Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain. ACS cannot be held responsible for errors or consequences arising from the use of information contained in these “Just Accepted” manuscripts.

Abstract
19
Previous studies of uptake and effects of nanoplastics by marine organisms have been conducted at
20
what may be unrealistically high concentrations. This is a consequence of the analytical challenges
21
in tracking plastic particles in organisms at environmentally relevant concentrations and highlights
22
the need for new approaches. Here, we present pulse exposures of 14C-radiolabeled nanopolystyrene
23
to a commercially important mollusk, Pecten maximus, at what have been predicted to be
24
environmentally relevant concentrations (
