Generating environmental sampling and testing data for micro- and nanoplastics for use in life cycle impact...

Area of Science:

• Environmental Science
• Chemical Engineering
• Ecotoxicology

Background:

• Quantifying plastic pollution and its health impacts is ongoing, typically from a receptor perspective.
• Life Cycle Assessment (LCA) requires an emitter perspective, highlighting a data gap for micro- and nanoplastics (MNPs).

Purpose of the Study:

• To evaluate current data gathering and reporting for MNP exposure studies for LCA relevance.
• To propose requirements for harmonized data to facilitate MNP integration into LCA.

Main Methods:

• Analysis of existing field and laboratory data gathering and reporting approaches for MNPs.
• Development of a three-level data recording and reporting requirement framework for LCA.

Main Results:

• Receptor-oriented MNP studies often lack suitable, harmonized data for LCA.
• Existing data collection methods are insufficient for LCA inputs, necessitating improved sampling, testing, and reporting.

Conclusions:

• Implementing standardized data requirements will enable better integration of MNP impacts into LCA.
• This integration will allow for comprehensive assessment and comparison of plastic emission impacts with other environmental issues.
