In a groundbreaking study that challenges the assumed safety of biodegradable plastics, researchers from Anhui Medical University and Fudan University in China have uncovered alarming evidence that the breakdown products of polylactic acid (PLA) — a widely used “eco-friendly” bioplastic — can cross the placental barrier and impair fetal development in mice. Published in PLOS Biology, this research unveils critical insights into the potential developmental toxicity of oligomeric lactic acid (OLA) nanoplastics that form as PLA degrades, underscoring the urgent need to reevaluate the safety profiles of plastics marketed as sustainable alternatives.
