The application of equipment and tools that produce a magnetic field is increasing in aquatic ecosystems. In the present study, the effects of acute (1 week) and subacute (3 weeks) exposures to different static magnetic fields (SMFs) of 2.5, 5, 7.5 mT on stress indices (cortisol and glucose), sex steroid hormones (17β-estradiol and 17-α hydroxy progesterone) and fecundity of the zebrafish (Danio rerio) were investigated. The obtained results showed a significant change in cortisol, glucose, 17β-estradiol (E) and 17-α hydroxy progesterone (17-OHP) levels by enhancing the intensity and time of exposure to SMFs. In conclusion, the SMFs, especially at higher levels of intensities, showed physiologically harmful effects on the reproductive biology of the zebrafish during acute and subacute exposures.
在水生生态系统中，产生磁场的设备和工具的应用正在增加。在本研究中，研究了斑马鱼（Danio rerio）急性（1周）和亚急性（3周）暴露于2.5、5、7.5 mT不同静磁场（SMF）对压力指标（皮质醇和葡萄糖）、性类固醇激素（17β-雌二醇和17-α羟基孕酮）以及繁殖力的影响。获得的结果表明，通过增加暴露于SMF的强度和时间，皮质醇、葡萄糖、17β-雌二醇（E）和17-α羟基孕酮（17-OHP）水平发生了显著变化。总之，SMF，尤其是在较高强度水平下，在急性和亚急性暴露期间对斑马鱼的生殖生物学表现出生理有害影响。
