TL;DR: Good fitted linear regression equations between antibiotic concentration and sediment physicochemical properties (TOC, texture and pH) were found, indicating that sediment properties are important factors influencing the distribution of antibiotics in the sediment of rivers.

TL;DR: Twenty-one antibiotics were found in the sewage sludge from the two WWTPs at the concentrations up to 5800ng/g, with tetracycline, oxytetracy Cline, norfloxacin and ofloxacIn being the predominant antibiotics.

TL;DR: This paper evaluated the excretion masses and environmental occurrence of 11 classes of 50 antibiotics in six typical swine and dairy cattle farms in southern China, suggesting that livestock farms could be an important pollution source of various antibiotics to the receiving environments.

TL;DR: A sensitive rapid resolution liquid chromatography-tandem mass spectrometry (RRLC-MS/MS) method, combined with solid-phase extraction, ultrasonic extraction and silica gel cartridge cleanup, was developed for 28 steroids and applied in the determination of the residual steroidal hormones in surface water, wastewater and sludge samples.

TL;DR: The results from this study clearly demonstrated the effectiveness of Fe(VI) treatment as a tertiary treatment technology for a broad spectrum of micropollutants in wastewater.
