A book covering so broad a field as this cannot well be based entirely upon the knowledge and observation of any single individual. For this reason, I have unhesitatingly drawn upon the literature on the subject, selecting the mate rial which I considered most appropriate. In order to achieve conciseness the book is arranged as follows: Chapter I gives certain principles to be borne in mind when making a test and a description of certain simple sampling apparatuses. Each of the succeeding chapters is devoted to a material or family of materials which can cause an exposure. The information given about each material i s : its occurrence and uses, certain physical properties, clinical symptomatology it produces in man, the physiological re sponses of man to various concentrations, concentrations allowable in the air of the workplace and a simple method of estimation in air. Sufficient references have also been given so that anyone interested in continuing his studies further may proceed to more exhaustive sources of information. Certain useful constants, formulas and instructions for preparation of standard solutions will be found in the appendix. Acknowledgment is made to H. C. Johnson, L. Press and A. J. Holden for their kind assistance. 3 POTENTIAL INDUSTRIAL HEALTH HAZARDS
