Episode notes
INSIGHT

Microplastics Research Emergence

  • Microplastics and nanoplastics research gained prominence about 10 years ago, focusing on water and plastic degradation.
  • Increased awareness stems from plastic presence in waterways and concerns about weathering and breakdown.
INSIGHT

Plastic Degradation and Ocean Impact

  • Plastic degrades slowly, potentially taking decades or centuries, creating micro-particulate smog in oceans.
  • Ocean currents form large eddies filled with visible and microscopic plastic debris, impacting environmental and human health.
INSIGHT

Biodegradable Plastics and Ocean Temperature

  • Biodegradable plastics require specific temperatures to degrade effectively.
  • Cool ocean temperatures hinder their breakdown, contributing to plastic accumulation.
