Damages of aged-PVC microplastics exceed the enhanced resistance of chlorella pyrenoidosa induced by phosphorus limitation

Key Points

• Aged-PVC microplastics significantly damage chlorella pyrenoidosa, indicating a serious environmental threat.
• The study highlights that phosphorus limitation does not provide expected resistance to the toxicity of aged-PVC microplastics.
• Assessment using microalgal toxicity tests emphasizes the challenges posed by aging in microplastics over time.
• These findings support the need for further research on the ecological impacts of microplastics on aquatic systems.
