The Potential Risks of Biodegradable Plastics: Professor Jiang Hui's Team at Peking University Reports for the First Time on the Reproductive Toxicity Induced by Polylactic Acid Micro/Nanoplastics
On January 27, 2025, Professor Jiang Hui's team at Peking University First Hospital published a research paper in the authoritative materials science journal ACS Nano, titled "Polylactic acid micro/nanoplastic exposure induces male reproductive toxicity by disrupting spermatogenesis and mitochondrial dysfunction in mice." This study for the first time revealed the reproductive toxicity of PLA micro/nanoplastics (PLA-MP/NP) in male mice, suggesting that the toxic mechanisms may be similar to those of traditional petroleum-based microplastics. These findings provide a theoretical basis for assessing the environmental risks of biodegradable plastics.
