Polystyrene nanoparticles stimulate the growth and microcystin synthesis of Microcystis aeruginosa
Nanoplastics are ubiquitous in freshwater ecosystems and pose a threat to environmental and human health. They inhibit the growth of Microcystis aeruginosa and increase its microcystin content, yet the underlying mechanisms remain elusive. Here we investigated the effects of nano-polystyrene on the growth, photosynthesis, microcystin content and transcriptome of M. aeruginosa. The results showed that 10 mg/L nano-polystyrene slightly inhibited the growth during the first two days of exposure…
