In the last two decades research has found that environmental chemicals can interrupt the endocrine system and generate reproductive abnormalities in wildlife, such as vitellogenin induction, feminized reproductive organs, reduced fecundity, changes in sex ratio, and developmental degeneration. These compounds are called environmental hormones, which are part of the emerging compounds. Within the field of endocrine disruption, estrogenic effects are currently the greatest concern. A number of endocrine disrupting chemicals (EDCs) found in aquatic environments has the potential to interfere with estrogenic functioning. Of greatest concern are the natural estrogenic steroid hormones: 17β-estradiol (E2), estrone (E1), and estriol (E3) and the synthetic estrogenic steroid hormones 17α-ethynylestradiol (EE2) and diethylstilbestrol (DES). |
