Study finds steroids may persist longer in the environment than expected

themselves, to as much as 60 percent of the metabolite's initial mass, when tracked over a 120-hour period.

"We knew something unique was going on," Cwiertny says. "In daylight, it essentially hides in another form, to evade analysis and detection, and then at nighttime it readily grows back."

More of the drug's mass was regenerated up to 88 percent in one highly acidic state (pH 2) when water temperature was higher and when it was more acidic or alkaline, the team found.

The researchers validated the lab results with two experiments in the field one with water culled from the Iowa River in Iowa City, Iowa and the other from samples taken from a collection pond at a cattle rangeland and research operation run by the University of California.
