Title: | Biodegradation of a mixture of benzophenone, benzophenone-3, caffeine and carbamazepine in a laboratory test filter | Authors: | Bogunović Minja Knežević Varja Simeunović Jelica Teodorović Ivana Ivančev-Tumbas Ivana |
Issue Date: | 2017 | Journal: | Journal of the Serbian Chemical Society | Abstract: | © 2017 SCS. The biodegradation of a mixture of four pharmaceutical and personal care products (PPCPs) (benzophenone (BP), benzophenone-3 (BP-3), caffeine (CF) and carbamazepine (CBZ)) was studied in a laboratory test filter. The column was filled with inert material to exclude the adsorption processes and to enable the development of the biofilm, while river water was recirculated. High removal for BP, BP-3 and CF was observed from the beginning of the experiment at the initial concentration of 20 μg L-1 (90-99 %). In the case of CBZ analytical difficulties were experienced. The efficacy of biodegradation reflected as a change of the overall toxicity of initial mixture of selected PPCPs vs. toxicity of samples which were undergone different biodegradation phases was assessed with two standard laboratory tests with apical endpoint - acute toxicity test with Daphnia magna (immobilisation) and bioluminescence inhibition with Vibrio fisheri. Toxicity tests showed the substantial reduction of the overall mixture toxicity in a laboratory test filter. The residual toxicity to D. magna might be attributed to undetected transformation products. | URI: | https://open.uns.ac.rs/handle/123456789/18067 | ISSN: | 0352-5139 | DOI: | 10.2298/JSC170717105B |
