It is not known though if an assessment has been carried out by a `qualified limnologist'!

In addition, no studies were conducted to assess the downstream impacts as a result of endocrine disruptors. The EDCs of concern in this are bisphenol A (BPA), and ethinyl estradiol (EE2), because of their environmental relevance and frequent human exposure. All three have been found in streams throughout the United States, England, and Japan. Also, each compound is relevant in terms of human exposure.

"Considerable evidence exists that aquatic organisms are being exposed to, and impacted by, a wide range of compounds that mimic hormones. Fish exposed to these compounds often exhibit an array of responses including depressed circulating sex steroid levels, reduced gonad size and fecundity, and males have become feminized. One of the most sensitive and common tools used to assess exposure to endocrine disrupting chemicals (EDCs) with estrogenic activity is the presence of vitellogenin (VTG), an egg yolk protein precursor, in the plasma of male fish. Recent studies have shown elevated plasma VTG in male fish downstream of sewage treatment plants." (ELA-DFO)

The jpeg scan of the underwater picture was extracted by biologist, Peter Shacklock, from the Tv show we had produced featuring underwater video of the fish species of the Shubenacadie Lake system during year-1994.
