Multiple Xenosteroid Pollutants Biomarker Changes in Xultured Nile Tilapia Using Wastewater Effluents as Their Primary Water Source.

ABSTRACT: This study was undertaken to screen levels of xenosteroids (estrogenic endocrine disrupting chemicals/E-EDCs) in Nile tilapia (Oreochromis niloticus) fish farms subjected to water fill from the drain at three sites S1 (highly polluted), S2 (moderately polluted), and a putative reference site (RS). Biometric, hormonal, gene expression, and histopathological analysis were investigated. Testosterone, progesterone, and zeranol residues were detected at (0.12-3.44 µg/L) in water samples of different sites. Bisphenol-A (BPA) exhibited a very high concentration (6.5 µg/mL) in water samples from S1. Testosterone, 17β-estradiol residues were detected in fish tissues from all sites at (0.16-3.8 µg/Kg) and (1.05-5.01 µg/Kg), respectively. BPA residues were detected at a very high concentration in the
