Researchers exposed minnows to a blend of linuron, an herbicide used to control grasses and weeds, and DEHP, a plasticizer used to make medical products.

Minnesota researchers have found endocrine disruptors in nearly every lake they’ve tested.

Environmental experts said the discoveries in lakes, rivers and streams increase the pressure on Wisconsin to figure out what’s in its water. A key Wisconsin Department of Natural Resources official said that the state’s waters were likely also contaminated, but that the state had no money for such monitoring.

Advice from experts on how to limit your exposure and your impact on the environment.

“It’s hard not to make people too worried about a lot of things,” said UW-Madison pediatric endocrinologist Ellen Connor, after running through a plethora of hypothesized health effects — genital abnormalities, tumors, lower sperm counts, diabetes, early puberty — and an equally long list of worrisome chemicals.

The four groups of chemicals that trigger consumption advisories — PCBs, mercury, dioxins and PFOS (perfluorooctane sulfate) — have all been associated with endocrine disruption.
