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 free 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 accessible to all readers and 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

Plastic debris is a prolific contaminant effecting freshwater and marine ecosystems across the globe.

20

Of growing environmental concern are 'microplastics' and 'nanoplastics', encompassing tiny particles

21

of plastic derived from manufacturing and macroplastic fragmentation. Pelagic zooplankton are

22

susceptible to consuming microplastics, however the threat posed to larvae of commercially

23

important bivalves is currently unknown. We exposed Pacific oyster (Crassostrea gigas) larvae (3-24

24

d.p.f.) to polystyrene particles spanning 70 nm˗20 µm in size, including plastics with differing surface

25

properties, and tested the impact of microplastics on larval feeding and growth. The frequency and

26

magnitude of plastic ingestion over 24 hours varied by larval age and size of polystyrene particle 1 ACS Paragon Plus Environment
