Effects of ibuprofen on Rainbow Trout (Oncorhynchus mykiss) following acute and chronic waterborne exposures
Pharmaceuticals and personal care products are a growing concern in the aquatic environment. Compounds from the class of non-steroidal anti-inflammatory drugs are commonly detected in surface waters and have the potential to negatively affect aquatic organisms. The purpose of this experiment was to …
