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

<p>Welcome to this <italic>Analytical Methods</italic> 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.</p>
