TL;DR: In this article, HPLC-UV high-resolution mass spectrometry was used to analyze the degradation products formed during ozonation of an aqueous solution of the antibiotic ciprofloxacin in a bubble column.

TL;DR: This paper presents the development and application of a new multi-residue analytical method providing the first data on the environmental occurrence of human pharmaceuticals in Africa, particularly the Nairobi River basin (Kenya), and is the first study that provides evidence of detection of lamivudine in surface water.

TL;DR: Liquid chromatography - high resolution mass spectrometry revealed degradation at the piperazinyl substituent and the quinolone moiety, with the relative importance of both pathways being strongly affected by changes in pH.

TL;DR: The ozonation of ciprofloxacin was studied in hospital wastewater treatment plant effluent with focus on parent compound degradation, degradation product identification and residual antibacterial activity and revealed strong pH dependence.

TL;DR: Through systematic research a novel analytical method using solid-phase extraction (SPE) and liquid chromatography magnetic sector mass spectrometry was developed for the measurement of 43 pharmaceuticals in wastewater, which indicated to be of high potential environmental risk for the receiving river Dender, Belgium.
