Abstract

This study was initiated to provide the first record of monitoring of 17 β- estradiol (E2) residues in some Egyptian aquatic ecosystems. Samples of water were collected from three water bodies located in the Suez Canal region. Samples were
extracted, filtered and examined by HPLC on a C18 column using Florescence detectors. Results provided evidence of the presence of estradiol in the studied area. Interestingly, marine lakes contained significant levels of 17 β-estradiol (P <0.05). Lower levels were also detected in the rivlet streams supplied by River Nile.
Detection of estradiol in the aquatic ecosystems of the Suez Canal region grabs the attention towards the heavy reliance on some esterogenic medicinal products in the area, and the eventual effect on the aquatic systems including biodiversity of a variety of organisms. Therefore, it is recommended to enlarge the detection scanning of estradiol in other Egyptian areas.
