概括

环境噪音污染对鸟类健康有重大影响. 研究表明,噪音压力会增加皮质和甲状腺刺激激素 (TSH),同时降低诸如黄素化激素 (LH) 和卵泡刺激激素 (FSH) 等生殖激素,也会导致羽毛损伤.

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
