TLDR
The results showed that paraxanthine, caffeine and acetaminophen were the main individual pollutants usually found in concentrations over 20 ppb, and the hydroxyl radical reaction was the major pathway for the oxidative transformation of these compounds.About:

Journal ArticleDOI
Occurrence and ecological risk of pharmaceutical and personal care products in surface water of the Dongting Lake, China-during rainstorm period
Yongqiang Wang,Ying Liu,Shaoyong Lu,Xiaohui Liu,Yuan Meng,Guodong Zhang,Yaru Zhang,Weiliang Wang,Xiaochun Guo +8 more
TL;DR: The risk quotient (RQ) method was used to evaluate ecological environment risk under the worst case and the results suggested that clarithromycin, diclofenac, roxithromyzin, and erythromycin might pose a significant risk to aquatic organisms in Dongting Lake, especially clarithromecin.

Factors that have an effect on degradation of diclofenac in aqueous solution by gamma ray irradiation.
Qun Liu,Xingzhang Luo,Zheng Zheng,Binguo Zheng,Jibiao Zhang,Yongjun Zhao,Xiaoying Yang,Jiaqi Wang,Lianhong Wang +8 more
TL;DR: The degradation efficiency of diclofenac decreases with the increase of its initial concentration and is higher under acidic conditions than in neutral and alkaline media, and it is proposed that transformation pathways are initiated mainly by H·, eaq−, and ·OH.
Journal ArticleDOI
Biodegradability of fluoxetine, mefenamic acid, and metoprolol using different microbial consortiums
TL;DR: The values of kbiol for fluoxetine, mefenamic acid, and metoprolol determined with the three consortiums indicated that ammonium-nitrite-oxidizing and heterotrophic biomass allow a partial biodegradation of the compounds, while no substantial biodegrades can be expected using nitrite- oxidizing consortium.

Optimized electro-Fenton process with sacrificial stainless steel anode for degradation/mineralization of ciprofloxacin
Mostafa Shoorangiz,Mohammad Reza Nikoo,Marjan Salari,Gholam Reza Rakhshandehroo,Mojtaba Sadegh +4 more
TL;DR: In this article, an electro-Fenton process with auto generation of Fenton's catalyst (Fe2+) was proposed and its applicability in degradation and mineralization of Ciprofloxacin (CIP) antibiotic was examined.
Journal ArticleDOI
Impact of tetracycline on the performance and abundance of functional bacteria of a lab-scale anaerobic-aerobic wastewater treatment system.
TL;DR: In this article, a lab-scale anaerobic-aerobic system was established to evaluate the impacts of 5'mg'l−1 tetracycline on the performance of a labscale wastewater treatment system and the abundance of related functional bacteria.

Occurrence, fate and effects of pharmaceutical substances in the environment- A review
Bent Halling-Sørensen,S. Nors Nielsen,P.F. Lanzky,Flemming Ingerslev,Hans-Christian Holten Lützhøft,S.E. Jørgensen +5 more
TL;DR: Present knowledge does not reveal if regular therapeutic use may be the source of a substance carried by sewage effluent into the aquatic system, even though clofibrate, a lipid lowering agent, has been identified in ground and tap water samples from Berlin.
Journal ArticleDOI
Occurrence of drugs in German sewage treatment plants and rivers
TL;DR: In this article, the occurrence of 32 drug residues belonging to different medicinal classes like antiphlogistics, lipid regulators, psychiatric drugs, antiepileptic drugs, betablockers and β 2 -sympathomimetics as well as five metabolites has been investigated in German municipal sewage treatment plant (STP) discharges, river and stream waters.

A review of imperative technologies for wastewater treatment I: oxidation technologies at ambient conditions
TL;DR: In this article, the authors highlight five different oxidation processes operating at ambient conditions viz. cavitation, photocatalytic oxidation, Fenton's chemistry, ozonation, and use of hydrogen peroxide.
Journal ArticleDOI
Oxidation of pharmaceuticals during ozonation and advanced oxidation processes
TL;DR: It could be shown that the second-order rate constants determined in pure aqueous solution could be applied to predict the behavior of pharmaceuticals dissolved in natural waters.
