Pharmaceutical products when disposed off into the environment causes a variety of ecosystem and human health effects. The management of pharmaceuticals containing wastewater is extremely important. Traditionally, common pharmaceuticals-laden wastewaters treatment includes biological treatment processes, membrane technology, advanced or a combination of these. Ionizing technology for the removal of pharmaceuticals in wastewater is technically feasible. Several studies have elucidated the degradation pathways of several antibiotics in aqueous solutions. Hydroxylation, desulfonation, ring cleavage, and ultimately fragmentation and mineralization are the key mechanisms involved for example in sulfonamide degradation. Toxicity and antibacterial inhibition studies of the treated wastewaters are important to rule out any undesirable toxicity or residual antibacterial activity of the breakdown products. Scavengers that could impair the efficiency of ionizing technology are also a strong possibility in wastewater. A major advantage of using ionizing technology for pharmaceutical wastewater management is that no additional chemical additives are needed.}, year = {2022}, pages = {229-241} } @article{MTMT:32632511, title = {Matrix effect in the hydroxyl radical induced degradation of ß-lactam and tetracycline type antibiotics}, url = {https://m2.mtmt.hu/api/publication/32632511}, author = {Wojnárovits, László and Wang, JL and Chu, LB and Tóth, Tünde and Kovács, Krisztina and Bezsenyi, Anikó and Szabó, László and Homlok, Renáta and Takács, Erzsébet}, doi = {10.1016/j.radphyschem.2022.109980}, journal-iso = {RADIAT PHYS CHEM}, journal = {RADIATION PHYSICS AND CHEMISTRY: THE JOURNAL FOR RADIATION PHYSICS RADIATION CHEMISTRY AND RADIATION PROCESSING}, volume = {193}, unique-id = {32632511}, issn = {0969-806X}, abstract = {Due to the spread of antibiotic resistant bacteria, elimination of antibiotics from purified wastewater is a highly important task. Purified wastewater contains large variety of organic/inorganic compounds that strongly influence the efficiency of advanced oxidation processes (AOP). In this work, we investigate the radiation-induced degradation of selected antibiotic contaminants (oxacillin and cloxacillin from the beta-lactams; tetracycline and chlortetracycline from the tetracyclines) in four matrices: pure water, tap water, synthetic wastewater and purified wastewater received from a wastewater treatment plant. Changes in technically important parameters, such as COD, TOC, BOD, OUR, acute toxicity and antibacterial activity, were investigated at 0.1 mmol dm(-3) (40-48 mg dm(-3)) antibiotic concentration. None of the four antibiotics were biodegradable in any of the four matrices, however, after irradiation with relatively low doses the obtained products were biodegradable. Oxacillin and cloxacillin were not toxic in Vibrio fischeri test, while tetracycline and chlortetracycline showed toxicity that was strongly reduced by the irradiation treatment. Both COD and TOC decreased after irradiation, their ratio shifted towards TOC indicating an increase in the average oxidation state (AOS). The increase in AOS was lower in purified wastewater matrices: this matrix may contain various small, highly oxidized molecules in high concentration, which degrade very slowly in AOP. The antibacterial activity in most of matrices was greatly reduced or completely disappeared at around 2-4 kGy. However, in purified wastewater matrices some antibiotic activity remained even at 4 kGy. Here the degradation of antibiotic is slow (small delta COD/dose value) because a large fraction of the reactive radicals is scavenged presumably by small, highly oxidized molecules in the solution. Although the water radiolysis product H2O2 affected some of the bioassays, this phenomenon was absent in purified wastewater. The purified wastewater after ionizing radiation treatment can be safely released into the receiving lakes or rivers.}, keywords = {MOLECULES; AQUEOUS-SOLUTIONS; Elimination; TOXICITY; Chemistry, Physical; HYDROGEN-PEROXIDE; WASTE-WATER; Penicillins; radiolysis; ADVANCED OXIDATION PROCESSES; TiO2 photocatalysis; oxygen uptake rate; Nuclear Science & Technology; BOD; Irradiation treatment; Average oxidation state}, year = {2022}, eissn = {1879-0895} } @article{MTMT:32126916, title = {Elimination of oxacillin, its toxicity and antibacterial activity by using ionizing radiation}, url = {https://m2.mtmt.hu/api/publication/32126916}, author = {Takács, Erzsébet and Wang, J. and Chu, L. and Tóth, Tünde and Kovács, Krisztina and Bezsenyi, Anikó and Szabó, László and Homlok, Renáta and Wojnárovits, László}, doi = {10.1016/j.chemosphere.2021.131467}, journal-iso = {CHEMOSPHERE}, journal = {CHEMOSPHERE}, volume = {286}, unique-id = {32126916}, issn = {0045-6535}, year = {2022}, eissn = {1879-1298} }
