A good place to start is Levy and Wegman's Occ. Health,
2nd ed., publ by Little Brown. Also Maxcy-Rosenau's
Textbook of Preventive Medicine, 13th ed. (that's the
title) edited by John Last has hundreds of pages on the
subject. Also major texts by Tarcher and by Zenz. The
major federal source is NIOSH in Cicinnati. OSHA has
the generally agreed upon relationships but is quite con-
servative. For the latest info you should consult the
journals, esp. Am. J. of Industrial Med. and British J.
of Indu. Med. Finally, call the occupational health clinic
(if there is one) at your local or state univ. (I'm sure
Case Western has someone).
	Good luck.
