   2 corrections applied: The Leslie et al. 2022 study tested 22 volunteers and detected plastic particles in 17 of them (about 77%); '77 of 22' is impossible (the 77 was the percentage mistakenly used as a count). | The 2002 Nature 'Geology of mankind' letter was authored by Crutzen alone; the co-authored piece was the 2000 IGBP Global Change Newsletter article 'The Anthropocene'. Body text conflated the two.

   Before

   found microplastics in the blood of 77 of 22 healthy adult volunteers tested | He published the idea in a short letter in Nature in 2002, co-authored...

   After

   found microplastics in the blood of 17 of 22 healthy adult volunteers tested (about 77%) | He published the idea first in a 2000 article co-authored with biologist Eugene Stoermer and then in a short letter in Nature in 2002

   Why: Fixed impossible '77 of 22' figure to the correct 17 of 22 (77%), and corrected the Crutzen authorship/publication timeline (2000 IGBP co-authored article vs. 2002 solo Nature letter). Both corrections verified present in body text and bibliography (which correctly lists both the 2000 Crutzen & Stoermer IGBP piece and the 2002 solo Nature letter); FAQ has no mention of the microplastic study count or the co-authorship claim, so no FAQ fix was needed.
