It might just be a typo, 2012 would make more sense.
In my field there was an influential 2001 paper from a reputable journal that reported an erroneous pKa value of 3.6, instead of 6.3, and people to this day are reporting the wrong pKa citing that paper. They then wonder why they don’t get the desired precipitation that would have occurred had the pKa been indeed lower.
