The publisher of a high-profile, now-corrected study on black plastics has been removed from a critical index of academic journals amid questions about quality criteria, according to a report by Retraction Watch.
On December 16, Clarivate—a scholarly publication analytics company—removed the journal Chemosphere from its platform, the Web of Science, which is a key index for academic journals. The indexing platform tracks citations and calculates journal “impact factors,” a proxy for relevance in its field. It’s a critical metric not only for the journals but for the academic authors of the journal’s articles, who use the score in their pursuit of promotions and research funding.
To be included in the Web of Science, Clarivate requires journals to follow editorial quality criteria. According to Retraction Watch, Chemosphere has retracted eight articles this month and published 60 expressions of concern since April.
