[CEST2019_00375] Identification of biotransformation products of veterinary drugs present in piggery wastewater during treatment with photobioreactors based on microalgae-bacteria and purple phototrophic bacteria consortia
by López-Serna R., García D., Bolado S., Jiménez J.J., Lai F.Y., Golovko O., Ahrens L., Wiberg K., Gago-Ferrero P., Muñoz R.

This work identified transformation products (TPs) from 16 antibiotics, 1 anti-parasitic, 1 analgesic and 1 hormone, present in spiked real piggery wastewater (PWW) before and after two different treatments in two open photobioreactors operated continuously with a consortium of microalgae-bacteria and purple photosynthetic bacteria. For this purpose, suspect and non-target strategies based on liquid chromatography quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS) were used.

[CEST2019_00130] Mass balance of selected pharmaceuticals in an Austrian river catchment area: estimation of the different source contributions
by Ghirardini A., Verlicchi P., Zoboli O., Zessner M.

The study refers to the assessment of the annual mass loadings of two pharmaceuticals (PhCs), sulfamethoxazole (SMX) and carbamazepine (CBZ), released in the river of an Austrian catchment area by wastewater treatment plant (WWTP) effluent, combined sewage overflows (CSOs), surface runoff, tile drainage and deep water (referring to the sludge- or manure-amended soil).

[CEST2019_00143] Adsorption technology in waste water treatment processes utilizing activated carbons as adsorbent materials prepared from waste vehicular tires: Recent research and trends in the removal of various toxic and persistent organic and inorganic pollutants
by Vagi M.C., Petsas A.S.

Various toxic contaminants when are present in the environment pose a threat to the inhabitants of natural ecosystems owing to their non-biodegradable nature that increases their high toxicity towards non-target organisms. The large mass of solid wastes that are generated from waste rubber tires unquestionably consists a serious threat of environmental pollution around the world.

[CEST2019_00157] The pyrolysis of perfluorocarboxylic acids - effect of chain length
by Dixon L., Weber N., Stockenhuber S., Molloy S., Lucas J., Grimison C., Stockenhuber M., Mackie J., Kennedy E.

Per- and polyfluoroalkyl substance (PFAS) are increasingly becoming the contamination issue of our time, due to their environmental persistence, bioaccumulation and mounting evidence of their toxicity. Herein we examined the pyrolytic decomposition of a series of perfluorocarboxylic acids via the production of CO and CO2, utilizing FTIR and GC/MS analysis.
We observed the presence of a parallel surface-mediated reaction in conjunction with the gas-phase pyrolysis.
