TL;DR: The fluorescence region integration technique and protein secondary structures revealed the reasons for the poor dewatering performance in the presence of CeO2 NPs, including the enhanced amount of soluble microbial by-product-like material and the low value of the α-helix/(β-sheet + random coil).

TL;DR: Three-dimensional excitation-emission fluorescence spectra revealed that tyrosine (LB-EPS) and aromatic (TB-Eps) protein-like substances formed after CeO2 NP exposure, and Fourier transform infrared spectroscopy results indicated the susceptibility of -OH and -NH2 in EPS hydroxyl and amine groups to CeO 2 NPs.

TL;DR: N nanoplastics have potential to disrupt the basic ecological functions of biofilms in aquatic environments and the antioxidant activity of biofilm was enhanced as indicated by the increased total antioxidant capacity (T-AOC).

TL;DR: It is demonstrated that the inhibitory effect of Ag-containing NPs on denitrification in sediments depends on their morphology and type, implying that the stability and toxicity of Ag/S NPs should be considered with caution.

TL;DR: Exposure to high concentrations of CuO NPs has the potential to shape wastewater biofilm bacterial community structure, which might result in microbial community function fluctuations.
