Abstract
    Weiss et al. (Reports, 2 July 2021, p. 107) incorrectly conclude that the residence time for floating microplastic stock at the ocean surface is ~2.4 years. We contend that this conclusion is fundamentally flawed, because the residence time is obtained through dividing a published oceanic stock of plastic debris by a doubtable river microplastic flux estimated by the authors.
