc., M.Sc., and Ph.D. in the Chemistry Department at the Faculty of Science of Alexandria University in Alexandria, both of which concerned heavy metal chemistry (focusing on preconcentration and fractionation tools). She is a professor of environmental chemistry in the marine chemistry lab at the Marine Environment Division. Her research interests are in analytical and instrumental chemistry. Statistical analyses were the most prominent features of her research, which was conducted using the most recent software packages. Her papers discuss the topics of halogen chemistry, water quality, sulfur and sulfide chemistry, eutrophication, and the responses of marine biota to pollutants. Her study also focuses on the mobility and fluxes of various parameters within marine environmental components. Extraction of natural products with many applications and nutritional studies are her recent projects. Her research is also focused on water treatment and monitoring of pollutants (heavy metals, nutrients, phenols, hydrocarbons, and pesticides). She has 56 research papers and three books with an h-index of 18. She applied factorial design to water treatment experiments. She is interested in the ecotoxicity of surfactants on Egyptian coasts.
