Seven-day composite WwTW effluent samples were collected from both WwTWs (Figure 1) and analyzed for the steroid estrogens
17[beta]-estradiol, estrone, and 17[alpha]-ethinylestradiol and for the alkylphenolic compounds octylphenol, nonylphenol, and nonylphenol mono- and diethoxylates.
If this approach continues, we will never conquer the estrogen

What made this development possible was the discovery that the various natural estrogens
and synthetic estrogen
-like compounds do not all act in the same way and that whether a cell is affected or not by a particular type of estrogen
is not just a matter of yes or no.
These data demonstrate that environmental contaminants such as XEs of different classes (plastics manufacturing and detergent byproducts, pesticides, phytoestrogens, and synthetic estrogens
) can mimic endogenous estrogens
such as [E.
