Pharmaceuticals are polluting the waterways of our world. A study funded by a $150,000 grant from the EPA found fish carrying detectable levels of pharmaceuticals in their bodies. The research, conducted by Baylor University researcher Bryan Brooks, and published in Environmental Toxicology and Chemistry, examined fish caught near Phoenix, Dallas, Chicago, Philadelphia and Orlando, testing them for residues of pharmaceuticals. Brooks found the fish to be contaminated with:
- Seven different pharmaceuticals, including cholesterol drugs, blood pressure drugs, allergy drugs and psychiatric medications used to treat bipolar disorder and depression
- Two different chemicals used as artificial fragrance in soaps
The trace chemicals were found in fish near all of the sites tested bar one: in order to establish a baseline reference of healthy, non-contaminated fish, researchers caught fish in the Gila River Wilderness Area of New Mexico, which is far from any cities or developments.
It seems to be quite clear from this research that pharmaceuticals have become a widespread source of chemical pollution that has permeated delicate aquatic ecosystems and now poses yet another threat serious threat to our environment.
