In the news: Study confirms persistent pharmaceutical pollution in nation's rivers

Studies continue to show the presence and persistence of pharmaceuticals and other personal care products in waterways throughout the country. And improperly disposed-of medicines have been shown to have numerous detrimental effects on plants, animals, and environmental processes. 

A forthcoming paper in Ecological Applications confirms the presence of pharmaceuticals in rivers throughout the U.S. 

From Nature World News
"As it turns out, the antihistamine diphenhydramine - used in treating allergic symptoms as well as motion sickness, insomnia and a cold - decreased a biofilm's photosynthesis by 99 percent in addition to drops in respiration. And it didn't stop there. The chemical compound actually caused a change in present bacterial species, including a reduction of a group that digests compounds produced by plants and algae.

Nor was it the only one tested to render similar results; in fact, all the pharmaceuticals involved in the study had a measurable and negative impact on biofilm respiration."
