Monitoring of 17 β-Estradiol Residues in the Suez Canal Region

This study was initiated to provide the first recor d of monitoring of 17 �- estradiol (E2) residues in some Egyptian aquatic ec osystems. Samples of water were collected from three water bodies located in the Su ez Canal region. Samples were extracted, filtered and examined by HPLC on a C 18 column using Florescence detectors. Results provided evidence of the presence of estra diol in the studied area. Interestingly, marine lakes contained significant l evels of 17 �-estradiol (P
