Granite (http://tanbrown.org) sealers and (http://maplered.com) resins for the chemically sensitive

Does anyone have any information in the use of Granite (http://tanbrown.org) in housing for chemically sensitive individuals? The Granite (http://tanbrown.org) itself should be inert, but how about the resins that are now used on most Granite (http://tanbrown.org) s? I would also expect that the sealers would be toxic to the chemically sensitive, at least on the day applied and (http://maplered.com) until fully volatized. I've looked a lot of places on the web, but haven't found any info so far.
