TL;DR: It is shown that both positively and negatively charged nanoplastics can accumulate in Arabidopsis thaliana, providing direct evidence that nanoplastic accumulate in plants, depending on their surface charge.

TL;DR: It is demonstrated that amino-modified polystyrene nanoplastics (PS-NH2) promote microcystin synthesis and release from Microcystis aeruginosa, a dominant species causing cyanobacterial blooms, even without the change of coloration, and proposed that the presence of nanoplastic in freshwater ecosystems might enhance the threat of eutrophication to aquatic ecology and human health.

TL;DR: The Fourier transform infrared spectroscopy results show that the protein secondary structures in EPS were changed by PS-NPs and lead to the bioflocculation of activated sludge, which provides a better understanding on the fate of nanoplastics in WWTPs.

TL;DR: PS-NH2 exposure causes disruption of glutathione metabolism and damage to the membrane hydrophobic core of S. elongatus, which enhanced the understanding of the ecological risks of plastic debris to freshwater environments.

TL;DR: The role of NPs in the natural environment as a carrier of antibiotics may provide an alternative for antibiotic inputs from inland water to coastal marine water, which would not only change the environmental fate and ecotoxicology of antibiotics and NPs, but also pose challenges to the safety of coastal aquaculture and marine ecosystem.
