I thought the problem is not the printing ink/toner, but, rather, the
(chlorine?) bleach used to make the paper white? Book publishers
(especially US) also often identify the paper used as being 'acid-free',
but what about other paper?

Book publishers identify paper as acid free to indicate that the paper
doesn't self destruct in the way that non acid free paper does.

Ah ... and here I thought it was environmentally friendly somehow...

I would be surprised if there is any more than a smidgeon of bleach
left in the paper a day or two after it is laid.

but bad news for all the paperbacks I have hoarded over the last forty
odd years, most are terminally yellowed.

And they disintegrate even more terminally when you open them.
I now have a number of them sitting neatly in plastic folders, but
referring to them is another matter. The compost bin beckons...

Newsprint paper is made from simple wood-pulp. Glossy papers, such as
used for magazines etc. have coatings of fine white mineral pigments
such as china clay, chalk or titanium dioxide, in order to give a
smoother, whiter surface that is both glossy and better for printing
on.

In the past, many of the pigments in coloured inks use for magazines
were toxic, but so much paper gets recycled these days, and health &
safety considerations are so important, that I doubt very much if any
modern inks are toxic.

The main issue is the likely re-use of the material in food packaging,
and so its all produced to a standard that will meet these specs after
recycling, AIUI.
