Unfortunately, that reference is 12 years old. About 10 years ago, the
US government implemented much stricter regulation on inks that
contained heavy metals. Between that and the increasing cost
effectiveness of soy ink, many newpapers switched. You will still find
some in small volume papers and in non-newsprint publications
(magazines, advertisements, etc). Several studies have been done on the
non-toxic nature of these inks and the newpaper itself.
According to http://www.graphicartsonline.com/article/CA446851.html, as
of 2004 about 95% of the daily newpaper circulars in the US used Soy
ink. You can check with your local source if you are concerned.
Note that I think there is still probably some risk of the ink leeching
into soil from papercrete. But given that if I was not using it, it
would be in the landfill I don't really see this as a big down side.
