Addendum to “Editorial Retraction of the Report ‘Environmentally relevantconcentrations of microplastic particles influence larval fish ecology,’ by O. M.Lönnstedt and P. Eklöv”
AI summary Read the abstract
This addendum announced that Uppsala University's investigation found both authors of a high-profile microplastics-fish larval behavior study committed research misconduct, confirming the earlier retraction of the Science paper and emphasizing the importance of data integrity in microplastic research.
Science has been informed that Uppsala University has completed its investigation into the study by Lonnstedt and Eklov, published in Science on 3 June 2016 and retracted on 3 May 2017. (The Retraction ran online on 3 May and in print on 26 May 2017.) The investigation has found that both authors

Editorial retraction
AI summary Read the abstract
This editorial retraction removed from Science the paper by Lönnstedt and Eklöv on microplastic effects on larval perch, citing lack of ethical approval, absence of original data, and widespread lack of clarity about experimental conduct as found by Sweden's Central Ethical Review Board. The retraction highlights the critical importance of data integrity and ethical oversight in environmental toxicology research.
RETRACTED: Environmentally relevant concentrations of microplastic particles influence larval fish ecology
AI summary Read the abstract
Note: This paper has been retracted by the journal. The original study claimed that microplastic exposure at environmental levels harmed larval fish development and behavior, but the findings were later deemed unreliable. Retracted studies should not be used as evidence for microplastic health effects, though the topic of microplastic impacts on early-life fish development continues to be studied by other research groups.
On Some Possible Ramifications of the “Microplastics in Fish” Case
AI summary Read the abstract
This paper examines a high-profile case of research misconduct in environmental science — a 2016 Science paper on microplastics and fish behavior that was retracted after findings could not be reproduced — and discusses the broader implications for scientific integrity in the field of plastic pollution research.
Retraction Note: An assessment of physiological and health responses in Catla catla fingerlings after polystyrene microplastic exposure
AI summary Read the abstract
This is a retraction notice for a study on polystyrene microplastic exposure in Catla catla fish, withdrawn after data irregularities were identified, including figures that appeared to be reused from other papers representing different conditions or species. The retraction underscores the importance of data integrity in microplastics research, where replication and accuracy are critical.
