How Problems with Microplastics in Research and Application Can be Overcome: Lessons From the Experience of Plastics...

Area of Science:

• Environmental Science
• Toxicology
• Materials Science

Background:

• Micro- and nanoplastics (MNPs) present growing human health and environmental concerns.
• Methodological limitations in hazard identification and exposure assessment impede reliable MNP risk characterization.
• Complex MNP compositions necessitate robust, harmonized assessment protocols for regulatory action.

Purpose of the Study:

• To address research networking and standardization needs for MNP analysis.
• To establish requirements for risk-minimizing plastic design and labeling.
• To develop concrete recommendations for MNP risk management.

Main Methods:

• Convened an expert workshop within the Horizon 2020 PlasticsFatE project.
• Focused on analytical workflow standardization and hazard assessment.
• Gathered input on plastic design and toxic substance labeling.

Main Results:

• Proposed a graduated approach for methodological unification in particle and hazard analysis.
• Recommended standardization in MNP monitoring protocols.
• Advocated for risk-minimizing plastic design and mandatory toxic substance labeling.

Conclusions:

• Standardization and harmonization are essential for reliable MNP risk assessment.
• Proactive strategies, including design and labeling, are needed to mitigate MNP risks.
• Evidence-based regulation requires reproducible and harmonized MNP analysis methods.
