Tracking opioids in the environment
As opioid use continues to proliferate, the drugs enter more people's bodies, where they break down into metabolites often other opioids that end up in wastewater. Scientists have detected opioids downstream of wastewater treatment plants and are concerned about the potent drugs possible effects on organisms who live in those waters.
