Intermittent exposure of fish to estradiol

Article Abstract:

Researchers from AstraZeneca Ltd. and Brunel University, UK, investigated the effects of fluctuating levels of estradiol exposure to male fathead minnows. Results reveal that intermittent exposure to the contaminant evokes a higher response and change in plasma vitellogenin concentration and gonad weight than when exposed continuously.

Assessing the biological potency of binary mixtures of environmental estrogens using vitellogenin induction in juvenile rainbow trout (Oncorhynchus mykiss)

Article Abstract:

Three-month-old female rainbow trout obtained from Cornwall and Dorset in the United Kingdom are exposed to estrogenic chemicals E2, NP, and MXC. Concentrations of plasma vitellogenin (VTG) are measured following exposure, and graphed compared to pre-exposure levels.
