" Adult zebrafish were exposed to 4 h of RF-EMR daily from a 4G Wi-Fi router over a 30-day period. The exposed adult fish were bred under exposure free condition, on the 10th, 20th and 30th day of experiment. Fertilized embryos obtained from these breeding events were maintained under EMF-free conditions and were observed up to 10 dpf [days post fecundation: developed larvae] and analysed for developmental and neurobehavioral changes. After completion of the exposure on the 30th day, the adult male and female gonads were processed for histomorphological study. Histopathological analysis revealed significant testicular abnormalities, including seminiferous tubule disintegration, reduced spermatids, and abnormal lumina. Ovaries showed notable follicular degeneration and stromal disruption. Significant rates of mortality and gross morphological abnormalities like yolk sac edema, pericardial edema, curved axis and tail deformities were found in the progeny of exposed fish. Malformation rates increased significantly with longer adult exposure periods. Neurobehavioral tests on these larvae at 10 dpf showed anxiety-like behavior. The results indicated progressive decline in reproductive health of adults and increased adversities in the progeny." |
