An article [1] published on "Environmental Research" has reused EDX spectra on the figure 3. The "Spectra 1" and the "Spectra 2" have identical noise, as well as the "Spectra 3" and "Spectra 4" have identical noise, too, suggesting these spectra are reused.

A study published on "Environmental Research" was partly founded by the King Saud University, and concerns were raised about potential authorship-for-sale in this article.
Recently, the 5GH team found that 26 articles massively reuse spectra and images, and 5 other articles have questionable (hand-draw style) spectra.
Songling Wang (王松灵), a leading dental scientist in China, and a fellow of the Chinese Academy of Science, has published over 200 academic articles until recently. However, on most of his publications, Wang spells his name as "Songlin Wang" instead of "Songling Wang", which is likely due to his dialect accent.
