In 2001, scientists began adding 5 to 6 nanograms per litre of synthetic estrogen to an Ontario lake; after 2 seasons its minnow population collapsed
- Representative Image (AI-generated)A tiny concentration of a synthetic hormone was enough to trigger a dramatic ecological change in a remote Ontario lake.
- In 2001, scientists began adding the synthetic estrogen 17α-ethynylestradiol (EE2) to Lake 260 in northwestern Ontario, maintaining concentrations of about 5 to 6 nanograms per litre.
- The experiment continued for seven years, including three years of estrogen additions and two years of observations after they stopped.
