Improving microplastics source apportionment: a role for microplastic morphology and taxonomy?

Paul Helm discusses the need for a more detailed level of classification to aid in identifying source contributions of microplastics, providing direction on the implementation of management activities to reduce the occurrence of microplastics in the environment and enabling monitoring of the effectiveness of those actions.

Analytical challenges associated with the determination of microplastics in the environment

Rob Hale considers the significant analytical challenges posed through the use of plastics and the resulting small fragments they yield – microplastics – which are a major contaminant of concern for both human health and ecosystems worldwide.

On the harmonization of methods for measuring the occurrence, fate and effects of microplastics

Welcome to this Analytical Methods themed issue on microplastics in the environment, guest edited by Chelsea M. Rochman, Fiona Regan and Richard C. Thompson. The editors hope that this editorial will facilitate discussions that lead toward harmonized methods that are informed by hypotheses, and ultimately produce data that can be synthesized and used to inform effective local and global policies that prevent and mitigate microplastics.
