TLDR
Potential aerobic biodegradation mechanisms of the widely used polar, low-adsorptive sulfonamide antibiotic sulfamethoxazole (SMX) were investigated in activated sludge at bench scale and enhanced when a readily degradable energy supply was provided which fostered metabolic activity.About:

A critical review on antibiotics and hormones in swine wastewater: Water pollution problems and control approaches
Dongle Cheng,Huu Hao Ngo,Wenshan Guo,Soon Woong Chang,Dinh Duc Nguyen,Yiwen Liu,Qin Wei,Dong Wei +7 more
TL;DR: The development of antibiotic alternatives and the enhanced implementation of vaccination and biosecurity are promising management approaches to cut down the consumption of antibiotics during swine production and the combined system of bioprocesses and AOPs is expected to be a promising technology for elimination and mineralization of A&H in swine wastewater.

Oxidation of sulfamethoxazole (SMX) by chlorine, ozone and permanganate—A comparative study
TL;DR: It was shown that different oxidants shared some common pathways, such as the cleavage of SN bond, the hydroxylation of the benzene ring, etc, but each of the oxidants also exhibited exclusive degradation mechanisms, leading to the formation of different transformation products (TPs).

Occurrence, fate, and removal of pharmaceutical residues in the aquatic environment: a review of recent research data
TL;DR: Several PhACs from various prescription classes have been found at concentrations up to the microg/l-level in sewage influent and effluent samples and also in several surface waters located downstream from municipal sewage treatment plants (STPs).
Journal ArticleDOI
Ecotoxicology of human pharmaceuticals.
TL;DR: It is shown that only very little is known about long-term effects of pharmaceuticals to aquatic organisms, in particular with respect to biological targets, and targeted ecotoxicological studies are needed focusing on subtle environmental effects.
Journal ArticleDOI
Occurrence of antibiotics in the aquatic environment.
TL;DR: From the large number of ground water samples that were taken from agricultural areas in Germany, no contamination by antibiotics was detected except for two sites, which indicates that intake from veterinary applications to the aquatic environment is of minor importance.
