Journal ArticleDOI
Screening of Human Antibiotic Substances and Determination of Weekly Mass Flows in Five Sewage Treatment Plants in Sweden
TL;DR: Analysis of the weekly mass flows through each STP showed that FQs were partly eliminated from the water during sewage water treatment and the highest amounts of these substances were found in sludge, indicating that they too can withstand sewageWater treatment.
Journal ArticleDOI
Determination of antibiotic substances in hospital sewage water using solid phase extraction and liquid chromatography/mass spectrometry and group analogue internal standards.
TL;DR: Analogue internal standards for fluoroquinolones, sulfonamides, trimethoprim, beta-lactams, nitroimidazoles and tetracyclines were successfully used for calibration and shown to generally improve precision compared to external calibration.
Journal ArticleDOI
Behavior of fluoroquinolones and trimethoprim during mechanical, chemical, and active sludge treatment of sewage water and digestion of sludge.
Richard H. Lindberg,Ulrika Olofsson,Per Rendahl,Magnus Johansson,Mats Tysklind,Barbro Andersson +5 more
TL;DR: The results suggest that fluoroquinolones undergo thermal degradation during pelleting, but more studies are needed to confirm this.
Journal ArticleDOI
Environmental risk assessment of antibiotics in the Swedish environment with emphasis on sewage treatment plants.
Richard H. Lindberg,Karin Björklund,Per Rendahl,Magnus Johansson,Mats Tysklind,Barbro Andersson +5 more
TL;DR: In leaching tests less than 1% of the amounts of these fluoroquinolones in the sludge or pellets reached the aqueous phase, indicating that their mobility is limited if sludge is used to fertilize soil.
Journal ArticleDOI
Fluoroquinolone antibiotics in a hospital sewage line; occurrence, distribution and impact on bacterial resistance
Per-Åke Jarnheimer,Jakob Ottoson,Richard H. Lindberg,Thor Axel Stenström,Magnus Johansson,Mats Tysklind,Mari-mall Winner,Bjorn R. Olsen +7 more
TL;DR: The focus in this study was on fluoroquinolones, a widely used group of antibiotics with increasing resistance problems, and found low levels of ciprofloxacin and ofloxacins in waste water but high concentrations in sediment.
