Try 'CHEMICAL EXPOSURE and HUMAN HEALTH' by Cynthia Wilson

Toluene is a chemical that seems to be in many common products. The symptoms can be
'allergy like' but also seem to be very consistant with people who suffer from MCS
(multiple chemical sensitivity AKA environmental illness, 20th century disease).
If you want more info, literature review, etc on MCS e-mail back.
