Although the fate of nanoplastics (< 100 nm) in freshwater systems is increasingly well studied, much less is known about its potential threats to cyanobacterial blooms, the ultimate phenomenon of eutrophication occurring world-wide. Previous studies have evaluated the consequences of nanoplastics increasing the membrane permeability of microbes, there is no direct evidence for interactions between nanoplastics and microcystin; intracellular hepatotoxins produced by some genera of cyanobacteria....

Recently, there has been increasing global concerns about the ecological impact of micro- and nano-sized polystyrene particles in marine environments. However, the potential threats of polystyrene nanoparticles to primary producers in freshwater systems remain unclear. Here, we explore the metabolite profiles and signaling pathways of freshwater cyanobacterium Synechococcus elongatus in response to short-term (48 h) amino-modified polystyrene nanoparticle (PS-NH2; 50 nm) exposure. We demonstrate...

Anaerobic treatment systems play an important role in treating nanoplastic-containing wastewater, such as textile dyeing wastewater. However, the influence of nanoplastics on anaerobic granular sludge (AGS), a key parameter determining the performance of anaerobic bioreactors, has not received sufficient attention. In this study, inhibition and recovery of AGS performances in response to short-term polystyrene (PS) nanoparticle exposure were investigated. Results showed that cationic PS nanopart...

Abstract Microplastics and nanoplastics in aquatic systems have become a global concern because of their persistence and adverse consequences to ecosystems and potentially human health. Though wastewater treatment plants (WWTPs) are considered a potential source of microplastics in the environment, the role of extracellular polymeric substances (EPS) of activated sludge on the fate of nanoplastics is not clear. In this study, the role of EPS in the influence of polystyrene nanoparticles (PS-NPs)...
