TL;DR: Findings indicate that several conventional wastewater management practices are not effective in the complete removal of antibiotics, and their discharges have a large potential to affect the aquatic environment.

TL;DR: This method for the determination of cocaine, amphetamines, morphine, cannabinoids, methadone, and some of their metabolites in wastewater could be useful to estimate and monitor drug consumption in the population in real time, helping social scientists and authorities to combat drug abuse.
Abstract: Residues of illicit drugs and their metabolites that are excreted by humans may flow into and through wastewater treatment plants. The aim of this study was to develop a method for the determination of cocaine, amphetamines, morphine, cannabinoids, methadone, and some of their metabolites in wastewater. Composite 24-h samples from urban treatment plants were enriched with deuterated internal standards before solid-phase extraction. High-pressure liquid chromatography tandem mass spectrometry with multiple reaction monitoring was used for quantitation. Recoveries were generally higher than 80%, and limits of quantifications were in the low nanograms-per-liter range for untreated and treated wastewater. The overall variability of the method was lower than 10% for untreated and 5% for treated wastewater. The method was applied to wastewater samples coming from two treatment plants in Italy and Switzerland. Quantification ranges were found to be 0.2−1 μg/L for cocaine and its metabolite benzoylecgonine, 80−20...

TL;DR: In this article, a review of electrochemical and bio-electrochemical technologies for the removal of protein rich wastes from aquaculture ponds and hatcheries is presented, which can remove contaminants at high efficiencies (≈99%) whilst giving least impact upon the environment.
