This thesis explores the potential impacts that can occur in Atlantic cod and blue mussels resulting from the ingestion of microplastic particles based on a review of previously published studies. This thesis summarizes the differing lifestyles and feeding strategies of both species and how these features are either beneficial or unfavourable with respect to the ingestion of microplastics. The is review identified a total of twenty potential effects were found to occur in both species when they were exposed to microplastics. Twelve of the effects were shared between Atlantic cod and blue mussels; however, overall observed responses varied between the two species. Results showed that blue mussels seem to face a greater exposure to microplastics than Atlantic cod. The type and severity of effects were found to differ depending upon the amount of particles ingested and the duration of exposure. As this is a somewhat new area of research much information remains unknown. This is especially true in the case of Atlantic cod as there is much less data and completed studies compared to those which is available for blue mussels.
