Repeated oral exposure to polyethylene microplastics induces thyroid toxicity in rats: Evidence from in vivo toxicokinetics and multi-omics analyses.
The widespread use and non-biodegradable nature of polyethylene microplastics (PE-MPs) have prompted significant public concern about their safety. However, the mechanisms underlying their adverse effects on human health remain largely elusive. Male rats were orally administered 34-μm PE-MPs via daily gavage for 28 con...
