TL;DR: A global-scale analysis of the presence of 203 pharmaceuticals across 41 countries is presented and it is shown that contamination is extensive due to widespread consumption and subsequent disposal to rivers.

TL;DR: In this article, the impact of veterinary medicines on the environment will depend on a number of factors including physicochemical properties, amount used and method of administration, treatment type and dose, animal husbandry practices, manure storage and handling practices, metabolism within the animal, and degradation rates in manure and slurry.

TL;DR: An assessment of currently available models for predicting concentrations of veterinary medicines entering surface waters indicated that for sulfachloropyridazine, the methods provide reasonable estimates, predicted concentrations being within a factor of two of the maximum measured concentrations.

TL;DR: It is shown that prevalence of class 1 integrons is higher in bacteria exposed to detergents and/or antibiotic residues, specifically in sewage sludge and pig slurry compared with agricultural soils to which these waste products are amended.

TL;DR: It is evident that processes governing pesticide fate also apply to veterinary antibiotics, while preferential flow via desiccation cracks and worm channels to the tile drains was found to be the most important route for translocation of the chemicals.
