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.
In a December 12 news release, Chemosphere acknowledged the quality concerns and laid out steps it will take to improve its editorial process. Those include improvements to article vetting and peer review, along with assurances that articles will be retracted if there’s evidence of policy breaches.
“We believe that these measures will help us regain the standard of research integrity that has always been so important to us,” the news release stated.
Questioned conclusions
The removal from the Web of Science on December 16 came just a day after a correction was issued on the black plastic study. That study claimed to find a “high exposure potential” of toxic flame retardants in plastic household items, particularly kitchen utensils, that are made from recycled electronics. The findings sparked a firestorm of media coverage imploring people to immediately throw away any black plastic utensils in their kitchens.
