Temperature and ethanol synergistically enhance microplastic release from disposable cups: mechanistic insights and health risk assessment of typical plastics

Key Points

• Microplastic release significantly increases with combined exposure to ethanol and high temperature, raising concerns about environmental contamination.
• The study found a 2.5-fold increase in microplastic particles at elevated temperatures and ethanol concentrations.
• Experimental analysis utilized controlled lab settings to assess microplastic release mechanisms under various conditions.
• Such findings highlight the need for stricter regulations on disposable plastic products to protect ecosystem health and human safety.
