dc.description.abstractThe application of nanotechnology in textile products is progressively increasing as it is proving to be a useful tool in improving the performance of textiles. Titanium dioxide (TiO2) nanoparticles (NPs) have been the most studied ones to develop self-cleaning and anti-bacterial nano textiles. However, the adverse effects of NPs and the risk of the possible release of NPs into the wastewater process and then in receiving waters, thus ecotoxicity studies need to be performed for the safeguard of the environment. Monitoring oxygen uptake rate (OUR) has been demonstrated to be are a liable method to show any inhibition response of the activated sludge. Hence this study was performed to investigate the ecotoxicity and inhibition effects of NPs to Daphnia magna and activated sludge comparatively. Activated sludge inhibition tests were conducted to define the EC50 levels after 30 and 180 min of reaction time for TiO2 NPs, Ag-doped TiO2 NPs, and Cu-doped TiO2 NPs while Daphnia magna immobilization test was carried out for TiO2 NPs prepared by Degussa P25 and sol-gel method. The Ag-doped TiO2 NPs exhibited a toxic effect on the activated sludge 10 times higher than the TiO2 NPs.TiO2 NPs prepared by the sol-gel method caused 100% immobilization to Daphnia magna when exposed to 1 h settled sample after 48 h, and this severe toxicity repeated in the 2 h settled sample too. As a whole, the results obtained indicate that the technology should be accurately evaluated for the safety of the environment and human beings. © 2019 Desalination Publications..
