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.”
