Research Abstract

Aquatic environmental pollution by pharmaceuticals has been emerging as a worldwide problem. Many chemicals have been detected at ng/L - ug /L levels in the environment. In this study, we analyzed several pharmaceuticals and their metabolites in hospital sewage by using liquid chromatography ion electrospray ionization tandem mass spectrometry (LC/MS/MS). We detected some pharmaceuticals, acetaminophen (antipyretic), chlorhexidine. (antiseptic) and levofloxacin (antibiotic). The contents in the sewage varied among individual samples. The sewage samples showed toxicity in the Daphnia magna mortality test, Daphnia magna reproduction test and Microtox^<【O!R】> test with P. phosphoreum. Hospital sewage might be having a significant impact on the ecosystem.
