Ecological Quality Status of Marine Environment: Metal- Sulfide Models; Significance, Mobility, Mechanisms and Impacts

Dr. Gehan El Zokm 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 earned 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 specialist in environmental chemistry in the Marine Environment Division. Her research interests are in analytical and instrumental analytical chemistry with an emphasis on fractionation techniques (metals, sulfur, phosphorus, and nitrogen) regarding their bioavailability. Sulfide-metal dynamic models' topic has been a great concern in her publications. Statistical analyses were the most prominent features of her research, which was conducted using the most recent software packages. Her papers discussthe topics of eutrophication and pollution as well as the responses of marine biota to these two phenomena. Her study focuses on the mobility and fluxes of various parameters within marine environmental compartments. Her recent projects include natural product extraction for a variety of applications as well as method characterization (FTIR, XRD, SEM, TEM, EDEX, GC, HPLC, UV-Vis, and BET). Nutritional and functional food studies are highlighted in her research. Her research is also focused on water treatment and the mobility as well as fluxes of pollutants (heavy metals, phenol, hydrocarbons, and pesticides). She has 50 research papers and two books with an H-index of 17. A factorial design is applied for water treatment experiments. She reviews a lot of papers for many important publishers (Elsevier, Springer, and Taylor & Francis). She supervised and headed several projects and postgraduate students, participated in many conferences and workshops, and has several activities.

Dr. Gehan El Zokm是埃及地中海分部國家海洋學和漁業研究所海洋化學系的教授，也是卤素、硫化物建模和表面活性劑研究小組的負責人。她在亞歷山大大學理學院化學系獲得學士、碩士和博士學位，研究重金屬化學（專注於預濃縮和分離工具）。她是海洋環境部門的環境化學專家。她的研究興趣在於分析和儀器分析化學，重點是關於生物可利用性的分離技術（金屬、硫、磷和氮）。硫化物-金屬動態模型一直是她研究的重點之一。統計分析是她研究的最突出特點，使用最新的軟件包進行研究。她的論文討論了富養化和污染以及海洋生物對這兩個現象的反應。她的研究重點是海洋環境組分內各種參數的遷移和通量。她最近的項目包括天然產物提取用於各種應用以及方法表徵（FTIR，XRD，SEM，TEM，EDEX，GC，HPLC，UV-Vis和BET）。營養和功能性食品研究是她研究的重點。她的研究還聚焦於水處理以及污染物（重金屬，酚，烴類和農藥）的遷移和通量。她有50篇研究論文和兩本書，H指數為17。她在水處理實驗中應用了因子設計。她為許多重要出版商（Elsevier，Springer和Taylor＆Francis）審查了許多論文。她監督和領導了多個項目和研究生學生，參加了許多會議和研討會，並有多個活動。
