TL;DR: A methodology for quantification of 40 antibiotics of 5 different classes, in river water, by SPE-LC-MS/MS was validated and revealed the presence of ARGs in all samples, with the highest concentration found for blaTEM.

TL;DR: In this paper, the authors evaluated the Fenton process in the removal of eight pharmaceuticals (gemfibrozil, nimesulide, furosemide, paracetamol, propranolol, dipyrone, fluoxetine, and diazepam) from three different water matrixes (distilled water, simulated wastewater, and hospital wastewater).

TL;DR: H2O2 and chlorine UV-based treatments were carried out to evaluate their efficiency in the removal of the bisphenol A, 17β-estradiol (E2) and 17α-ethinylest radiol (EE2) at 100 μg L-1 from ultrapure water and from wastewater treatment plants (WWTP).

TL;DR: An efficient, sensitive, and reliable analytical method for trace analysis of 17 different pyrethroids and chlorpyrifos in the fatty content of animal products, including beef, chicken, eggs, fish, and milk is developed.

TL;DR: Microorganisms isolated from “Lagoa do Peixe” National Park, a site with a history of frequent petroleum spills in Brazil, were shown to produce biosurfactants such as surfactins, iturins, mono- and di-rhamnolipids, which showed emulsifying activity of the cell-free supernatant at the end of the incubation time, with potential application in petroleum spills bioremediation.
