Comments on: Li et al. (2019) “Bioelectrochemical Systems for Groundwater Remediation: The Development Trend and Research Front Revealed by Bibliometric Analysis” Water, 11, 1532

This is a critical comment on a bibliometric analysis by Li et al. (2019) examining bioelectrochemical systems for groundwater remediation. Ho argues that Li et al. employed inappropriate search strategies and methodology, including imprecise keyword searches that retrieved irrelevant documents and failure to filter results using article front pages (title, abstract, author keywords). The analysis reveals that 95% of retrieved documents were unrelated to the stated topic, and top-cited articles lacked any of the specified search terms, demonstrating fundamental flaws in the original bibliometric approach.
