PE was deployed in the Outer Oslofjord (Norway) for 21 days, before exposing the mussels to both virgin (PE-V) and weathered PE (PE-W) particles. The mussels ingested both types of particles, but significantly more weathered particles were ingested than virgin (p =.0317), based on PE dosed by weight (mg ml) but not when considering particle number (PE-V: 1.18 ± 0.16 particles ml; PE-W 1.86 ± 0.66 particles ml). PE particle ingestion resulted in structural changes to the gills and digestive gland, as well as necrosis in other tissues such as the mantle. No differences were found regarding the degree of tissue alteration between PE-virgin and PE-weathered exposures. This current study illustrates the importance of using weathered particles in microplastic exposure studies to reflect the behaviour of plastic particles after entering the marine environment. The observed tissue alterations demonstrate the potential adverse effects to mussels exposed to microplastic particles This work was supported by the Norwegian Research Council (NFR; Project No. 225203) Peer Reviewed 2018-07-09T11:24:00Z 2018-07-09T11:24:00Z 2018-06 2018-07-09T11:24:00Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.1016/j.scitotenv.2018.01.141 issn: 0048-9697 e-issn: 1879-1026 Science of the Total Environment 626(1): 1310-1318 (2018) http://hdl.handle.net/10261/167477 10.1016/j.scitotenv.2018.01.141 https://doi.org/10.1016/j.scitotenv.2018.01.141 Sí open Elsevier
